Sybex Book Review 1 Flashcards
Confidentiality, integrity, and availability are typically viewed as the primary goals and objectives of a security infrastructure. Which of the following is not considered a violation of confidentiality?
A. Stealing passwords using a keystroke logging tool
B. Eavesdropping on wireless network communications
C. Hardware destruction caused by arson
D. Social engineering that tricks a user into providing personal information to a false website
C. Hardware destruction is a violation of availability and possibly integrity. Violations of confidentiality include stealing passwords, eavesdropping, and social engineering.
Security governance requires a clear understanding of the objectives of the organization as the core concepts of security. Which of the following contains the primary goals and objectives of security?
A. A network’s border perimeter
B. The CIA Triad
C. AAA services
D. Ensuring that subject activities are recorded
B. The primary goals and objectives of security are confidentiality, integrity, and availability, commonly referred to as the CIA Triad. The other options are incorrect. A security infrastructure needs to establish a network’s border perimeter security, but that is not a primary goal or objective of security. AAA services is a common component of secured systems, which can provide support for accountability, but the primary goals of security remain the elements of the CIA Triad. Ensuring that subject activities are recorded is the purpose of auditing, but that is not a primary goal or objective of security.
James recently discovered an attack taking place against his organization that prevented employees from accessing critical records. What element of the CIA Triad was violated?
A. Identification
B. Availability
C. Encryption
D. Layering
B. Availability means that authorized subjects are granted timely and uninterrupted access to objects. Identification is claiming an identity, the first step of AAA services. Encryption is protecting the confidentiality of data by converting plain text into cipher text. Layering is the use of multiple security mechanisms in series.
Optimally, security governance is performed by a board of directors, but smaller organizations may simply have the CEO or CISO perform the activities of security governance. Which of the following is true about security governance?
A. Security governance ensures that the requested activity or access to an object is possible given the rights and privileges assigned to the authenticated identity.
B. Security governance is used for efficiency. Similar elements are put into groups, classes, or roles that are assigned security controls, restrictions, or permissions as a collective.
C. Security governance is a documented set of best IT security practices that prescribes goals and requirements for security controls and encourages the mapping of IT security ideals to business objectives.
D. Security governance seeks to compare the security processes and infrastructure used within the organization with knowledge and insight obtained from external sources.
D. Security governance seeks to compare the security processes and infrastructure used within the organization with knowledge and insight obtained from external sources. The other statements are not related to security governance. Authorization ensures that the requested activity or access to an object is possible given the rights and privileges assigned to the authenticated identity. Abstraction is used for efficiency. Similar elements are put into groups, classes, or roles that are assigned security controls, restrictions, or permissions as a collective. COBIT is a documented set of best IT security practices crafted by the Information Systems Audit and Control Association (ISACA) that prescribes goals and requirements for security controls and encourages the mapping of IT security ideals to business objectives.
You have been tasked with crafting a long-term security plan that is fairly stable. It needs to define the organization’s security purpose. It also needs to define the security function and align it to the goals, mission, and objectives of the organization. What are you being asked to create?
A. Tactical plan
B. Operational plan
C. Strategic plan
D. Rollback plan
C. A strategic plan is a long-term plan that is fairly stable. It defines the organization’s security purpose. It defines the security function and aligns it to the goals, mission, and objectives of the organization. The tactical plan is a midterm plan developed to provide more details on accomplishing the goals set forth in the strategic plan or can be crafted ad hoc based on unpredicted events. An operational plan is a short-term, highly detailed plan based on the strategic and tactical plans. It is valid or useful only for a short time. A rollback plan is a means to return to a prior state after a change does not meet expectations.
Annaliese’s organization is undergoing a period of increased business activity where they are conducting a large number of mergers and acquisitions. She is concerned about the risks associated with those activities. Which of the following are example of those risks? (Choose all that apply.)
A. Inappropriate information disclosure
B. Increased worker compliance
C. Data loss
D. Downtime
E. Additional insight into the motivations of inside attackers
F. Failure to achieve sufficient return on investment (ROI)
A, C, D, F. Acquisitions and mergers place an organization at an increased level of risk. Such risks include inappropriate information disclosure, data loss, downtime, and failure to achieve sufficient return on investment (ROI). Increased worker compliance is not a risk, but a desired security precaution against the risks of acquisitions. Additional insight into the motivations of inside attackers is not a risk, but a potential result of investigating breaches or incidents related to acquisitions.
Which security framework was initially crafted by a government for domestic use but is now an international standard, which is a set of recommended best practices for optimization of IT services to support business growth, transformation, and change; which focuses on understanding how IT and security need to be integrated with and aligned to the objectives of an organization; and which is often used as a starting point for the crafting of a customized IT security solution within an established infrastructure?
A. ITIL
B. ISO 27000
C. CIS
D. CSF
A. Information Technology Infrastructure Library (ITIL) was initially crafted by the British government for domestic use but is now an international standard, which is a set of recommended best practices for core IT security and operational processes, and is often used as a starting point for the crafting of a customized IT security solution. The other options were not crafted by the British government. ISO 27000 is a family group of international standards that can be the basis of implementing organizational security and related management practices. The Center for Internet Security (CIS) provides OS, application, and hardware security configuration guides. NIST Cybersecurity Framework (CSF) is designed for critical infrastructure and commercial organizations and consists of five functions: Identify, Protect, Detect, Respond, and Recover. It is a prescription of operational activities that are to be performed on an ongoing basis for the support and improvement of security over time.
A security role is the part an individual plays in the overall scheme of security implementation and administration within an organization. What is the security role that has the functional responsibility for security, including writing the security policy and implementing it?
A. Senior management
B. Security professional
C. Custodian
D. Auditor
B. The security professional has the functional responsibility for security, including writing the security policy and implementing it. Senior management is ultimately responsible for the security maintained by an organization and should be most concerned about the protection of its assets. The custodian role is assigned to the user who is responsible for the tasks of implementing the prescribed protection defined by the security policy and senior management. An auditor is responsible for reviewing and verifying that the security policy is properly implemented and the derived security solutions are adequate.
Control Objectives for Information and Related Technology (COBIT) is a documented set of best IT security practices crafted by the Information Systems Audit and Control Association (ISACA). It prescribes goals and requirements for security controls and encourages the mapping of IT security ideals to business objectives. COBIT is based on six key principles for governance and management of enterprise IT. Which of the following are among these key principles? (Choose all that apply.)
A. Holistic Approach
B. End-to-End Governance System
C. Provide Stakeholder Value
D. Maintaining Authenticity and Accountability
E. Dynamic Governance System
A, B, C, E. The COBIT key principles are: Provide Stakeholder Value (C), Holistic Approach (A), Dynamic Governance System (E), Governance Distinct From Management (not listed), Tailored to Enterprise Needs (not listed), and End-to-End Governance System (B). The concept of maintaining authenticity and accountability are good security ideas, but not a COBIT key principle.
In today’s business environment, prudence is mandatory. Showing due diligence and due care is the only way to disprove negligence in an occurrence of loss. Which of the following are true statements? (Choose all that apply.)
A. Due diligence is establishing a plan, policy, and process to protect the interests of an organization.
B. Due care is developing a formalized security structure containing a security policy, standards, baselines, guidelines, and procedures.
C. Due diligence is the continued application of a security structure onto the IT infrastructure of an organization.
D. Due care is practicing the individual activities that maintain the security effort.
E. Due care is knowing what should be done and planning for it.
F. Due diligence is doing the right action at the right time.
A, D. Due diligence is establishing a plan, policy, and process to protect the interests of an organization. Due care is practicing the individual activities that maintain the security effort. The other options are incorrect, they have the terms inverted. The corrected statements are as follows: Due diligence is developing a formalized security structure containing a security policy, standards, baselines, guidelines, and procedures. Due care is the continued application of a security structure onto the IT infrastructure of an organization. Due diligence is knowing what should be done and planning for it. Due care is doing the right action at the right time.
Security documentation is an essential element of a successful security program. Understanding the components is an early step in crafting the security documentation. Match the following components to their respective definitions.
- Policy
- Standard
- Procedure
- Guideline
I. A detailed, step-by-step how-to document that describes the exact actions necessary to implement a specific security mechanism, control, or solution.
II. A document that defines the scope of security needed by the organization and discusses the assets that require protection and the extent to which security solutions should go to provide the necessary protection.
III. A minimum level of security that every system throughout the organization must meet.
IV. Offers recommendations on how security requirements are implemented and serves as an operational guide for both security professionals and users.
V. Defines compulsory requirements for the homogenous use of hardware, software, technology, and security controls.
A. 1 – I; 2 – IV; 3 – II; 4 - V
B. 1 – II; 2 – V; 3 – I; 4 - IV
C. 1 – IV; 2 – II; 3 – V; 4 - I
D. 1 – V; 2 – I; 3 – IV; 4 - III
B. A policy is a document that defines the scope of security needed by the organization and discusses the assets that require protection and the extent to which security solutions should go to provide the necessary protection. A standard defines compulsory requirements for the homogenous use of hardware, software, technology, and security controls. A procedure is a detailed, step-by-step how-to document that describes the exact actions necessary to implement a specific security mechanism, control, or solution. A guideline offers recommendations on how security requirements are implemented and serves as an operational guide for both security professionals and users. III is the definition of a baseline, which was not included as a component option.
STRIDE is often used in relation to assessing threats against applications or operating systems. When confidential documents are exposed to unauthorized entities, which element of STRIDE is used to reference that violation?
A. S
B. T
C. R
D. I
E. D
F. E
D. When confidential documents are exposed to unauthorized entities, this is described by the I in STRIDE, which represents information disclosure. The elements of STRIDE are spoofing, tampering, repudiation, information disclosure, denial of service, and elevation of privilege.
A development team is working on a new project. During the early stages of systems development, the team considers the vulnerabilities, threats, and risks of their solution and integrates protections against unwanted outcomes. What concept of threat modeling is this?
A. Threat hunting
B. Proactive approach
C. Qualitative approach
D. Adversarial approach
B. This scenario describes a proactive approach to threat modeling, which is also known as the defensive approach. A reactive approach or adversarial approach to threat modeling takes place after a product has been created and deployed. There is no threat modeling concept known as qualitative approach. Qualitative is typically associated with a form of risk assessment.
Supply chain risk management (SCRM) is a means to ensure that all the vendors or links in the supply chain are reliable, trustworthy, reputable organizations. Which of the following are true statements? (Choose all that apply.)
A. Each link in the supply chain should be responsible and accountable to the next link in the chain.
B. Commodity vendors are unlikely to have mined their own metals or processed the oil for plastics or etched the silicon of their chips.
C. If the final product derived from a supply chain meets expectations and functional requirements, it is assured to not have unauthorized elements.
D. Failing to properly secure a supply chain can result in flawed or less reliable products, or even embedded listing or remote control mechanisms.
A, B, D. These statements are true: (A) Each link in the supply chain should be responsible and accountable to the next link in the chain; (B) Commodity vendors are unlikely to have mined their own metals or processed the oil for plastics or etched the silicon of their chips; and (D) Failing to properly secure a supply chain can result in flawed or less reliable products, or even embedded listing or remote control mechanisms. The remaining option is incorrect. Even if a final product seems reasonable and performs all necessary functions, that does not provide assurance that it is secure or that it was not tampered with somewhere in the supply chain.
Your organization has become concerned with risks associated with the supply chain of their retail products. Fortunately, all coding for their custom product is done in-house. However, a thorough audit of a recently completed product revealed that a listening mechanism was integrated into the solution somewhere along the supply chain. The identified risk is associated with what product component in this scenario?
A. Software
B. Services
C. Data
D. Hardware
D. Though not explicitly stating hardware, this scenario describes a typical and potential risk of a supply chain, that a hardware risk results in the presence of a listening mechanism in the final product. This scenario does not provide information that would indicate that the supply chain risk is focused on software, services, or data.
Cathy’s employer has asked her to perform a documentation review of the policies and procedures of a third-party supplier. This supplier is just the final link in a software supply chain. Their components are being used as a key element of an online service operated for high-end customers. Cathy discovers several serious issues with the vendor, such as failing to require encryption for all communications and not requiring multifactor authentication on management interfaces. What should Cathy do in response to this finding?
A. Write up a report and submit it to the CIO.
B. Void the ATO of the vendor.
C. Require that the vendor review their terms and conditions.
D. Have the vendor sign an NDA.
B. In this scenario, Cathy should void the authorization to operate (ATO) of this vendor. This situation describes the fact that the vendor is not meeting minimal security requirements which are necessary to the protection of the service and its customers. Writing a report is not a sufficient response to this discovery. You may have assumed Cathy does or does not have the authority to perform any of the other options, but there is no indication of Cathy’s position in the organization. It is reasonable for a CEO to ask the CISO to perform such an evaluation. Regardless, the report should be submitted to the CISO, not the CIO, whose focus is primarily on ensuring that information is used effectively to accomplish business objectives, not that such use is secure. Reviewing terms and conditions will not make any difference in this scenario, as those typically apply to customers, not internal operations. And reviewing does not necessarily cause a change or improvement to insecure practices. A vendor-signed NDA has no bearing on this scenario.
Whenever an organization works with a third party, its supply chain risk management (SCRM) processes should be applied. One of the common requirements is the establishment of minimum security requirements of the third party. What should these requirements be based on?
A. Existing security policy
B. Third-party audit
C. On-site assessment
D. Vulnerability scan results
A. Minimum security requirements should be modeled on your existing security policy. This is based on the idea that when working with a third party, that third party should have at least the same security as your organization. A third-party audit is when a third-party auditor is brought in to perform an unbiased review of an entity’s security infrastructure. This audit may reveal where there are problems, but the audit should not be the basis of minimum security requirements for a third party. On-site assessment is when you visit the site of the organization to interview personnel and observe their operating habits. This is not the basis for establishing minimum security requirements for a third party. Vulnerability scan results, like third-party audits, may reveal concerns, but it is not the basis for establishing minimum security requirements for a third party.
It’s common to pair threats with vulnerabilities to identify threats that can exploit assets and represent significant risks to the organization. An ultimate goal of threat modeling is to prioritize the potential threats against an organization’s valuable assets. Which of the following is a risk-centric threat-modeling approach that aims at selecting or developing countermeasures in relation to the value of the assets to be protected?
A. VAST
B. SD3+C
C. PASTA
D. STRIDE
C. Process for Attack Simulation and Threat Analysis (PASTA) is a seven-stage threat modeling methodology. PASTA is a risk-centric approach that aims at selecting or developing countermeasures in relation to the value of the assets to be protected. Visual, Agile, and Simple Threat (VAST) is a threat modeling concept that integrates threat and risk management into an Agile programming environment on a scalable basis. Microsoft uses a Security Development Lifecycle (SDL) with the motto “Secure by Design, Secure by Default, Secure in Deployment and Communication” (also known as SD3+C). STRIDE is a threat categorization scheme developed by Microsoft.
The next step after threat modeling is reduction analysis. Reduction analysis is also known as decomposing the application, system, or environment. The purpose of this task is to gain a greater understanding of the logic of the product, its internal components, as well as its interactions with external elements. Which of the following are key components to identify when performing decomposition? (Choose all that apply.)
A. Patch or update versions
B. Trust boundaries
C. Dataflow paths
D. Open vs. closed source code use
E. Input points
F. Privileged operations
G. Details about security stance and approach
B, C, E, F, G. The five key concepts of decomposition are trust boundaries, dataflow paths, input points, privileged operations, and details about security stance and approach. Patch or update version management is an important part of security management in general; it is just not a specific component of decomposition. Determining open vs. closed source code use is not an element of decomposition.
Defense in depth is simply the use of multiple controls in a series. No one control can protect against all possible threats. Using a multilayered solution allows for numerous, different controls to guard against whatever threats come to pass. Which of the following are terms that relate to or are based on defense in depth? (Choose all that apply.)
A. Layering
B. Classifications
C. Zones
D. Realms
E. Compartments
F. Silos
G. Segmentations
H. Lattice structure
I. Protection rings
A, B, C, D, E, F, G, H, I. All of the listed options are terms that relate to or are based on defense in depth: layering, classifications, zones, realms, compartments, silos, segmentations, lattice structure, and protection rings.
You have been tasked with overseeing the security improvement project for your organization. The goal is to reduce the current risk profile to a lower level without spending considerable amounts of money. You decide to focus on the largest concern mentioned by your CISO. Which of the following is likely the element of the organization that is considered the weakest?
A. Software products
B. Internet connections
C. Security policies
D. Humans
D. Regardless of the specifics of a security solution, humans are often considered the weakest element. No matter what physical or logical controls are deployed, humans can discover ways to avoid them, circumvent or subvert them, or disable them. Thus, it is important to take into account the humanity of your users when designing and deploying security solutions for your environment. Software products, internet connections, and security policies can all be vulnerabilities or otherwise areas of security concern, but they are not considered the most common weakest element of an organization.
Due to recent organization restructuring, the CEO believes that new workers should be hired to perform necessary work tasks and support the mission and goals of the organization. When seeking to hire new employees, what is the first step?
A. Create a job description.
B. Set position classification.
C. Screen candidates.
D. Request résumés.
A. The first step in hiring new employees is to create a job description. Without a job description, there is no consensus on what type of individual needs to be found and hired. Crafting job descriptions is the first step in defining security needs related to personnel and being able to seek out new hires. From the job description, a determination can be made as to the education, skills, experience, and classification required by the applicant. Then a job posting can be made to request the submission of résumés. Then, candidates can be screened to see if they meet the requirements and if they have any disqualifications.
_________________ is the process of adding new employees to the organization, having them review and sign policies, be introduced to managers and coworkers, and be trained in employee operations and logistics.
A. Reissue
B. Onboarding
C. Background checks
D. Site survey
B. Onboarding is the process of adding new employees to the organization, having them review and sign policies, be introduced to managers and coworkers, and be trained in employee operations and logistics. Reissue is a certification function when a lost certificate is provided to the user by extracting it from the escrow backup database or when a certificate is altered to extend its expiration date. Background checks are used to verify that a job applicant is qualified but not disqualified for a specific work position. A site survey is used to optimize the placement of wireless access points (WAPs) to provide reliable connectivity throughout the organization’s facilities.
After repeated events of retraining, a particular worker was caught for the fourth time attempting to access documents that were not relevant to their job position. The CSO decides this was the last chance and the worker is to be fired. The CSO reminds you that the organization has a formal termination process that should be followed. Which of the following is an important task to perform during the termination procedure to reduce future security issues related to this ex-employee?
A. Return the exiting employee’s personal belongings.
B. Review the nondisclosure agreement.
C. Evaluate the exiting employee’s performance.
Cancel the exiting employee’s parking permit
B. A termination process often focuses on eliminating an employee who has become problematic, whether that employee is committing crimes or just violating company policy. Once the worker is fired, the company has little direct control over that person. So, the only remaining leverage is legal, which often relates to a nondisclosure agreement (NDA). Hopefully, reviewing and reminding the ex-employee about their signed NDA will reduce future security issues, such as confidential data dissemination. Returning the exiting employee’s personal belongings is not really an important task to protect the company’s security interests. Evaluating the exiting employee’s performance could be done via an exit interview, but that was not mentioned in this scenario. Often when an adversarial termination occurs, an exit interview is not feasible. Canceling an exiting employee’s parking permit is not a high security priority for most organizations, at least not in comparison to the NDA.
Which of the following is a true statement in regard to vendor, consultant, and contractor controls?
A. Using business email compromise (BEC) is a means to ensure that organizations providing services maintain an appropriate level of service agreed on by the service provider, vendor, or contractor and the customer organization.
B. Outsourcing can be used as a risk response option known as acceptance or appetite.
C. Multiparty risk exists when several entities or organizations are involved in a project. The risk or threats are often due to the variations of objectives, expectations, timelines, budgets, and security priorities of those involved.
D. Risk management strategies implemented by one party do not cause additional risks against or from another party.
C. Option C is correct: Multiparty risk exists when several entities or organizations are involved in a project. The risk or threats are often due to the variations of objectives, expectations, timelines, budgets, and security priorities of those involved. The other statements are false. Their corrected and thus true versions would be: (A) Using service- level agreements (SLAs) is a means to ensure that organizations providing services maintain an appropriate level of service agreed on by the service provider, vendor, or contractor and the customer organization; (B) Outsourcing can be used as a risk response option known as transference or assignment; and (D) Risk management strategies implemented by one party may in fact cause additional risks to or from another party.
Match the term to its definition:
- Asset
- Threat
- Vulnerability
- Exposure
- Risk
I. The weakness in an asset, or the absence or the weakness of a safeguard or countermeasure.
II. Anything used in a business process or task.
III. Being susceptible to asset loss because of a threat; there is the possibility that a vulnerability can or will be exploited.
IV. The possibility or likelihood that a threat will exploit a vulnerability to cause harm to an asset and the severity of damage that could result.
V. Any potential occurrence that may cause an undesirable or unwanted outcome for an organization or for a specific asset.
K. 1-II, 2-V, 3-I, 4-III, 5-IV
L. 1-I, 2-II, 3-IV, 4-II, 5-V
M. 1-II, 2-V, 3-I, 4-IV, 5-III
N. 1-IV, 2-V, 3-III, 4-II, 5-I
A. An asset is anything used in a business process or task. A threat is any potential occurrence that may cause an undesirable or unwanted outcome for an organization or for a specific asset. A vulnerability is the weakness in an asset, or the absence or the weakness of a safeguard or countermeasure. An exposure is being susceptible to asset loss because of a threat; there is the possibility that a vulnerability can or will be exploited. Risk is the possibility or likelihood that a threat will exploit a vulnerability to cause harm to an asset and the severity of damage that could result.
While performing a risk analysis, you identify a threat of fire and a vulnerability of things being flammable because there are no fire extinguishers. Based on this information, which of the following is a possible risk?
A. Virus infection
B. Damage to equipment
C. System malfunction
D. Unauthorized access to confidential information
B. The threat of a fire and the vulnerability of a lack of fire extinguishers lead to the risk of damage to equipment. This scenario does not relate to virus infection or unauthorized access. Equipment damaged by fire could be considered a system malfunction, but that option is not as direct as “damage to equipment.”
During a meeting of company leadership and the security team, discussion focuses on defining the value of assets in dollars, inventorying threats, predicting the specific amount of harm of a breach, and determining the number of times a threat could cause harm to the company each year. What is being performed?
A. Qualitative risk assessment
B. Delphi technique
C. Risk avoidance
D. Quantitative risk assessment
D. This scenario is describing the activity of performing a quantitative risk assessment. The question describes the determination of asset value (AV) as well as the exposure factor (EF) and the annualized rate of occurrence (ARO) for each identified threat. These are the needed values to calculate the annualized loss expectancy (ALE), which is a quantitative factor. This is not an example of a qualitative risk assessment, since specific numbers are being determined rather than relying on ideas, reactions, feelings, and perspectives. This is not the Delphi technique, which is a qualitative risk assessment method that seeks to reach an anonymous consensus. This is not risk avoidance, since that is an optional risk response or treatment, and this scenario is only describing the process of risk assessment.
You have performed a risk assessment and determined the threats that represent the most significant concern to your organization. When evaluating safeguards, what is the rule that should be followed in most cases?
A. The expected annual cost of asset loss should not exceed the annual costs of safeguards.
B. The annual costs of safeguards should equal the value of the asset.
C. The annual costs of safeguards should not exceed the expected annual cost of asset value loss.
D. The annual costs of safeguards should not exceed 10 percent of the security budget.
C. The annual costs of safeguards should not exceed the expected annual cost of asset value loss. The other statements are not rules to follow. (A) The annual cost of the safeguard should not exceed the annual cost of the asset value or its potential value loss. (B) The cost of the safeguard should be less than the value of the asset. (D) There is no specific maximum percentage of a security budget for the cost of a safeguard. However, the security budget should be used efficiently to reduce overall risk to an acceptable level.
During a risk management project, an evaluation of several controls determines that none are cost-effective in reducing the risk related to a specific important asset. What risk response is being exhibited by this situation?
A. Mitigation
B. Ignoring
C. Acceptance
D. Assignment
C. When controls are not cost effective, they are not worth implementing. Thus, risk acceptance is the risk response in this situation. Mitigation is the application of a control; that was not done in this scenario. Ignoring risk occurs when no action, not even assessment or control evaluation, is performed in relation to a risk. Since controls were evaluated in this scenario, this is not ignoring risk. Assignment is the transfer of risk to a third party; that was not done in this scenario.
During the annual review of the company’s deployed security infrastructure, you have been reevaluating each security control selection. How is the value of a safeguard to a company calculated?
A. ALE before safeguard – ALE after implementing the safeguard – annual cost of safeguard
B. ALE before safeguard * ARO of safeguard
C. ALE after implementing safeguard + annual cost of safeguard – controls gap
D. Total risk – controls gap
A. The value of a safeguard to an organization is calculated by ALE before safeguard – ALE after implementing the safeguard – annual cost of safeguard [(ALE1 – ALE2) – ACS]. This is known as the cost/benefit equation for safeguards. The other options are incorrect. (B) This is an invalid calculation. (C) This is an invalid calculation. (D) This is the concept formula for residual risk: total risk – controls gap = residual risk
Which of the following are valid definitions for risk? (Choose all that apply.)
A. An assessment of probability, possibility, or chance
B. Anything that removes a vulnerability or protects against one or more specific threats
C. Risk = threat * vulnerability
D. Every instance of exposure
E. The presence of a vulnerability when a related threat exists
A, C, D. Statements of A, C, and D are all valid definitions of risk. The other two statements are not definitions of risk. (B) Anything that removes a vulnerability or protects against one or more specific threats is considered a safeguard or a countermeasure, not a risk. (E) The presence of a vulnerability when a related threat exists is an exposure, not a risk. A risk is a calculation of the probability of occurrence and the level of damage that could be caused if an exposure is realized (i.e., actually occurs).
A new web application was installed onto the company’s public web server last week. Over the weekend a malicious hacker was able to exploit the new code and gained access to data files hosted on the system. This is an example of what issue?
A. Inherent risk
B. Risk matrix
C. Qualitative assessment
D. Residual risk
A. This situation is describing inherent risk. Inherent risk is the level of natural, native, or default risk that exists in an environment, system, or product prior to any risk management efforts being performed. The new application had vulnerabilities that were not mitigated, thus enabling the opportunity for the attack. This is not a risk matrix. A risk matrix or risk heat map is a form of risk assessment that is performed on a basic graph or chart, such as a 3×3 grid comparing probability and damage potential. This is not a qualitative risk assessment, since this scenario does not describe any evaluation of the risk of the new code. This is not residual risk, since no controls were implemented to reduce risk. Residual risk is the leftover risk after countermeasures and safeguards are implemented in reponse to original or total risk.
Your organization is courting a new business partner. During the negotiations the other party defines several requirements of your organization’s security that must be met prior to the signing of the SLA and business partners agreement (BPA). One of the requirements is that your organization demonstrate their level of achievement on the Risk Maturity Model (RMM). The requirement is specifically that a common or standardized risk framework is adopted organization-wide. Which of the five possible levels of RMM is being required of your organization?
A. Preliminary
B. Integrated
C. Defined
D. Optimized
C. The level of RMM named Defined requires that a common or standardized risk framework be adopted organization-wide. This is effectively level 3. The first level of RMM is not listed as an option; it is ad hoc, which is the chaotic starting point. Preliminary is RMM level 2, which demonstrates loose attempts to follow risk management processes but each department may perform risk assessment uniquely. Integrated is RMM level 4, where risk management operations are integrated into business processes, metrics are used to gather effectiveness data, and risk is considered an element in business strategy decisions. Optimized is RMM level 5, where risk management focuses on achieving objectives rather than just reacting to external threats, increasing strategic planning toward business success rather than just avoiding incidents, and reintegrating lessons learned into the risk management process.
The Risk Management Framework (RMF) provides a disciplined, structured, and flexible process for managing security and privacy risk that includes information security categorization; control selection, implementation, and assessment; system and common control authorizations; and continuous monitoring. The RMF has seven steps or phases. Which phase of the RMF focuses on determining whether system or common controls based on a determination that the risk to organizational operations and assets, individuals, other organizations, and the nation are reasonable?
A. Categorize
B. Authorize
C. Assess
D. Monitor
B. The RMF phase 6 is Authorize whether system or common controls based on a determination that the risk to organizational operations and assets, individuals, other organizations, and the nation is acceptable (or reasonable). The phases of RMF are (1) Prepare, (2) Categorize, (3) Select, (4) Implement, (5) Assess, (6) Authorize, and (7) Monitor. (A) RMF phase (2) is categorize the system and the information processed, stored, and transmitted by the system based on an analysis of the impact of loss. (C) RMF phase (5) is assess the controls to determine if the controls are implemented correctly, operating as intended, and producing the desired outcomes with respect to satisfying the security and privacy requirements. (D) RMF phase (7) is monitor the system and the associated controls on an ongoing basis to include assessing control effectiveness, documenting changes to the system and environment of operation, conducting risk assessments and impact analyses, and reporting the security and privacy posture of the system.
Company proprietary data are discovered on a public social media posting by the CEO. While investigating, a significant number of similar emails were discovered to have been sent to employees, which included links to malicious sites. Some employees report that they had received similar messages to their personal email accounts as well. What improvements should the company implement to address this issue? (Choose two.)
A. Deploy a web application firewall.
B. Block access to personal email from the company network.
C. Update the company email server.
D. Implement multifactor authentication (MFA) on the company email server.
E. Perform an access review of all company files.
F. Prohibit access to social networks on company equipment.
B, F. The leaking of company proprietary data may have been caused by the content of emails received by workers. The computers of workers who clicked links from the suspicious emails may have been infected by malicious code. This malicious code may have exfiltrated documents to the social media site. This issue could occur whether workers were on company computers on the company network, on company computers on their home network, or on personal computers on their home network (especially if the workers copied company files to their personal machines to work from home). Blocking access to social media sites and personal email services from the company network reduces the risk of this same event occurring again. For example, if the suspicious emails are blocked from being received by company email servers and accounts, they could still be received into personal email accounts. Though not mentioned, blocking access to the malicious URLs would be a good security defense as well. This issue is not addressed by deploying a web application firewall, updating the company email server, using MFA on the email server, or performing an access review of company files. Although all of these options are good security practices in general, they do not relate specifically to this issue.
What process or event is typically hosted by an organization and is targeted to groups of employees with similar job functions?
A. Education
B. Awareness
C. Training
D. Termination
C. Training is teaching employees to perform their work tasks and to comply with the security policy. Training is typically hosted by an organization and is targeted to groups of employees with similar job functions. (A) Education is an endeavor in which students and users learn much more than they actually need to know to perform their work tasks. Education is most often associated with users pursuing certification or seeking job promotion or career advancement. Most education programs are not hosted by the employer but by training organizations or colleges or universities. Education is not provided to workers in groups based on their job positions. (B) Awareness establishes a common baseline or foundation of security understanding across the entire organization and focuses on key or basic topics and issues related to security that all employees must understand. Although it is provided by the organization, it is not targeted to groups of workers since it applies to all employees. (D) Termination is usually targeted at individuals rather than groups of workers with similar job positions. Though large layoff events might fire groups of similar workers, this option is not as accurate as training.
Which of the following could be classified as a form of social engineering attack? (Choose all that apply.)
A. A user logs in to their workstation and then decides to get a soda from the vending machine in the stairwell. As soon as the user walks away from their workstation, another person sits down at their desk and copies all the files from a local folder onto a network share.
B. You receive an email warning about a dangerous new virus spreading across the internet. The message tells you to look for a specific file on your hard drive and delete it, since it indicates the presence of the virus.
C. A website claims to offer free temporary access to their products and services but requires that you alter the configuration of your web browser and/or firewall in order to download the access software.
D. A secretary receives a phone call from a person claiming to be a client who is running late to meet the CEO. The caller asks for the CEO’s private cell phone number so that they can call them.
B, C, D. The activity described in option A is an opportunistic unauthorized access attack, which is not a social engineering attack since there was no interaction with the victim, just the opportunity when the victim walked away. The activities described in options B (hoax), C (phishing, hoax, watering hole attack), and D (vishing) are all examples of social engineering attacks.
Often a _____________ is a member of a group who decides (or is assigned) to take charge of leading the adoption and integration of security concepts into the group’s work activities. _____________ are often non-security employees who take up the mantle to encourage others to support and adopt more security practices and behaviors.
A. CISO(s)
B. Security champion(s)
C. Security auditor(s)
D. Custodian(s)
B. The correct answer for these blanks is security champion(s). Often a security champion is a member of a group who decides (or is assigned) to take charge of leading the adoption and integration of security concepts into the group’s work activities. Security champions are often non-security employees who take up the mantle to encourage others to support and adopt more security practices and behaviors. The other options are incorrect. A CISO, or chief information security officer, defines and enforces security throughout the organization. The security auditor is the person who manages security logging and reviews the audit trails for signs of compliance or violation. The custodian is the security role that accepts assets from owners and then, based on the owner-assigned classifications, places the asset in the proper IT container where the proper security protections are provided.
The CSO has expressed concern that after years of security training and awareness programs, the level of minor security violations has actually increased. A new security team member reviews the training materials and notices that it was crafted four years ago. They suggest that the materials be revised to be more engaging and to include elements that allow for the ability to earn recognition, team up with coworkers, and strive toward a common goal. They claim these efforts will improve security compliance and foster security behavior change. What is the approach that is being recommended?
A. Program effectiveness evaluation
B. Onboarding
C. Compliance enforcement
D. Gamification
D. Security awareness and training can often be improved through gamification. Gamification is a means to encourage compliance and engagement by integrating common elements of game play into other activities, such as security compliance and behavior change. This can include rewarding compliance behaviors and potentially punishing violating behaviors. Many aspects of game play can be integrated into security training and adoption, such as scoring points, earning achievements or badges (i.e., earn recognition), competing with others, cooperating with others (i.e., team up with coworkers), following a set of common/standard rules, having a defined goal, seeking rewards, developing group stories/experiences, and avoiding pitfalls or negative game events. (A) Program effectiveness evaluation is using some means of verification, such as giving a quiz or monitoring security incident rate changes over time, to measure whether the training is beneficial or a waste of time and resources. This question starts by indicating that security incidents are on the rise, which shows that prior training was ineffective. But the recommendations to change the training are gamification focused. (B) Onboarding is the process of adding new employees to the organization. This is not the concept being described in this scenario. (C) Compliance enforcement is the application of sanctions or consequences for failing to follow policy, training, best practices, and/or regulations.
