26
What BS7799 Part 2 outlined?
How a security program (ISMS) can be set up and maintained
27
Why the companies seek for ISO/IEC 27001?
Check Information Security Management System (ISMS) requirements and attests to the organization's compliance level
28
What are the four architecture types that TOGAF framework can develop?
Business architecture, Data architecture, Applications architecture and Technology architecture
29
What is the difference between an ISMS and an enterprise security architecture?
An ISMS outlines the controls that need to be put into place (risk management, vulnerability management, business continuity planning, data protection, auditing, configuration management, physical security, etc.) and provides direction on how those controls should be managed throughout their life cycle
The enterprise security architecture illustrates how these components are to be integrated into the different layers of the current business environment
30
What Business enablement means?
Business enablement means the core business processes are integrated into the security operating model—they are standards based and follow a risk tolerance criteria.
Help the business to achieve their goals but adding security controls to make it work securely.
31
What Process enablement means?
So while business enablement means "we can do new stuff," process enhancement means "we can do stuff better."
32
What Security Effectiveness means?
It's a way to determine how useful the current security solutions and architecture as a whole are performing (using SLA, metrics, ROI...)
33
What is the difference between Enterprise and System Architectures
?
An enterprise architecture addresses the structure of an organization. A system architecture addresses the structure of software and computing components.
34
COBIT five key principles
Meeting stakeholder needs
Covering the enterprise end to end
Applying a single integrated framework
Enabling a holistic approach
Separating governance from management
35
What is the different between COSO IC and COBIT?
COSO IC deals more at the strategic level, while COBIT focuses more at the operational level
36
What is the different between Polymorphic and Metamorphic malware
A polymorphic virus decrypts its code, runs that code, and then when propagating itself encrypts the decrypted code with a different key. A metamorphic virus simply runs its code and then when propagating itself mutates its code into different but functionally identical code

Personally identifiable information (PII) is data that can be used to uniquely identify, contact, or locate a single person or can be used with other sources to uniquely identify a single individual.
50
What is privacy?
Privacy is an individual's right to determine what data they would like others to know about themselves, which people are permitted to know that data, and when those people can access it.
51
Federal Privacy Act of 1974
Agencies can gather information about individuals, but it must be relevant and necessary to the agency's official functions. In addition, an agency cannot share people's private information. If it does, private citizens have the right to sue that agency to protect their privacy.
52
The Federal Information Security Management Act (FISMA)
FISMA requires agency program officials, chief information officers, and inspectors general (IGs) to conduct annual reviews of the agency's information security program and report the results to the Office of Management and Budget (OMB).

56
What are the three policy types?
The organizational security policy provides scope and direction for all future security activities within the organization
An issue-specific policy, also called a functional policy, addresses specific security issues that management feels need more detailed explanation and attention to make sure a comprehensive structure is built and all employees understand how they are to comply with these security issues.
A system-specific policy presents the management's decisions that are specific to the actual computers, networks, and applications.
57
What is the difference between strategic and tactical goal?
A strategic goal can be viewed as the ultimate endpoint, while tactical goals are the steps necessary to achieve it.
58
What is the difference between security policies, standards, procedures, baselines, and guidelines
Security policy - Is an overall general statement produced by senior management that dictates what role security plays within the organization.
Standard - Refer to mandatory activities, actions, or rules.
Procedure - Detailed step-by-step tasks that should be performed to achieve a certain goal.
Baseline - Refers to a point in time that is used as a comparison for future changes.
Guideline - Recommended actions and operational guides to users, IT staff, operations staff, and others when a specific standard does not apply.
59
