Q

Rodney, a security engineer, is viewing this record from the firewall logs:

UTC 04/05/2018 03:09:15809 AV Gateway Alert
136.127.92.171 80 -> 10.16.10.14 60818
Gateway Anti-Virus Alert:
XPACK.A_7854 (Trojan) blocked.
Which of the following can be observed from this log information?
❍ A. The victim’s IP address is 136.127.92.171
❍ B. A download was blocked from a web server
❍ C. A botnet DDoS attack was blocked
❍ D. The Trojan was blocked, but the file was not

A

The Answer: B. A download was blocked from a web server
A traffic flow from a web server port number (80) to a device port (60818)
indicates that this traffic flow originated on port 80 of the web server. A
file download is one of the most common ways to deliver a Trojan, and
this log entry shows that the file containing the XPACK.A_7854 Trojan
was blocked.
The incorrect answers:
A. The victim’s IP address is 136.127.92.171
The format for this log entry uses an arrow to differentiate between the
attacker and the victim. The attacker IP address is 136.127.92.171, and the
victim’s IP address is 10.16.10.14.
C. A botnet DDoS attack was blocked
A botnet attack would not commonly include a Trojan horse as part of a
distributed denial of service (DDoS) attack.
D. The Trojan was blocked, but the file was not
A Trojan horse attack involves malware that is disguised as legitimate
software. The Trojan malware and the file are the same entity, so there isn’t
a way to decouple the malware from the file

Q
A user connects to a third-party website and receives this message:
Your connection is not private. 
NET::ERR_CERT_INVALID
Which of the following attacks would be the MOST likely reason 
for this message?
❍ A. Brute force
❍ B. DoS
❍ C. On-path
❍ D. Disassociation
A

The Answer: C. On-path
An on-path attack is often associated with a third-party who is actively
intercepting network traffic. This entity in the middle would not be able
to provide a valid SSL certificate for a third-party website, and this error
would appear in the browser as a warning.
The incorrect answers:
A. Brute force
A brute force attack is commonly associated with password hacks. Brute
force attacks would not cause the certificate on a website to be invalid.
B. DoS
A DoS (Denial of Service) attack would prevent communication to a
server and most likely provide a timeout error. This error is not related to a
service availability issue.
D. Disassociation
Disassociation attacks are commonly associated with wireless networks,
and they usually cause disconnects and lack of connectivity. The error
message in this example does not appear to be associated with a network
outage or disconnection.

Q

An attacker calls into a company’s help desk and pretends to be the
director of the company’s manufacturing department. The attacker
states that they have forgotten their password and they need to have the
password reset quickly for an important meeting. What kind of attack
would BEST describe this phone call?
❍ A. Social engineering
❍ B. Tailgating
❍ C. Vishing
❍ D. On-path

A

The Answer: A. Social engineering
A social engineering attack takes advantage of authority and urgency
principles in an effort to convince someone else to circumvent normal
security controls.
The incorrect answers:
B. Tailgating
A tailgating attack follows someone else with proper credentials through a
door. This allows the attack to gain access to an area that’s normally locked.
C. Vishing
Vishing (voice phishing) attacks use the phone to obtain private
information from others. In this example, the attacker was not asking for
confidential information.
D. On-path
An on-path attack commonly occurs without any knowledge to the parties
involved, and there’s usually no additional notification that an attack is
underway. In this question, the attacker contacted the help desk engineer
directly.

❍ A. EAP-TLS
❍ B. PEAP
❍ C. EAP-TTLS
❍ D. EAP-MSCHAPv2

A

The Answer: C. EAP-TTLS
EAP-TTLS (Extensible Authentication Protocol - Tunneled Transport
Layer Security) allows the use of multiple authentication protocols
transported inside of an encrypted TLS (Transport Layer Security) tunnel.
This allows the use of any authentication while maintaining confidentiality
with TLS.
The incorrect answers:
A. EAP-TLS
EAP-TLS does not provide a mechanism for using multiple
authentication types within a TLS tunnel.

Q

A security team has been provided with a non-credentialed vulnerability
scan report created by a third-party. Which of the following would they
expect to see on this report?
❍ A. A summary of all files with invalid group assignments
❍ B. A list of all unpatched operating system files
❍ C. The version of web server software in use
❍ D. A list of local user accounts

A

The Answer: C. The version of web server software in use
A scanner like Nmap can query services and determine version numbers
without any special rights or permissions, which makes it well suited for
non-credentialed scans.
The incorrect answers:
A. A summary of all files with invalid group assignments
Viewing file permissions and rights requires authentication to the
operating system, so you would not expect to see this information if the
scan did not have credentials.
B. A list of all unpatched operating system files
Viewing detailed information about the operating system files requires
authentication to the OS, and an uncredentialed scan does not have those
permissions.
D. A list of local user accounts
Local user accounts are usually protected by the operating system, so you
would need to have credentials to view this information.

Q

A file server has a full backup performed each Monday at 1 AM.
Incremental backups are performed at 1 AM on Tuesday, Wednesday,
Thursday, and Friday. The system administrator needs to perform a full
recovery of the file server on Thursday afternoon. How many backup sets
would be required to complete the recovery?
❍ A. 2
❍ B. 3
❍ C. 4
❍ D. 1

A

The Answer: C. 4
Each incremental backup will archive all of the files that have changed
since the last full or incremental backup. To complete this full restore, the
administrator will need the full backup from Monday and the incremental
backups from Tuesday, Wednesday, and Thursday.
The incorrect answers:
A. 2
If the daily backup was differential, the administrator would only need the
full backup and the differential backup from Thursday.
B. 3
Since the incremental backup only archives files that have changed, he will
need all three daily incremental backups as well as Monday’s full backup.
D. 1
To recover incremental backups, you’ll need the full backup and all
incremental backups since the full backup.

was announced last week and none of the servers are patched yet. Which
of the following best describes this result?
❍ A. Exploit
❍ B. Credentialed
❍ C. Zero-day attack
❍ D. False negative

A

The Answer: D. False negative
A false negative is a result that fails to detect an issue when one
actually exists.
The incorrect answers:
A. Exploit
An exploit is an attack against a vulnerability. Vulnerability scans do not
commonly attempt to exploit the vulnerabilities that they identify.
B. Credentialed
A credentialed scan would authenticate to the operating system and have
access to files that would normally only be available to authorized users.
C. Zero-day attack
A zero-day attack focuses on previously unknown vulnerabilities. In this
example, the vulnerability scan isn’t an attack, and the vulnerabilities are
already known and patches are available.

useful authentication controls when used in conjunction with other
authentication factors.
The incorrect answers:
B. Least privilege
Least privilege is a security principle that limits access to resources based
on a person’s job role. Least privilege is managed through security policy
and is not an authentication control.
C. Role-based awareness training
Role-based awareness training is specialized training that is based on a
person’s control of data within an organization. This training is not part of
the authentication process.
D. Separation of duties
A security policy that separates duties across different individuals is
separation of duties. This separation is not part of the authentication
process.

A company hires a large number of seasonal employees, and their system access should normally be disabled when the employee leaves the company. The security administrator would like to verify that their systems cannot be accessed by any of the former employees. Which of the following would be the BEST way to provide this verification? ❍ A. Confirm that no unauthorized accounts have administrator access ❍ B. Validate the account lockout policy ❍ C. Validate the processes and procedures for all outgoing employees ❍ D. Create a report that shows all authentications for a 24-hour period
The Answer: C. Validate the processes and procedures for all outgoing employees The disabling of an employee account is commonly part of the offboarding process. One way to validate an offboarding policy is to perform an audit of all accounts and compare active accounts with active employees. The incorrect answers: A. Confirm that no unauthorized accounts have administrator access It’s always a good idea to periodically audit administrator accounts, but this audit won’t provide any validation that all former employee accounts have been disabled. B. Validate the account lockout policy Account lockouts occur when a number of invalid authentication attempts have been made to a valid account. Disabled accounts would not be locked out because they are not currently valid accounts. D. Create a report that shows all authentications for a 24-hour period A list of all authentications would be quite large, and it would not be obvious to see which authentications were made with valid accounts and which authentications were made with former employee accounts.

``` Which of the following risk management strategies would include the purchase and installation of an NGFW? ❍ A. Transference ❍ B. Mitigation ❍ C. Acceptance ❍ D. Risk-avoidance ```
The Answer: B. Mitigation Mitigation is a strategy that decreases the threat level. This is commonly done through the use of additional security systems and monitoring, such as an NGFW (Next-Generation Firewall). The incorrect answers: A. Transference Transference would move the risk from one entity to another. Adding an NGFW would not transfer any risk to another party. C. Acceptance The acceptance of risk is a position where the owner understands the risk and has decided to accept the potential results. D. Risk-avoidance With risk-avoidance, the owner of the risk decides to stop participating in a high-risk activity. This effectively avoids the risky activity and prevents any future issues.

Which of the following would be the BEST way to confirm the secure baseline of a deployed application instance? ❍ A. Compare the production application to the sandbox ❍ B. Perform an integrity measurement ❍ C. Compare the production application to the previous version ❍ D. Perform QA testing on the application instance
The Answer: B. Perform an integrity measurement An integrity measurement is designed to check for the secure baseline of firewall settings, patch levels, operating system versions, and any other security components associated with the application. These secure baselines may vary between different application versions. The incorrect answers: A. Compare the production application to the sandbox A sandbox is commonly used as a development environment. Security baselines in a production environment can be quite different when compared to the code in a sandbox. C. Compare the production application to the previous version The newer version of an application may have very different security requirements than previous versions. D. Perform QA testing on the application instance QA (Quality Assurance) testing is commonly used for finding bugs and verifying application functionality. The primary task of QA is not generally associated with verifying security baselines.

A company encourages users to encrypt all of their confidential materials on a central server. The organization would like to enable key escrow as a backup. Which of these keys should the organization place into escrow? ❍ A. Private ❍ B. CA ❍ C. Session ❍ D. Public
The Answer: A. Private With asymmetric encryption, the private key is used to decrypt information that has been encrypted with the public key. To ensure continued access to the encrypted data, the company must have a copy of each private key. The incorrect answers: B. CA A CA (Certificate Authority) key is commonly used to validate the digital signature from a trusted CA. This is not commonly used for user data encryption. C. Session Session keys are commonly used temporarily to provide confidentiality during a single session. Once the session is complete, the keys are discarded. Session keys are not used to provide long-term data encryption. D. Public In asymmetric encryption, a public key is already available to everyone. It would not be necessary to escrow a public key

0. A manufacturing company would like to use an existing router to separate a corporate network and a manufacturing floor that use the same physical switch. The company does not want to install any additional hardware. Which of the following would be the BEST choice for this segmentation? ❍ A. Connect the corporate network and the manufacturing floor with a VPN ❍ B. Build an air gapped manufacturing floor network ❍ C. Use personal firewalls on each device ❍ D. Create separate VLANs for the corporate network and the manufacturing floor
The Answer: D. Create separate VLANs for the corporate network and the manufacturing floor Creating VLANs (Virtual Local Area Networks) will segment a network without requiring additional switches. The incorrect answers: A. Connect the corporate network and the manufacturing floor with a VPN A VPN (Virtual Private Network) would encrypt all information between the two networks, but it would not provide any segmentation. This process would also commonly require additional hardware to provide VPN connectivity. B. Build an air gapped manufacturing floor network An air gapped network would require separate physical switches on each side of the gap, and this would require the purchase of an additional switch. C. Use personal firewalls on each device While personal firewalls provide protection for individual devices, they do not segment networks. It’s also uncommon for personal firewalls to be installed on manufacturing equipment.

When a home user connects to the corporate VPN, they are no longer able to print to their local network printer. Once the user disconnects from the VPN, the printer works normally. Which of the following would be the MOST likely reason for this issue? ❍ A. The VPN uses IPSec instead of SSL ❍ B. Printer traffic is filtered by the VPN client ❍ C. The VPN is stateful ❍ D. The VPN tunnel is configured for full tunnel
The Answer: D. The VPN tunnel is configured for full tunnel A split tunnel is a VPN (Virtual Private Network) configuration that only sends a portion of the traffic through the encrypted tunnel. A split tunnel would allow work-related traffic to securely traverse the VPN, and all other traffic would use the non-tunneled option. In this example, the printer traffic is being redirected through the VPN instead of the local home network because of the non-split/full tunnel. The incorrect answers: A. The VPN uses IPSec instead of SSL There are many protocols that can be used to send traffic through an encrypted tunnel. IPsec is commonly used for site-to-site VPN connections, and SSL (Secure Sockets Layer) is commonly used for enduser VPN connections. However, either protocol can technically be used for any VPN tunnel, and the choice of protocol would have no difference on the operation of the local printer. B. Printer traffic is filtered by the VPN client VPN clients are usually tasked with sending traffic unfiltered through the encrypted tunnel. Although data could be filtered at some point along the communication path, it’s not commonly filtered by the VPN client. C. The VPN is stateful A stateful communication is commonly associated with firewalls, and it refers to the firewall’s ability to track traffic flows. Stateful communication would not be a technology commonly associated with a VPN, and it would not be part of the user’s printing issue.

``` Which cryptographic method is used to add trust to a digital certificate? ❍ A. X.509 ❍ B. Hash ❍ C. Symmetric encryption ❍ D. Digital signature ```
The Answer: D. Digital signature A certificate authority will digitally sign a certificate to add trust. If you trust the certificate authority, you can then trust the certificate. The incorrect answers: A. X.509 The X.509 standard defines the structure of a certificate. This standard format makes it easy for everyone to view the contents of a certificate, but it doesn’t provide any additional trust. B. Hash A hash can help verify that the certificate has not been altered, but it does not provide additional third-party trust. C. Symmetric encryption Symmetric encryption has the same issue as asymmetric encryption. The information in a certificate commonly needs to be viewable by others.

A corporate security team would like to consolidate and protect the private keys across all of their web servers. Which of these would be the BEST way to securely store these keys? ❍ A. Use an HSM ❍ B. Implement full disk encryption on the web servers ❍ C. Use a TPM ❍ D. Upgrade the web servers to use a UEFI BIOS
The Answer: A. Use an HSM An HSM (Hardware Security Module) is a high-end cryptographic hardware appliance that can securely store keys and certificates for all devices. The incorrect answers: B. Implement full disk encryption on the web servers Full-disk encryption would only protect the keys if someone does not have the proper credentials, and it won’t help consolidate all of the web server keys to a central point. C. Use a TPM A TPM (Trusted Platform Module) is used on individual devices to provide cryptographic functions and securely store encryption keys. Individual TPMs would not provide any consolidation of web server private keys. D. Upgrade the web servers to use a UEFI BIOS A UEFI (Unified Extensible Firmware Interface) BIOS (Basic Input/ Output System) does not provide any additional security or consolidation features for web server private keys.

A security administrator has configured a virtual machine in a screened subnet with a guest login account and no password. Which of the following would be the MOST likely reason for this configuration? ❍ A. The server is a honeypot for attracting potential attackers ❍ B. The server is a cloud storage service for remote users ❍ C. The server will be used as a VPN concentrator ❍ D. The server is a development sandbox for third-party programming projects
The Answer: A. The server is a honeypot for attracting potential attackers A screened subnet is a good location to configure services that can be accessed from the Internet, and building a system that can be easily compromised is a common tactic for honeypot systems. The incorrect answers: B. The server is a cloud storage service for remote users Although cloud storage is a useful service, configuring storage on a server with an open guest account is not a best practice. C. The server will be used as a VPN concentrator VPN (Virtual Private Networking) concentrators should be installed on secure devices, and configuring an open guest account would not be considered a secure configuration. D. The server is a development sandbox for third-party programming projects It would not be secure to configure a development sandbox on a system with an open guest account.

A company's outgoing email server currently uses SMTP with no encryption. The security administrator would like to implement encryption between email clients without changing the existing server-to-server communication. Which of the following would be the BEST way to implement this requirement? ❍ A. Implement Secure IMAP ❍ B. Require the use of S/MIME ❍ C. Install an SSL certificate on the email server ❍ D. Use a VPN tunnel between email clients
The Answer: B. Require the use of S/MIME S/MIME (Secure/Multipurpose Internet Mail Extensions) provides a way to integrate public key encryption and digital signatures into most modern email clients. This would encrypt all email information from client to client, regardless of the communication used between email servers. The incorrect answers: A. Implement Secure IMAP Secure IMAP (Internet Message Access Protocol) would encrypt communication downloaded from an email server, but it would not provide any security for outgoing email messages. C. Install an SSL certificate on the email server An SSL certificate on an email server could potentially be used to encrypt server-to-server communication, but the security administrator is looking for an encryption method between email clients. D. Use a VPN tunnel between email clients Email communication does not occur directly between email clients, so configuring a VPN between all possible email recipients would not be a valid implementation.
