When dealing with a 10BASE5 network, which of the following is the MOST likely security risk?
-
An incorrect VLAN
-
SSID broadcasting
-
A repeater
-
A vampire tap
Correct Answer
A. A vampire tapExplanation
10BASE5 network uses coaxial wire (similar to cable co. wire)as the infrastructure. Although this configuration is mostly phased out in networks, the primary security risk was the use of Vampire Taps. These taps are named based on their physical design, which resembles how a vampire would bite into a wire - using two teeth of different sizes. One taps the braided outer shielding while another longer prong taps the center conductor. Once in place, all data on the net can be stolen with no indication the device is in place.

A flat or simple role-based access control (RBAC) embodies which of the following principles?
-
Users assigned to roles, permissions are assigned to groups, controls applied to groups and permissions acquired by controls
-
Users assigned permissions, roles assigned to groups and users acquire additional permissions by being a member of a group
-
Roles applied to groups, users assigned to groups and users acquire permissions by being a member of the group
-
Users assigned to roles, permissions are assigned to roles and users acquire permissions by being a member of the role
Correct Answer
A. Users assigned to roles, permissions are assigned to roles and users acquire permissions by being a member of the roleExplanation
In a flat or simple role-based access control (RBAC), users are assigned to roles. Permissions are then assigned to roles, and users acquire those permissions by being a member of the role. This means that instead of directly assigning permissions to users or groups, permissions are assigned to roles, and users gain those permissions by being assigned to the corresponding roles. This approach simplifies access control management by centralizing permissions at the role level and allowing for easier assignment and revocation of permissions based on user roles.Rate this question:

After determining which patches are needed and applying them, the next step in patch management is to audit for the successful application of the patches. This involves verifying that the patches were installed correctly and have effectively resolved the vulnerabilities they were intended to address. This auditing process ensures that the system is secure and protected against potential threats.Rate this question:

In which of the following situations would it be appropriate to install a hotfix?
-
A patch in a service pack fixes the issue, but too many extra patches are included.
-
A patch is not available and workarounds do not correct the problem.
-
A patch is available, but has not yet been tested in a production environment
-
A patch is too large to be distributed via a remote deployment tool
Correct Answer
A. A patch is not available and workarounds do not correct the problem.Explanation
If a patch is not available and workarounds do not correct the problem, it would be appropriate to install a hotfix. A hotfix is a software update specifically designed to address a particular issue or bug that is causing problems. In this situation, since there is no patch available and the workarounds are not effective, installing a hotfix would be the best course of action to resolve the problem.Rate this question:

-
Vulnerability assessment
-
Fingerprinting
-
Penetration testing
-
Fuzzing
Correct Answer
A. Penetration testingExplanation
Social engineering, password cracking, and vulnerability exploitation are all techniques used in penetration testing. Penetration testing involves simulating real-world attacks on a system or network to identify vulnerabilities and weaknesses. By using these techniques, a penetration tester can assess the security posture of the target and provide recommendations for improvement.Rate this question:

If an administrator does not have a NIDS examining network traffic, which of the following could be used to identify an active attack?
-
Protocol analyzer
-
Penetration testing tool
-
Network mapper
-
Vulnerability scanner
Correct Answer
A. Protocol analyzerExplanation
A protocol analyzer can be used to identify an active attack if an administrator does not have a NIDS examining network traffic. A protocol analyzer is a tool that captures and analyzes network traffic, allowing the administrator to inspect packets and detect any suspicious or malicious activity. By analyzing the network traffic, the administrator can identify any unusual patterns or behaviors that may indicate an active attack. Therefore, a protocol analyzer can be a useful tool in detecting and investigating potential security breaches in the absence of a NIDS.Rate this question:

Configuration baselines should be taken at which of the following stages in the deployment of anew system?
-
Before initial configuration
-
Before loading the OS
-
After a user logs in
-
After initial configuration
Correct Answer
A. After initial configurationExplanation
Configuration baselines should be taken after the initial configuration of a new system. This is because the initial configuration involves setting up the system with the necessary hardware, software, and settings. Once this initial configuration is complete, taking a configuration baseline helps establish a reference point for the system's configuration. It allows for future comparisons to identify any changes or deviations from the established baseline. Taking the baseline after the initial configuration ensures that the system is in a stable and functional state before capturing its configuration.Rate this question:

Which of the following practices should be implemented to harden workstations and servers?
-
Log on only as the administrator
-
Install only needed software
-
Check the logs regularly
-
Report all security incidents
Correct Answer
A. Install only needed softwareExplanation
Installing only needed software is a recommended practice to harden workstations and servers. By installing only necessary software, the attack surface is reduced, minimizing the potential vulnerabilities that can be exploited by malicious actors. Unnecessary software increases the risk of security breaches as it may contain vulnerabilities or provide additional avenues for attackers to gain unauthorized access. Therefore, installing only needed software helps to enhance the security posture of workstations and servers.Rate this question:

Which of the following is a mechanism that prevents electromagnetic emanations from beingcaptured?
-
Install a repeater
-
Uninterruptible power supply (UPS)
-
Faraday cage
-
Disable SSID broadcast
Correct Answer
A. Faraday cageExplanation
A Faraday cage is a mechanism that prevents electromagnetic emanations from being captured. It is a sealed enclosure made of conductive material, such as metal, that blocks external electromagnetic fields. The conductive material absorbs and redistributes the electromagnetic energy, preventing it from escaping or entering the cage. This helps to protect sensitive electronic devices from electromagnetic interference and prevents unauthorized access to electromagnetic signals.Rate this question:
