Which of the following is a feature of virtualization that can potentially create a single point of failure?
Correct Answer:
A
An organization is in the process of integrating its operational technology and information technology areas. As part of the integration, some of the cultural aspects it would like to see include more efficient use of resources during change windows, better protection of critical infrastructure, and the ability to respond to incidents. The following observations have been identified:
The ICS supplier has specified that any software installed will result in lack of support.
There is no documented trust boundary defined between the SCADA and corporate networks.
Operational technology staff have to manage the SCADA equipment via the engineering workstation. There is a lack of understanding of what is within the SCADA network.

Correct Answer:
A
An information security manager is concerned that connectivity used to configure and troubleshoot critical network devices could be attacked. The manager has tasked a network security engineer with meeting the following requirements:
Encrypt all traffic between the network engineer and critical devices. Segregate the different networking planes as much as possible.
Do not let access ports impact configuration tasks.
Which of the following would be the BEST recommendation for the network security engineer to present?
Correct Answer:
B

Ann, a web developer, reports performance issues with her laptop and is not able to access any network resources. After further investigation, a bootkit was discovered and it was trying to access external websites. Which of the following hardening techniques should be applied to mitigate this specific issue from reoccurring? (Select TWO).
Correct Answer:
DG
A rootkit is a collection of computer software, typically malicious, designed to enable access to a computer or areas of its software that would not otherwise be allowed (for example, to an unauthorized user) while at the same time masking its existence or the existence of other software. A bootkit is similar to a rootkit except the malware infects the master boot record on a hard disk. Malicious software such as bootkits or rootkits typically require administrative privileges to be installed.
Therefore, one method of preventing such attacks is to remove administrative access for local users. A common source of malware infections is portable USB flash drives. The flash drives are often plugged into less secure computers such as a user’s home computer and then taken to work and plugged in to a work computer. We can prevent this from happening by restricting or disabling access to USB devices.
Incorrect Answers:
A: Using a group policy to limit web access is not a practical solution. Users in a company often require Web access so restricting it will affect their ability to do their jobs.
B: Rootkits or Bootkits would not be caught by connecting to the network over a VPN so disabling VPN access will not help.
C: Removing full-disk encryption will not prevent Bootkits.
E: Bootkits are not caught by connecting to network resources using Telnet connection so disabling Telnet access to resources will not help.
F: Performing vulnerability scanning on a daily basis might help you to quickly detect Bootkits. However, vulnerability scanning does nothing to actually prevent the Bootkits.
