Containment, Eradication, and Recovery

Which one of the phases of incident response involves primarily active undertakings designed to limit the damage that an attacker might cause?

• Containment, Eradication, and Recovery

• Preparation

• Postincident Activity

• Detection and Analysis

Which one of the following criteria is not normally used when evaluating the appropriateness of a cybersecurity incident containment strategy?

• Effectiveness of the strategy

• Evidence preservation requirements

• Log records generated by the strategy

• Cost of the strategy

Alice is responding to a cybersecurity incident and notices a system that she suspects is compromised. She places this system on a quarantine VLAN with limited access to other networked systems. What containment strategy is Alice pursuing?

• Eradication

• Isolation

• Segmentation

• Removal

Alice confers with other team members and decides that even allowing limited access to other systems is an unacceptable risk and decides instead to prevent the quarantine VLAN from accessing any other systems by putting firewall rules in place that limit access to other enterprise systems. The attacker can still control the system to allow Alice to continue monitoring the incident. What strategy is she now pursuing?

• Eradication

• Isolation

• Segmentation

• Removal

Which one of the following tools may be used to isolate an attacker so that they may not cause damage to production systems but may still be observed by cybersecurity analysts?

• Sandbox

• Playpen

• IDS

• DLP

Tamara is a cybersecurity analyst for a private business that is suffering a security breach. She believes the attackers have compromised a database containing sensitive information. Which one of the following activities should be Tamara's first priority?

• Identifying the source of the attack

• Eradication

• Containment

• Recovery

Which one of the following activities does CompTIA classify as part of the recovery validation effort?

• Rebuilding systems

• Sanitization

• Secure disposal

• Scanning

Which one of the following pieces of information is most critical to conducting a solid incident recovery effort?

• Identity of the attacker

• Time of the attack

• Root cause of the attack

• Attacks on other organizations

Lynda is disposing of a drive containing sensitive information that was collected during the response to a cybersecurity incident. The information is categorized as a high security risk and she wishes to reuse the media during a future incident. What is the appropriate disposition for this information?

• Clear

• Erase

• Purge

• Destroy

Which one of the following activities is not normally conducted during the recovery validation phase?

• Verify the permissions assigned to each account

• Implement new firewall rules

• Conduct vulnerability scans

• Verify logging is functioning properly
