Question 3

Which of the following activities is best suited for the 'Recovery' phase of the incident handling process?

Accepted Answer

Scanning for vulnerabilities to ensure the exploit vector is closed. The Recovery phase of incident handling focuses on restoring normal operations and ensuring the exploited vulnerability is remediated to prevent re-infection. Scanning for vulnerabilities to confirm the exploit vector is closed is a recovery activity that validates the system is safe to return to production. This aligns with the goal of returning to a secure state after containment and eradication.

Answer

Isolating infected hosts from the network

Answer

Interviewing employees about the incident

Answer

Notifying the media of the breach

Question 4

You are configuring an automated incident response workflow in TheHive. Which specific configuration parameter must be validated to ensure that the incident triage phase correctly captures the 'Impact' and 'Urgency' fields for reporting?

Accepted Answer

The 'Custom Fields' definition within the incident template configuration. In TheHive, these fields are part of the incident template configuration, and incorrect mapping leads to failed data normalization during the ingestion phase.

Answer

The 'Elasticsearch' index prefix in system settings

Answer

The 'Analyzer' timeout setting in the application.conf file

Answer

The 'Cortex' connection string in the GUI settings

Question 5

During a ransomware outbreak, the incident response team lead must decide whether to disconnect a critically infected file server from the network. The server hosts a database that a revenue-generating application depends on. The team has already collected volatile data and a forensic image. Which containment approach best balances incident impact with business continuity?

Accepted Answer

Isolate the server from the network while keeping it powered on and allowing the database to continue serving the application locally.. The best containment strategy isolates the affected system to prevent further spread while maintaining essential business functions. Keeping the server powered on preserves volatile evidence and allows the database to continue serving the application locally. This approach aligns with the incident handling process by balancing damage limitation with operational continuity. It also avoids destructive actions like powering off or reimaging, which could complicate recovery and evidence collection.

Answer

Reimage the server immediately to restore operations, then reconnect it to the network.

Answer

Immediately power off the server to stop the encryption process.

Answer

Leave the server connected to monitor the attacker's behavior and gather more intelligence.

Question 6

A financial services firm has just confirmed a ransomware infection on several endpoints. The incident response team is preparing to contain the incident while preserving the ability to investigate and recover. Which TWO of the following containment actions are MOST appropriate at this stage? (Choose two.)

Accepted Answer

Disconnect the affected endpoints from the network to prevent further spread.. Containment aims to stop the spread of ransomware while preserving evidence and enabling recovery. Isolating infected endpoints and isolating the affected network segment both limit lateral movement and protect critical assets. Recovery actions such as reimaging or restoring backups must wait until containment is complete and the root cause is understood.

Answer

Disable the compromised user accounts and reset their credentials.

Answer

Reimage all affected endpoints immediately to restore normal operations.

Answer

Restore affected systems from the most recent backups.
