  • Only when the incident first occurs
  • Only prior to the incident occurring
  • At least one month after the incident is over

In the event of a security incident, it is appropriate to refer to an incident response playbook throughout the entire incident. An incident response playbook is a guide with six phases used to help mitigate and manage security incidents from beginning to end.

2. Fill in the blank: During the _____ phase, security professionals use tools and strategies to determine whether a breach has occurred and to evaluate its potential magnitude.

  • preparation
  • detection and analysis (CORRECT)
  • containment

During the detection and analysis phase, security professionals use tools and strategies to determine whether a breach has occurred and to evaluate its potential magnitude.

3. In which incident response playbook phase would a security team document an incident to ensure that their organization is better prepared to handle future security events?

  • Eradication and Recovery
  • Coordination
  • Containment

In the post-incident activity phase, a security team documents an incident to ensure that their organization is better prepared to handle future incidents. Containment involves preventing further damage and reducing the immediate impact of a security incident.

4. What is the relationship between SIEM tools and playbooks?

  • Playbooks detect threats and generate alerts, then SIEM tools provide the security team with a proven strategy.
  • They work together to provide a structured and efficient way of responding to security incidents. (CORRECT)
  • Playbooks collect and analyze data, then SIEM tools guide the response process.
  • They work together to predict future threats and eliminate the need for human intervention.

SIEM tools and playbooks work together to provide a structured and efficient way of responding to security incidents.

5. Which statements are true about playbooks? Select three answers.

  • Playbooks ensure that people follow a consistent list of actions in a prescribed way. (CORRECT)
  • Playbooks categorize and analyze large amounts of data to help security teams identify risk.
  • Playbooks are manuals that provide details about any operational action. (CORRECT)
  • Playbooks are manuals that provide details about any operational action, clarify what tools should be used, and ensure people follow a consistent list of actions to address security incidents.
  • Playbooks clarify what tools should be used to respond to security incidents.(CORRECT)

Playbooks are manuals that provide details about any operational action, clarify what tools should be used, and ensure people follow a consistent list of actions to address security incidents.

TEST YOUR KNOWLEDGE: USE A PLAYBOOK TO RESPOND TO AN INCIDENT

1. Playbooks are permanent, best-practice documents, so a security team should not make changes to them.

  • True
  • False (CORRECT)

Playbooks are living documents, so a security team will make frequent changes, updates, and improvements to address new threats and vulnerabilities.

2. A business recently experienced a security breach. Security professionals are currently restoring the affected data using a clean backup that was created before the incident. What playbook phase does this scenario describe?

  • Containment
  • Eradication and recovery (CORRECT)
  • Post-incident activity
  • Detection and analysis

This scenario describes eradication and recovery. This phase involves removing the incident’s artifacts and restoring the affected environment to a secure state.

3. Fill in the blank: Once a security incident is resolved, security analysts perform various post-incident activities and _____ efforts with the security team.

  • eradication
  • detection
  • coordination (CORRECT)
  • preparation

Once a security incident is resolved, security analysts perform various post-incident activities and coordination efforts with the security team. Coordination involves reporting incidents and sharing information based on established standards.

4. Which action can a security analyst take when they are assessing a SIEM alert?

  • Analyze log data and related metrics (CORRECT)
  • Isolate an infected network system
  • Restore the affected data with a clean backup
  • Create a final report

An action that a security analyst can take when they are assessing a SIEM alert is to analyze log data and related metrics. This helps in identifying why the alert was generated by the SIEM tool and determining if the alert is valid.
