Free SSCA Incident Response & Recovery Questions and Answers — Questions and Answers
Question 1: What is the first step in the incident response lifecycle?
- Containment
- Recovery
- Eradication
- Preparation (Correct answer)
Correct answer: Preparation
The incident response lifecycle typically begins with the Preparation phase. This involves establishing policies, developing plans, training staff, and implementing security controls *before* an incident occurs. Effective preparation is crucial for an organization to respond quickly and effectively when an actual incident takes place, minimizing its impact.
Question 2: Which phase involves stopping an active threat and preventing further damage?
- Detection
- Containment (Correct answer)
- Reporting
- Documentation
Correct answer: Containment
The containment phase of incident response focuses on stopping the active threat and preventing it from causing further damage or spreading to other systems. This often involves isolating affected systems, disconnecting networks, or disabling compromised accounts. Effective containment is critical to limit the scope and impact of a security incident.
Question 3: Why is evidence preservation important during an incident?
- To improve software performance
- To assist in future audits
- To support forensic analysis and legal procedures (Correct answer)
- To notify customers
Correct answer: To support forensic analysis and legal procedures
Evidence preservation is critically important during an incident to maintain the integrity and chain of custody of any data or artifacts related to the breach. This preserved evidence is essential for conducting thorough forensic analysis to understand how the incident occurred, what was affected, and who was responsible. It also provides crucial support for potential legal actions or compliance audits.
Question 4: What is the primary goal of the recovery phase in incident response?
- Install new antivirus
- Restore operations and validate fixes (Correct answer)
- Delete logs
- Isolate unaffected systems
Correct answer: Restore operations and validate fixes
The primary goal of the recovery phase in incident response is to bring affected systems and services back to normal, secure operation. This involves restoring data from backups, rebuilding compromised systems, and validating that all fixes are effective and the threat has been completely eradicated. The aim is to minimize downtime and ensure business continuity.
Question 5: What tool is typically used to document the timeline and actions taken during an incident?
- System restore
- Incident response log (Correct answer)
- Antivirus scan
- Performance monitor
Correct answer: Incident response log
An incident response log is a critical tool used to meticulously document every step, decision, and action taken during a cybersecurity incident. It records the timeline of events, who did what, when, and the observed outcomes. This detailed log is invaluable for post-incident review, forensic analysis, compliance reporting, and improving future incident response procedures.
Question 6: Which of the following is a key activity during post-incident review?
- Eradicate malware
- Conduct root cause analysis (Correct answer)
- Change all user accounts
- Disconnect the internet
Correct answer: Conduct root cause analysis
A key activity during the post-incident review phase is conducting a thorough root cause analysis. This involves investigating beyond the immediate symptoms to identify the underlying factors that allowed the incident to occur. Understanding the root cause helps organizations implement permanent preventative measures and improve their overall security posture, preventing similar incidents in the future.
Question 7: What is one benefit of using incident response playbooks?
- Reduce staffing costs
- Improve consistency in handling incidents (Correct answer)
- Block all incoming traffic
- Automate marketing processes
Correct answer: Improve consistency in handling incidents
Incident response playbooks provide predefined, step-by-step instructions for handling specific types of security incidents. By following these playbooks, security teams can ensure a consistent, efficient, and effective response every time. This reduces human error, speeds up resolution, and ensures adherence to organizational policies and best practices.
Question 8: Who should be informed first when a critical incident is detected?
- Legal team
- Marketing department
- Incident response team (Correct answer)
- General public
Correct answer: Incident response team
When a critical incident is detected, the incident response team should be informed first. This team is specifically trained and equipped to handle security breaches, initiate the incident response plan, and coordinate all necessary actions. Prompt notification to the IR team ensures a rapid and organized response, minimizing potential damage and impact.
Question 9: What is an example of a recovery control after a data breach?
- Reviewing job descriptions
- Shredding paper files
- Changing user passwords (Correct answer)
- Rebooting systems
Correct answer: Changing user passwords
After a data breach, changing user passwords is a critical recovery control because it immediately invalidates any compromised credentials that attackers might have obtained. This action prevents unauthorized access to accounts and systems using the stolen passwords, thereby limiting further damage and re-establishing security. It's a direct measure to regain control and protect user data post-incident.
