CISA QUESTION #6846
Question 1
An IS auditor discovers that security logs are generated but retained for only 7 days due to storage limitations. The organization's incident response procedures require 90 days of log data for investigation. What is the PRIMARY risk?
  • Inadequate storage capacity
  • Insufficient log retention prevents effective incident investigation and forensic analysis✔️
  • Excessive log volume
  • Complex log management
Correct Answer Explanation
The 83-day gap between log retention (7 days) and investigative requirements (90 days) means most incidents cannot be properly investigated. By the time incidents are detected and investigation begins, critical evidence has been deleted. This severely compromises security monitoring, incident response, and forensic capabilities.
