Review Questions

• How do system logs contribute to effective malware analysis techniques?
  • System logs play a crucial role in malware analysis by providing detailed records of activities that occurred on a system during an infection. They can reveal information about when and how malware was executed, what files were accessed, and any changes made to the system. This information helps analysts understand the behavior of the malware, its impact on the system, and can guide efforts to remediate the infection.
• In what ways can the analysis of system logs assist in evidence collection during cybersecurity investigations?
  • The analysis of system logs is vital for evidence collection in cybersecurity investigations as it provides a chronological record of events that may be relevant to a security incident. Logs can help establish timelines, identify unauthorized access attempts, and uncover data exfiltration activities. By correlating log data from various sources, investigators can build a comprehensive picture of an attack or breach.
• Evaluate the importance of implementing effective log management practices in maintaining cybersecurity within an organization.
  • Implementing effective log management practices is essential for maintaining cybersecurity within an organization as it ensures that critical log data is collected, stored securely, and analyzed regularly.
