A well-defined timeline of the events is the most important factor to ensure accurate incident response reporting, as it provides a clear and chronological account of what happened, when it happened, who was involved, and what actions were taken. A timeline helps to identify the root cause of the incident, the impact and scope of the damage, the effectiveness of the response, and the lessons learned for future improvement. A timeline also helps to communicate the incident to relevant stakeholders, such as management, legal, regulatory, or media entities. The other factors are also important for incident response reporting, but they are not as essential as a well-defined timeline. Official References:

An incident manager should work with the legal and public relations entities to ensure correct processes are adhered to when communicating incident reporting to the general public, as a best practice. The legal entity can provide guidance on the legal implications and obligations of disclosing the incident, such as compliance with data protection laws, contractual obligations, and liability issues. The public relations entity can help craft the appropriate message and tone for the public communication, as well as manage the reputation and image of the organization in the aftermath of the incident. These two entities can help the incident manager balance the need for transparency and accountability with the need for confidentiality and security12.

PID 2264 (bash running as root) is suspicious because:
It has elevated privileges (root user).
Bash (command-line shell) is running with high CPU usage (14.0%), which is unusual unless actively being used.
If unauthorized, an attacker could be exfiltrating data via command-line methods like scp, wget, or custom scripts.
Why Not Other Options?
B: (34218 - Xorg) → Xorg is a display server for GUI; no signs of exfiltration.
C: (34834 - Cinnamon) → Cinnamon is a desktop environment, not a threat.
D: (35963 - xrdp) → xrdp is a remote desktop service, expected behavior.

This is because scanning without admin privileges can limit the scope and accuracy of the vulnerability scan, and potentially miss some critical vulnerabilities that require higher privileges to detect. According to the OWASP Vulnerability Management Guide1, "scanning without administrative privileges will result in a large number of false negatives and an incomplete scan". Therefore, the analyst should recommend addressing this issue to ensure potential vulnerabilities are identified.

Audit settings provide visibility into user actions and system events. These are classified asdetective controls because they enable the detection of anomalies, policy violations, or unauthorized access by generating logs or alerts. They do not prevent actions (Preventive) or reverse harm (Corrective), nor do they provide policy guidance (Directive).
