Episode 3 - (Part 2) NIST SP 800-61 Computer Security Incident Handling Guide (Detection)

05/31/24 • 11 min

In this conclusion of the Detection phase, Clint wraps up Incident Prioritisation. This includes Functional impacts of the incident, information impact of the incident and the recoverability of the incident.
Not all of these are needed, or relevant when tracking your incident and Clint explains when to categorise incidents using these factors.
To finish off, Clint discusses incident notification - Who are the stakeholders that need to be informed and included in your incident response process, and how will they be notified?

Show Notes: Episode on Containment, Eradication, and Recovery

In this episode of Traffic Light Protocol, Clint Marsden explores the containment, eradication, and recovery phases of the NIST SP 800-61 framework for computer security incident handling.

Key Topics Covered:

Containment Strategies: Choosing appropriate containment methods based on the incident type, potential damage, service availability, and evidence preservation. Examples include power disconnection and network isolation.
Real-World Example: Clint shares an incident response case where premature action against attackers led to a total domain takeover.
Evidence Gathering and Handling: The use of tools like write blockers to preserve evidence integrity.
Threat Analysis: Highlights passive techniques for analysing threats without alerting attackers, such as remote log analysis and OPSEC to track attackers
Restoration and Recovery: Covers steps to restore systems to normal operations, including vulnerability patching, backup restoration, and password resets.
Future Considerations: Suggests engaging with external vendors for comprehensive incident response and utilizing threat intelligence platforms.
