Incident handling is a crucial process that helps organizations get ready for, find, and deal with harmful events. While it’s great for IT security issues, its steps don’t match exactly with the cyber kill chain stages. This means it works well but needs careful handling for different types of cyber threats.
NIST's Four Stages Explained:
NIST, a U.S. government agency, outlines four main stages for incident handling. They created the NIST Cybersecurity Framework to help all kinds of businesses manage their cybersecurity risks better and protect their networks and data.
When dealing with incidents, focus on preparing well and detecting and analyzing what's happening. Remember, incident handling isn’t a straight path; it’s more like a circle, always improving based on new information.
Key Steps in Incident Handling:
In incident handling, there are two main tasks: investigating and recovering. Investigation means figuring out what happened, who got affected first, what tools the attacker used, and documenting everything.
Recovery involves making a plan to get things back to normal after an incident, making sure the business can keep running smoothly. Finally, incident handling wraps up with a report on what happened, how much it cost, and what can be done to prevent it from happening again.
Summary:
- Incident handling is essential for IT security readiness, though it doesn't match the cyber kill chain perfectly.
- Incident handling is cyclical, improving with each cycle based on new data.
- Core activities include investigation, recovery planning, and learning from incidents to prevent future occurrences.
