SANS Incident Response Steps. Step #1: Preparation. Step #2: Identification. Step #3: Containment. Step #4: Eradication. Step #5: Recovery. Step #6: Lessons Learned. When we compare the NIST and SANS frameworks side-by-side, you'll see the components are almost identical, but differ slighting in their wording and grouping.
The primary steps in an IRP include: Preparation: Preparation is a key step in an effective response. Detection and analysis: Put security safeguards in place. Containment: Minimize the scope of the security incident. Eradication: Eliminate the root cause of the security incident.

The goal of the preparation stage is to ensure that the organization can comprehensively respond to an incident at a moment’s notice. In a SANS incident response plan, these are critical elements that should be prepared in advance: 1. Policy—define principle, rules and practices to guide security processes. Ensure the policy is highly visible both ...
This step involves detecting deviations from normal operations in the organization, understanding if a deviation represents a security incident, and determining how important the incident is. The SANS incident response identification procedure includes the following elements: 1. Setting up monitoringfor all sensitive IT systems and infrastructure. ...
The goal of containment is to limit damage from the current security incident and prevent any further damage. Several steps are necessary to completely mitigate the incident, while also preventing destruction of evidence that may be needed for prosecution. The SANS containment process involves: 1. Short-term containment—limiting damage before the i...
Eradication is intended to actually remove malware or other artifacts introduced by the attacks, and fully restore all affected systems. The SANS eradication process involves: 1. Reimaging—complete wipe and re-image of affected system hard drives to ensure any malicious content is removed. 2. Preventing the root cause—understanding what caused the ...
The goal of recovery is to bring all systems back to full operation, after verifying they are clean and the threat is removed. The SANS recovery procedure involves: 1. Defining time and date to restore operations—system owners should make the final decision on when to restore services, based on information from the CSIRT. 2. Test and verifying—ensu...
No later than two weeks from the end of the incident, the CSIRT should compile all relevant information about the incident and extract lessons that can help with future incident response activity. The SANS lessons learned process includes: 1. Completing documentation—it is never possible to document all aspects of an incident while it is going on, ...

- Preparation. This phase will be the work horse of your incident response planning, and in the end, the most crucial phase to protect your business. Part of this phase includes
- Identification. This is the process where you determine whether you’ve been breached. A breach, or incident, could originate from many different areas.
- Containment. When a breach is first discovered, your initial instinct may be to securely delete everything so you can just get rid of it. However, that will likely hurt you in the long run since you’ll be destroying valuable evidence that you need to determine where the breach started and devise a plan to prevent it from happening again.
- Eradication. Once you’ve contained the issue, you need to find and eliminate the root cause of the breach. This means all malware should be securely removed, systems should again be hardened and patched, and updates should be applied.
- Preparation. Your incident response begins long before something has gone wrong. The preparation phase is the most important step in equipping your incident response team to protect your business.
- Declaration. The goal of the incident declaration phase is to recognize and raise an issue as soon as possible and categorize it based on severity, priority, scope, type, and any other categories you've outlined in your plan.
- Resolution. Resolution is key when dealing with any type of incident, whether it's a security breach, a data leak, a software defect, or a system outage.
- Containment. After you've contained the incident, investigated it, and documented everything you need to know, the next step is closing it out.
