Incident Response SANS: The 6 Steps in Depth
When a security event occurs, incident response ensures that companies are aware of it and that they can act promptly to limit the harm caused. The goal is also to avoid any more attacks or situations of a similar nature from taking place in the future.
The SANS Institute is a private organization that does information security research and educates its members. As a result of this post, we will go through in detail the six components of a SANS incident response plan, which include factors such as preparation, identification, containment, and eradication of a threat.

In this post, we will discuss:
The term “incident response” refers to the process of responding to an occurrence.

What Is Incident Response and How Does It Work?
INCIDENT RESPONSE is a process that enables organizations to identify, prioritize, contain, and eliminate cyberattacks and other security threats. Ultimately, the goal of incident response is to ensure that organizations are aware of significant security incidents and can respond quickly to stop the attacker, minimize the damage done, and prevent further attacks or similar incidents in the future.
What Is SANS?
The SANS Institute is a private organization that was founded in 1989 to conduct research and provide education in the field of information security. It is the world’s largest provider of security training and certification, and it also maintains the world’s largest collection of cybersecurity research. Aside from that, SANS runs the Internet Storm Center, which serves as an early warning system for global cyber threats.
SANS Incident Response Plan
The SANS Institute has developed a 20-page booklet that outlines an organized 6-step plan for incident response, which may be found here. The following is a high-level overview of the process, and the following parts will go into greater detail about each phase in more detail:
- Review and codify an organization’s security policy, conduct a risk assessment, identify sensitive assets, determine which security incidents are critical and should be the team’s primary focus, and form a Computer Security Incident Response Team (CSIRT).
- Identification—monitor information technology systems for deviations from normal operations and determine whether these deviations represent actual security incidents.
- When an incident is discovered, gather additional evidence, determine the type and severity of the incident, and thoroughly document the entire situation.
- Implement short-term containment measures, such as isolating the network segment that is under assault. Containment measures include: After that, concentrate on long-term containment, which entails temporary solutions to allow systems to be used in production while clean systems are being reconstructed.
- Eradication is the process of removing malware from all affected systems, identifying the root cause of the attack, and taking steps to prevent similar attacks in the future from occurring.
- Recovery—carefully bring affected production systems back online to avoid further attacks. Test, validate, and monitor the affected systems to confirm that they are operating at their usual levels.
- Performance of a retrospective of the incident should be completed no later than two weeks after the conclusion of the incident. Prepare a comprehensive record of the occurrence, do a thorough investigation into the issue, determine what was done to contain it, and determine whether anything about the incident response procedure may be improved.
