Develop a simple yet methodical set of response steps

• Introduction outlining the purpose and scope of the plan
• A list of security incident response team members and full contact information mentioned above
• A list of the types of incidents that will cause you to invoke the plan mentioned above
• Technologies and operations in place to detect incidents
• Specific steps for containing incidents
• Procedures for investigating what happened. (Don't overlook the value of a formal cybercrime investigation if it appears to be serious enough; otherwise, you can end up overlooking things or ruining evidence.)
• High-level steps for eliminating the threats and associated vulnerabilities (ideally one set of steps for each type of incident)
• Specific steps for following up to ensure the threats and vulnerabilities are gone (such as virus scanning, port scanning, vulnerability testing and network analysis)
• Procedures for communicating with external parties such as customers, business partners and the media (this may be one of the first things your organization is required to do!)
• Requirements for retaining records related to security breaches

In the end, make sure your plan addresses these six major areas:

1. Who does what?
2. What must be done?
3. When must it be done?
4. Where must it be done?
5. How must it be done?
6. What's done when all is said and done?
