Mitigating Risk with a Computer Incident Response Team Plan |
CHAPTER |
COMPUTER SECURITY incidents can result in the loss of confidentiality, integrity, or availability of data or services. Attackers will attack, and incidents will happen. However, an organization can be prepared with computer incident response teams (CIRTs). These teams are trained and have the knowledge and expertise to reduce the damage resulting from attacks. Their actions are guided by a CIRT plan.
The primary purpose of a CIRT plan is to help an organization prepare for incidents and mitigate the damage. The plan identifies members based on their roles and responsibilities. It includes policy statements related to incidents, such as whether CIRT members are authorized to attack back, and detailed information on how to handle incidents.
Chapter 15 Topics
This chapter covers the following topics and concepts:
- What a computer incident response team (CIRT) plan is
- What the purpose of a CIRT plan is
- What the elements of a CIRT plan are
- How a CIRT plan can mitigate an organization’s risk
- What best practices for implementing a CIRT plan are
Chapter 15 Goals
When you complete this chapter, you will be able to:
- Define a CIRT
- Define a CIRT plan
- Describe the roles and responsibilities of CIRT members
- Describe CIRT policies
- Define a computer incident
- Describe the incident handling process
- Describe communication escalation procedures
- Describe incident handling procedures
- Describe how a CIRT plan can mitigate an organization’s risk
- List best practices for implementing a CIRT plan for an organization
