PS-08-004 Computer Security Incident Management

Issue Date: 3/20/2008

Review Date: 08/30/2024

PURPOSE

The number of computer security incidents and the resulting cost of business disruption and service restoration continue to escalate.  Implementing solid security policies, limiting access to networks and computers, improving user security awareness, and early detection and mitigation of security risks are some of the preventative actions that can be taken to reduce the risk, frequency, and cost of security incidents, not all incidents can be prevented.  Therefore, an incident response capability is necessary for rapidly detecting incidents, minimizing loss and destruction, mitigating the weaknesses that were exploited, and restoring computing services.

This policy establishes the requirement for each agency to establish an internal capability for handling computer security incidents.
