Incident Response (IR) Controls

The Incident Response (IR) family of controls is designed to ensure that organizations have the capabilities, processes, and tools to effectively detect, respond to, and recover from security incidents. These controls are critical for maintaining the confidentiality, integrity, and availability of data when an incident occurs. IR-1: Incident Response Policy and Procedures Control Overview IR-1 requires organizations to establish and maintain incident response policies and procedures that clearly define the approach to handling security incidents. These policies must cover everything from identifying incidents to post-incident reporting. Example: A cloud provider works with a federal agency to create an incident response policy that includes detailed steps for identifying and reporting incidents, escalating issues, and ensuring timely recovery.

The Security Assessment (SA) family of controls, derived from NIST 800-53 Revision 5, plays a pivotal role in keeping systems secure over time. What Are the Security Assessment (SA) Controls? The SA family of controls focuses on ensuring that security controls are assessed for their effectiveness and are continuously monitored throughout the life of the system. This means checking whether the security measures in place are not only effective but remain effective and up-to-date as time progresses. For FedRAMP Moderate, these controls are crucial because: They ensure security controls are evaluated regularly. They support continuous monitoring for vulnerabilities or weaknesses. They establish corrective actions when necessary. SA-1: Security Assessment and Authorization Policies and Procedures Control Overview SA-1 requires the development of security assessment and authorization (A&A) policies and procedures. These procedures outline the process for conducting security assessm...
