IR-05.1: Automated remediation is available and in use for certain incidents and environments

IR-05.1: Certain clear incidents are consistently and automatically remediated to reduce responder overhead. For example, if port 22 is exposed to the internet, and not blocked with a preventive control, it is autoremediated. For maturity Level 5, this capability must be consistently available at scale, managed centrally, support different rules for different environments (e.g., dev vs. prod), provide feedback to the deployment owner/team, and support approved exemptions.

Control automation: Either
AWS control specification: Config Rules for security are deployed and perform remediations
Azure control specification: none
GCP control specification: none
Third-party (CSPM/CNAPP) control specification: Pass if the CSPM/CNAPP tool includes this capability and at least three automations are enabled

Not Applicable - Not applicable

Level 1: Initial - Initial. Manually managing policies/procedures, mostly through console. Architectures tend to resemble traditional infrastructure (e.g., low use of serverless and high reliance on network security controls). IAM mostly ad hoc with little-to-no federation.

Level 2: Repeatable - Repeatable. Policy-/checklist-based and relies more on manual or simple tooling. High variability between projects; not coordinated across deployments. Initial use of infrastructure as code (Terraform/CloudFormation), but security not consistently engaged in design/review. Federation on some accounts, but limited use of MFA due to difficulties supporting teams (especially on the command line).

Level 3: Defined - Defined. Policies and central coordination in place. Some initial security automation still executed manually. Some third-party tooling (orchestration with other tools), Federation on most accounts with widespread MFA, but still gaps on consistency. Security starting to review and promote use of CloudFormation/Terraform. CSPM/CNAPP (CSP or third party) in use.

Level 4: Capable - Capable. Strong centralized security management with consistent enforcement. Automation and guardrails across multiple deployments. Expanding library. Big shift from manual management and execution to running security operations with centralized platforms with centralized management and reporting. Consistent use of federation and MFA, with some gaps supporting toolchains.

Level 5: Efficient - Efficient. All major activities centrally managed, covering all of the CSMM domains. Integrated into infrastructure-as-code (IaC) environment. Built into the stack with provisioning automation. Federation and MFA working consistently across toolchains (e.g., command-line support).
