What is the CIS AWS Foundations Benchmark?
The CIS Amazon Web Services Foundations Benchmark is the consensus security baseline for AWS accounts. Its core sections cover identity and access management (root account protection, MFA, credential and policy hygiene), logging (CloudTrail and related audit logging), monitoring (alerting on high-risk account activity), and networking (restricting inbound access in security groups and network ACLs). Each recommendation includes audit and remediation procedures, and checks are assessed agentlessly through AWS APIs because they evaluate account configuration rather than host state.
The longer answer.
The IAM section carries the most weight because account-level identity mistakes (an active root account, users without MFA, stale credentials, overly broad policies) undermine every other control in the account. Logging and monitoring come next: CloudTrail provides the audit record, and the monitoring recommendations alert on the account changes most associated with compromise.
AWS accounts drift as teams create resources, so point-in-time assessments age quickly. Continuous agentless scanning with drift detection keeps accounts verified between audits, and CISGuard maps every result to NIST 800-53, ISO 27001, and SOC 2 so one AWS scanning program produces evidence for each framework in scope.
