Debian GNU/Linux 13 Hardened CIS

CIS Hardened Image Debian 13 (Level 1) is a production-ready Amazon Machine Image built for organizations that need to deploy secure, compliant Linux workloads on AWS without spending weeks manually applying security controls. This image ships with the CIS Debian Linux 13 Benchmark Level 1 hardening profile already applied, covering hundreds of configuration checks across filesystem permissions, kernel parameters (sysctl), SSH hardening, auditd logging, PAM password policies, service minimization, and secure boot settings. By eliminating the manual hardening process, you reduce the risk of misconfiguration, accelerate time-to-production, and ensure every instance launches from a consistent, auditable security baseline that aligns with industry-recognized CIS Benchmarks.

Beyond baseline hardening, this AMI includes a pre-integrated security and observability stack designed for modern cloud operations. The Wazuh SIEM agent is pre-installed and ready to forward security events, file integrity monitoring (FIM) alerts, and compliance data to your central Wazuh manager, giving you real-time threat detection and host-based intrusion detection out of the box. Nagios monitoring agents provide infrastructure health visibility from the first boot, while pre-configured firewall policies enforce a least-privilege network posture by default. Together, these components deliver defense in depth, continuous compliance monitoring, and operational visibility without requiring additional tooling or manual integration work.
