Hardened Ubuntu 26.04 LTS — Advanced Secured Server

This Azure virtual machine comes pre-configured with the latest Ubuntu 26.04 LTS (Resolute Raccoon) image, hardened to advanced security standards. Designed for organizations with elevated compliance requirements, this image goes beyond foundational controls to deliver a comprehensive security posture suited for sensitive workloads.

Built on Linux kernel 7.0 with 5-year LTS support through 2031, this image combines the latest Ubuntu platform capabilities with a multi-layered hardening approach that addresses access control, network security, audit logging, system integrity, and more.

• Linux Kernel 7.0: Latest performance improvements, hardware support, and security enhancements.
• Advanced Multi-Layer Hardening: Comprehensive controls across access management, network security, kernel parameters, service minimization, audit logging, and file integrity — beyond foundational baseline.
• Full Audit Trail: Extensive auditd rule set capturing time changes, user/group modifications, privilege escalation, file access, network changes, kernel module loads, and more.
• Kernel Module Restrictions: Unused and potentially dangerous kernel modules disabled to reduce attack surface.
• Framework Alignment: Maps to NIST CSF, ISO 27001, PCI DSS, HIPAA, DISA STIG, and other established security frameworks.
• AppArmor Enforced: Mandatory access control profiles enforced for all applicable system services.
• 5-Year LTS Support: Supported through 2031, extendable to 10 years with Ubuntu Pro.
