Enterprise Linux Security Challenges

Linux systems form the backbone of modern enterprise infrastructure, from web servers to container orchestration platforms. However, default configurations often prioritize functionality over security, leaving organizations vulnerable to sophisticated attacks. Proper Linux hardening and compliance management is essential for protecting critical business assets.

Common Linux Security Risks

  • Insecure default configurations
  • Privilege escalation vulnerabilities
  • Unprotected network services
  • Weak authentication mechanisms
  • Unpatched system vulnerabilities
  • Insufficient logging and monitoring

Compliance Standards We Address

  • CIS Benchmarks (Level 1 & 2)
  • DISA STIG (Security Technical Implementation Guides)
  • NIST 800-53 Security Controls
  • HITRUST CSF Requirements
  • SOC 2 Type II Controls
  • Internal Security Policies
