CIS Linux Baseline Assessment (SCAP-based)

A structured, evidence-based CIS Benchmark assessment for Linux servers using standardized SCAP methodology.

PrimeNexus delivers independent Linux baseline assessments aligned to CIS Benchmarks using OpenSCAP and SCAP Security Guide (SSG). The engagement is designed to provide audit-defensible reporting and actionable risk visibility without impacting production systems.

Service Scope

Systems Covered

  • Up to 20 Linux servers per engagement

Benchmark Coverage

  • 1 CIS Linux Benchmark – Level 1 profile

Supported Platforms

  • Oracle Linux 7 / 8 / 9
  • RHEL 7 / 8 / 9
  • Rocky Linux
  • AlmaLinux
  • Ubuntu 20.04 / 22.04

Assessment Method

  • SCAP-based automated evaluation using OpenSCAP and SSG
  • Manual validation of material findings
  • Control-level evidence capture

Methodology

The assessment follows a structured, repeatable workflow:

  1. Scope confirmation (OS versions, system count, benchmark selection)
  2. SCAP profile execution in read-only mode
  3. Collection of technical artifacts and command outputs
  4. Validation of findings against benchmark requirements
  5. Consolidated risk analysis and reporting

The assessment does not modify system configuration.

No agents are installed.
No production downtime is required.
No performance degradation is introduced.

Deliverables

Each engagement includes:

  • Executive summary with overall compliance posture
  • System-wise compliance scorecard
  • Detailed control-level findings mapped to CIS Benchmark sections
  • Risk classification (High / Medium / Low)
  • Evidence references for audit purposes
  • Prioritized remediation roadmap (high-level guidance)

Reports are structured for use in:

  • Internal security reviews
  • Customer security questionnaires
  • External audit preparation
  • Compliance evidence documentation
