100 Days to STIG Policy Implementation

This guide presents a structured 100-day plan for implementing DISA Security Technical Implementation Guides (STIGs) to improve system hardening and regulatory compliance across enterprise environments. It explains how STIG controls standardize secure configurations for operating systems, databases, applications, and network devices while supporting mandates such as NIST RMF and DoD cybersecurity requirements. The roadmap covers asset discovery, role assignment, baseline assessment, remediation prioritization, automation, validation, and continuous monitoring. Emphasis is placed on reducing manual configuration effort, integrating vulnerability scanning tools, and establishing repeatable processes. By operationalizing STIG enforcement, organizations can quickly close security gaps, limit misconfigurations, and sustain audit-ready security postures with existing teams and infrastructure.
