Security Technical Implementation Guides (STIGs) are configuration standards developed by the Defense Information Systems Agency (DISA) for Department of Defense (DoD) information systems. These guides provide:
- Technical security policies through prescriptive configuration requirements
- Standardized security settings to reduce vulnerabilities
- Compliance benchmarks for security assessments and audits
For organizations like LogN Pacific, STIG compliance is essential for:
- Meeting contractual obligations with federal agencies
- Establishing a hardened security baseline
- Reducing attack surface through proven configurations
- Demonstrating security maturity to stakeholders
In Q2 2025, LogN Pacific secured a significant contract with a federal agency requiring STIG compliance for all systems handling sensitive data. Our initial assessment revealed:
- No formal STIG compliance program in place
- Inconsistent security configurations across Windows endpoints
- Manual configuration management leading to drift
- Lack of continuous compliance monitoring
- Establish formal STIG compliance governance
- Achieve measurable security improvements
- Implement automated compliance mechanisms
- Create scalable processes for future growth
The first critical step was developing a comprehensive STIG Compliance Policy to formalize our approach and establish clear accountability. The policy development process involved:
- Stakeholder Engagement: Collaborated with IT Operations, Security, Legal, and Compliance teams
- Risk Assessment: Evaluated business impact of STIG implementations
- Process Design: Created workflows for assessment, remediation, and exception handling
- Tool Selection: Evaluated and selected Tenable.io for automated STIG scanning
Our STIG Compliance Policy addresses:
- Compliance scope and system classifications
- Assessment frequencies and remediation timelines
- Automated vs. manual remediation criteria
- Exception management procedures
- Roles and responsibilities
- Continuous improvement processes

1. Phased Implementation Approach Rather than attempting to remediate all findings simultaneously, we adopted a risk-based phased approach:
- Phase 1: Policy and process establishment
- Phase 2: Baseline assessment
- Phase 3: Pilot remediation (10 representative STIGs)
- Phase 4: Full rollout based on pilot results
2. Automation First Strategy To ensure consistency and reduce operational overhead, we prioritized automated remediation for:
- Low-risk configuration changes
- Settings with minimal user impact
- Configurations with clear rollback procedures
3. Exception Management Recognizing that some STIGs may conflict with business requirements, we established:
- Formal exception request process
- Required compensating controls
- Quarterly exception reviews
- Executive approval requirements
With our STIG Compliance Policy approved by executive leadership, LogN Pacific proceeded with a comprehensive baseline assessment of our Windows infrastructure. This initial scan would provide critical insights into our current security posture and help prioritize remediation efforts.
Scanning Configuration
- Tool: Tenable.io with DISA Windows 10 STIG benchmark
- Scope: 500 Windows 10 workstations across corporate network
- Date: June 13, 2025
- Scan Type: Authenticated compliance scan with domain administrator credentials
Pre-Scan Preparation
- Configured Tenable.io STIG audit files (DISA Microsoft Windows 10 STIG v3r4)
- Established scanning service account with appropriate permissions
- Scheduled scans during maintenance window to minimize impact
- Notified IT Operations team of scanning activities
Baseline Compliance Metrics:
- Total Checks: 262
- Failed: 152 (58%)
- Warning: 16 (6%)
- Passed: 94 (36%)
Severity Distribution of Failed Checks:
- CAT I (High Severity): 18 findings
- CAT II (Medium Severity): 89 findings
- CAT III (Low Severity): 45 findings
1. Critical Security Gaps Several high-risk configurations were identified that required immediate attention:
- WDigest authentication enabled (credential theft risk)
- Automatic logon configurations present
- Weak authentication protocols permitted
2. Common Configuration Drift Many failures resulted from inconsistent Group Policy application:
- Local policy overrides
- Systems missing from security OUs
- Manual configuration changes by administrators
3. Business Impact Considerations Initial analysis revealed potential conflicts with business operations:
- Telemetry settings required for helpdesk support
- Convenience features expected by executive users
- Legacy application compatibility concerns
Working with the Information Security team, we categorized findings by remediation priority:
Immediate Action Required (Week 1)
- Critical authentication vulnerabilities
- Remote access security gaps
- Administrative privilege exposures
Short-term Remediation (Month 1)
- Network security hardening
- Application control policies
- Audit and logging enhancements
Planned Remediation (Quarter 1)
- User experience impacting settings
- Performance-affecting configurations
- Legacy compatibility issues
Given the scale of findings and potential business impact, LogN Pacific's security leadership made a strategic decision:
Implement a Pilot Remediation Program
Rather than attempting to remediate all 152 failures simultaneously, we would:
- Select 10 representative STIGs across different risk levels
- Develop and test automated remediation scripts
- Measure impact and refine processes
- Use lessons learned for full-scale rollout
The following 10 STIGs were chosen for the pilot program based on:
- Risk severity distribution
- Technical complexity variety
- Business impact assessment
- Automation feasibility
| STIG ID | Title | Severity | Rationale |
|---|---|---|---|
| WN10-CC-000038 | WDigest Authentication | CAT I | Critical security risk |
| WN10-CC-000325 | Auto-Restart Sign-On | CAT I | High exposure risk |
| WN10-CC-000370 | Convenience PIN | CAT II | Authentication weakness |
| WN10-CC-000005 | Lock Screen Camera | CAT II | Privacy concern |
| WN10-CC-000365 | Voice Activation | CAT II | Unauthorized access |
| WN10-CC-000205 | Telemetry Settings | CAT II | Data collection |
| WN10-SO-000185 | PKU2U Authentication | CAT II | Protocol vulnerability |
| WN10-CC-000170 | Microsoft Accounts | CAT II | Account control |
| WN10-CC-000197 | Consumer Features | CAT III | Enterprise standards |
| WN10-SO-000080 | Legal Notice | CAT III | Compliance requirement |
Before proceeding with the pilot, we established clear success metrics:
- Technical: 100% successful remediation of pilot STIGs
- Operational: Zero production incidents related to changes
- Performance: No measurable system performance impact
- User Impact: Less than 5 helpdesk tickets generated
With baseline assessment complete and pilot STIGs identified, LogN Pacific was ready to move forward with automated remediation development and testing. The pilot program would serve as a proof of concept for enterprise-wide STIG compliance.
Following approval from LogN Pacific's Change Advisory Board, we initiated our pilot remediation program on June 20, 2025. The pilot was designed to validate our automated approach while minimizing risk to production systems.
Phased Rollout
- Week 1: Development environment (50 systems)

Remediation Scripts Individual PowerShell scripts were developed for each of the 10 pilot STIGs, incorporating:
- Pre-change validation checks
- Detailed logging mechanisms
- Automated rollback capabilities
- Post-implementation verification
Individual PowerShell remediation scripts were developed for each pilot STIG. Each script includes validation checks, logging, and rollback capabilities.
