PKI Trust Auditor
Security Policy for PKI Trust Auditor
Overview
This document outlines the security policy, vulnerability management procedures, and security considerations for the PKI Trust Auditor application. As a security auditing tool that handles sensitive PKI infrastructure data, maintaining robust security practices is paramount.

Security Considerations for PKI Trust Auditor
Data Security
Credential Handling
- PKI Trust Auditor uses current user credentials for all operations
- No credential storage or caching occurs within the application
- All authentication relies on Windows integrated authentication
- Users should employ dedicated service accounts with minimal required privileges
Evidence Storage
- Audit results are stored locally in the
Audit-Results/directory - Evidence files contain security assessment data and should be protected
- Downloaded certificates and CRLs are stored for analysis purposes
- No sensitive data is transmitted externally by the application
Certificate Handling
- CA certificates are retrieved from Active Directory for analysis
- AIA certificates are downloaded from configured URLs for validation
- CRL files are downloaded for accessibility testing
- All downloaded cryptographic materials should be treated as sensitive
Network Security
Communication Protocols
- WMI: Uses DCOM/RPC over port 135 (ensure proper firewall configuration)
- PowerShell Remoting: Uses WinRM over ports 5985/5986
- LDAP: Active Directory queries over port 389/636
- HTTP/HTTPS: URL reachability testing for AIA and CDP endpoints
Security Recommendations
- Implement network segmentation for CA servers
- Use encrypted channels where available (LDAPS, WinRM HTTPS)
- Configure appropriate firewall rules for required ports
- Monitor network traffic for suspicious activity
Application Security
Input Validation
- All CA configuration parameters are validated before execution
- Certificate data is parsed with proper error handling
- Template configurations are analyzed with security controls
- Registry queries include proper sanitization and validation
Error Handling
- Errors are logged without exposing sensitive information
- Stack traces are captured for debugging but not exposed to users
- Failed operations are gracefully handled with appropriate status codes
- Evidence files contain detailed execution information for troubleshooting
Dependency Security
- Regular security scanning of third-party dependencies
- Prompt application of security patches for .NET framework
- Monitoring of security advisories for System.DirectoryServices and System.Management
- Secure coding practices for all custom PowerShell scripts
Vulnerability Management Process
Vulnerability Assessment
Severity Classification
- Critical: Remote code execution, privilege escalation, data exposure
- High: Information disclosure, denial of service, authentication bypass
- Medium: Security configuration issues, improper access controls
- Low: Informational disclosures, minor security observations
Assessment Criteria
- Impact on PKI infrastructure security
- Potential for credential or certificate exposure
- Risk to audit integrity and evidence collection
- Compliance implications for security assessments
Remediation Procedures
Patch Development
- Security patches are developed in isolated branches
- Comprehensive testing against multiple PKI environments
- Backward compatibility assessment for existing audit results
- Security review before release
Release Process
- Security updates are released as patch versions (e.g., 1.0.1)
- Release notes include detailed vulnerability information
- Users are notified through multiple channels
- Critical updates may include expedited release procedures
Disclosure Policy
Coordinated Disclosure
- Vulnerabilities are disclosed after patches are available
- Credit is provided to security researchers who follow responsible disclosure
- Public disclosure includes sufficient information for users to assess risk
- No zero-day vulnerabilities are disclosed without available mitigation
Communication Channels
- GitHub Security Advisories for technical details
- Email notifications to registered users
- Website announcements for critical security updates
- Social media for broad awareness
Security Best Practices for Users
Deployment Security
Installation Guidelines
- Deploy PKI Trust Auditor on dedicated audit servers
- Use dedicated service accounts with minimal required privileges
- Implement proper access controls on audit result directories
- Regularly update to the latest secure version
Configuration Security
- Secure
parameters.jsonconfiguration files - Use domain-specific service accounts for CA access
- Implement proper logging and monitoring
- Regular security reviews of audit configurations
Access Control
Principle of Least Privilege
- Grant only necessary permissions for CA administration
- Limit network access to required ports and protocols
- Implement proper segregation of duties
- Regular access reviews for audit accounts
Monitoring and Auditing
