SECURITY MONITORING ADDENDUM Version 1.0, January 2026 https://licenses.codesolutionsllc.com/apache-2.0-security/ SUPPLEMENTARY TERMS AND CONDITIONS FOR SECURITY MONITORING This Security Monitoring Addendum ("Addendum") supplements the Apache License, Version 2.0 ("Base License") for software that implements security monitoring and compliance verification features. By using software licensed under this Addendum, you agree to these additional terms in addition to the Base License. 1. Definitions. "Security Monitoring" shall mean automated systems that verify compliance with security policies, detect unauthorized modifications, and log security-relevant events. "Security Bypass" shall mean any attempt to circumvent, disable, or interfere with Security Monitoring components or their functions. "Bypass Code" shall mean structured identifiers (SB-xxx format) used to categorize detected Security Bypass attempts. "License Status" shall mean the verification state of the software license, which can be VALID, INVALID, or UNKNOWN. "Access Status" shall mean the operational state of the software, which can be ACTIVE or RESTRICTED based on security verification. "Compliance Controls" shall mean security requirements based on NIST SP 800-53 or equivalent security frameworks. 2. Security Monitoring Consent. By using the Work, You consent to Security Monitoring that includes: (a) Automated verification of security configurations; (b) Detection and logging of Security Bypass attempts; (c) Verification of VM hardening and network isolation; (d) Audit logging of security-relevant events; (e) License Status and Access Status verification. Security Monitoring data is stored locally and is not transmitted externally without Your explicit configuration. 3. Security Bypass Detection. The Work monitors for Security Bypass attempts using Bypass Codes: SB-001-099: Network isolation bypass attempts SB-101-199: Privilege escalation attempts SB-201-299: Hardening configuration bypasses SB-301-399: Platform-specific security violations SB-401-499: Audit system tampering attempts SB-501-599: License verification bypasses SB-901-999: Critical security violations Detection of certain Bypass Codes may result in License Status changes as described in Section 4. 4. License Status Conditions. Your License Status is determined by security verification: (a) VALID: All security verification checks pass. Full access to all features is granted. (b) INVALID: One or more critical security checks have failed. This may occur when: - Critical Security Bypass detected (SB-9xx codes) - Required security components are disabled or missing - Persistent non-compliance with Compliance Controls - VM hardening requirements are not met (c) UNKNOWN: License Status could not be determined. This typically indicates a configuration or connectivity issue. 5. Access Status Conditions. Access to the Work is controlled based on License Status: (a) ACTIVE: Full access to all features when License Status is VALID. (b) RESTRICTED: Limited access when License Status is INVALID or UNKNOWN. Core functionality may be limited until compliance issues are resolved. 6. User Responsibilities. As a user of software under this Addendum, You agree to: (a) Maintain security configurations as deployed; (b) Not intentionally trigger Security Bypass conditions; (c) Respond to security alerts in a timely manner; (d) Not remove or disable Security Monitoring components; (e) Keep audit logs for required retention periods; (f) Report security vulnerabilities responsibly. 7. Compliance Requirements. The Work implements Compliance Controls including but not limited to: AC-3: Access Enforcement AU-2: Audit Events AU-6: Audit Review AU-9: Protection of Audit Information CM-6: Configuration Settings SI-4: System Monitoring You agree to operate the Work in a manner consistent with these Compliance Controls. 8. License Restoration. If Your License Status becomes INVALID, You may restore it by: (a) Identifying and resolving all security compliance issues; (b) Running verification tools to confirm resolution; (c) Contacting support if automatic restoration fails. Restoration procedures are documented in the Work's documentation. 9. Termination. In addition to termination conditions in the Base License, Your rights under this Addendum automatically terminate if You: (a) Persistently fail to maintain required security configurations; (b) Intentionally circumvent Security Monitoring; (c) Use the Work in a manner that compromises security; (d) Violate any term of this Addendum. Upon termination, You must cease use of the Work but may retain audit logs for compliance purposes. 10. Amendments. Code Solutions LLC reserves the right to modify this Addendum. Material changes will be communicated via repository announcements, release notes, or in-product notifications. 11. Relationship to Base License. This Addendum supplements but does not replace the Base License. In the event of conflict between this Addendum and the Base License, this Addendum shall control with respect to Security Monitoring features. All other terms of the Base License remain in full effect.
