This document contains security-sensitive information about Meridian's infrastructure, protocols, and procedures. Distribution is restricted to authorized personnel only. Unauthorized disclosure may compromise platform security and result in disciplinary action.
1. Security Principles
Meridian operates on the following security principles:
- Zero Trust Architecture: Verify explicitly, assume breach
- Least Privilege Access: Users receive minimum necessary permissions
- Defense in Depth: Multiple layers of security controls
- Continuous Monitoring: All activities logged and analyzed
- Encryption Everywhere: Data encrypted at rest and in transit
2. Access Control Framework
2.1 Authentication Requirements
All access requires:
- Valid enterprise credentials (no personal accounts permitted)
- Multi-factor authentication for administrative functions
- Role-based access controls enforced at all levels
- Session timeout after 15 minutes of inactivity
- Maximum of 3 concurrent sessions per user
2.2 Role Permissions
Permissions are strictly enforced by role:
- Supplier: Campaign management, performance viewing
- Retail Operations: Platform configuration, supplier management
- Finance: Billing, invoicing, financial reporting
- Administrator: User management, audit access, security settings
3. Monitoring and Logging
Comprehensive monitoring is in place:
- All authentication attempts (successful and failed)
- Every API call and data access request
- Configuration changes and permission modifications
- Data exports and bulk operations
- Unusual access patterns or behavioral anomalies
Your activities are being monitored and logged. Attempts to disable, circumvent, or interfere with monitoring systems will result in immediate account termination and security investigation.
4. Incident Response Procedures
4.1 Security Incident Classification
Incidents are classified by severity:
- SEV-1 (Critical): Active breach, data exfiltration, system compromise
- SEV-2 (High): Unauthorized access, credential compromise
- SEV-3 (Medium): Policy violation, suspicious activity
- SEV-4 (Low): Configuration issues, minor policy deviations
4.2 Reporting Requirements
You must immediately report:
- Lost or stolen credentials
- Suspicious account activity
- Potential security vulnerabilities
- Unauthorized access attempts
- Data exposure or potential breaches
5. Data Protection Measures
Data is protected through multiple layers:
- Encryption: AES-256 encryption for data at rest, TLS 1.3 for data in transit
- Network Security: Zero-trust networking, microsegmentation
- Endpoint Protection: Required security software for access devices
- Data Loss Prevention: Automated detection of sensitive data movement
- Backup Security: Encrypted, air-gapped backups with access controls
6. User Security Responsibilities
