Security & Data Retention Framework
Standardized protocols for information protection, lifecycle management, and regulatory compliance across all Aevum Zenth divisions.
Information Security Framework
Zero Trust Architecture
All network traffic, internal and external, is treated as untrusted by default. Continuous verification of identity, device health, and context is enforced across all 400 subsidiaries.
Encryption Standards
AES-256-GCM for data at rest, TLS 1.3+ for data in transit. FIPS 140-3 Level 2 validated modules required for all financial and healthcare subsystems.
Network Segmentation
Micro-segmentation isolates critical assets. East-west traffic is filtered via software-defined perimeters. IoT/OT networks are strictly air-gapped or proxied.
Endpoint Detection & Response
Centralized EDR deployment across all corporate and remote devices. Automated containment protocols trigger on anomalous behavior or known IOCs.
Data Retention Matrix
| Data Category | Retention Period | Disposal Method | Regulatory Scope | Status |
|---|---|---|---|---|
| Financial Records (GAAP/IFRS) | 7 Years | Certified Shredding / Crypto-erase | SOC 2, SOX, PCI-DSS | Regulated |
| Employee HR Files | 5 Years Post-Termination | Secure Deletion / Archival Vault | GDPR, CCPA, Local Labor Laws | Standard |
| Healthcare/Patient Data | 10 Years | HIPAA-Compliant Purge | HIPAA, HITECH, ISO 27799 | Regulated |
| Source Code & IP | Indefinite | Air-gapped Backup / DRM | Internal Trade Sec Policy | Archival |
| Network Logs & SIEM Data | 1 Year (Hot) / 3 Years (Cold) | Overwrite / Immutable WORM | ISO 27001, NIST 800-53 | Standard |
| Marketing & Analytics | 2 Years | Anonymization / Aggregate Retention | GDPR, CCPA, ePrivacy | Standard |
Access Control & IAM Protocols
All Aevum Zenth assets require phishing-resistant MFA (FIDO2/WebAuthn or hardware tokens). SMS/TOTP is deprecated for privileged accounts. Conditional access policies evaluate device compliance, geolocation, and risk score before granting session tokens.
Permissions are assigned via centralized IdP synchronized with HRIS. Access follows strict least-privilege models. Quarterly access reviews are mandatory. Privileged access workstations (PAW) are required for administrative functions. Just-in-Time (JIT) elevation is enforced for Tier 1+ systems.
Upon termination or role change, access is revoked within 15 minutes via automated HR-IT integration. Service accounts undergo mandatory rotation. Data ownership is transferred to designated delegates. Former credentials are quarantined for 90 days for forensic audit purposes.
Incident Response & Reporting
- Detection & Triage: Automated alerts routed to SOC Tier 1. Initial severity classification (SEV 1-4) within 15 minutes.
- Containment: Isolate affected endpoints/segments. Preserve forensic artifacts. Activate incident command structure.
- Eradication & Recovery: Remove threat vectors. Patch vulnerabilities. Restore from verified clean backups. Validate system integrity.
- Post-Incident Review: Root cause analysis. Update playbooks. Report to executive steering committee within 72 hours.
