Security & Compliance

Implemented Controls

  • Access Control: Role-based (RBAC) via Active Directory integration
  • Network Segmentation: Docker network isolation, VLAN segmentation
  • Data Encryption: LUKS at-rest, TLS 1.3 in-transit
  • Monitoring: Real-time anomaly detection via Wazuh + Splunk SIEM
  • Backup/DR: Veeam B&R, Acronis Cyber Protect Cloud, Datto BCDR (RTO <4hr, RPO <15min) [1]
