Overview
Lightweight Agent Integration for Minimized DEK Exposure and Enhanced Security (Secrets are encrypted using DEKs secured by KEKs generated within an HSM. DEK usage is minimized to reduce memory exposure and attack surfaces.)
Key Features:
- Certificate-Based Secure Communication
- Mutual authentication between Agent and Key4C using HSM-issued certificates.
- Automatically establishes a secure channel to prevent MITM and tampering.
- DEKs remain within the HSM; all cryptographic operations are executed internally.
- Encrypted secrets are stored in etcd; decrypted only upon authorized request and delivered securely to Worker Nodes.
- HSM-Backed KEK for Stronger DEK Protection
- KEKs are generated and stored inside the HSM, never exposed externally.
- All DEK encryption and decryption operations are handled within the HSM.
- DEKs are immediately disposed of after use.
- Only encrypted DEKs are stored; compromised data is unusable without the HSM.
- Compliant with ISMS-P, CSAP, and other regulatory standards.
Highlights
- Secure DEK encryption with KEK generated and managed entirely in HSM
- Minimized DEK usage to reduce attack surfaces and prevent in-memory exposure
- HSM-backed KEK for enhanced DEK security and protection against memory exposure
