Enterprise Endpoint Hardening: BitLocker Encryption, TPM 2.0 & Credential Guard Architecture
By Dorynix Security Architecture Group• Verified Deployment Architecture Series
1. BitLocker Drive Encryption & TPM Platform Validation
Full-volume encryption secures system partitions against offline extraction. TPM 2.0 stores master volume encryption keys securely within tamper-resistant silicon. Enforce pre-boot authentication PIN policies for high-security mobile workstations to protect against physical direct-memory-access (DMA) bus sniffing.
2. Virtualization-Based Security (VBS) & Hypervisor-Protected Code Integrity
Virtualization-based Security (VBS) uses hardware virtualization features to create an isolated memory region separate from the standard operating system. Hypervisor-Protected Code Integrity (HVCI) utilizes this environment to strictly validate kernel-mode drivers against cryptographic code-signing policies before execution.
3. Credential Guard & Pass-the-Hash Defense
Windows Defender Credential Guard isolates Local Security Authority Subsystem Service (LSASS) secrets inside a virtual container inaccessible even to local administrators, rendering credential dumping utilities like Mimikatz ineffective.
