Introduction
Vormetric CoreGuard is an integrated data protection product that secures data-at-rest through the use of encryption, access controls and host integrity protection.CoreGuard Architecture
The CoreGuard System features an innovative architectural design that combines highly effective security and performance with a high level of transparency and ease of management. CoreGuard consists of software Policy Enforcement Modules (PEMs) and a Security Server appliance cluster. The thin CoreGuard PEMs are installed on hosts that serve as access points to protected information, where they can identify the context of data access requests, protect the integrity of the host and verify the authenticity of its applications. The Security Server provides a central point of management as well as secure storage for information protection policies and keys.
The secure nature of the CoreGuard design stems from its separation of the PEM from the Security Server appliance. The PEM provides the contextual information needed to validate access requests against fine-grain information protection policies, enforces the use of authentication mechanisms that validate the identity of the data requestor, and protects the integrity of the applications and critical configuration files. The Security Server stores the information protection policies and encryption keys in a hardened, physically detached device. This separation enables the enforcement of segregation of duties policies by permitting the assignment of policy management to security administration while allowing IT administration to manage the host server platform.
