- Trusted Platform Module (TPM)
- Definition: TPM is both a specification for a cryptoprocessor chip integrated into a mainboard and the general name for implementations of this specification.
- Purpose: TPM chips are used to store and process cryptographic keys, primarily for hardware-supported hard drive encryption systems.
- Security: Hardware-based implementations like TPM are considered more secure compared to software-only encryption methods because they provide a dedicated, tamper-resistant environment for key management.
- Constrained or Restricted Interface
- Definition: A security feature implemented within an application to limit what users can do or access based on their assigned privileges.
- Purpose: Helps enforce the principle of least privilege by ensuring that users only have access to the functions and data necessary for their role, thereby reducing the risk of unauthorized actions or access.
These security capabilities are critical for maintaining the integrity, confidentiality, and proper functioning of information systems, particularly in environments requiring robust protection against unauthorized access and tampering.
