CAS-004 Exam Dumps : CompTIA SecurityX Certification Exam

A Hardware Security Module (HSM) provides the best solution for securely backing up MFA seeds in a central, offline location with minimal management overhead. HSMs are specialized hardware devices designed for cryptographic key management, including storing sensitive data like MFA seeds securely. HSMs offer high levels of protection against tampering and provide offline security, making them an ideal choice for backing up cryptographic materials. CASP+ recognizes HSMs as critical components for managing and securing cryptographic keys in centralized, secure environments.

Key escrow is a process that involves storing encryption keys with a trusted third party, such as a CASB (Cloud Access Security Broker) or a government agency. Key escrow can enable authorized access to encrypted data in case of emergencies, legal issues, or data recovery. However, key escrow also introduces some risks and challenges, such as trust, security, and privacy.References:

Galois/Counter Mode (GCM) is an AES mode of operation that provides both confidentiality and data integrity. It is well-suited for processing streams of data, making it ideal for streaming video services. GCM is known for its strong cryptographic security and good performance, which aligns with the legacy cipher's characteristics and the streaming service's requirements.
