ISC2 Governance, Risk and Compliance (CGRC) Practice Question
While designing a new system, the security team must implement a control that specifically safeguards the confidentiality of data at rest inside the system boundary. Which of the following controls best fits this requirement?
Require annual security awareness training for all users.
Schedule weekly integrity hash checks on log files.
Encrypt the database using AES-256 and hardware security module integration.
Establish a disaster recovery site in a different geographic region.
Encrypting the database with AES-256 and protecting the keys in a hardware security module is a technical control that directly enforces confidentiality for data at rest. Security-awareness training is an operational control that addresses human behavior, not data protection. Integrity hash checks verify that log files are unaltered, supporting integrity rather than confidentiality. A geographically separated disaster recovery site enhances availability by reducing downtime after an outage, but it does not protect the secrecy of stored information.
