A security key management system is primarily responsible for handling encryption keys. This includes the generation of keys, their secure distribution, and ongoing management throughout their lifecycle. Effective key management is crucial for maintaining the confidentiality and integrity of sensitive information, as encryption keys are used to protect data from unauthorized access and to ensure that only authorized users can decrypt and access that data.
In particular, a well-functioning key management system ensures that keys are generated using secure methods, stored safely, and rotated or revoked as necessary to mitigate risks associated with key compromise. Furthermore, it often includes auditing capabilities to track the use and handling of keys, thereby enhancing overall security measures.
The other options, while relevant to various aspects of cybersecurity and organizational operations, do not pertain to the specific functions of a security key management system. For instance, documents on employee performance evaluations relate to human resources management, inventories of physical security devices pertain to physical security management, and monitoring user activity logs is associated with intrusion detection and security information management rather than key management.
