What role does data encryption play in mitigating insider threats?

Data encryption plays a crucial role in mitigating insider threats by protecting sensitive data from unauthorized access. When data is encrypted, it is transformed into a format that cannot be easily understood or accessed without the proper keys or credentials. This adds a layer of security, ensuring that even if an insider gains unauthorized access to the data (for instance, through malicious intent or negligence), they will be unable to read or use it without the corresponding decryption key.

The protection of sensitive information through encryption is particularly important in environments where sensitive data is shared among many users. In the case of an insider threat, where individuals with legitimate access may misuse their privileges, encryption effectively minimizes the risk of data being compromised or exploited.

Other options, while they may have their own relevance in the context of data security, do not capture the primary role of encryption in relation to insider threats. For instance, preventing all forms of data access is not feasible as encryption cannot shield data from all potential access; it merely protects it in a format that is unintelligible without decryption. Incident detection is a separate area that focuses more on identifying and responding to security breaches rather than preventing unauthorized access to data directly. Similarly, while encryption systems can sometimes have implications for data management, simplifying data management is
