What type of protection can prevent unauthorized information disclosure through encryption?

Data Loss Prevention (DLP) is essential for preventing unauthorized information disclosure through encryption. DLP solutions monitor, detect, and respond to data handling practices that may lead to leaks of sensitive information. By encrypting data, DLP systems ensure that even if unauthorized individuals access the data, they cannot read it without the necessary decryption keys, effectively safeguarding its confidentiality.

DLP often implements encryption as part of a broader strategy for protecting sensitive data at rest, in transit, or in use. This capability is crucial in sectors that handle sensitive information, such as finance and healthcare, as it helps organizations comply with regulatory requirements and protects against potential data breaches.

In contrast, firewalls primarily focus on monitoring and controlling incoming and outgoing network traffic based on predetermined security rules but do not directly manage data confidentiality. Intrusion Detection Systems (IDS) serve to detect and alert on potential intrusions within a network but do not prevent unauthorized access through encryption. Access Control Lists (ACL) help regulate who can access certain resources or networks, which is important for overall security but does not specifically address protecting data through encryption itself.
