Watchguard Network Security Practice Test

What outcome is expected when using Data Loss Prevention in an HTTPS-proxy?

1. It blocks all outgoing traffic.

2. It detects sensitive information in encrypted traffic.

3. It allows all traffic without inspection.

4. It triggers alerts for all network activity.

The correct answer is: It detects sensitive information in encrypted traffic.

Using Data Loss Prevention (DLP) in an HTTPS-proxy primarily focuses on identifying and protecting sensitive information within encrypted traffic. The technology operates by inspecting data that is transmitted over HTTPS connections, which typically protects communication through encryption. The capability to detect sensitive information in encrypted traffic is crucial because many enterprises handle confidential data such as personal identification information (PII), financial records, and proprietary business information. DLP solutions can analyze this traffic to prevent any unauthorized or accidental leakage of sensitive data, ensuring compliance with regulations and safeguarding the organization against data breaches. Other possible outcomes described in the options do not accurately reflect the function of DLP in an HTTPS-proxy. For instance, blocking all outgoing traffic would be overly restrictive and counterproductive, as it hinders legitimate business operations. Allowing all traffic without inspection contradicts the purpose of DLP, which is to examine and assess data for potential risks. Triggering alerts for all network activity does not specifically focus on sensitive information but instead would result in an overwhelming volume of alerts, making it challenging for security teams to discern genuine threats from normal activities.
