Encryption Transit Rest Protocols Threat Mitigation

Section: Identify the difference between encryption in transit and encryption at rest

Worked example. The correct answer is already marked and every option is explained below, so there is nothing to select here. To answer questions yourself, start the free trial.

An organization is establishing a data security baseline for services such as Secret Manager and Cloud Storage in Google Cloud. The compliance team requires a clear understanding of the protocols applied across data states and the specific threat models each mechanism addresses.

Which statement correctly identifies the technical protocols used for data in transit versus data at rest and the primary security threat each mitigates?

Encryption in transit uses Transport Layer Security (TLS/HTTPS) to mitigate unauthorized physical access to hardware, while encryption at rest uses Pretty Good Privacy (PGP) to mitigate network interception.

Encryption in transit uses the Advanced Encryption Standard (AES-256) to mitigate physical disk removal, while encryption at rest uses Transport Layer Security (TLS/HTTPS) to mitigate network eavesdropping.

Encryption in transit uses Transport Layer Security (TLS/HTTPS) to mitigate network interception, while encryption at rest uses the Advanced Encryption Standard (AES-256) to mitigate unauthorized physical access to storage media.

Encryption in transit uses Secure Shell (SSH) exclusively to mitigate physical disk theft, while encryption at rest uses Transport Layer Security (TLS) to mitigate compromised network switches.
