Question 250
An employee syncs business documents to an approved corporate SaaS tenant and triggers the same byte-volume threshold as a suspicious upload. Which TWO complementary steps provide the most defensible remediation and its supporting assessment? Select TWO.
Explanation
Correct Answers
Correlate unusual encrypted uploads and sanctioned cloud-service use with identity, DLP, destination, and endpoint telemetry. This control addresses the failure mechanism and narrows the enforcement boundary. HTTPS encryption does not prove the destination or data transfer is authorized; flow, SaaS policy, and endpoint context can reveal risk without blindly decrypting all traffic. Confirm pre-change conditions using: Inspect flow byte asymmetry, SaaS tenant, DLP events, process initiator, upload time, and user job role. This is the implementation portion of the complementary pair. Situation: An employee syncs business documents to an approved corporate SaaS tenant and triggers the same byte-volume threshold as a suspicious upload.
Inspect flow byte asymmetry, SaaS tenant, DLP events, process initiator, upload time, and user job role. This checks the relevant condition before an engineer modifies production access or detection behavior. HTTPS encryption does not prove the destination or data transfer is authorized; flow, SaaS policy, and endpoint context can reveal risk without blindly decrypting all traffic. The controlled response would be: Correlate unusual encrypted uploads and sanctioned cloud-service use with identity, DLP, destination, and endpoint telemetry. This supplies the diagnostic evidence needed for the complementary action. Situation: An employee syncs business documents to an approved corporate SaaS tenant and triggers the same byte-volume threshold as a suspicious upload.
Incorrect Answers
Inspect known endpoint MAC registrations, profiling data, switch authentication order, RADIUS policy, and allowed destination flows. This step could matter for MAB fallback and printer restriction but is not part of the required complementary pair for this case. The paired steps are: Correlate unusual encrypted uploads and sanctioned cloud-service use with identity, DLP, destination, and endpoint telemetry. and Inspect flow byte asymmetry, SaaS tenant, DLP events, process initiator, upload time, and user job role. Situation: An employee syncs business documents to an approved corporate SaaS tenant and triggers the same byte-volume threshold as a suspicious upload.
A linked multi-source incident supports proportional containment with evidence from affected devices and services. This step could matter for Cisco XDR cross-source incident correlation but is not part of the required complementary pair for this case. The paired steps are: Correlate unusual encrypted uploads and sanctioned cloud-service use with identity, DLP, destination, and endpoint telemetry. and Inspect flow byte asymmetry, SaaS tenant, DLP events, process initiator, upload time, and user job role. Situation: An employee syncs business documents to an approved corporate SaaS tenant and triggers the same byte-volume threshold as a suspicious upload.
Identify suspicious DNS-based data movement using query entropy, length, volume, domain ownership, and endpoint context before containment. This step could matter for DNS tunneling exfiltration detection but is not part of the required complementary pair for this case. The paired steps are: Correlate unusual encrypted uploads and sanctioned cloud-service use with identity, DLP, destination, and endpoint telemetry. and Inspect flow byte asymmetry, SaaS tenant, DLP events, process initiator, upload time, and user job role. Situation: An employee syncs business documents to an approved corporate SaaS tenant and triggers the same byte-volume threshold as a suspicious upload.
