Question 490
A Secure Access policy blocks known malicious domains but cannot evaluate file contents for HTTPS uploads under a no-decryption exception. Which Cisco security control or operational response BEST addresses the stated need?
Explanation
Correct Answer
Apply internet security controls with an authorized TLS inspection strategy and define exceptions for sensitive or unsupported applications. This control addresses the failure mechanism and narrows the enforcement boundary. HTTPS inspection enables deeper policy evaluation on permitted traffic but requires trust deployment, privacy governance, and compatibility testing. Confirm pre-change conditions using: Inspect certificate trust, destination classification, decryptability, business exceptions, inspection policy, and client breakage. Situation: A Secure Access policy blocks known malicious domains but cannot evaluate file contents for HTTPS uploads under a no-decryption exception.
Incorrect Answers
Correlate Investigate domain information with DNS activity, source endpoint, time range, and threat intelligence before escalating. This response applies to Investigate infrastructure attribution and false positives, not the controlling requirement in this case. Domain attribution may involve shared infrastructure and dynamic resolution; a risky domain does not imply every neighbor on the IP is malicious. For this scenario, the targeted action is: Apply internet security controls with an authorized TLS inspection strategy and define exceptions for sensitive or unsupported applications. Situation: A Secure Access policy blocks known malicious domains but cannot evaluate file contents for HTTPS uploads under a no-decryption exception.
Apply AI service visibility and policy to protect sensitive inputs, approved destinations, and user identity when staff use external generative AI tools. This response applies to AI application guardrails and shadow AI, not the controlling requirement in this case. A corporate AI policy requires enforceable data handling and approved services; blocking a few keywords does not alone control all exfiltration paths. For this scenario, the targeted action is: Apply internet security controls with an authorized TLS inspection strategy and define exceptions for sensitive or unsupported applications. Situation: A Secure Access policy blocks known malicious domains but cannot evaluate file contents for HTTPS uploads under a no-decryption exception.
Configure Secure Internet Access policy in Cisco Secure Access to allow needed business categories and deny unsafe domains or web destinations for scoped identities. This response applies to Cisco Secure Access internet use policy, not the controlling requirement in this case. Cloud-delivered DNS and web protection depends on correct matching rules and traffic steering; a broadly permissive rule can shadow a later block. For this scenario, the targeted action is: Apply internet security controls with an authorized TLS inspection strategy and define exceptions for sensitive or unsupported applications. Situation: A Secure Access policy blocks known malicious domains but cannot evaluate file contents for HTTPS uploads under a no-decryption exception.
