Question 750
An employee uses an unsanctioned remote-access application over HTTPS on an otherwise permitted outbound port. Which TWO complementary steps provide the most defensible remediation and its supporting assessment? Select TWO.
Explanation
Correct Answers
Inspect application detectors, URL category verdicts, rule conditions, encrypted-session visibility, and identity matches. This checks the relevant condition before an engineer modifies production access or detection behavior. An IP address alone may host many services; application or URL inspection adds context but must have sufficient visibility to classify traffic. The controlled response would be: Apply application-aware restrictions and appropriate URL categories to FTD policies while checking TLS and application identification limits. This supplies the diagnostic evidence needed for the complementary action. Situation: An employee uses an unsanctioned remote-access application over HTTPS on an otherwise permitted outbound port.
Apply application-aware restrictions and appropriate URL categories to FTD policies while checking TLS and application identification limits. This control addresses the failure mechanism and narrows the enforcement boundary. An IP address alone may host many services; application or URL inspection adds context but must have sufficient visibility to classify traffic. Confirm pre-change conditions using: Inspect application detectors, URL category verdicts, rule conditions, encrypted-session visibility, and identity matches. This is the implementation portion of the complementary pair. Situation: An employee uses an unsanctioned remote-access application over HTTPS on an otherwise permitted outbound port.
Incorrect Answers
Inspect VPN event traces, IKE negotiation state, certificate or PSK errors, UDP 500/4500, and proposal mismatches. This step could matter for FTD IKE negotiation failure isolation but is not part of the required complementary pair for this case. The paired steps are: Apply application-aware restrictions and appropriate URL categories to FTD policies while checking TLS and application identification limits. and Inspect application detectors, URL category verdicts, rule conditions, encrypted-session visibility, and identity matches. Situation: An employee uses an unsanctioned remote-access application over HTTPS on an otherwise permitted outbound port.
Implement Cisco Secure Firewall access control policy with explicit zone, address, application, and rule-order scope, logging decisions at relevant boundaries. This step could matter for FTD access control rule ordering but is not part of the required complementary pair for this case. The paired steps are: Apply application-aware restrictions and appropriate URL categories to FTD policies while checking TLS and application identification limits. and Inspect application detectors, URL category verdicts, rule conditions, encrypted-session visibility, and identity matches. Situation: An employee uses an unsanctioned remote-access application over HTTPS on an otherwise permitted outbound port.
Compliant users receive intended protected routes and application access without exposing unrelated networks. This step could matter for Cisco Secure Client remote VPN policy but is not part of the required complementary pair for this case. The paired steps are: Apply application-aware restrictions and appropriate URL categories to FTD policies while checking TLS and application identification limits. and Inspect application detectors, URL category verdicts, rule conditions, encrypted-session visibility, and identity matches. Situation: An employee uses an unsanctioned remote-access application over HTTPS on an otherwise permitted outbound port.
