Question 150
A security architect wants compensating controls when an internet-facing application requires access to a sensitive data tier. Which Cisco security control or operational response BEST addresses the stated need?
Explanation
Correct Answer
Layer identity, network segmentation, endpoint, visibility, and policy enforcement around critical assets using Cisco SAFE-style security architecture principles. This control addresses the failure mechanism and narrows the enforcement boundary. Defense in depth combines complementary independent controls; stacking duplicate products at one boundary does not protect other attack paths. Confirm pre-change conditions using: Inspect business assets and trust boundaries, control coverage, failure paths, enforcement logs, and incident recovery dependencies. Situation: A security architect wants compensating controls when an internet-facing application requires access to a sensitive data tier.
Incorrect Answers
Protect remote workers with supported Cisco Secure Client VPN authentication, endpoint posture, split-routing policy, and controlled profile distribution. This response applies to Remote access VPN client controls, not the controlling requirement in this case. Remote access VPN authenticates a user or device and creates protected transport; reachability still depends on routes, authorizations, and posture. For this scenario, the targeted action is: Layer identity, network segmentation, endpoint, visibility, and policy enforcement around critical assets using Cisco SAFE-style security architecture principles. Situation: A security architect wants compensating controls when an internet-facing application requires access to a sensitive data tier.
Combine suspicious message reporting, web destination inspection, reputation controls, and user training with enforceable authentication policies. This response applies to Phishing containment and domain verification, not the controlling requirement in this case. A secure email channel and DNS/web controls reduce exposure but cannot certify that every newly registered domain is benign. For this scenario, the targeted action is: Layer identity, network segmentation, endpoint, visibility, and policy enforcement around critical assets using Cisco SAFE-style security architecture principles. Situation: A security architect wants compensating controls when an internet-facing application requires access to a sensitive data tier.
Prevent SQL injection by separating untrusted field values from query structure using parameter binding and constrained database privileges. This response applies to SQL injection and parameterized queries, not the controlling requirement in this case. SQL injection exploits code/data confusion; input sanitization alone is weaker than parameterization plus least privilege. For this scenario, the targeted action is: Layer identity, network segmentation, endpoint, visibility, and policy enforcement around critical assets using Cisco SAFE-style security architecture principles. Situation: A security architect wants compensating controls when an internet-facing application requires access to a sensitive data tier.
