Question 1150
A retail network separates payment processing from staff browsing yet has no monitoring of endpoint lateral movement. 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 retail network separates payment processing from staff browsing yet has no monitoring of endpoint lateral movement.
Incorrect Answers
Validate peer identity with a trusted certificate chain, correct hostname, certificate validity, and appropriate TLS policy before exchanging sensitive data. This response applies to TLS certificate authentication and PKI, not the controlling requirement in this case. Encryption without authenticated identity does not rule out interception; certificates bind a public key to a verified name under a trust chain. 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 retail network separates payment processing from staff browsing yet has no monitoring of endpoint lateral movement.
Triage software vulnerabilities using version applicability, exploit exposure, available remediation, and business impact alongside published CVE and CVSS data. This response applies to CVE and CVSS vulnerability prioritization, not the controlling requirement in this case. A CVE identifies a disclosed issue and CVSS summarizes severity characteristics; neither alone proves exposure or exploitation of a particular asset. 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 retail network separates payment processing from staff browsing yet has no monitoring of endpoint lateral movement.
Treat retrieved pages, documents, and tool responses as untrusted data and enforce tool authorization outside model-generated instructions. This response applies to Prompt injection trust boundary, not the controlling requirement in this case. Prompt injection occurs when lower-trust content is promoted to instruction authority; blocking unsafe tool effects requires enforcement beyond prompt wording. 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 retail network separates payment processing from staff browsing yet has no monitoring of endpoint lateral movement.
