Question 10
When validating a security detection workflow, the team notes: A remote-access gateway reports hundreds of failed SSL VPN logins for one account overnight, followed by a single successful login. Which ongoing operational control best reduces the risk of recurrence?
Explanation
Correct Answer
This safeguard directly addresses ssl vpn login failure burst: Build account-centric authentication alerts with success-after-failures logic and contextual enrichment. The risk being prevented is: A high failure rate followed by success can suggest credential guessing but requires careful review of source and authentication method. A safeguard aimed at another fault would not control this issue.
Incorrect Answers
A tunnel negotiation success does not establish that subsequent policy, routing or encrypted application flows were permitted. “Validate tunnel uptime and business traffic reachability as separate acceptance measures” would remedy that alternative situation, but it would not correct the present issue: a high failure rate followed by success can suggest credential guessing but requires careful review of source and authentication method.
“Review category changes and keep exception requests tied to specific logged URLs and users” is the supported response when a category-based web-filter policy can block a site even without an identified malware signature. Here the decisive response is “Build account-centric authentication alerts with success-after-failures logic and contextual enrichment”, so that different intervention does not meet the stated requirement.
IP-based geolocation can reflect VPN egress or cloud proxies, so an unusual country is a risk signal rather than absolute identity proof. “Use geolocation anomalies as one factor in a privileged access review rather than a standalone compromise verdict” applies to that other condition. The reported evidence is a remote-access gateway reports hundreds of failed SSL VPN logins for one account overnight, followed by a single successful login; this alternative would address the wrong dependency.
