In filtering System Log events related to suspicious sign-in requests, which query is valid?

• A. eventType eq "security.threat.detected" and severity eq "WARN"
• B. eventType eq "security.access.granted" and authStatus eq "SUCCESS"
• C. eventType eq "security.access.denied" and severity eq "HIGH"
• D. eventType eq "user.signin" and severity eq "INFO"

Answer: (A)

The correct choice involves filtering for system log events that indicate a potential security threat. By utilizing a query that specifies "eventType eq 'security.threat.detected'" along with "severity eq 'WARN'", you are focusing on events that are explicitly related to security threats which have been detected, and categorizing them based on their severity level as a warning. This approach is particularly relevant in an administrative context, as it helps identify signs of suspicious activity, such as potential unauthorized access attempts or breaches. Administrators need to act on warning-level events, as they may indicate that a significant issue could arise if not investigated further. The other choices relate to different types of events that do not specifically indicate suspicion or a security threat. For example, granted access and successful authorization statuses do not reflect signs of suspicious behavior, while access denied events with high severity might suggest an issue after the fact, rather than detecting a potential threat in real-time. Sign-in events with info-level severity provide basic information but do not alert an administrator to potential suspicious activity. Therefore, the query that focuses on detecting security threats is most appropriate for addressing concerns about suspicious sign-in requests.
