An XSIAM engineer is reviewing an existing detection rule designed to identify potential brute-force attacks. The current rule generates an alert when more than 5 failed login attempts occur within a 60-second window from a single source IP. However, the SOC wants to differentiate between brute-force attempts targeting standard user accounts and those targeting highly privileged accounts (e.g., 'administrator', 'root'). How can the XSIAM engineer modify the existing content and scoring logic to reflect this requirement?
正解:C
Option C is the most effective and scalable solution for content optimization through scoring. By using a scoring rule, the engineer can dynamically adjust the alert's score based on the context (privileged account target) without duplicating detection rules or making them overly complex. This ensures that the base detection logic remains clean while criticality is assigned post-detection. Options A and B involve duplicating or overly complicating detection rules. Option D changes the detection logic globally. Option E addresses post-alert handling, not the initial scoring.
