This rule monitors network traffic for HTTP POST requests directed toward specific destination ports (443 or 8770) that return HTTP status codes in the 4xx range (client errors), excluding known legitimate URI paths. This pattern may indicate scanning activity, exploitation attempts, or unauthorized access attempts against internal services or misconfigured applications.
