This detection rule identifies file downloads classified as malware by the Cisco Secure Firewall Threat Defense system. The detection process analyzes the `SHA_Disposition` field, specifically looking for the value 'Malware', which indicates that the downloaded file has been flagged as malicious. This rule integrates metadata like the file name, file hash, and threat classification to provide context to the detection. It leverages logs from Cisco Secure Firewall, focusing on FileEvent data. By effectively monitoring these logs, the rule allows security teams to surface and investigate potential file-based threats detected through Cisco's Advanced Malware Protection (AMP) or Threat Grid integrations. If validated as harmful, a detected file download may signify an attempted malware delivery, making this rule essential for endpoint security and threat management.
