These signatures protected our customers from some of the most common attacks that, even though they aren’t as widely known, could be just as disruptive as something like Olympic Destroyer. Snort is a free, open-source network intrusion prevention system. Cisco Talos provides new rule updates to Snort every week to protect against software vulnerabilities and the latest malware.
