Rule Category

POLICY-SOCIAL -- Snort has detected a violation of the corporate policy. Similar to an IOC, this activity may not be directly malicious, but could be a symptom of compromise, or of a misuse of the network. Examples are cryptocurrency mining and strade (Bitcoin, et al). The ISP won’t block these, but corporate policies likely prohibit them. In this case, Snort has detected a violation of social media policy. Some companies choose to disallow some or all social media, or to only allow in-network social sharing. This can prevent simple productivity loss or serious NDA breaches (sharing of files from the internal network, etc.).
