Rule Category

PROTOCOL-IMAP -- Snort alerted on Internet Message Access Protocol (IMAP) traffic, an email retrieval system for clients over TCP/IP connection. This protocol handles emails on a remote server, so all actions are processed on that server rather than the user client. This protocol is vulnerable to injection, restriction and process evasions, leaks, relay abuse, and other attacks.
