Cleartext Protocol Usage Via Netflow
This rule detects the usage of cleartext protocols for transmitting sensitive information, such as account usernames and authentication credentials, across networks. It specifically monitors Netflow data for connections to common ports associated with unencrypted services like HTTP, FTP, Telnet, and various database/application ports. The goal is to ensure that all sensitive data and administrative access utilize encrypted channels to prevent credential access and data interception.
