Security-group block

Security groups are introduced in UnrealIRCd 5.0.8. There are two groups by default: known-users (user is identified to services or has high reputation) and unknown-users (all other users).

This way you can ban all users that are "not known" by setting.

Syntax
security-group { identified ; webirc ; reputation-score ; }

Example
The default security group known-users has the following settings: security-group known-users { identified yes; webirc no; reputation-score 24; } If you have no security-group known-users in your configuration file then these are the defaults. If you want to change the settings, then add the block to your config and modify it.

The magic unknown-users security-group
The unknown-users security group is a special group matching users that are NOT matched by the known-users group. In other words:  is the same as   (the exclamation mark prefix meaning 'NOT').
