Check for open IRC-Server Port

If the result is positive, there is no need for further action. If the result is negative, please read the following instructions.

Result positive The IRC-port on your server is not active.
Result negativ The IRC-port on your server is active.
Description There port which is commonly used for the "IRC" program is active on your server. This program is usually used for a chat server. Criminal often use IRC to control their botnets.
Background Programs running on your server can open so-called ports. A port can be imagined as a door. With some ports (doors), you want them to be open so that, for example, customers can visit your website. With other ports (doors), you don't want them to be open. You should close ports that you don't use. This will allow attackers to attack your server from fewer sites.
Consequence Open ports do not represent a _direct_ vulnerability for now. The configuration of your server, however, increases the attack surface for attackers. You should not offer services that you do not use and it is best to disable insecure services altogether.
Solution/Tips You should switch this service off if you do not require it. If you use IRC, you need not do anything.
