The IPDS or Intrusion and Prevention Detection System section within the IPDS module permits to configure and set protection rules at System or Farm service level.IPDS is a module which implements a group of techniques designed to detect, analyze and block network attacks.
On the other hand, RBL or Real-time Blackhole Lists are community-based, central repositories for IP Reputation. RBLs are most commonly used to identify web-based comment spam, or network attackers. The repository maintain a list of IP that can be blocked (blacklisted) on servers, thus lowering the probability of an attack to our servers.
This section shows a list of your actual RBL rules.
The fields of the list are:
NAME. The unique describing name of the rule.
Only Logging. If activated, the rule has no real effect, just writes output to the syslog for debugging purposes.
