Blacklist

Blacklist

A blacklist filters packets based on source VPNs and source IP addresses. Compared with ACLs, the blacklist uses simpler matching rules and therefore can filter packets at a higher speed. The blacklist can effectively block the packets sent from specific IP addresses. Blacklist entries can be manually configured or dynamically generated.

As shown in Figure 5-5, the IP address of user B is in the blacklist, so packets from user B are discarded by the firewall.

Figure 5-5  Blacklist

Blacklist Features Supported by the Device

You add entries to the blacklist manually. In addition, if the device detecting an IP sweeping attack or port scanning attack, it adds the attacking IP address or port to the blacklist. Then, all the packets from this IP address or port are rejected within a certain period. You can set an aging time for entries in the blacklist.

The firewall discards all the packets from the blacklisted IP addresses no matter whether the packets are permitted by the ACL.

You can export entries in a blacklist to a file or import entries to a blacklist from a file.
