Introduction
The blacklist feature is an attack prevention method that filters packets by IP addresses or address object groups in blacklist entries. Compared with ACL-based packet filtering, IP blacklist filtering is simpler and provides effective screening at a faster speed.
Blacklist entries can be manually added or dynamically learned:
· You can manually add an IP blacklist entry. These entries do not age out by default. You can set an aging time for each entry.
· The device can automatically add IP blacklist entries when collaborating with scanning attack detection. Each dynamically learned IP blacklist entry has an aging time, which is user configurable. Make sure adding the attacker's IP address to the IP blacklist is specified as the scanning attack prevention action.
