IP Reputation Filtering
This features adds support for reputation filtering in the firewall policies.
Currently, there are five reputation levels in the internet-service database (ISDB), and custom reputation levels can be defined in a custom internet-service. This features allows firewall policies to filter traffic according to the configured reputation level. If the reputation level of either the source or destination IP address is equal to or greater than the level set in the policy, then the packet is forwarded, otherwise, the packet is dropped.
The five default reputation levels are:
1 |
Known malicious sites related to botnet servers, phishing sites, etc. |
2 |
Sites providing high risk services, such as TOR, proxy, P2P, etc. |
3 |
Unverified sites. |
4 |
Reputable sites from social media, such as Facebook, Twitter, etc. |
5 |
Known and verified safe sites, such as Gmail, Amazon, eBay, etc. |
The default minimum reputation level in a policy is zero, meaning that the reputation filter is disabled.
For IP addresses that are not included in the ISDB, the default reputation level is three.
The default reputation direction is destination
.
To set the reputation level and direction in a policy:
config firewall policy edit 1 set uuid dfcaec9c-e925-51e8-cf3e-fed9a1d42a1c set srcintf "wan2" set dstintf "wan1" set dstaddr "all" set reputation-minimum 3 set reputation-direction source set action accept set schedule "always" set service "ALL" set logtraffic all set auto-asic-offload disable set nat enable next end
Packets from the source IP address with reputation levels three, four, or five will be forwarded by this policy.
