CHAPTER 17
Reputation Filter
17.1 Overview
Use the Reputation Filter screens to configure settings for IP Reputation, DNS Threat Filter and URL Threat
filtering.
The following table shows the number of entries allowed in each screen.
17.1.1 What You Need to Know
IP Reputation
IP reputation checks the reputation of an IP address from a database. An IP address with bad
reputation associates with suspicious activities, such as spam, virus, and/or phishing. The Zyxel Device will
respond when there are packets coming from an IPv4 address with bad reputation.
DNS Threat Filter
DNS threat filtering inspects DNS queries made by clients on your network and compares the queries
against a database of blocked or allowed Fully Qualified Domain Names (FQDNs). The Zyxel Device DNS
Threat Filter will either drop the DNS query or reply to the user with a fake DNS response.
URL Threat Filter
URL threat filtering compares access to specific URLs against a database of blocked or allowed sites.
Sites on the database are sorted into categories such as:
