What is the method for detecting bad IP addresses in FortiGate?

The method of detecting bad IP addresses in FortiGate primarily relies on reputation and threat intelligence feeds. This approach leverages external databases and services that maintain continually updated lists of IP addresses considered malicious based on various factors, such as past attack patterns, user reports, and threat activity. When FortiGate devices receive traffic from an IP address, they can compare that address against these known bad IP lists in real-time.

By using automated feeds, FortiGate can respond quickly to emerging threats, actively block malicious traffic, and protect the network from attacks initiated from these identified IP addresses. This method provides a dynamic and proactive way to maintain security, as opposed to static methods or relying solely on internal reports from users. These feeds ensure that the detection mechanism is always up-to-date with the latest threat intelligence, enhancing overall network security efficiency.
