What is FDS (Fraud Detection System)?

FDS stands for Fraud Detection System, which is a security system that blocks malicious activity and identifies users who attempt fraudulent transactions based on abnormal payment patterns.

This means that the system is capable of identifying users who access services with malicious intent. FDS aims to protect services and users in everyday activities like logging in, getting a subscription, or financial transactions.

IP Intelligence  Makes Criminal IP FDS Different

FDS needs to be able to detect malicious users and activities in real-time. However, there are a lot of issues with the existing FDS detection process. 

Issues With the Existing FDS 

  1. Building FDS requires a vast number of logs.
  2. Many companies do not have a system for recording logs themselves.
  3. Log analysis and learning take a long time.

FDS That Applies IP Intelligence 

To compensate for the aforementioned FDS issues, Criminal IP FDS proposed a method to utilize IP intelligence in its system. Malicious users attempt to connect and abuse through infected or bypassed IP addresses. Therefore, it is possible to determine the maliciousness of the user attempting to pay or log in with just one access IP address without performing complex log analysis like the traditional FDS. In fact, Criminal IP FDS makes the same or more detections than analyzing the entire activity log in a much shorter period of time. 

The Following Shows How Criminal IP Identifies Malicious Users

For example, let’s say a user is attempting to bypass the connection through a VPN IP address. When this user accesses to a service that has Criminal IP FDS integrated in, the network security automatically activates Criminal IP APIs. If the API results are identified as a VPN IP, results are sent to the network security device, and it can be used to block the user’s connection.
