DDoS Protection

Large-scale Network Traffic Attack Detection & Response

The service detects and blocks DDoS (Distributed Denial of Service) attacks, which disrupt the network traffic by overwhelming the target with a flood of traffic using multiple servers. Constant monitoring detects external traffic attacks and protects servers within the DMZ. In the case of an attack, the continuity of web service is guaranteed by minimizing traffic overload to the origin server by blocking and distributing traffic.

Overview

  • Fast Attack Detection

    In the case of large inbound traffic, real-time detection of DDoS attacks is provided. Constant updates on security checklist also enable responses to the latest attack methods.

  • Efficient Blocking

    When an attack is detected, only the large traffic at Layer 3 and 4 are blocked to ensure service availability and normal access to the website of general users.

  • Reliable Web Service Operation

    Efficient responses to external security threats are ensured based on experience in large scale network operation and 24/7/365 security control.
