A Complete Guide for Telecom DDoS Mitigation
▶ Download the full case study
DDoS, an attack that compromises multiple devices into a botnet and simultaneously directs traffic at a target server to cause service disruption, is among the most frequently observed attacks and remains persistent. The simplicity of executing DDoS has led to sustained growth in attack scale, accompanied by continuous evolution of attack techniques.
These attacks can be especially damaging to telecommunications providers with the large number of users. This case study examines the major DDoS attack types, the common mitigation approaches employed by telecommunications providers, and how AhnLab DPX can effectively address ever-evolving DDoS attacks.
DDoS Mitigation Methods
1. Threshold rule-based mitigation
Threshold-based rules detect and respond to DDoS attacks by counting packets and identifying traffic that exceeds predefined thresholds. This approach carries the risk of blocking legitimate users and is less effective against low-volume attacks.
2. Authentication-based mitigation
Authentication-based mitigation addresses automated and bot-driven attacks by validating behaviors through authentication mechanisms. Because adversaries rely on automated bots rather than manual execution, this approach counters a broad range of DDoS patterns. Even in low-volume attack scenarios, authentication mechanisms identify bot-generated traffic and mitigate attacks
3. Scrubbing center
The telecommunications industry is one of the sectors frequently exposed to ultra-large-scale DDoS attacks. In particular, their business-critical services that require continuous availability require mitigation methods capable of handling ultra-large-scale DDoS attacks. A DDoS mitigation in form of SECaaS (Security-as-a-Service), commonly known as a scrubbing center, addresses this requirement by redirecting DDoS traffic to an external infrastructure for large-scale mitigation.
