DDoS attack: the need for a response plan

Just as a demonstration blocks access to a road, a DDoS attack aims to hinder legitimate access to a web service for its legitimate users.

This type of attack, frequently seen in the 90s and early 2000s, has seen a resurgence over the last five years, particularly as a means of transmitting geopolitical messages. A DDoS attack is a form of cyberattack where thousands of computers (often themselves infected with malware), are used to flood a target with traffic, overwhelming it and making it unavailable to legitimate users.

 

What you need to do to prepare for a DDoS attack :

 

  • Identify critical assets and services: Every server offering an Internet-accessible service can be the target of a DDoS attack. It is therefore crucial to identify them correctly, but also to understand the interdependencies between them to accurately assess the potential impact of such an attack.

 

  • Understanding network access: Minimise the services exposed to the Internet and their exposure in order to reduce your attack surface.

 

  • Subscribe to a DDoS protection service: Subscribe to a DDoS protection service that monitors, detects and absorbs harmful traffic targeting your network.
