srcdsreflection

Explanation

SRCDS, or the Source Dedicated Server, is a tool used by video game developers for hosting and managing multiplayer games. However, if left unsecured, attackers can exploit the protocol and use it to reflect and amplify DDoS attacks.

This event triggers when the Fusion Portal detects a large amount of traffic going to SRCDS servers in a short amount of time. The event is designed to help security teams identify and remediate these types of attacks quickly.

What to Look For

If the srcdsreflection event triggers, security teams should investigate the source of the traffic and determine if it is a legitimate user or a malicious attacker. They should look for a large amount of traffic originating from a single IP address or a small number of IP addresses.

They should also check if the SRCDS servers are secured properly, and update any security settings to prevent future attacks. Finally, the team should consider implementing a DDoS protection solution to prevent future SRCDS reflection attacks from causing damage to their network.
