What is the HTTP/2 Rapid Reset Attack?

Without diving too deep into technical jargon, the HTTP/2 Rapid Reset Attack is a new form of Distributed Denial of Service (DDoS) attack that targets HTTP/2 servers. It exploits the way HTTP/2 handles connection resets, potentially causing your servers to become overwhelmed and unresponsive.

Cybersecurity and Infrastructure Security Agency (CISA) has released an advisory about this vulnerability, identified as CVE-2023-44487. They recommend that organizations providing HTTP/2 services apply patches when available and consider configuration changes.

The best defense is a good offense. By proactively testing your systems, you can identify vulnerabilities before malicious actors do, giving you the upper hand.

Validate Your Patches and Configurations
