Exploit Prevention

Last updated: 2024-01-23 15:44:44

Exploit prevention is a virtual patch-based system developed by the Tencent Cloud security team to defend against frequent 0-day and N-day vulnerabilities. It integrates Tencent's vulnerability mining and real-time high-risk vulnerability alerting technologies to capture and analyze vulnerabilities, generate virtual patches based on Tencent's expertise, and automatically make the patches effective in CVM instances. This helps effectively block hacker attacks and gain more time for vulnerability fix.
