This allows customers to timely and comprehensively understand the security status of the server, transforming security from traditional security event protection into a continuous security response and processing process. The functions cover multiple dimensions such as weak password detection, software vulnerability detection, brute force cracking prevention, web backdoor, shell detection, etc., achieving continuous and in-depth protection of server security.
