Flexible and scalable integrated deep security
The in-depth WEB security protection is not limited to the conventional IPS/AV protection. It provides detailed web application protection for intranet servers. For the most troublesome CC attacks on servers, abnormal outreach, SQL injection, HTTP slow attacks, cross- Common attacks such as website scripts, content detection and verification of various requests from web application clients to ensure their security and legality, real-time blocking of illegal requests, and effective protection of various websites.
Unknown threat detection relying solely on feature analysis is no longer sufficient to deal with complex network environments. In the face of typical APT (Advanced Persistent Threat, advanced persistent threat) attack sandbox technology is one of the most effective methods to defend against APT attacks. It is used to construct Isolated threat detection environment. The H3C Security Gateway sends network traffic to the sandbox for isolation and analysis, and the sandbox draws a conclusion on whether there is a threat. If a traffic is detected as malicious, the device will block the traffic.
Terminal identification, shared management Terminal identification is an important prerequisite for establishing a secure connection to the Internet of Things, and is used to identify terminals in the Internet of Things. When terminal traffic flows through the device, the H3C Security Gateway can analyze and extract terminal information, such as the manufacturer and model of the terminal, and supports sending The user sends the log, prompting the user. At the same time, the application detection method and IPID detection method are used to identify and manage the behavior of sharing the Internet through NAT technology or proxy technology.
Server abnormal outreach detection Server outreach protection is a protection mechanism for intranet servers, which can effectively identify active outreach behaviors of servers, formulate corresponding outreach protection strategies to identify abnormal messages, and output alarm information for management staff for further processing. It provides a basis for the administrator to check the server, thereby preventing the server from becoming a part of the botnet, launching external attacks or infiltrating internally.
