The Security Center agent provides real-time security protection for your servers by running core processes and loading plug-ins. This topic describes the operating systems and kernel versions supported by the Security Center agent and its related plug-ins.
About the Security Center agent
-
The Security Center agent provides basic protection capabilities through core processes such as information collection and endpoint engines. The core processes depend on specific operating system versions but are not restricted by kernel versions.
Core processes:
Process
Function
AliYunDunMonitor
Host security monitoring and detection
AliSecCheck
Dynamically detects mining viruses, trojans, web shells, and other threats. Provides baseline checks, vulnerability scanning, vulnerability remediation, and asset fingerprint collection.
-
The agent also supports enhanced protection by loading plug-ins such as AliNet, AliHips, and AliWebGuard to intercept threats targeting host networks, process activities, and file modifications. These plug-ins and features (agent self-protection and anti-ransomware) have strict compatibility requirements for both operating system and kernel versions.
Plug-ins and features with kernel version requirements:
