How Do I Enable or Disable HSS Self-protection?

HSS self-protection provides the following functions:

  • Self-protection in Windows: Prevent malicious programs from uninstalling the agent, tampering with HSS files, or stopping HSS processes.
  • Self-protection in Linux: Prevent malicious programs from stopping the HSS process and uninstalling the agent.

Self-protection is disabled by default. To enable or disable this function, perform the operations described in this section.

Constraints

  • HSS self-protection is available only in the HSS premium, WTP, and container editions. It can be used only if the Linux agent version is 3.2.12 or later or the Windows agent version is 4.0.18 or later.
  • Self-protection in Windows depends on antivirus detection, HIPS detection, and ransomware protection. It takes effect only when more than one of the three functions are enabled. For more details, see:
  • Enabling the self-protection policy has the following impacts:
    • The agent cannot be uninstalled on the control panel of a Windows server. It can be uninstalled on the HSS console.
    • In the agent installation path C:\Program Files\HostGuard on a Windows server, you can only access the log and data directories (and the upgrade directory, if your agent has been upgraded).
    • On a Linux server, the agent cannot be uninstalled using commands. It can be uninstalled on the HSS console.
    • If you run a command on a Linux server to stop or restart HSS, you need to enter a verification code, which is displayed in the command output after you run the stop or restart command.
    • Hide the process information of HSS.
