Cortex® XDR™ Agent 7.8 for Linux

To install, use, and uninstall the Cortex® XDR™ agent 7.8 on Linux endpoints, see the references in this topic.
The Cortex® XDR™ agent protects Linux servers by preventing known and unknown malware from running by halting any attempts to leverage software exploits and vulnerabilities to compromise the server. The agent also extends exploit and malware protection to processes that run in Linux containers. When you install the agent on a Linux server that uses containers, it automatically protects any new and existing containerized processes regardless of the container solution (for example, docker). Because Cortex XDR issues the license per Linux server, each container does not consume any additional licenses.
The protection capabilities and features that the Cortex XDR agent for Linux provide depend on the operation modes you choose to deploy the Cortex XDR agent on your Linux server:
  • Kernel Mode
    Cortex XDR agent runs in the supported Kernel version itself.
  • User Space Mode
    Allows you to leverage the protection provide by Cortex XDR agent on Linux distributions running kernel 5.0 and above without loading a kernel module.
    To enable the User Space mode, make sure you:
    • Configure in your Agent Settings Profile the
      Agent Operation Mode
      as
      User Space
      .
    • For new Cortex XDR agents and Cortex XDR agents running on versions earlier than 7.8, the current YAML file is incompatible. You must create and deploy the new YAML installer for Kubernetes based installations.
    User Space mode is available for machines running kernel 5.0 and above.
