To install, use, and uninstall the Cortex XDR agent 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. The Palo Alto Networks Compatibility Matrix provides more information about supported versions.
User Space Mode
This mode allows you to leverage the protection provided by Cortex XDR agent on Linux distributions running Kernel 5.0 and above without loading a kernel module. The Palo Alto Networks Compatibility Matrix provides more information about supported versions.
Change to User Space operation mode is supported from Cortex XDR agent version 7.7 and later.
To enable User Space mode, make sure of the following:
In the Agent Profile, configure the Agent Operation Mode as User Space.
You must create and deploy the new YAML installer for Kubernetes based installations.
The following table details protection capabilities provided according to each operation mode.
Protection Capabilities | Kernel | User Space |
