Cortex XDR for Linux Requirements – EXOsecure

The Cortex XDR agent for Linux has the following requirements:
  • 2.3 GHz
  • 4GB; 8GB recommended
Hard disk space
  • 10GB
  • x86 64-bit
Operating system versions
Kernel version
  • 2.6.32
  • To perform malware analysis of ELF files, and collect data for EDR and behavioral threat analysis, the Cortex XDR agent for Linux requires a supported kernel version of 3.4 or later, as listed in:
  • If you deploy the Cortex XDR agent on a Linux server that is not running one of the kernel versions required for these additional protection capabilities, the agent will operate in asynchronous mode: the agent will obtain a verdict for the executed ELF file in parallel to its execution and terminate it if a malware verdict is obtained. In addition, data collection for EDR and behavioral threat protection will not be supported.
  • In Cortex XDR agent 7.0.1 release deployed on endpoints running kernels RHEL, or CentOS, or Oracle 8, you must disable UEFI Secure Boot on the machine. Otherwise, the Cortex XDR agent will operate in asynchronous mode as explained above.
Software packages
  • ca-certificates
  • openssl 1.0.0 or a later release
  • Distributions with SELinux in enforcing or permissive mode:
  • Red Hat Enterprise Linux 6, CentOS 6, and Oracle Linux 6—policycoreutils-python
  • Red Hat Enterprise Linux 7, CentOS 7, and Oracle Linux 7—policycoreutils-python and selinux-policy-devel
  • SUSE—policycoreutils-python and selinux-policy-devel
  • Debian and Ubuntu—policycoreutils and selinux-policy-dev
  • glibc—Required for exploit protection of containerized processes using the ROP Mitigation and Brute Force Protection modules. If glibc is not installed, the modules are disabled but all other exploit and malware protection functionality work as expected.
