System Requirements for Ransomware Protection

Verify that your environment meets the system requirements.

Operating System

The following operating systems are supported:

  • AlmaLinux 8.x
  • Oracle Enterprise Linux 7.x
  • Oracle Enterprise Linux 8.x
  • Oracle Enterprise Linux 9.x
  • RHEL 7.6 to 7.9, RHEL 9 and RHEL 9.2, and their corresponding CentOS release
  • RHEL 8.0 to 8.8 (Python 3.6), and their corresponding CentOS release
  • Rocky Linux 8.x
  • Ubuntu 20.04

Programming Language

Python 2.7

Customized SELinux Module

If you already customized the SELinux module that is present on a Linux MediaAgent, then you cannot use the ransomware protection feature.

Packages

Note

For RHEL8, install python3-libselinux instead.

  • policycoreutils-devel
  • psutil
  • selinux-policy
  • selinux-policy-devel
  • selinux-policy-targeted

To verify the presence of the above packages in your environment, execute the following command:

#rpm -qa | egrep 'libselinux-python|policycoreutils-devel|psutil|selinux-policy|selinux-policy-devel|selinux-policy-targeted|python3-libselinux'

For a HyperScale MediaAgent, you must upgrade the operating system to install the above packages. For more information about installing operating system updates on HyperScale, see related documentation:

Packages for $} on Ubuntu 20.04

  • selinux-utils
  • selinux-basics
  • selinux-policy-dev
  • python3-selinux

Execute the following command to install the packages:
