Before you install the
Cyber Recovery software and the Docker components, ensure that mandatory access control settings are configured appropriately for your environment.
About this task
For a
Cyber Recovery software installation, we recommend using SELinux as the Linux Security Module for added operating system security. Because SELinux provides granular access control, be careful when configuring security contexts for
Cyber Recovery files and directories. Use of SELinux does not apply to a
Cyber Recovery virtual appliance deployment.
By default, the AppArmor application is installed in a
Cyber Recovery virtual appliance deployment as mandatory access control mechanism. The
Cyber Recovery software applies a customized AppArmor policy to the
Cyber Recovery Docker container services to provide compatibility and added security benefits.
Steps
Log in to the
Cyber Recovery host in the
Cyber Recovery vault.
For a
Cyber Recovery software installation only, enable SELinux.
Install the Docker components.
Install the
Cyber Recovery software (see the
Dell PowerProtect Cyber Recovery Installation Guide).
In an SELinux environment, if the
Cyber Recovery software does not start after a reboot due to unlabeled context type and custom policies, do the following:
