Pre-installation requirements

Before installing the Forcepoint DLP Protector software, you have to ensure the requirements are met.

• Forcepoint DLP Protector software package is supported on CentOS 7.6 or CentOS 7.9, or on RHEL 7.5, RHEL 7.6, RHEL 7.7, RHEL 7.8, RHEL 7.9, or RHEL 8.
  Note:

  • General Availability (GA) versions of Red Hat Enterprise Linux (RHEL) 8 require a license key upon installation. This key is available for purchase through Red Hat's official channels.
  • This RHEL8 release does not support the following features:
    • Microsoft RMS Decryption
    • Forcepoint DLP REST API
• For software package deployment, verify that the outputs of the two commands match:

  "hostname -f": --fqdn, --long long host name (FQDN)

  "hostname -s": --short short host name

  If the outputs match, continue the installation.

  If the outputs do not match, the FQDN (long) should be changed to match the short hostname.

  To change the FQDN:

  1. Open the hosts file located in /etc/hosts as root.
  2. Add the following entry to the hosts file:

     <Protector IP address> <New Hostname> (match to the short hostname, hostname -s)

     

• At least two network interface cards are required.
• For hardware requirements, see Protector Hardware Requirements.
• The file system where /opt directory resides must have a minimum of 45GB disk space.
• SELinux must be disabled before the software protector installation.
• The installation will check whether firewalld or NetworkManager are running and disable them if they are running.
