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 Red Hat Enterprise Linux 7.5 to 7.9 and Red Hat Enterprise Linux 8 versions.
  Note:

  • Use of Red Hat Enterprise Linux 8 requires a license key upon installation. Subscriber must separately purchase a license key to Red Hat Enterprise Linux 8 through Red Hat’s official channels.
  • This Red Hat Enterprise Linux 8 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, you can continue the installation.

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

  To change the FQDN, you must open the hosts file located in /etc/hosts as root and 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.
