Modify Security Settings

The default Red Hat firewall settings cause issues with SecurityCenter’s web services. To easily alleviate this, SELinux must be either set to Disabled or enabled in Permissive mode. You can disable SELinux Enforcing mode using the following steps:

  1. Navigate to: /etc/selinux
  2. Edit the file named “config”.
  3. Change the SELINUX line from “SELINUX=enforcing” to “SELINUX=disabled” or “SELINUX=permissive”.
  4. Save the file.
  5. Reboot the system.

Ensure the following incoming services are permitted by the firewall rules:

  • SSH (port 22 by default)
  • HTTPS (port 443 by default)

Note: Please consult local security and best practices within your environment for the proper usage and configuration of SELinux. SecurityCenter is known to work with SELinux in Enforcing mode with some customization of the SELinux rules. However, permitted rules vary from organization to organization.
