Run firewall-cmd commands on both nodes, and allow traffic for Pacemaker (TCP ports 2224, 3121, 21064, and UDP port 5405): sudo firewall-cmd --permanent --add-service=high-availability. sudo firewall-cmd --reload. Install the Apache HTTP server on both nodes, and open the HTTP ports in the firewall: sudo yum install -y httpd.

This is filtering provided at the network edge by a firewall with rules (ACLs) restricting what internal users are allowed to access. Some firewalls have the ability to filter by an application (layer 7 firewalls), but we’re going to concentrate on standard packet-filtering firewalls and their capabilities.

For internal vulnerability scanning, you can set up an OpenVAS server running on Linux. There is no licensing cost for Linux or OpenVAS, which is a bonus. If you’re interested in learning more about vulnerability scanning, it’s covered in Linux Academy’s CompTIA Pentest+ course here.

The Linux Audit system is a great solution. Your security team can use the Linux Unified Key Setup (LUKS) to encrypt and decrypt physical disks to keep data secure when not in use. OpenSCAP shows that a firewall is installed and running, that the Telnet protocol is disabled, and so on. Stay Compliant with Linux Academy.

These policies, like any firewall, provide an invaluable means of limiting attack vectors both inside and outside the VPC. It is important to remember that just because an endpoint is behind a firewall doesn’t mean it is not a vulnerability. These suggestions and others are covered in Linux Academy’s Kubernetes Security Course.

Think about all the controls we have in place on our networks today: firewalls, authentication systems, intrusion detection and prevention systems (network- and host-based), router and switch security, operating system security, data encryption — the list goes on and on. It’s in this domain that we lump the following: Firewalls.
