This approach greatly simplifies their automation, making it easier to enforce good network security.

For example, deployment of branch office networks would be specified by a single network design that includes details like device hardware, operating systems, and interfaces are used for each network link. (There is one policy that isn’t reflected in device configurations: minimizing variations in network design. The automation system helps deploy and maintain the configurations that reflect your policies. These policies range from simple things that are not security related, like device naming standards, to essential security policies like authentication controls and access control lists. Once each device on the network is discovered, the automation system downloads its configurations and checks them against the configuration rules that implement your network policies. A router that’s forgotten and left unsecured could be the avenue that bad actors exploit. Stated differently, the goal of automation is to guarantee that your network policies are consistently applied across the entire network.

Gartner: IT skills shortage hobbles cloud, edge, automation growthĪutomating the processes of device discovery and configuration validation allows you to enforce good network security by making sure that your devices and configurations not accidentally leaving any security holes open. Automation is the technology that allows you to build repeatable processes to validate and enforce your network policies. You need the right people with the right skills and the ability to do effective work, good policies and processes, and the right technology to make it happen. Sound network-device security practicesĮffective network operations depend on the triad of people, process, and technology. Here’s a look at how automation should be used to enhance network security. IDS, IPS, SASE, and other newer technologies get a lot more attention, but automation is critical to modern network security. The recent T-Mobile data breach, reportedly facilitated by attackers gaining access to an unprotected router and from there into the network, could have been prevented through the use of network automation.
