What Network Security Types Are Available?

Network security is the collection of countermeasures that are put in place to protect your network and the data that passes through it. Network security is designed to protect the network from hacking attempts and employee negligence. Network security consists of three components: software, hardware, and cloud services.

Hardware appliances are servers and devices that provide security functions to the network environment. You can install hardware outside of the network traffic path, also known as "out-of-line," but more often it is installed inside the traffic path, called "in-line". The advantage of this is that in-line security appliances are able to stop data packets that have been flagged as potential threats, whereas out-of-line appliances simply monitor traffic and send alerts when they detect something malicious.

Antivirus software can be installed on devices or nodes in the network to enhance detection and threat mitigation.

Cloud services are the offloading of infrastructure to a cloud provider. This setup is similar to the way network traffic flows through in-line appliances. However, incoming traffic is directed to the cloud service. Before traffic is allowed onto your network, the cloud service scans and blocks potential threats.

A network security system that is effective uses multiple types of network security tools in order to build a layered defense system. Each layer provides threat identification and threat remediation capabilities, as well as active monitoring to ensure that the network is as secure as possible.
