In this regard, network security encompasses both hardware and software systems that are designed to do just that. It also includes processes and procedures that are put into place to monitor and address any issues.

For example, it may involve the use of firewalls to limit access to specific applications or to specific users. Another example is the use of encryption to ensure that communications are secure. Other protocols like QUIC (“Quick UDP Internet Connections”), IP (“Internet Protocol”), ICMP (“Internet Control Message Protocol”) and IPSec (Internet Protocol Security) are used to provide additional protections by creating secure, encrypted connections between network devices.

Another critical component of network security involves the physical protection of devices, servers and other equipment that comprise the system. This is known as endpoint security and it applies to things like laptops, tablets and phones, as well as “Internet of Things” devices such as smart thermostats, refrigerators, front door locks and light bulbs.
