Network security, a subset of cybersecurity, aims to protect any data that is being sent through devices in your network to ensure that the information is not changed or intercepted. The role of network security is to protect the organization’s IT infrastructure from all types of cyber threats including: Viruses, worms and Trojan horses.

Network security vs. app security: ... the network has no boundaries… enable them for Internet access, there are other points of vulnerability injected into that overall picture,” Ledingham ...

Organizations can place routers between networks to create boundaries, increase the number of broadcast domains, and effectively filter users’ broadcast traffic. Organizations can use these boundaries to contain security breaches by restricting traffic to separate segments and can even shut down segments of the network during an intrusion, restricting adversary access.

Figure 5 – 17: Security Zones. Server and external traffic isolation. A security zone is nothing more than a network segment with protected ingress. The level of protection is commensurate with the criticality of systems or the sensitivity of data it contains. One type of security zone provides a secure bridge between the internet and the data center.

Network security is an organization’s strategy that enables guaranteeing the security of its assets including all network traffic. It includes both software and hardware technologies. Access to the network is managed by effective network security, which targets a wide range of threats and then arrests them from spreading or entering in the network.

There are three main benefits of network segmentation. First is security. It reduces your attack surface and limits lateral movement in the event of a breach. Second, you can improve network performance, as traffic will be confined to the part of the network where it is required.

With a firewall/NAT device between the internal network and the internet, the security zones are clearly forming. There is the internal “secure” zone, the DMZ (demilitarized zone), and the untrusted zone (aka the internet).

In 4G, there is a clear distinction between the network core (which processes the data) and the edge (which allows for cellular user connectivity). In 5G, these two operations will be intertwined and supported by virtualized components with software from multiple vendors at the same time (and potentially from different countries), which might significantly affect the overall security posture.

Data crossing a trust boundary also means that you have identified a place where you should examine the security of the data. It doesn't mean you must encrypt or that you must authenticate, but as you analyze the connection for vulnerabilities, you may discover that encryption and/or authentication remediates the issues.
