What is a network?
A computer network comprises two or more computers that are connected with the purpose of transmitting, exchanging, or sharing data and resources.

What about security?
More connected users and devices creates more complexity. Network security is crucial here are some reasons.
Data Breach
Organizations must make sure that their staff does not send sensitive information outside the network. Data loss prevention, or DLP, technologies can stop people from uploading, forwarding, or even printing critical information in an unsafe manner.
Malware
“Malware,” short for “malicious software,” includes viruses, worms, Trojans, ransomware, and spyware. Sometimes malware will infect a network but lie dormant for days or even weeks. The best antimalware programs not only scan for malware upon entry, but also continuously track files afterward to find anomalies, remove malware, and fix damage.
Access control
Not every user should have access to your network. To keep out potential attackers, you need to recognize each user and each device. Then you can enforce your security policies. You can block noncompliant endpoint devices or give them only limited access. This process is network access control (NAC).
Web security
A web security solution will control your staff’s web use, block web-based threats, and deny access to malicious websites. It will protect your web gateway on site or in the cloud. “Web security” also refers to the steps you take to protect your own website.

Network infrastracture
Network infrastructure refers to the hardware and software that enable network connectivity and communication between users, devices, apps, the internet, and more.
Benefits
Cost-effective
Network infrastructure requires little or no maintenance and can be used for years without needing replacement.
Reliable
Network infrastructure is built for performance, which means that your data will flow smoothly with little or no interruption. Set and expect a guaranteed service level for all users and customers.
Efficient
Network infrastructure allows you to connect many different devices at once, regardless of whether they’re in the same room or across the globe from each other.
Scalable
Network infrastructures can expand as needed to accommodate growing needs within your organisation’s network as well as access to and from external sources.
