What Is Network Security?
Every company, regardless of its size, must imply a level of network security in order to protect its valued data and the threats from the cyber world.
With the technological advancements on hand today, the architecture of the cyber world has become more complex and multifaceted that attackers are on a constant hunt for new and elaborate ways to misuse vulnerabilities. The mentioned vulnerabilities can exist in a multitude of areas, such as devices, data, applications, users, and locations. This is why there are numerous network security management tools and applications in place to tackle each individual area of threat and danger. Cyber threats are known to take down data and widespread chaos and damage, it is highly essential to input the necessary measure of protection.

How Does Network Security Work?
There are many facets to take into consideration when tackling the matter of network security across any organization. The presumed attacks can take place upon any layer or model; this is why network security should cover hardware and software to cover all areas.
Network security typically consists of three different areas of control; physical, technical, and administrative.
Physical Network Security
Physical network security helps to avert unauthorized access to physical network components, such as routers, cabling cupboards, and others. The controlled methods include locks, biometric authentications, and other devices that are found essential in all organizations.
Technical Network Security
Technical network security is in charge of protecting data stored on the network or that is in transit across, into, or out of the network. The protection in action within this method is two parts; it must protect the data and systems from unauthorized personnel access, and it also must guard against malicious actions from employees.
Administrative Network Security
Administrative network security contains security policies and methods to control user behavior. This includes the authentication of users, the level of access provided, and how IT staff members should imply changes to the infrastructure.
Types of Network Security
While we have talked about the different levels to implement network security, here are the various methods to secure the network.
Network Access Control
Comprehensive access control policies should be set in place for users and devices to prevent potential attackers from invading your network. For instance, administrators can gain full access to the network and deny access to certain confidential folders from other personnel.
Antivirus software helps protect an organization from a variety of malicious software trying to access the network; this includes viruses, ransomware, worms, and trojans.
Firewalls act as a barrier between trusted internal networks and untrusted external ones. Administrators usually configure a set of well-designed rules to block and permit traffic onto the network.
Virtual Private Networks
Virtual private networks help create a connection between the network and another endpoint or site. For instance, users from home can connect to the organization’s network over a VPN. The data between the two points is encrypted for security reasons, and the user will need to authenticate to allow communication between their device and the network.
