What is Network Security?

Network security refers to the different countermeasures that you can use to protect your network and the data stored on the network or the data that passes through it. It is more of a proactive measure that keeps the network safe from cyberattacks, negligence, hacking attempts and many other consequences.


There are three components of network security


  1. Software
    The Software component of Network Security includes antivirus and related applications, network security software and software that you can install on devices and nodes across the network. These can be quite helpful to provide added detection and threat remediation.

  2. Hardware
    Hardware appliances include servers or devices capable of performing different security functions within the networking environment. You can install these hardware components out of the path of network traffic which is called “out-of-line. But it is installed in the path of traffic or in other words, these exist “in-line”. This is really helpful if in-line security appliances are capable to stop data packets that are flagged as potential threats. Whereas when we talk about out-of-line appliances, they simply keep an eye on the traffic and send notifications when they detect a malicious file or object.

  3. Cloud Services
    Cloud services can be referred to as offloading the infrastructure to a cloud provider. The set-up is generally according to the network traffic that passes through in-line hardware appliances. But the incoming traffic is redirected to cloud services. The cloud services aspect of networking. It doesn’t perform any kind of scanning and blocking of potential threats before it is allowed to pass through and enter your network.

A good network security system is a combination of different types of network security tools. These tools create a layered defense system and the theory behind this is that if a threat manages to slip through a security countermeasure, the other layers can still be able to prevent the damage from entering your network.


Each network security layer performs the following function:

  • Identification
  • Monitoring
  • Threat remediation
  • Keeping the network secure

Network Security Devices and Tools


There are  a few network security tools that you can incorporate in your business include:


Antivirus Software
Malware is one of the common forms of cyberattack that come in many different shapes and can consume a lot of space on your system.

Access Control
This refers to keeping a check on places and people who can access a particular piece of information or sections of your computer or network. You can get this done by using security policies and granting access to the network or folders to users and devices who are required to access that resource.


Behavioral Analytics
This is quite helpful for users to identify any abnormal behavior. The security support individuals should establish a baseline about the normal behavior of a customer or a user, network and applications. There are different behavioral analytics software that can help you identify common indicators that point towards abnormal behavior and avoid security breaches.


Apart from that, you can also benefit using data loss prevention or DLPs, Distributed Denial of Service prevention, Email security, Firewalls, and other network security measures and make sure that you keep your network secure. As our world has become more digitized, we rely more on the Internet and networks to store data and get done with many tasks. So having a secure network is more than necessary for both individuals and businesses to get things done in a more secure and streamlined way.
