Advantages and Disadvantages of Network Security

We live in a digital world. And it has truly transformed our lives in more ways than one. But with the growing popularity of digitalization, it has become very important to ensure safety. More importantly, network security is the need of the hour. So here’s a look at the advantages and disadvantages of network security.

What is Network Security?

Network security is basically securing your network. Networks can be private, like a network within a company, or the public. Securing the network involves preventing any misuse or unauthorized access of the network or its resources. For this, every user is given a unique user ID and password to access data pertaining to them. Without this authentication, no user is permitted to access the network. The network administrator oversees the operations of the network. This is most commonly involved in businesses, organizations, and other kinds of institutions. Network security works under the concept of confidentiality, integrity, and availability. With the increase in cybercrimes across nations, it has certainly become very important for organizations to be vigilant against criminals.

Advantages and Disadvantages of Network Security

Advantages of Network Security

Protect data

As discussed, network security keeps a check on unauthorized access. A network contains a lot of confidential data like personal client data. Anybody who breaks into the network may hamper these sensitive data. So, network security should be there in place to protect them.

Prevents cyber attack

Most of the attack on the network comes from the internet. There are hackers who are experts in this and then there are virus attacks. If careless, they can play with a lot of information available in the network. The network security can prevent these attacks from harming the computers.

Levels of access

The security software gives different levels of access to different users. The authentication of the user is followed by the authorization technique where it is checked whether the user is authorized to access certain resources. You may have seen certain shared documents password protected for security. The software clearly knows which resources are accessible by whom.

Centrally controlled

Unlike the desktop security software, the network security software is controlled by a central user called network administrator. While the former is prone to worms and virus attacks, the latter can prevent the hackers before they damage anything. This is because the software is installed in a machine having no internet.

Centralized updates

It is very important that the anti-virus software is timely updated. An old version may not offer you enough security against attackers. But it is not guaranteed that every user of the network follows it religiously. A network security system that is centralized offers this advantage of timely updates without even the knowledge of the individuals.

Disadvantages of Network Security

Network security is a real boon to the users to ensure the security of their data. While it has many advantages, it has some disadvantages as well. So let us discuss some of them.

Costly setup

The set up of a network security system can be a bit expensive. Purchasing the software, installing it, etc can become costly especially for smaller networks. Here we are not talking about a single computer, but a network of computers storing massive data. So, the security being of prime importance will definitely cost more. It cannot be ignored at any cost!

Time-consuming

The software installed on some networks is difficult to work with. It needs authentication using two passwords to ensure double security which has to be entered every time you edit a document. It also requires the passwords to be unique with numbers, special characters, and alphabets. The user may have to type a number of sample passwords before one is finalized which takes a lot of time.

Advantages and Disadvantages of Network Security

Requires skilled staff

To manage large networks is not an easy task. It requires highly skilled technicians who can handle any security issue that arises. A network administrator needs to be employed to ensure the smooth working of the network. He must also be trained adequately to meet the requirement.

Careless admin

When the best software is installed and everything required is done, it is natural for the admin to be careless at times. It is his job to check the logs regularly to keep a check on the malicious users. But sometimes, he just trusts the system and that is when the attack happens. So, it is very important that the admin remains vigilant always.
