Network security’s primordial goal is basically securing your network. Networks can be private, like a network within a company, or public. Thus, ensuring 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 about them. Without this authentication, no user is permitted to access the network. The network administrator handles overseeing the network’s operation.

Network Security covers various applications, including devices, processes, and technology. To put it in the most basic terms, it implies a set of rules and regulations employing software and hardware technologies to safeguard the fundamental principles of cyber security - Confidentiality, Integrity, and Accessibility. Regardless of size and structure, every organization’s network security must cut across several sectors. The principal motive is to secure the organization.

What is Network Security?

Network security consists of the steps by any business organization to protect its digital network perimeter by utilizing both hardware and software technologies. This is done to ensure the data’s and network’s anonymity and transparency. Every company or organization that processes a substantial volume of data has some level of protection against various cybersecurity threats.

Network security solutions defend computer networks from a variety of threats, including:

  • Users
  • Addresses
  • Information
  • Devices
  • Utilization

Advantages and Disadvantages of Network Security

To access data relevant to them, each user is given a unique user ID and password. No user is allowed to enter the network without this authentication. The network administrator is in charge of the network’s operations. As with any technical area, Network Security has advantages and disadvantages. We will learn all about them today here in this post.

Advantages

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.

Centrally controlled

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

Prevents cyber attack

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

Levels of access

The security software gives different levels of access to other users. The user’s authentication is followed by the authorization technique, checking whether the user is authorized to access specific resources. You may have seen certain shared documents password protected for security. The software knows which resources are accessible by whom.

Careless admin

When the best software is installed and everything required is done, it is natural for the admin to be careless sometimes. It is his job to check the logs regularly to check the malicious users. But sometimes, he trusts the system, which is when the attack happens. So, the admin must remain vigilant always.

Disadvantages

Costly setup

The setup 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, security, being of prime importance, will 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 several sample passwords before one is finalized, which takes a lot of time.

Requires skilled staff

Managing large networks is not an easy task. It requires highly skilled technicians who can handle any security issue that arises. A network administrator must be employed to ensure the smooth working of the network. He must 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 sometimes. His job is to check the logs regularly to check the malicious users. But sometimes, he trusts the system, which is when the attack happens. So, the admin must remain vigilant always.

How Does Network Security Work?

Whenever it comes to network security in a company, there are several layers to evaluate. Because breaches can occur at any tier of the network security layers architecture, your network security devices, application, and rules must be built to cover all bases.

Physical, technological, and implementation of controls are the most common types of network security measures. Here’s a rundown of the many forms of network security and how each regulation operates.

Physical Network Security

Physical security measures prevent unauthorized individuals from physically accessing network components such as gateways, cabling cabinets, etc. Locks, authentication systems, and other technologies that control access are crucial in every company.

Technical Network Security

Data is stored on networking or in transport across, into, or out of the network and is protected by technical security mechanisms. Protection must be twofold: safeguarding data and systems from unauthorized persons while protecting against harmful employee activity.

Administrative Network Security

Administrative security mechanisms are protection rules and regulations that underlie user behaviour, such as how users are verified, their degree of access, and how IT staff members make network modifications.

Network security is vital in protecting customer information and data. Besides, It secures shared storage, protects against viruses and improves the network’s performance by lowering unnecessary expenses and costly setbacks from data breaches. Furthermore, it ensures there will be less break time from unauthorized attackers or viruses. It can save companies money in the long run.
