Network Security/ What are the types of network security?

Hello Friends, In this blog post, I am going to let you know about Network security, which is an essential part of networking. In older times when the computer networks come into its existence usually, researchers used them for sending emails or there are broadcasts.

Inside this blog post, we are going to explore What are the types of network security? Why is Network Security? What are the 3 types of security? What are the 4 types of networks?

The question of network security does not arise then. Later when ordinary people started using the network for banking, shopping, and filing a tax return; through interconnected computerized systems, demands for secrecy gradually crept in.

Nowadays when organizations and individuals depend more on the data available to make critical decisions, the authenticity of data is sure to be maintained with validated network security.

At the same time, privacy is the right of an individual to get protection against damage caused by inaccurate and inappropriately released data, it is the job of network security to provide protection within the information system.

Network Security covers a broad topic, mainly it concerns unauthorized entry but also deals with the problem of the legitimate message being captured and replayed and when people trying to deny that they had sent the certain message.

The element from which protection against unauthorized entry is to be made, includes students, professional teachers, businessmen, ex-employers, spies, and terrorists. Network security problems can be roughly divided into four integrated areas.


It has to do with keeping information out of the hands of unauthorized users and minimizing the probability of intrusion.


It deals with determining who you are talking to before revealing sensitive information or doing any business deal.


It deals with a signature so that nobody can deny afterward a placed or supplied order.

Integrity control:

This is to maintain the integrity of sent data so that the same meaning of the message is conveyed as the sender meant. There are various methods to achieve network security. One such method is cryptography.

What are the types of network security?

Network security is divided into further segments and they are described below.

Email security
Distributed denial of service prevention
Data loss prevention
behavioral analytics
Access control
Anti-virus and anti-malware software
Application security

What are the security principles?

There are some basic principles in the network security that should be followed in order to make a secure network:

Data integrity: data in the network must be secure, accurate, and reliable.
Data Confidentiality: Data information over the network should be secret and secure.
Availability of the data.
Keystroke monitoring.
Password protection.
Protecting audit data.

Why is Network Security?

Network security has been an essential parameter in today’s time. Network security is required in both places home networks and office networks or business environments.

What are the 3 types of security?

Mainly there are three types of areas in network security which are management security, operational security, and physical security control.

What are the 4 types of networks?

The four types of networks are defined as LAN(Local area network), MAN(Metropolitan area network), WAN(wide area network), and PAN(personal area network).

What are the 4 types of cyber attacks?

Malware: defined as suspicious software and malicious software such as spyware, virus, worms, and ransomware.

What are the two types of security?

Security broadly can be classified into two categories like equities, and debts.
