In today’s world, the internet says that computers came and computers said that the computer network had also come and with this computer network comes another name, security. network security is important and necessary.
So in today’s blog we are going to learn about the computer network security, so let’s move on to learning security.
1. What is a Computer Network:
Learning About Network Security First, let’s learn about computer networks first because there will be many newbies who will be hearing about it all for the first time.
“Two or more computers connected together to share data and information or a file is called a computer network”.
2.What is Computer Network Security:
“Computer network security is the process of protecting and accessing data on your computer network system”.
* Example: Suppose we have created a computer network for “A” city company and its second branch is in “B” city, then from “A” city it has to deliver data to B city, but it is safe and there is a thief (hacker) in between who can steal your data and misuse it. For that, “A” company encrypts the data and sends it to “B” company, so its authority is only with “B” company, and it can read the data, and even if it falls into the hands of a hacker, it will not be able to read the data and file. This the thief does not have his authority, this is called “computer network security”.
3. Computer Network attack history:
In today’s world, cyberattacks happen every day, but after this world’s first network attack, security had to be improved.
1962 The modern history of cyber crime begins when Allen Scherr (MIT) cyber attacked computer networks by stealing passwords from their databases using punch cards.
Then, in 1971, Bob Thomas at BBN Technology introduced the first computer virus for research purposes.
4. Computer Security Tools:
Below are the some network security tools that will provide you with security in your computer network system:
A. Firewalls:
A firewall is a network security system that restricts Internet traffic to or from a private network.
B. Antivirus software:
Antivirus software helps you detect, block and remove viruses and malware from your computer and other (IT) systems.
C. VPN:
VPN security tools are used to authenticate communications between secure networks and end point devices (VPNs) over virtual private networks.
5. How to work computer network security?:
How is network security done? You must have asked this question. Don’t worry, I will tell you. This security is done through the following four steps:
A. Secure:
In the first step, the network is secured such that each (authorized person) is given a (username) and (password) that is used by an authentic person. From which only the authorized person can access the network. (Firewall Antivirus) is also used to prevent viruses and malware in the network.
B. Monitor:
In the second stage, some errors in the computer monitor network are examined again.
C. Test:
In the third phase, the network is checked to see whether everything is working well or not.
(
D. Improve:
In the fourth phase, the security of the network is improved so that the network can be more secure.
6. Conclusion:
“So that’s all for today’s topic, so that you have learned and understood a lot about computer network security. See you in the next blog till then, take care, improve tech knowledge”.
