Importance of cyber security in our daily life

In today's digital age we are all constantly dependent on the internet and technology in one way or another. We use a variety of electronic devices and the Internet to exchange information in our daily lives. Taking advantage of that opportunity, some unscrupulous groups carry out various cyber crimes with the help of a network or internet and an electronic device.

With the advancement of technology, violence, and cybercrime are increasing day by day. Here are some common cyber crimes:

1. Email and internet fraud

2. Identity Fraud (where personal information is stolen and used)

3. Theft of financial or card payment data

4. Theft and sale of corporate information

5. Cyber ​​Extraction (demanding money to prevent threatening attacks)

6. Ransomware attack (a kind of cyber extraction)

7. Hacking a computer or device

8. Data loss by entering the system illegally

9. Data theft

10. Various other Malicious attacks & Network hacking etc.

Many more types of cybercrime are being organized through the internet and technology. But that does not stop the pace of our lives. We need cyber security so that we can use the internet and technology while protecting our personal information, data, etc.

That is why we need to have good knowledge about cyber security. Today we will discuss in detail cyber security

What is cyber security?

The activities that provide information and network security in the digital world are cyber security, that is, cyber security is part of the process and practice of using technology to protect networks, devices, programs, and information, and to protect against various types of cyber attacks. Protects against data theft and illegal entry into the system. We store our necessary information, confidential files, documents, etc. on our computer. And when the Internet is used in that computer, it becomes connected to a huge network. 

A hacker can then enter your computer through this network and steal or destroy important data and files. Cyber ​​security can protect your device and network across the Internet.

How cyber security works?

Cyber ​​security is a very important process for us. Cyber ​​security protects the various important information, programs, etc. in our computers from cyber attacks. There are Cyber ​​Security Expert teams or organizations to provide cyber security services. Those who use different types of programs, software or hardware, etc. add some layers of protection between our computers, devices, networks, etc. By adding these layers of protection, our Networks, Computer systems, programs, Data/servers, etc. are protected and hackers cannot do any kind of hacking.

In this process, the problems and vulnerabilities of a computer system are discovered and the system is protected from Security Violations.

Types of cyber attacks

Cyber ​​attacks come in all shapes and sizes. There may be some open ransomware attacks (snatching important business products or equipment for ransom to release them), and some covert operations through which criminals infiltrate a system to obtain valuable data that can be discovered months after it became true. Criminals are becoming more tactful with their malicious activities and there are some basic types of cyber attacks that affect thousands of people every day.


Malware is used to describe malicious software including spyware, ransomware, and viruses. It usually breaches networks through a vulnerability, such as clicking on suspicious email links or installing a risky application. Once inside a network, malware can get sensitive information, create more malicious software throughout the system, and even block access to important business network elements (ransomware).


Phishing is the practice of sending malicious communications (usually emails) that are designed to show from reputable, well-known sources. These emails use the same name, logo, words, etc. as a CEO or company to dispel suspicions and get victims to click on malicious links. Once the phishing link is clicked, cybercriminals have access to sensitive data such as credit cards, social security, or login information.

Social engineer

Social engineering is the process of psychologically manipulating people to reveal personal information. Phishing is a form of social engineering where criminals take advantage of people's natural curiosity or beliefs. An example of a more advanced social engineering is voice manipulation. In this case, cybercriminals take a person's voice (from sources such as voicemail or social media posts) and use it to call friends or relatives and ask for a credit card or other personal information.

Man-in-the-middle attack

Man-in-the-middle (MitM) attacks occur when criminals obstruct traffic between two-way transactions. For example, criminals can insert themselves between a public Wi-Fi and a person's device. Without a secure Wi-Fi connection, cybercriminals can sometimes see all the victim's information without being caught.

Zero-day attack

Zero-day attacks are becoming more common. Basically, these attacks occur between declaring a network vulnerability and resolving a patch. In the name of transparency and security, most companies will declare that they have found a problem with their network security, but some criminals will take this opportunity to launch an attack before the company can come up with a security patch.

Why cyber security is important

1. Cyber ​​security is required to protect the files, data, information, etc. stored in the computer from various types of cyber attacks. 

2. The number of hackers or cyber criminals is currently increasing. Cyber ​​security is important to keep the information stored in their devices safe from various cyber crimes organized by them.

3. Cyber ​​security is essential to protect the banking and various financial sectors from cybercriminals.

4. Cyber ​​Security The role of cyber security is essential in protecting the country's defense system.

Various types of information are stored on current computers in government and private offices. Which is very likely to be hacked by hackers. Therefore, cyber security is needed to protect the information of various companies from being leaked in government offices.

What are the types of cyber security?

Cyber ​​security provides services to users based on different types of security issues in different digital environments.

Types of cyber security have been divided into 6 categories to prevent various types of cyber crimes.

1. Network and Gateway Security

2. Application Security

3. Data Loss Prevention (DLP)

4. Email Security

5. Network Access Control (NAC)

6. Antivirus Security

Such as URL filtering application control, data theft prevention, antivirus, and HTTPS inspection.

Application Security

Application Security protects different types of applications used in the network from various types of cyber attacks through a security process.

If an application encounters an error that exposes it to the system as a security threat.

Data Loss Prevention (DLP)

Microsoft Endpoint Data Loss Protection Now Commercially Released -

This process encodes the user's data and protects it from various types of cyber attacks. As a result, there is no fear of data theft.

Email Security

We noticed that we have a Spam Folder in Gmail. Because the email security system is connected to the network, any type of cyber threat that is a risk to email cyber information goes directly to the Spam Folder.

Network Access Control (NAC)

Network access control is the process of keeping unfamiliar and unauthorized users and devices out of a private network. Companies that occasionally allow certain devices or users from outside the company to access the network may use the network access control to ensure that these devices comply with corporate security compliance rules.

One advantage of network access control is that users may need multi-factor authentication, which is much more secure than identifying users based on a combination of IP address or username and password.

Antivirus Security

Antivirus is a type of software used to prevent, scan, detect and delete viruses from a computer. Once installed, most antivirus software automatically plays a role in providing real-time protection against virus attacks.

Antivirus protection programs help protect your files and hardware from malware such as worms, Trojan horses, and spyware and provide additional protection such as customizable firewalls and website blocking.

So it is very important for everyone to have antivirus software on their computer.

The benefits and advantages of cyber security

Protecting important data and information from hacking. Any device can attack a variety of threats. For example viruses, Spyware, Worms, Adware, etc. You can avoid the damage caused by viruses and Malware.

Online transactions can be done in a secure way.

Network security is provided and unauthorized users or threats are not allowed to enter the network.


Cyber security is very important for the present time. Without cyber security, we would be constantly confused about data, information, etc.

As a result of using cyber security, we get the above benefits. As a result, we do not have the fear of data theft, hacking, etc.
