If you want to know what is Cybersecurity, its Definition, how it works, and what are its types. If you know, then you may not know everything, then after reading this article properly, you will know the full information.
What is Cybersecurity
Cybersecurity is a type of security that is a security for systems connected to the Internet. Through this, the data of hardware and software is made more secure so that the data is not stolen in any way and all documents and files are safe.
Cybersecurity is made up of two words Cyber + Security, meaning whatever is related to Internet, Information, Technology, Computer, Network, Application or Data, we call it Cyber.
Whereas security is related to security which includes System Security, Network Security, Application and Information Security.
How Cybersecurity Works
Under Cybersecurity, there is a large team of Ethical Hackers who protect your data from theft, data deletion or damage to any of your devices. Those working in Cybersecurity prevent bad people from doing wrong things.
Under this, your network, computer system, any program and your data are kept secure.
Why Cybersecurity is Important
- Cybersecurity is necessary to keep our personal data such as images, PDFs, Text Documents, or any other type of data that resides on our computers safe.
- Cybersecurity is very important to keep any such data of ours, in which only our copyright is safe. For example, if you have a company, only you have copyright on its data, then it is necessary for no one to steal it or no other person can use it.
Cybersecurity is also very important to provide security to our Banking and Financial data because if our banking data is not secure then any hacker can withdraw money from our bank account. And nowadays, Internet banking has become an essential part of life, that is why it is important to keep banking and financial data safe.
Cybersecurity is also very important for national security. National Security means that nowadays there are cyberattacks on the defense system of our country too.
- There is also some such data or information which is very necessary and sensitive, as nowadays most of the work in government offices is also done through the internet.
If the data of any government office gets leaked, then it can cause a lot of damage. Therefore, cybersecurity is also very important to keep this type of data safe.
Types of Cyber Crime
1. Hacking
In this type of cybercrime, hackers enter the restricted area and access the personal data and sensitive information of another person, without the permission of that person, the restricted area is someone's personal computer (PC), mobile, or any online. There can be a bank account (Net Banking).
2. Cyber Theft
In this type of cybercrime the hacker violates any copyright law, it is a part of cybercrime which means theft done through a computer or the internet. This includes identity theft, password theft, information theft, internet time theft, etc.
3. Cyberstalking
This Cyber Crime is more visible on social media sites. In this, stalkers harass and harass a person by repeatedly sending dirty messages or emails.
In this, stalkers often make victims of small children and people who do not have much knowledge of the internet. After this, stalkers start blackmailing that person, due to which the life of the person becomes very painful.
4. Identity Theft
This type of cybercrime is seen a lot these days. In this, hackers target those people who use online cash transactions and banking services like Google Pay, Phonepe, and Paytm.
Hackers take away all the money from a person by obtaining personal data such as account numbers, debit card details, internet banking details, etc.
5. Malicious Software
Much such dangerous software is created by hackers, so they can not only steal the data of any computer or mobile connected to the internet but can also delete it, as well as with the help of these software programs, hackers can make your entire system crash
These software programs are of many types such as Malware, Spyware, Viruses, Ransomware, and worm. Hackers send this type of software mostly through a link, pop-up message, or email to another computer and ask to touch the link in tempting ways.
If that person touches on the link, then the complete control of the computer goes into the hands of the hacker.
6. Phishing
In this type of Cyber Threat, the hacker sends a message or email to a person in the form of a trusted institution or bank, which looks valid on seeing. The purpose of the hacker behind this is to cause financial harm to that person by taking sensitive information like bank account number, debit card, Aadhar card, etc.
7. Child Pornography and Abuse
In this type of cybercrime, hackers mostly use chat rooms and talk with courtesy by hiding their identity.
Small children or minors do not have much information, and gradually hackers obstruct children from child pornography. Apart from this, children are not able to tell anything to their parents due to fear.
8. Man in the Middle (MITM) Attack
In this type of cybercrime, the attacker who is the hacker keeps on spying on the communication of two people and after some time becomes one of those two people and is necessary from the front. Information, and sensitive data like the bank, debit, credit card details, etc. Due to this, the person in front does not even know and the hacker gets all the information.
9. Denial of Services (DoS)
The main purpose of a DoS attack is to reduce the traffic of a network or website. In this attack, hackers weaken the network system by suddenly bringing a lot of traffic to a network or website.
Along with this, there are many services like Email, Yahoo, Hotmail, etc. When suddenly there will be a lot of traffic in these, then if any user goes to log in, the user will not be able to use that service.
10. Spoofing
In this type of cyberattack, the hacker can attack the system of a big server or big company by using the identity of another person. By taking the help of this attack, a hacker can ruin someone's life.
11. Salami Slicing Attack
"Salami Slicing Attack" is also called "Salami Fraud". In such cyber crime, cyber criminals carry out a big attack by doing many small attacks. Attackers use customer information such as bank/debit card details to deduct very small amounts of money.
Due to the small amount of money being deducted, customers remain unaware of slicing and do not even complain about it, due to which the hacker cannot be detected. It is just a strategy to profit from small increments from time to time.
Apart from these, there are many other cyberattacks, with the passage of time, new types of them are also being discovered.
Types of Cybersecurity
In Cybersecurity, different security is provided to the user in different layers of the network. All the crimes mentioned above are done online and the 6 best cybersecurity to prevent them are as follows-
1. Network & Gateway Security
This can be called the first layer of the network. You must have heard the name of Firewall in Computer. This is a wall for a network that allows only secure things to enter and keeps unsafe threads out.
2. Data Loss Prevention (DLP)
In this process, all the data of the user is fully encoded, in which SSL (Secure Sockets Layer) is used. Under this protection, the information or data is encrypted to keep it away from Unauthorized Access.
3. Application Security
By this, the applications being used in the network are passed through a security process. So that the shortcomings of that application can be removed. Also, if that application is insecure, then it is taken out of the network.
4. Email Security
If you use Gmail, you must have noticed that some emails go into the Spam folder. This happens because Spam Filters are installed in the network for Email Security. So that harmful emails can be kept away from the reach of the user because most of the crime is done through Email Phishing.
5. Antivirus Security
Everyone keeps Antivirus installed in their computer. It protects our computer from different types of Viruses. After all, all our sensitive information and private files are stored in the computer itself, that is why it is very important to keep it safe.
6. Network Access Control
By this, the work of keeping unauthorized users and devices out of the network is done. NAC protects the functionality of the network, ensuring that only authorized users and devices have access to it. Network operators decide which devices or applications comply with endpoint security requirements and whether or not they will be allowed network access.
Benefits of Cybersecurity
- With the help of this, we can stay safe from Unauthorized Access, so that there will be no risk of any kind of data loss.
- With the help of Cybersecurity, we can keep our network secure, so that we can use the Internet with confidence.
- A security cover is provided to your personal and sensitive data so that hackers cannot exploit you financially or mentally.
- Information security is improved and business management also increases.
- Nowadays, online cash transaction is very much in vogue, so you can do secure transactions with cybersecurity.
Conclusion What is Cybersecurity? Just knowing is not enough. The best way to avoid Cyber Crime is not to click on the link of any tempting message, if you do, then also check the URL of that link to see if there is any spelling mistake in it. Also, create a strong password for any of your accounts, which include uppercase and lowercase characters and be safe.
