Types of Cyber Crime

Types of cyber crime

Cyber crime is done in different ways, some of which are given below-

1. Hacking: In this type of cyber crime, hackers enter a restricted area and gain access to another person's personal data and sensitive information without that person's permission, the restricted area is someone's personal computer (PC) / Laptop, mobile Or someone online. Can have a bank account (net banking).

2. Cyber Theft: In this type of cyber crime hackers violate copyright law and it is a part of cyber crime which means theft done through computer or internet. This includes information theft, password theft, identity theft, internet time theft, etc.

3. Cyber Stalking: This cyber crime is being seen more in social media sites. In this, the stalker harass the person by repeatedly sending dirty messages or emails. In this, often stalkers make victims of small children and such people who do not have much knowledge of the Internet. After this, the pursuers start blackmailing that person, due to which the life of that person becomes very painful.

Hackers get into a lucrative conversation with a person to get that person's bank account, debit card details, internet banking details then hackers take out all the money of a person.

5. Malicious Software: Many such dangerous software is created by hackers who can not only steal the data of computer or mobile by connecting to any internet but also delete it, also hackers can hack your entire system with the help of these software can crash your entire system.

These software are of many types such as malware, spyware, virus, ransomware and worms. Hackers send this type of software, mostly through links, pop-up messages or emails, to other computers and attractively ask them to touch the links. If that person touches the link, the hacker takes full control of the computer.

6. Phishing: In this type of cyber threat, the hacker sends a message or email to a person posing as a trusted institution or bank, which looks absolutely legitimate. The hacker's motive behind this is to cause financial harm to that person by taking sensitive information like bank account number, debit card etc.

7. Child Pornography and Abuse: In this type of cyber crime, hackers mostly use chat rooms and talk politely by hiding their identity. Young children or minors do not have much knowledge and gradually hackers obstruct children for child pornography. When children become victims of pornography, they are blackmailed and are unable to even tell their parents due to fear.

8. Man in the Middle (MITM) Attack: In this type of cyber crime, 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 the real friend Sounds like talking. Information, and sensitive data such as bank, debit, credit card details etc. Due to this, the person in front does not even know and all the information comes to the hacker.

Along with this there are many services like yahoo, hotmail or any Email etc. When suddenly there will be a lot of traffic, if a user goes to log in, the user will not be able to use that service.

10. Spoofing: In this type of cyber attack, the hacker can use the identity of another person to attack a large server or system of a large company. A hacker can destroy someone's life by taking the help of this attack.

11. Salami Slicing Attack: "Salami Slicing Attack" is also also known as Salami Fraud. In such cyber crime, cyber criminals make a big attack by doing many small attacks. Attackers use customer information such as bank/debit card details to deduct small amounts of money.

Due to less money being deducted, customers remain unaware of slicing and do not even complain about it, due to which the hacker is not detected. It is just a strategy to make profit from small increments from time to time.

It is true that thieves have a lot of brains so often new types of cyber crimes keep coming up. Apart from these, many more cyber attacks are taking place, with the passage of time new types of them are also being discovered.

Types of Cyber Security

In cyber security, different security is given to the user in different layers of the network. All the crimes mentioned above are done online and six best cyber security to prevent them are as follows-

1. Network and Gateway Security – This can be called the first layer of the network. You must have heard the name of Firewall in the computer. It's a wall for a network that only allows secure things in and keeps unsafe threats out.

2. Data Loss Prevention (DLP) - In this process all the data of the user is fully encoded using SSL (Secure Socket Layer). Data is encrypted under this protection, to keep it away from unauthorised access. This process increases the security of the data, with no risk of data theft or leaking, i.e. the data is completely encoded.

3. Application Security - By this the applications being used in the network go through a security process. This is done to overcome the shortcomings of the application. Also, if that application is vulnerable then it is taken out of network.

4. Email Security – If you use Gmail, you may have noticed that some emails go to the Spam folder. Email is provided security by installing spam filters in the network. So that harmful emails can be kept out of the reach of the user because most of the crimes are done through email phishing.

5. Antivirus Security - Every person who accesses the Internet or uses external memory on his PC or Laptop installs Antivirus in his PC or Laptop. This antivirus protects our PC or laptop from different types of viruses. Nowadays we all keep our important data, sensitive information and personal files saved in the computer itself. Therefore, keeping it safe is a very important task.

6. Network Access Control - By this the work is done to keep unauthorised users and devices out of the network. NAC protects the functionality of the network, ensuring that only authorised users and devices have access to it. Network operators determine which devices or applications comply with endpoint security requirements through their own specific programming and whether or not they will be allowed network access.

Connecting to the network is a very secure process, in which policies are made according to the users and their network related rights are limited.

Along with all these security layers, an internet user also needs to follow certain rules at their level, such as using strong passwords and not opening unknown email attachments.
