Types of cyber attacks (diversification of cyber security threats)

A network attack refers to the act of using a computer network to attack other computers or networks. Network attacks have the characteristics of concealment, high efficiency, extensiveness and instantaneity, which pose a serious threat to network security. There are many types of network attacks. Below we will introduce several common network attack methods in detail.

1. Phishing attack

Phishing attack refers to the use of fake websites, emails, text messages and other means to deceive users into providing personal information or sensitive information, thereby achieving the purpose of illegally obtaining information. There are various methods of phishing attacks, but the basic steps are similar, as follows:

1. The attacker creates fake websites, emails, text messages, etc., pretending to be a legitimate organization or individual.

2. Attackers send fake websites, emails, text messages, etc. to users to induce users to click on links or enter personal information.

3. Users enter personal information on fake websites, emails, text messages, etc., and attackers obtain users’ sensitive information.

2. Denial of service attack

A denial of service attack means that the attacker uses some method to prevent the target system from providing services normally, causing system paralysis or service unavailability. There are many types of denial-of-service attacks, but the basic steps are similar, as follows:

1. The attacker uses a large number of requests or attack code to send a large number of requests to the target system.

2. The target system cannot process requests normally due to too many requests or too many attack codes, resulting in service paralysis or unavailability.

3. Malware attack

Malware attack means that the attacker implants malware into the target system in some way to illegally obtain information or control the system. Purpose. There are many ways to attack malware, but the basic steps are similar, as follows:

1. The attacker creates malware and implants it into the target system.

2. The malware begins to execute the attacker's instructions to achieve the purpose of illegally obtaining information or controlling the system.

4. Password cracking attack

Password cracking attack means that the attacker cracks the password of the target system in some way, so as to illegally obtain information or control the system. There are various methods of password cracking attacks, but the basic steps are similar, as follows:

1. The attacker obtains the account number and password of the target system.

2. The attacker uses password cracking tools or brute force to crack the password of the target system.

3. Attackers use cracked passwords to illegally obtain information or control the system.

End

There are many types of network attacks, and the attack methods are ever-changing, posing serious threats to network security. In order to protect our own network security, we need to strengthen our network security awareness and improve our network security protection capabilities. At the same time, enterprises and institutions also need to strengthen network security construction and establish a complete network security system to ensure network security.
