What are the threats to network security?

Network security faces many threats. Here are some for you:

1, virus

Virus is a kind of malicious software, which spreads and destroys files, programs and systems by lurking in computer systems. They are usually spread by infecting executable files or file systems. Once the infection is successful, the virus will replicate itself and spread to other files or computers.

2.spyware

Spyware is a kind of malicious software designed to quietly monitor and collect information on users' computers. They can track users' online activities, keyboard records, browsing history and so on, and send this information to attackers.

3. Spam

Spam is a large number of unsolicited e-mails sent to a large number of users. Spam not only occupies users' storage space and network bandwidth, but also may contain fraud, malware or fraudulent links, which poses a threat to users' privacy and security.

4. fishing; catch fish

Phishing is a social engineering attack. The attacker pretends to be a trusted entity and gains sensitive information, such as user name, password and credit card information, by deceiving users. Phishing attacks are usually carried out by email, SMS, social media or malicious websites.

5. Unauthorized access

Unauthorized access means that an attacker illegally gains access to a computer system, network or data. This can be achieved by guessing passwords, exploiting weaknesses or vulnerabilities, and bypassing authentication.

6. Denial of service attack

Denial of service attacks are designed to prevent the target system from providing normal services by sending a large number of requests or occupying a large number of system resources. As a result, the service is unavailable, which affects the user experience and normal business operation.

7. Social engineering attacks

Social engineering attack is a technology to obtain confidential information or illegally access the system by deceiving and manipulating people's social tools and psychology. Attackers may disguise their identities, use people's kindness or use other deceptive means to induce victims to disclose sensitive information.

8. Password cracking

Password cracking means that attackers use various means and tools to decrypt or crack passwords in order to gain unauthorized access to systems or accounts. This may involve brute force cracking, dictionary attacks or attacks against weak passwords.

9. phishing

Phishing is a highly customized phishing attack aimed at a specific individual, organization or industry. The attacker deceives the victim by collecting personal information and background knowledge of the target and making realistic camouflage information.

10, sniffing attack

Sniffing attacks intercept and steal sensitive information by monitoring network traffic. Attackers can use special software or equipment to capture and analyze network packets and get valuable information from them.
