Common network security vulnerability prevention technology

Common network security vulnerability prevention technologies include firewall, antivirus software, encryption technology, access control technology, security scanning and vulnerability assessment tools.

1, firewall

Firewall is a kind of network security equipment, which is usually installed at the boundary of enterprise network. It can monitor network traffic and block unsafe network connections according to rules. Firewall can filter out some malicious attacks and viruses to ensure the security of the network.

2. Antivirus software

Antivirus software is a kind of software specially used to detect and remove computer viruses. It can quickly and timely detect viruses, trojans and other malicious software that have entered the computer system, and isolate or delete them. By using anti-virus software, the stability and security of the computer system can be guaranteed.

3. Encryption technology

Encryption technology is a technology that encrypts sensitive information through algorithms to protect information security. When we do online shopping or online banking, encryption can encrypt our website access and transaction data to prevent data from being intercepted and stealing information. Encryption technology can effectively protect the security of personal information.

4. Access control technology

Access control technology is an effective network security measure. It can restrict the access rights of network users by means of authority control and identity authentication. This can ensure that only legitimate users can access the network, thus ensuring that the sensitive data of enterprises or organizations will not be leaked.

5. Security scanning and vulnerability assessment tools

Security scanning and vulnerability assessment tools help identify potential security risks in the network. These tools can scan network devices, find possible security vulnerabilities and provide corresponding repair suggestions.
