DDoS attacks It is one of the most common network attacks on the Internet today. It mainly uses up the resources of the target server through a large number of malicious traffic, so that it cannot run normally. Hong Kong server When dealing with DDoS attacks, we usually take a series of protective measures to guard against various network security threats. Let's introduce the server security protection measures in Hong Kong for reference!
In order to protect the security of Hong Kong servers, we can deploy security measures from network security, system and application security, data security, application layer security, etc., as follows:
1、 Network security
To protect the network security of Hong Kong servers, we can start with firewall configuration, defense system, etc. Firewall configuration mainly includes two aspects: hardware firewall and software firewall. When deploying the hardware firewall, we can filter malicious traffic through settings. When configuring the server's software firewall, we can restrict unnecessary port and service access. The defense system is to install intrusion and defense systems on the server, deploy IDS/IPS, monitor and prevent suspicious network activities. These measures can improve the security protection capability of Hong Kong servers.
2、 System and application security
System and application security is mainly reflected in regular updates of operating system patches and security updates, timely updates of all applications and services, and repair of known vulnerabilities; Secondly, user rights management is carried out. The principle of minimum rights is adopted. Only necessary rights are allocated to users and services to avoid unnecessary accounts with high rights. At the same time, strong password policy is used to change passwords regularly to avoid using default passwords; Finally, there is access control, enabling two factor authentication to enhance login security, and using SSL keys instead of passwords for server access;
3、 Data security
Hong Kong server The data security protection measures of are mainly embodied in two aspects: data encryption and backup recovery. Data encryption includes transmission encryption and storage encryption. By using SSL/TLS to encrypt all data transmission, ensure that data is not eavesdropped and maliciously modified during transmission, and encrypt and store sensitive data to prevent data leakage. It is not difficult to understand backup and recovery. Regularly back up data and system configuration to ensure that data can be recovered quickly in case of data loss or damage. Also, it should be noted that encryption can improve the security of backup data when backing up data.
4、 Application layer security
To protect the security of Hong Kong server application layer, we need to deploy WAF, use web application firewall to protect websites and web applications, and prevent common web attacks, such as SQL injection and XSS attacks. In addition, when developing applications, we should try to follow the security coding time to avoid common vulnerabilities. At the same time, we should also conduct code audit and security test regularly to find and repair potential security vulnerabilities.
When dealing with DDoS attacks, we can deploy Hong Kong server security protection measures from four aspects: network security, system and application security, data security and application layer security. Through the above measures, we can greatly improve the security of Hong Kong servers and protect them from various network attacks and security threats.
