Nginx is a high-performance web server and reverse proxy server that is the choice of many Internet companies. However, no matter how powerful the software is, it cannot be completely free of vulnerabilities, so how to deal with security issues including vulnerabilities in Nginx has become an important topic.

The following are several steps recommended for you to deal with Nginx security issues:

Understand Nginx security vulnerabilities

First of all, you need to understand the security vulnerabilities of Nginx, which will help you Be aware of possible problems as soon as possible. You can refer to the [Official Security Vulnerability Page](http://nginx.org/en/security_advisories.html), or use the tool [CVE Details](https://www.cvedetails.com/vulnerability-list/vendor_id-7310 /product_id-14714/year-2020/Nginx-Nginx.html) to retrieve and compare. In addition, following Nginx forums and communities, as well as Nginx-related blogs and news, can help you stay up to date with the latest vulnerability information.

Update Nginx regularly

Secondly, you need to update Nginx regularly. Every time a new version is released, developers fix known vulnerabilities and errors and improve the performance and security of the software. Moreover, new versions may also bring new features and functionality. Therefore, keeping the latest version of Nginx is very important to reduce security risks and improve user experience.

Enable HTTPS

Third, you need to enable HTTPS. In today's Internet environment, using HTTP to transmit sensitive data is very dangerous because the protocol does not encrypt the data. HTTPS, on the other hand, encrypts and authenticates data transmission via SSL, providing higher data security. If your Nginx is running an HTTP website, it is recommended that you upgrade to HTTPS.

Configure firewall and reverse proxy

In addition, you can protect your Nginx server by configuring firewall and reverse proxy. Firewalls can filter unnecessary traffic and access, thereby ensuring that your server is protected from attacks to a certain extent. If your server is subject to a DDoS attack, a reverse proxy can reduce the load on the server and reduce the impact of the attack by hiding the real IP address, caching content, and providing load balancing.

Ensure the validity of Nginx logs and monitoring

Finally, you need to ensure that Nginx logs and monitoring are valid. Logs can help you view access records and anomalies to identify possible security issues. If necessary, you can analyze logs to understand the attacker's attack methods and strategies. Monitoring gives you real-time visibility into server status and performance, helping you respond promptly to failures and attacks.

To sum up, by understanding security vulnerabilities and regularly updating Nginx, configuring HTTPS, firewalls and reverse proxies, and ensuring the effectiveness of logs and monitoring, you can better protect your Nginx server and prevent attacks and Data breach.
