Critical Error Solutions in Cyber Security: Server Optimization

Server Optimization in Cyber Security

Cyber security has become more critical than ever in today's digital world. The security of servers plays a vital role in protecting against cyber attacks. In this article, we will examine the logic of server optimization and explain how to solve critical errors step by step.

1. Importance of Optimization

Server optimization is essential not only for improving server performance but also for closing security gaps. Low-performing servers are more vulnerable to cyber attacks. Therefore, optimizing your server settings is one of the key steps to creating a high-performance and secure infrastructure.

2. Step-by-Step Server Optimization

Now, let's explore the necessary steps for server optimization:

• 2.1. LiteSpeed Settings: The LiteSpeed web server is optimized for high performance. It is important to make the following settings:

Open the httpd.conf file:

sudo nano /usr/local/lsws/conf/httpd.conf

Add or update the following settings:

MaxConn 1000
MaxKeepAliveRequests 100
KeepAliveTimeout 5

• 2.2. MySQL Optimization: To enhance MySQL database performance, edit the my.cnf file:

Open the my.cnf file:

sudo nano /etc/my.cnf

Add or update the following parameters:

innodb_buffer_pool_size = 1G
query_cache_size = 128M
max_connections = 200

• 2.3. DDoS Protection: Configure iptables or firewall settings to protect against DDoS attacks:

To edit firewall settings:

sudo iptables -A INPUT -p tcp --dport 80 -m conntrack --ctstate NEW -m limit --limit 10/min -j ACCEPT

3. Check for Updates: Ensure that your server software is up to date. To check for updates:

sudo apt update && sudo apt upgrade

4. Implement SSL Certificate: An SSL certificate enhances data security. To obtain a certificate using Let's Encrypt:

sudo apt install certbot python3-certbot-nginx
sudo certbot --nginx

Conclusion

By following the steps above, you can enhance your server's cyber security and optimize its performance. Remember, security is an ongoing process; therefore, you should regularly review your settings.
