How to Increase the Security of Your Server

February 27, 2023 / Web Security


In today’s world, one of the most significant articles for internet users who work 24×7 on the internet. Our website’s security is a major concern for everyone. As a result, here is an article that will help you secure your server.

Hackers are always looking for server weaknesses in websites, as we all know. It is your responsibility to ensure that your data is secure. All web hosting companies and server administrators should be aware that server security is an important part of server management.
We’ll look at strategies for hardening servers and monitoring them for security issues in this blog post.

We’ve given some consideration points to server security risks.

1. Use public-key authentication for SSH.

Access that isn’t encrypted must be removed. Telnet, FTP, and HTTP should no longer be used to manage servers. SSH, SFTP, and HTTPS are the permitted protocols. For even more security, disable password authentication from SSH entirely. Instead, use SSH keys. As a result, each user has both a public and private key. The user contributes to the security of the private key. The public key is kept on the system. When a user tries to log in, SSH verifies that the public and private keys are now identical. Once password logins are disabled, there is no possibility of a successful brute-force assault against a weak password.

2. Make your Password Strong.

Criminals face a challenge when dealing with a hardened server since many server administrators leave the front door wide open. People, even those who should know better, develop the habit of using passwords that are easy to guess. Last year, a surge of ransomware assaults resulted from brute force attacks on servers using weak SSH passwords. Finally, restrict login type access to users by using long and random passwords—longer passwords are better

3. Make sure to install and setup CSF Firewall

Config Server Firewall is a free firewall with a lot of features that may protect a server from a variety of attacks. One of its characteristics is packet filtering inspection, authentication failure rate-limiting, flood protection, directory monitoring, and the use of external blocklists. CSF is a fantastic tool that is a lot more convenient than utilizing tables.
