One of the most important articles for internet users who work on the internet 24 hours a day, seven days a week. Everyone is concerned about how to secure our website. So, here is an article that will assist you in securing your server.
Hackers are lookout for server weaknesses. It is your responsibility to ensure the security of your data. For web hosting providers and server administrators, server security is a significant aspect of server management. In this blog post, we’ll look at techniques for hardening servers and monitoring them for security flaws.
Some suggestions for making your server more secure
- For SSH, use public-key authentication
Unencrypted access must be erased. No one should manage servers utilizing telnet, FTP, or HTTP anymore. The accepted guidelines are SSH, SFTP, and HTTPS. Disable password authentication from SSH altogether for even increased protection. Use SSH keys instead. So each user has a public and a private key. The user helps to keep the private key. The system hosts the public key. When a person tries to log in, SSH confirms that now the public key matches the private key. There is no risk of a successful brute-force attack against a weak password once password logins are disabled.
- Passwords that are hard to know
A hardened server poses a challenge to criminals because you’d be surprised how many server administrators leave the front door wide open. People, including those who should know better, get a habit of choosing passwords that are easily guessed. Brute force attacks on servers with weak SSH passwords resulted in a wave of ransomware attacks last year. Use long and random passwords—longer passwords are preferable, and finally, restrict login type access to users.
- Install and Setup the CSF Firewall
The Config Server Firewall is a feature-rich, free firewall that can protect a server from a range of threats. Packet filtering inspection, authentication failure rate-limiting, flood protection, directory watching, and the use of external blocklists are one of its features. CSF is an invaluable method that is far easier than using tables.
- Maintain Software Updates
Keep Software Upgrades If you ignore the remainder of this article’s advice, which you should not, you should at the very least update using your Linux distribution package manager.
- Backup Regularly
Backups don’t seem like a security measure, but the main reason we secure a server is to secure sensitive information stored on it. Since it is impossible to guarantee that a server will never be tried to hack, data should be encrypted and backed up to an offsite location. Regular testing of recovery from comprehensive backups will make ransomware attacks inefficient.
We provide several documentation articles on general system security that discuss standard practices you can use to improve server security.
