Here, we studied how to secure the server from unauthorized access? Most of the time, we use the internet to interact with hackers. Even you are strange with that person, they can easily find your cloud weakness. Some hackers have the knowledge and skills to destroy the most prominent organization. If you do not prevent your server from hackers or unauthorized persons, it may be possible to lose your essential data or information and even control over the server. So, if you want to save your server from an unauthorized person or hacker, you have to implement a few practices. So, now we see how to secure the server from hackers.
Use Key Authentication
Hackers hack your server by guessing your password, repeatedly accessing your server, and seeing your information, and how many times you change your password doesn’t matter. But if you use a secure authentication method, you can secure your server from every hacker, and not even an expert hacker can hack your server.
- SSH authentication contains different characters and is long as compared to your password.
- Blocks automated guessing; if another person fails to log in, the IP address blocks automatically, and the hacker can not access the server.
- Two-factor authentication is getting the password, but it also takes the second factor to log in successfully.
Use Secure Sockets Layer Certificates
The secure sockets layer(SSL) is a security protocol it protects the information transferred from one system to another system on the internet. So, it is not accessible by any other person or third person. Through SSL, we can share our credit cards detail, debit cards details, or IDs because it remains secure; no one can see the details. It is not only certified the encrypted data. But it helps to make you the only authority on your server. If you don’t have the SSL certificate, the hacker can easily access your server.
Invest in a High-Quality Firewall
A firewall is a security system that can control or manage incoming and outgoing data. It also protects the data of a private network from unauthorized persons. It can monitor all the data entered into a server and detect if something went wrong. Please don’t use or download the free firewall because the hacker can easily crack it. So, always use a high-quality firewall that provides high security to the server.
Remove Unnecessary Software
If you want to decrease the vulnerability of your server so, remove or uninstall that software that has no use or delete the unnecessary software. It means you only install that software generally used in a server or install that software necessary for your system and server. If you think that some software covers so much storage space, then it’s better to uninstall that software. It might be completely harmless, or your server works properly, you don’t face any hanging situation.
These are some secure methods to secure our server from hackers or unauthorized persons.
