Nowadays, the subject of vps hosting security is by all accounts all over the place, a concern talked about among huge organizations as well as people with an online presence.
In this article, we’ll explicitly address security measures for Virtual Private Server (VPS) Hosting, where we’ve identified approaches to keep your VPS secure.
Why You Should Secure Your VPS?There are several vulnerabilities in web hosting today. Even the data stored on the dedicated servers with multiple protections can get hacked, and users’ data will be lost on the public platform.
Stolen financial and personal information is sold on the dark web, and some files are leaked on the public platforms by hackers. Study shows that cyber-attacks have picked the speed in recent years.
Many DDoS attacks on popular platforms have been recorded by the top companies in the world. These kinds of attacks can demolish the website content and leak the data to the public platform.
We will discuss how VPS security works and protect personal information from hacking. The guide will answer one of the most common questions ask on the web “how to secure VPS?”
In the case you aim to know the difference between public and private cloud , this post can guide you!
How To Secure VPS?
1) Installing Fail2ban
Fail2ban is the log parsing algorithm that keep eye on every activity happening on the server in the form of system logs. The application tracks the automated attacks on your server from an unknown source and alerts the users.Too many password failures, exploitation of the files, injecting data into the file are recorded in the malicious signs. You will find the scan log files stored on the server, for example, “/var/log/apache/error_log” and ban the IP address.
2) Using complex and unpredictable passwords
Once you get control of your VPS hosting server from your service provider, the first thing that you should do is to change the password. Use a strong password that is unpredictable and more personalizes only you can remember. It will ensure VPS security and avoid data breaches.
The Brute force attacks are normally focused on the ordinary password generated by the servers. Brute force attacks are done to infiltrate your system. Complex passwords are difficult to crack. It is nearly impossible to reach your files on the server when the password is secure.
- Tips to choose the strong password
- Use a minimum 12 character password
- Mix the password with upper and lower case letters
- Use the combination of numbers and letters
- Put some non-numeric and non-letter characters in the password
3) Disable Protocol 1
The SSH service is design to work on two types of primary protocols named protocol 1 and protocol 2. Protocol 1 is less secure compare to protocol 2. So it is advisable to use protocol 2 while you are using the VPS hosting for communications.
- Before you start using protocol 2, ensure to disable protocol 1. Else it will be accessible to the users. Hacker will use it as the backdoor to enter the server.
- Open the sshd_config file using the editor.
- nano /etc/ssh/sshd_config
- Find the below statement and change it to “protocol 2”
- # Protocol 2,1
- Protocol 2
- Once the changes are successfully applied, restart the SSH server and save the file.
- Use the command
- Service ssh restart
4) Disable IPv6
IPv6 comes with many advantages. It has become the first choice of the hacker when they want to attack mass websites with the automated script. IPv6 is not used often hence you have special requirements for your website.
Consult with your developer and see if they need the IPv6 support on the VPS hosting server. If it is not in use, disable it immediately. IPv6 receives malicious traffic. Blocking them would put your data secure.
- To disable IPv6 on your server, go to the below file path.
- /etc/sysconfig/ network
- And update the settings.
- You will read the file as NETWORKING_ IPV6 = no and IPV6INIT = no.
5) Use GnuPG Encryption
In most cases, the data is hacked during the transition from one place to another. Hence, encryption is essential to protect the data from getting a leak and is accessible to the hacker. GnuPG is used to encrypt the data over the network and authenticate the system.
The system consists of the public key that only gets described using the private key available with the recipient. Without the private key, the system that trying to decrypt will not able to crack it.

6) Use Sftp Instead of FTP
FTP is the oldest file management tool no longer consider as the secure port to access the file on the server. Even the server is considering the “FTP over TLS” connection is not secure.
Both the connection FTPS and FTP is vulnerable to hacking. On the other hand, SFTP also known as the FTP over SSH would encrypt the data and secure the server.
7) Activate cPHulk in WHM
With the firewall security, you also get an additional “cPHulk” brute force security system on your VPS server. The firewall also comes with the limitation. Sometimes the firewall makes mistakes in identifying the anonymous entry which generally occurs due to incorrect firewall settings in the system.
Availability of the cPHulk security system gives double protection to your server with the firewall. Prevent any brute force attack and protect the server from data leakage. When unusual activities are detected on the server, cPHulk blocks the login features of the server. The firewall later blocks the entire IP.
You can activate the cPHulk on your VPS server by going to the WHM Security center. Choose the cPHulk brute force protection and activate the feature on your server. cPHulk will enhance the security of your server.
8) Install a Rootkit Scanner
A rootkit is a devil of the server that gets installed on your system at the operating level. It becomes hidden to all the security software that scans only the upper level of the files and ignores the operating system files. A rootkit is mostly undetected on the server until you manually check or use a special rootkit scanner to identify the file.
Use the Chrootkit which is an open-source tool developed to find the infected files on the server. Remember that, the Chrootkit may not offer you 100% guarantees to detect the rootkit virus on your operating system. The only way to remove the rootkit is to reinstall the operating system.
9) Audit The Server
10) Modify The Default SSH Login
11) Disable Unused Services And Close Unnecessary Ports
12) Utilize The Latest Software Versions
13) Eliminate Unwanted Packages/Modules
14) Set Up Your Firewall
15) Implement Antivirus Programming
16) Perform Frequent Backups
17) Use SSL Certificates for Everything
