The Basics of VPS Security

In order to guarantee a safe and secure VPS environment, it is it is imperative that you follow these simple steps once you receive the access credentials to your Jolt VPS.

While it’s true that one of the benefits of virtualisation is that the physical host would not be affected should a virtual private server’s security were weakened, you wouldn’t want to risk exposing your VPS to harm to begin with. The key is to prioritise security for whatever reasons you are operating a VPS.

Tips for Securing Your VPS

  • Install any and all available software updates – New weaknesses are determined and exploited every day which is why it’s of the utmost importance to find out if there are any available security updates for the Linux distro installed on your virtual private server, not just in the beginning but also periodically.
  • Choose strong, secure passwords

    Some of the most common security threats include brute force and dictionary attacks. For this reason, the importance of choosing strong and complicated passwords when you create or maintain VPS user accounts cannot be overstated. Refrain from using passwords that are easy to guess, such as street names, names of family members, pet names and ordinary words found in the dictionary. Experts define strong passwords as having a complex blend of capital and lower case letters, numbers, special characters, with a minimum of 8 characters. It is also recommended that you change your passwords frequently, and that you require your users to do the same.

  • Use a secure file transfer method – While FTP is one of the most popular file transfer methods, it really isn’t the safest. We recommend using encrypted SSH if you want to protect your sensitive data; SFTP is one such method.
  • Backup all your files

    Schedule routine, off-site, automated backups so that you can easily recover should anything untoward occurs.

  • Delete unused user accounts – Keeping user accounts that have expired, are not in use and left from previous users expose you to potential security risk. It’s best to delete any and all unused user accounts and retain only those that are currently active and in use.
  • Utilise a firewall – Services, ports and applications should be protected as strictly as possible. Keep a close eye on your system and web server logs, frequently checking for signs of attempted intrusion, and if you detect any, make sure to block those IP addresses or IP ranges. Only allow inbound traffic from trusted IP addresses on sensitive ports.

The administrative work that a VPS entails, while not exactly the same as a dedicated server, is quite similar. In order to enjoy the benefits of your VPS, you need to give it your full attention and ensure its security.
