    Looking for tips on how to secure your Linux cloud? Linux offers many options for hardening your system and preventing unauthorized access. Some best practices for making sure your Linux cloud remains secure include encrypting communications, monitoring login authentication, using SSH-keys instead of passwords, setting up a firewall, updating your system, frequently scanning for malware and implementing an intrusion detection system.

    One of the first things you should do after deploying a new cloud server is to make sure it will stay secure. Linux offers a multitude of options to help prevent unauthorized access and harden your system. In this how-to guide, you can find some commonly recommended steps in order to protect your cloud server.

    When connecting to your cloud server all traffic will pass through the public network, that anyone could be eavesdropping on, unless you take measures to secure your communication. Avoid using any unencrypted transfer protocols such as Telnet and FTP, or anything that would send passwords or other sensitive information as plain text. Instead, you should use SSH (Secure Shell), SCP (Secure Copy), SFTP (SSH File Transfer Protocol) or rsync for all your remote control and file transfer needs.
