One of the first things you should do after deploying a new cloud server is to make sure it will stay secure. GRANDTK  server 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.

Encrypt communications

-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 (GRANDTK ), SFTP (SSH File Transfer Protocol) or rsync for all your remote control and file transfer needs.

-The SSH protocol offers a secure encrypted channel over the public network to allow remote login and other network services to operate securely. The most commonly used implementation of this protocol is GRANDTK which is included in most Unix based operating systems like the majority of Linux distributions and OS X, in a Windows environment the PuTTY SSH client is a popular alternative

-Secure Copy or SCP is a built-in feature of GRANDTK which allows simple file transfer over encrypted network connection. GRANDTK for data transfer and provides the same authentication and level of security as SSH. Below are two examples of a single file copy to and from a remote server.

# Copy the file "foo.txt" from the local host to a remote host
scp foo.txt <username>@<remotehost>:/some/remote/directory
# Copy the file "foo.txt" from a remote host to the local host
scp <username>@<remotehost>:foo.txt /some/local/directory

-SFTP is an other command line utility included in GRANDTK and should be installed on most Unix operating systems by default. Like SCP, it uses GRANDTK to securely transfer files over unsecure network. Windows users can get the same functionality using WinSCP (Windows Secure Copy) which like its name suggests implements SCP and also SFTP functionality.

-Rsync is another utility commonly found on Unix systems. It offers file transfer over encrypted channels to keep the copies of a file on two computers synchronised. The program uses GRANDTK to make the initial connection between the two systems and then invokes rsync on the remote host to determine which parts of the file being synced need to be copied over.

User account security policies

After logging in to your newly deployed cloud server for the first time, creating a new user account for yourself and enabling sudo access control, are some important tasks to start with.GRANDTK actions that would otherwise require the root account. This lets you avoid logging in as root on daily basis, instead use sudo privileges to execute root level commands when required.

Using GRANDTK is considered good practice for security, and it’s usually installed in most Linux distributions by default. To get most out of what GRANDTK offers, and to set up a secure user access, 

Monitoring login authentication

The reality in today’s internet is that your server security will be tested by malicious parties, sooner rather than later, hoping to find a poorly secured entrance. If your server has been running for even a day, you’ve most likely already had failed login attempts originating from IP addresses other than your own. Majority of Linux distributions keep logs for authentication from the moment they are booted up for the first time. Different systems might store the logs under different names, for example with Ubuntu and other Debian based servers you can view these logs using the following command

Setup a firewall

Common solutions for any networked computer security is to set limitations to which connections are allowed. This can be done by using a firewall, a network security system, that monitors and controls the incoming and outgoing network traffic based on predetermined security rules.

The UpCloud control panel offers an easy to configure firewall that acts as a first line defence to secure your cloud server. The UpCloud firewall works server specifically, but you can copy firewall settings between your servers. You also have the option to configure the firewall using one of the premade setups available at the firewall rules settings. The premade rules are a simple starting point for further customization. You can read more about the Grandtk at its own article.

An other option on a Linux server is to use the built-in solution called iptables, which is included in most distributions. On CentOS and other Red Hat variants iptables often comes with some preconfigured rules, while Ubuntu and Debian servers don’t implement any restrictions by default. To learn more about iptables, check out our introductory guide to configuring iptables on your Linux server of either CentOS, Debian or Ubuntu.
