Also known as Secure Shell, SSH is a widely recognized network protocol that keeps communication through computer safe and secure. It is used as a means of connecting to the World Wide Web without having to worry about unwarranted third-party interruptions.
SSH is also compatible with a lot of major operating systems (OS), including Windows and Linux. It is what people employ if they have sets of data that they want to be accessed only by authorized users.
Any trusted website should be safe from hackers, online frauds, and malware. As such, SSH is important, especially if your site contains important data, files, or other sensitive information. Online businesses and other sites that involve online transactions are most especially in need of SSH.
Keep in mind that any loophole in your site’s security is festive to the eyes of online thieves, so you need to be prepared at all times.
The Importance of SSH
If you’re working on a regular website (one that does not contain any private information), then SSH may not be your top priority. Here are the following reasons you should value SSH:
- When you have important data that should only be accessed by your team or an authorized personnel.
- When you have data that you think online frauds and hackers would be interested in getting.
- When you have files that has to be limited to your own website.
Ways of Getting Your SSH Server Secured
Having an SSH for your website ensures safety for all your important files and data. However, it would be better to get your SSH to its maximum potential in protecting your site. Your open SSG server could work better by incorporating these things on it. This, however, may require advanced technical knowledge which will be your key to achieving a high level of security for your site.
If, however, you are not able to set up the SSH server, you can hire a professional or have a tech friend do the following:
- Remove your open SSH server. Tap on yum command in order to disable your server. Your computer and other connecting gadgets will still be able to function and you will not be required of file transfers or even remote logins for this.
- Do away with SSH-1. This is the version 1 of SSH and has now been marked as obsolete due to various security issues. Do not use this version. Double-check your system to make sure that you are not employing this. Check on your sshd_config file. You should be able to see “Protocol 2” on the display.
- Set your firewall at SSH port 22. Navigate the pf (packet filter) firewall configuration or the iptables, and set a firewall right on the ssh port 22.
- Set your restrictions to the SSH access. Change your system from its default status and allow only authorized users on your SSH.
- Block the root login. Using the sshd_config, set in “PermitRootLogin no” to block the root login.
- Never leave your SSH sessions unmanned. Doing so will eliminate possible attacks towards your site. You can make this happen by configuring your timeout interval. This is done by opening the sshd_config and setting the interval for your computer. If on that set interval, one user becomes inactive, that will automatically be eliminated from the system.
- Use secure passwords for your SSH. You can check on OpenWall’s John the Ripper password cracker for password formulas that are difficult to hack or manipulate. You can employ such passwords into your system to better secure it.
