How Can You Ensure Security on a Server?

It is important to secure your server to prevent data loss or security compromises. Because security is such a challenging subject for many, it often goes unheeded. Many are caught unaware when an issue arises. By following these best practices, you can significantly lower your risk of being compromised by a malicious actor.

Zero Trust security is the concept, methodology, and threat model that assumes no user, system, or service operating within a secured internal environment should be automatically trusted. It put forward that every interaction must be verified when trying to connect to a system before being granted access. This concept uses micro-segmentation, and granular edge controls based on user rights, application access levels, service usage, and relation to the location to determine whether to trust a user, machine, or application seeking to access a specific part of an organization.

What is OpenSSH?

OpenSSH is an open-source utility developed by The OpenBSD Project. SSH stands for "Secure SHell." This service encrypts traffic on both ends, eliminating security risks from hackers or eavesdroppers. It can be used for remote operations like file transfers and offers key-based passwordless authentication. In this tutorial, we will demonstrate how to harness the power of SSH's on your Windows server to send basic remote commands and transfer files using password authentication.

Our last article on Ubuntu security suggestions touched on the importance of passwords, user roles, console security, and firewalls. We continue with our last article and while the recommendations below are not unique to Ubuntu specifically (nearly all discussed are considered best practice for any Linux VPS server or dedicated server) but they should be an important consideration in securing your server.
