Introduction

As firms advance towards a more modern infrastructure, the Desktop-as-a-Service (DaaS) model is becoming an increasingly popular cloud-based system. Desktop-as-a-Service is a multi-tenant, cloud computing solution in which a service provider furnishes a virtual desktop to an end-user over the internet. A provider typically manages the infrastructure, including the security updates, available desktop applications, data storage, and backups. In specific instances, DaaS users manage these services individually. According to Gartner via Workspot:

Cloud computing is a model for empowering users to access a useful, network-accessible, shared pool of resources that allows for quick changes to settings and configurations with minimal intervention from a service provider in an easy-to-maneuver self-service management interface.

Introduction

Just as regular visitors reach our server every day, so do others with more nefarious intentions. It is simply not reasonable to run an online service without some layer of protection. To protect against some of these attacks, Ubuntu ships with ufw (Uncomplicated Firewall). This is a tool designed to make Ubuntu firewall management as easy and user-friendly as possible. Specifically, ufw provides a cleaner interface for the core firewall tools netfilter and iptables, which, while robust, can be challenging to master.

CentOS Options

With the recent announcement by CentOS 8 regarding the switch from CentOS 8 to CentOS Stream, this commonly used Linux distribution is being relegated to a mid-stage development version of RHEL. In essence, CentOS 8 becomes an early rolling-release distro for RHEL. As CentOS moves from being a follow-up distribution to the stable version of RedHat, to be, in effect, a prerelease version of RHEL, many users are looking for alternatives to replace their current operating systems with a long-term stable platform apart from RHEL and IBM who owns RedHat.
