Software is no longer run locally, as some of it is now run or downloaded from the internet. Therefore, the security team needs to be aware of unauthorized software being installed on their IT systems. Let's look as some of the problems that are posed:

• Unauthorized software: The symptoms of someone using unauthorized software is that the internet bandwidth is increasing while the disk space on the IT system is reducing. One of the best ways to stop this from happening it to use an application whitelist where only approved applications can be installed.

• Baseline deviation: When we roll out an image to the desktops, we know that they have the same baseline, but we need to ensure that we run a baseline visualizer tool that can detect the changes to the original baseline. We could also use a manual method of baseline comparison on a regular basis.
• License compliance violation: The company purchases 10 licenses for an application and then installs it onto the approved desktops. When another member of the company manages to steal the license key and puts it in his desktop, the company has violated the license agreement and the company could face a regulatory fine. We could prevent this violation by installing the software on a share and limit the number of people using the share to equal the licenses that we have purchased. Another license violation would be for someone to install a cracked copy of software on a company's desktop. We could prevent the installation of unauthorized applications by implementing application whitelists.
