It was just recently announced that Apple will no longer be supporting QuickTime for Windows. Just like any other software, when support has ended, the software becomes a security risk. As a matter of fact, there are current known vulnerabilities in QuickTime that will never get patched. The Department of Homeland Security has an alert recommending removal of QuickTime for Windows.
For users, it may seem simple: Uninstall QuickTime from your Windows system. But wait.. what about software they rely on that may require quicktime? There are times when our users are locked into some technologies because of the software we create. How does our decision to use a specific technology have an effect on our end users when it comes to security?
If you have created an application that relies on the installation of QuickTime for Windows this creates somewhat of an issue. It can be very difficult to justify your position to end users to continue using a component that is not only known vulnerable, but is also past the end of life. This brings up a few things to consider when using third party components in our solutions.
Why use the component/technology?
The first question to ask is why do we need this component or technology. Is this a small feature within our application or does our entire business model rely on this. What benefit are we getting by using this component. Are there multiple components by different sources? What process was used to pick the used component? Did you look at the history of the creator, the reviews from other users, how active development is, etc.? When picking a component, more is required than just picking the one with the prettiest marketing page.
How do we handle Updates?
The number of breaches and security vulnerabilities documented is at an all time high. You need to be prepared for the event that there are updates, most likely critical, to the component. How will you handle these updates. What type of process will be in place to make sure that the application is compatible with all of these updates so the user is not forced to use an out-dated version? What would you do if the update removed a critical feature your application relies upon?
What if the component is discontinued?
Handling the updates and patches is one thing, but what happens if the component becomes end of life? When the component is no longer supported there is a greater possibility of security risks around it that will not get fixed. In most situations this will probably lead to the decision to stop using that component. I know, this seems like something we don’t want to think about, but it is critical that all of these possibilities are understood.
We use components in almost any software that we create. We rely on these components. Taking the time to create a process around how these components are selected and how they are maintained will help reduce headache later on. We often focus on the now, forgetting about what may happen tomorrow. Take the time to think about how the component is maintained going forward and how it would effect your business if it went away one day. Will you ask your users to continue using a known vulnerable component, or will you have a plan to make the necessary changes to no longer rely on that component?
