A particular problem that developers face when creating web apps is that users are notoriously lax in updating their software. A problem piece of software may make it easy for a hacker to gain access to the system. In some cases, the user will blame your application because it depends on software that could be outdated on the user’s system. A recent InfoWorld article, 10 old, risky applications you should stop using, brings the issue to light. Many of these pieces of software see use in Web apps. You may think that the user will rely on the newest version of the software, but the user may, in fact, have a piece of software that’s several generations old, yet runs your web app just fine.
Unfortunately, these types of problems come with the territory of creating a web app that you may use for business purposes, or otherwise. And because a problem like this can be so great, it needs to be taken into consideration before doing anything else. Of course, creating and developing a web app in the first place is just as important, and it’s a good job that places like Expedition Co. (https://www.expedition.co/services/development/web-app) are on hand to help anyone who is looking to create an external business tool service that can help to meet the needs of your business. Once this has been done, you need to resolve any problems that you have regarding the software that potential customers could be using.
The fear that many users have is that your web app will stop working if they upgrade to newer software. This fear has a strong foundation in broken applications of all sorts in the past. The problem can become quite severe. Looking at the InfoWorld article, you find several interesting bits of information. For example, many existing applications rely on Microsoft XML Core Services 4.x, despite the fact that the software is no longer supported and represents a huge security hole that hackers are only too happy to exploit. If the user removes this software to keep their systems safe, they may also have to give up on one or more mission critical applications. Testing is the developer’s tool of choice in this case. Make sure you test your web apps with the lasted software and then publish the results online. You could even get outside help from the likes of Cobalt, specialists in manual penetration testing, to route out any vulnerabilities the app may have. Keep users informed of potential problems and your plan for fixing them so that they can continue making required updates to keep their systems safe.
It may not be entirely possibly to fix every security problem immediately. The fact is that software today is so interdependent on every other piece of software that even when your web app has fully supported underpinnings, the software you depend upon may not. The dependencies cascade in convoluted ways that make it entirely possible that a hacker will find a way to breach your application despite your best efforts. Consequently, you not only need to maintain a firm grasp on testing, but also of potential problems with the software used to reduce your development effort and make the application perform better. In short, you need to have a contingency plan in place for those times when a hacker finds a way to break your web app because a determined hacker will find a way. I like to do lots of research on websites like Informit.com, before I buy or use any new software. If I read that something will slow my website down, I won’t use it. However, if I read that the software will benefit my website, I’ll go ahead and download it!
Outdated software is the bane of developers everywhere, yet users remain clueless as to how much damage they invite by not making required updates. One of the issues that I’m constantly striving to solve in my books is this whole concept of software dependency and how it affects application reliability, security, and speed. If you find that some of the materials I’ve put together are especially helpful (or possibly not helpful enough), please let me know about them at John@JohnMuellerBooks.com. I want to be sure that the security features of my books really do help you past the whole outdated software issue because users really won’t be much help at all.
