Whether for software design, for the Web, or for any of the popular desktop or mobile platforms, many developers do not consider how their design selections can affect security. their application.
Some bad design choices are made because of a time limit or the need to create a "user-friendly" application. Some bad design choices are due to the fact that developers only understand the security requirements of the application or because they depend on third-party partners for certain features of their application.
Below you will find an explanation of how each choice causes security problems. We will also explain how a software architect can avoid these security disadvantages. The mobile application development company is concerned about following things when designing a mobile application.
1. You do not use a secure design checklist
When many developers design and develop an application, they are working on developing an application to perform the task at hand. They usually work in the allotted time and, as the project progresses, security can sometimes become an afterthought, an issue to be solved once the application is properly performing its task.
Never approach software design with security as a secondary requirement, but still design the application with security as the primary requirement. Security is about understanding what problems you can solve and understanding the problems for which you can not do anything. A secure design checklist can help you achieve this goal.
The Microsoft Patterns and Practices site provides an excellent example of what a secure design checklist should include. Although Redmond has "removed" this list, it is nevertheless an excellent framework for creating your personal design checklist.
2. You can not think like a bad guy
Never forget that, no matter what type of application you develop, someone will probably attempt to hack your code. Whether for pleasure or for profit, someone is there to help you. It is also important to avoid the attitude of "This application is secure because I develop it and I can not hack it!" You simply do not approach the code from the correct (in) point of view.
Software security would be enhanced if every designer, developer and manager was more confident about the possibility than someone "wants to get them".
Try to secure the software with the same state of mind as a black hat hacker. Examine the code you develop with an eye on how design would create insecurities in your code. The feature you just added to recover the user experience can also enhance the experience of hacking.
Secure software design is essentially about guarding against attacks, exploits, and threats. Whenever possible, it's a good idea to use a hacker to look for faults in your application. Have them really pummel your code for security holes, and share how they exploited them.
3. You do not consider the attack surface of an application
Sliding features can be one of the most important contributors to the insecurity of any mobile application. Even though it would be nice to include every feature that you or your customer can think about, always approach the features from a security perspective before running additional features.
For example, although a search feature or a help feature is always suggested for any application, especially web applications, consider requiring a user to log in before activating it. these features. By limiting a help or search function to authorized users only, you limit the overall likelihood of an attack.
The attack of an application can also be increased using APIs or third-party services. A mobile app is as secure as making cloud service security or security related to the connection of your weakest partner. If the partners have security vulnerabilities, your application has security vulnerabilities.
4. You forget that small vulnerabilities represent a great vulnerability
By paying attention to small security flaws in your application, you avoid that they combine to create a hole big enough for a bad guy to drive a truck.
Small vulnerabilities may not seem important in the big diagram, but each unsafe "straw" adds weight to the back of your security camel. Hackers can take advantage of any security vulnerability and many have a real talent for linking enough vulnerabilities to create a huge number of problems.
When you design and develop your application, deal with small security issues and you will find that you will face far fewer security issues down the line.
5. You do not talk about future code exploits
Building security in your software from the beginning is the best way to guard against possible exploits that the industry is not yet aware of. The bad guys could even use two features that, in themselves, do not provide a foothold, but by combining, they could open a hole.
No application is ever really "finished". I have not yet developed or updated any software that does not require an update, it is necessary to fix bugs, to offer features or to repair the back. camel. Always incorporate security into all phases of your development, whether during initial development or bug fixes.
