Best Practices For Mobile App Security

Digital frauds are risking the financial and personal information of the people. It is very important to secure mobile applications from external threats like spyware, malware, phishing and gacking, etc.

The security you provide your customers is not just a feature or an advantage – it is a basic necessity for every business. One security breach can make your company lose its trust and reputation for its entire life. That’s the reason security should be given top-most priority from the moment you begin to write the first line of code.

1. Using Server-Side Authentication

One of the best practices to remove the security threats on the applications is Multi-factor authorization. After the server-side authentication is approved access to the data is provided. When the data is stored on the client-side server, proper authentication, and credentials should be adopted before offering access.

2. Using Best Cryptographic Algorithms

One of the best ways to prevent security threats is to use a cryptographic algorithm that shouldn’t be easily encrypted by hackers. Another best way to avoid a security breach is to avoid saving the passwords in the device. The encryption algorithms must encrypt the keys before they are transferred to the servers. Never ever try to use your own security protocols and must avoid using the algorithm which are disapproved by the community.

3. Validate Sanity Checks

To prevent the hackers from extracting any important information and adding malicious injection into the code, the developers must make sure that the application validates every input offered to it. For example, if the application requires to add an image of the user, the extension of that image must be of known image format, which should be easily accepted by the application. In this way, no hacker can add malicious code by justifying it as an image.

4. Build Threat Models

The developer should design a very well-informed threat model to ensure the safe and secure functioning of the application. It will be helpful for them to understand the problems and other issues related to it. This model can help to devise strategies to deal with other critical issues as well. A threat model should understand how different operating systems operate and how other functionalities work by transferring and storing data.

5. Code Obfuscation

Code obfuscation is the process of protecting applications by implementing techniques of code obfuscation. This process allows the developers to build a code that is very difficult to understand by the hackers. It involves removing the metadata and encrypting the entire code to stop reverse engineering and to rename the classes as well as functions to confuse the hacker.
