With the advent of technology, smartphones in the hands of the user are the most common object found today. Meanwhile, this rate of growth is quite opportunistic for mobile app developers to produce more secure environments for customers. Facilitating security to the mobile applications is a major concern for the users, specifically related to data.
Developers design security controls and embed them in applications to curb the vulnerabilities. Since the most casual users are on smartphones, that’s why it is a prime target for intrusive activities.
Hackers of all kinds are targeting applications of mobile so that they can get access to private information and crucial data. That’s why it has become a dire need for developers to inculcate security aspects while building particular apps for every platform.
Mobile App Securities Best Practices
This blog is about the top 10 security practices in mobile application development followed consistently by developers creating safe and secure mobile applications.
Write a secure code
Every hacker tries to get a public copy of the codes you write for your program. This copy allows them to easily manipulate and make changes in the program you have made. A survey reports that around 11.6 million mobile app developers get affected by hackers every instance.
So, writing a secure code is very much needed. Make sure to harden your codes from day 1 of your writing. Also, try to repetitively test the program to fix any bug present in the program.
Encrypt the Data
Encrypting data ensures that no one else other than you would be able to read the files. Without the key, it will be just random alphabets for the viewers, and they will not be able to extract any data from it.
In this way, even if the data gets stolen, it is protected from being misused. The power of encryption is well visible when secret agencies ask permission from company owners for decrypting iPhones.
Be careful while using libraries
Third-Party libraries are great to use. They not only help in improving the codes but also save time from writing very long codes. But sometimes, the use of these libraries exploits the security of the code.
A minor bug in the library would let hackers copy the program and extract valuable data from it. Make sure to minimize the use of these libraries or use only trusted ones. Also, ensure to test your application as many times as you can.
Use authorized APIs only
Loosely coded APIs or that are not authorized can accidentally grant privileges to a hacker to misuse the program gravely. Using APIs is helpful, especially if you are working on large projects, but caching this information can allow a hacker to enter the program and creates a loophole that can allow them to change their privileges. Central authorization for the API is beneficial to gain maximum security.
Use high – level authentication
A weak authentication can lead to an effortless breach in the program. In fact, most of the programs get affected due to ineffective authentication. As the number of hackers and tools is massively increasing, the necessity to use strong authentication is rising daily.
Authentication acts as a barrier between the data and the hacker. It can be a password, smart key, fingerprint, or any other means. It depends on the end-users depending on how well they manage their details. But it is also a responsibility of a developer to remind their users regarding the sensitivity of these authentications.
Develop Tamper Detection Technology
Some ways can disable the code or set an alert if someone tries to modify or tamper with your code by using malicious codes. Activating tamper-detection can ensure that if something like this happens, the program will not function properly. Nowadays, Apple uses this feature in their latest devices in which replacing any part can lead to malfunctioning of the device.
Provide the least privilege
Providing the least privileges means that the program must request only for those permissions that it needs to run and no else. Only those permissions that require the proper functioning of the program must be requested. In fact, the user must have the right to select which privilege they want to provide or which not.
It ensures the user’s safety as if any hacker attacks, only those data related to the app will be accessible, and other data will be safe. This increases the safety and helps in the smooth functioning of the app.
Deploy proper session handling
The management of sessions is essential while developing an app as the sessions on the mobile are longer than those on the desktop. Hence makes it hard for the server to handle it. Tokens can be beneficial in place of device identifiers for identifying a session.
They can revoke any time that makes them more secure and safe while being lost. Remote wiping and the log-off device can be helpful to prevent the data in case the devices get lost.
Use good cryptography tools and techniques
Management of keys is crucial when it comes to the encryption of your data. Never hard-core your key as it allows the hackers to attach onto the system and steal the data. Try to store the keys in secure containers and never share them even on the local network.
MD5 and SHA1 are two of the most used cryptographic protocols that do not fulfill modern security standards. So, it is prescribed to use the latest APIs like 256-bit AES with SHA-256 hashing.
Securing the app with modern features and tools is a never-ending process as daily advancements occur on both sides. Every day new threats or bugs happen that require a different solution.
So, invest more in penetration testing, threat modeling, and emulators where your app gets tested under every possible situation for vulnerabilities that need to fix. Fixing them with updates and security patches is very much necessary. Security plays an important role, and through proper testing, any new bug that appears can be found and fixed.
This blog contained a few best practices that the best dedicated developers exhaustively utilized to secure their applications. Currently, the importance of cybersecurity has risen and consumers are also looking forward to understanding security issues. In the same way, the users are looking for secure applications with the same kind of facilities.
In the coming time, security will be one of the most important parameters while deciding for any application to be used. The necessity of maintaining the privacy of data will become the primary objective of mobile applications.
