Mobile-app security breaches can harm the entire operating system, so ensuring mobile app security from data theft is essential. Identifying a threat in mobile apps and defining their security level is not easy. However, with company reputation and users' personal information at stake, mobile app developers must do everything in their power to keep mobile apps secure.

1. Mobile phones have become a major part of our lives, surpassing the popularity of desktops and
laptops. Companies these days are adopting a mobile-first approach while designing and
developing applications because a large number of mobile users spend 90% of their time on
mobile apps. Therefore, it is very important to consider mobile application security and ensure
that users' sensitive details are safe.
Mobile-app security breaches can harm the entire operating system, so ensuring mobile app
security from data theft is essential. Identifying a threat in mobile apps and defining their
security level is not easy. However, with company reputation and users' personal information at
stake, mobile app developers must do everything in their power to keep mobile apps secure.
When consumers make online purchases or banking transactions, they leave a digital footprint,
such as their personal name, street address, phone number, and banking information.
This highly sensitive data optimizes the user experience. However, sensitive data also exposes us
to external threats such as hackers if the data is stored insecurely. So, when we talk about mobile

2. application security, we mean the steps we take to secure applications from external threats that
don't give hackers the ability to access personal, financial information, and confidential data
remotely or from lost and stolen devices.

best practices to safeguard mobile applications, continue reading.
Top 10 Mobile App Security Best Practices for Developers :
Below are the Top Mobile App Security Best Practices by the top 10 mobile apps
development companies in NYC Recommended for Developers.
1. Start from scratch:
‘Mobile app security is not a sprint, it's a marathon.’ When you think about and implement
security from the start of your development, you leave less room for expensive, time-consuming
fixes. Keep a safety checklist handy and, if possible, assign safety duties to someone who
oversees it.
2. Entrance Test:
Increasingly, testing methods like SAST (Static Application Security Testing) are becoming
mandatory for IT organizations. SAST tests break into your source code and identify tiny
security flaws. There are many tools you can use to perform penetration testing of your app.
3. Code Signing Certificate:
Code signing certificates provide a digital signature that an app development company in
San Francisco uses to sign software or code to ensure that the user has not tampered with the
code. This assurance gives the user the impression that the code is from a genuine publisher and
the mobile app is safe to use and download. Once the app development is complete, your code
will be encrypted and any malicious party will not be able to cheat your users by spoofing your
app. By publishing the developer's name, end users can know that the app is genuine and not
tampered with.

3. 4. Be careful while using third-party libraries:
We know how much you want to use third-party libraries, but before you do, you should test
your code extensively. There have been quite a few incidents in recent times that have caused
some serious trouble due to insecure third-party libraries. So, be careful!
5. Safe and agile code:
Now you might say this is another cliché point. But try to understand a little from our point of
view. An article on app security would be terrible if it didn't tell you to keep your code secure.
Making your app secure should be your first priority in development.
6. Secure client-to-server communication:
Not only stored data but also data-in-transit must be secured to prevent man-in-the-middle
(MiTM) attacks. To secure server communication, you have two options. You can go with SSL or
VPN tunnel. However, with everything in mind, we recommend that you go with SSL/TLS.
7. Encrypt data:
We cannot stress this enough. You must encrypt every bit of data transferred to the user's
phone. This way, even if a hacker gets his/her hands on his/her data, he/she cannot use it. And
of course, use unbreakable protocols like 256-bit AES encryption.
8. Strong Authentication, Session Management, and Authorization:
When it comes to mobile app security, authentication and authorization are two of the most
critical aspects. Developers must ensure that end-user passwords are highly secure, and they
must also enable multi-factor authentication. If the app deals with highly sensitive information,
the user must be logged in for each new session. Every developer should implement the OAuth
2.0 authorization framework or OpenID Connect protocol by using their current versions.

4. 9. Your app should know as little as possible:
At least under the principle of privilege, an app should ask for the data it absolutely needs. Don't
make your app request access to messages if you don't need them. Keep your access to a
minimum.
10. Constant App Testing and Regular Updates:
No platform is 100% secure. A closer look at each stage leaves some dark spots. That's why app
testing should never stop. If you can afford it, you can even start your own bug bounty program.
11. Minimize storage of sensitive data:
It is recommended that you as a developer do not store sensitive data in the device's local
memory as it is highly vulnerable. If you have no choice but to store data, do it in encryption
containers or key chains to keep them safe. Also, implement the auto-delete option, which
deletes data after a certain set period of time.
Conclusion:
People continue to rely more and more on their mobile phones. With all their functionality, they
are an indispensable part of our lives, so it is important that we treat mobile application security
and thus our data with the utmost care.
Understanding the potential risks from security issues and learning the right methods to secure
your phone is key to ensuring mobile application protection. Secure coding practices,
continuous security testing, penetration testing, and a focus on positive user experiences can
greatly increase security.
