How to Protect Your Mobile Application Against Cyber Attacks

— April 26, 2021

It is important to remember that preventing significant cyber threats from attacking your smartphone apps is more appropriate a strategy than combating them.

Let us not forget that there are close to 5 million apps on the Apple App Store and Google Play Store together. The explosive growth of mobile apps is also giving birth to new and newer security risks. Naturally, app developers are always on the lookout for tested and tried means to protect their apps from cyber attacks.

Let us explain here some of these tried, tested, and reasonable means to safeguard your apps from cybersecurity threats.

Optimising Code

To ensure optimum app security, app developers must always use a highly secure framework for building the application. This will help them avoid most of the coding errors. The coding errors and design faults can allow the attackers to get easier access to app data. This is why developers need to consider security aspects just like a hacker.

On top of this, the developers also need to protect the apps with Runtime Application Protection to ensure most minor exposure to cyber-attacks in actual time. It is also advisable to hire a third party to hack the app and nullify all the possible attacks. Many app developers Ireland use code optimisation as their preferred measure to improve app security.

Stringer User Authentication

Secured authorisation and user identification are essential for app security. To enforce stronger protection, it is always advisable to make it mandatory for users to use an MFA (Multi-Factor Authentication) or 2FA (Two-Factor Authentication). These security protocols undoubtedly offer an extra security layer. 

Enforcing quicker session timeout after every minute of inactivity is crucial to safeguard a mobile app from live threats. Faster timeout is already a good security measure, and that is why most mobile banking apps extensively follow this security best practice.

Protecting the App Backend

Another crucial security measure is to protect the app backend. To help backend security, it is essential to strengthening the server security. Extra protection can be implemented by testing all the APIs responsible for accessing the servers. Apart from that, some procedures such as data encryption, penetration testing, and data containerisation can also be beneficial.

Ensure optimum API security

APIs are responsible for bringing third-party services to a mobile app, and that’s why they have higher exposure to security risks. Make use of the 256-bit SSL encryption To help APIs securely transit data. This will at least give full security to the data in transit.

Security by design

Another important step is to design a model for the threat perception in the very beginning. This will help you to think like a hacker and evaluate the threats from the perspectives of the hackers.

Lastly, whether you are creating safeguards for your online store app or any other regular app, always consider all the consequences that are likely to happen if a security breach occurs.

Mobile device management

Since the mobile app ecosystem is too diverse and segregated across hundreds of different devices, several dozen OS platforms and their versions, device management is vital.

To control unwanted access to the app, it is essential to embrace the 256-bit Advanced Encryption Standard and ensure optimum data safety, whether in files, forms, and other data sources. Maintaining a robust encryption key management strategy is also very important from the security perspective.

In Apple iOS, you have several different mobile device management (MDM) or enterprise mobile management (EMM) solutions like MobileIron, MaaS360, Good Technology, etc. Another less expensive security option is to use the Microsoft Exchange ActiveSync protocol.

Android smartphones, in contrast, represent bigger challenges. Thanks to their low price point, they are more accessible and hence attract security breaches more frequently than others. As a tool, you can use Android for Work (A4W), an enterprise-grade solution for encrypting device data and segregating personal and professional apps.

App Wrapping

App wrapping is another highly credible security enforcement measure for mobile applications. This type of security measure is popular because they are the least likely to change its app functionalities and look. Thanks to this wrapper, there will be stricter rules about accessibility and the people who can download the app, the APIs to be allowed, etc.

Highly Protected Payment Transactions

Most mobile apps facilitating transactions are vulnerable to threats corresponding to mobile payment. So, safeguarding payment transactions from online threats is extremely important from the security perspective. Online security against vulnerable transactions can be made stronger and robust by using multiple-factor authentication, data encryption, session management, cookie management, etc.

Make use of App Transport Security (ATS)

ATS or App Transport Security is a robust and handy privacy feature that Apple has brought from the iOS 9 update. ATS enhances the data integrity and boosts privacy for all types and app extensions of all kinds. On top of all these, ATS can also prevent connections lacking the least minimum security needs.

ATS comes with a powerful TLS configuration addressing the criteria such as allowing connections with servers by using TLS 1.2 protocol and strong cyphers and allowing server connections using PFS (Perfect Forward Secrecy) protocol.


In this respect, it is important to remember that preventing significant cyber threats from attacking your smartphone apps is more appropriate a strategy than combating them. For saving mobile apps from the menace of disastrous cybersecurity attacks, it is extremely important to identify potential security risks. It would help if you always went to the root of the problem instead of addressing security risks in a superficial manner.

Only when you detect the potential threats and vulnerabilities, preventing them or taking safeguards against them becomes more accessible. To ensure the strongest cybersecurity for your mobile app data, it is also essential to use a data backup tool.
