Mobile technology and the digital age have already taken over the world. Many people use mobile devices. They are doing various random activities with their mobile devices, such as surfing the web, connecting with friends on social media, playing mobile games, or interacting with mobile apps.
Mobile devices are now more popular than desktops and laptops. The demand for mobile apps is increasing due to this growth. Mobile apps have become a part of daily life for many mobile users, as they are easy to use and convenient.
As mobile apps have grown in popularity and the demand for mobile app development has continued to increase, many are now vulnerable to attacks.
Many attacks have targeted some of the most popular mobile apps, including those that perform financial transactions, upload sensitive data and link with personal information. It is your responsibility as an mobile app developers to ensure that the mobile app you create will not compromise the security of your users.
Here are ten ways to ensure the safety of your users and your app's credibility.
What is mobile application security?
A mobile app strategy enforces security measures to prevent hackers and malware. Mobile device security has become an absolute necessity.
You must follow a security checklist before publishing an app online. Hackers could also access personal information, bank information and other details. Users use mobile applications to perform sensitive transactions, such as online banking or shopping.
Users may leave behind sensitive data, such as credit card numbers, personal information, bank statements, and financial statements.
These sensitive data expose users to external threats. These sensitive details are vulnerable to cybercriminals if they are not stored securely.
When we speak about mobile app safety, we refer to the steps we need to take to protect mobile apps from hackers and safeguard sensitive data from being accessed. Most developers do not pay much attention to security until a breach occurs. It may be too late, as a security breach can compromise sensitive data or result in hefty costs.
Real stats on mobile app security
Security concerns have become a daily challenge for businesses due to global pandemics. Recent research found that many companies don't protect their data or have poor cybersecurity practices.
This leaves them vulnerable to data breaches.
These surprising statistics show why mobile app security is important for businesses.
- Apps are used by 90 per cent of the world's 5,19 million smartphone owners. The economy is the main source of revenue for organizations. Many organizations do not take adequate security measures.
- After an unprecedented year in IT and security, remote access will become more commonplace. In two-thirds, sensitive files are publicly accessible in 1,000 or more companies. A financial services employee has access to over 11 million documents.
- In 2019, almost half of the organizations sacrificed their mobile security. Their apps became vulnerable because they prioritized market time over security.
- The FBI has warned consumers of mobile app fraud. Mobile banking has seen a boom since the Coronavirus lockdown. Trojan horses, fake applications, and other financial vulnerabilities in apps have increased by 50%.
- Researchers predict that by 2024, the global market for information security will reach $170.4 Billion.
- A growing number of businesses consider cybersecurity a risk. The advancement of technology has led to a 68% increase in security risks.
Statistics show that implementing incorrect technologies can lead to severe losses in business. You should figure out how secure your app is before hiring an app development company.
Mobile App Security: The Solution to the Problems
Mobile app security is not just a concern for users. Also, mobile app development companies and developers could be the victims.
With proper security measures in place, these issues can be resolved.
- Data Leakages
Mobile apps with weak firewalls are more vulnerable to data breaches. Statistics report that 2017 saw a record-breaking number of data breaches.
In 2018, the number of breaches reached a peak. The number of breaches has decreased since then, but mobile apps are still vulnerable to leaks.
- Infrastructure Exposure
Developers who fail to pay attention to the Application Programming Interface (API) integration can easily compromise server-level security and user data storage.
This threat is more prevalent on websites. Infrastructure exposure has caused major issues for big names like Yahoo, Apollo and Facebook.
- Financial Fraud
Fraudsters will target any mobile app that performs financial or banking transactions. Online frauds are on the rise, and mobile applications are not immune.
- Guidelines
All mobile applications should be operated within a legal, ethical and social framework. Users are more susceptible to cybercrimes, such as identity theft, spoofing and phishing.
Tips for Securing Mobile Applications
BYOD (bring your device) is a growing concern in the mobile app world. On their mobile devices, workers combine personal and professional interests.
We will now examine some tips and methods app developers can use to protect their mobile apps from security threats. These eight tips can help you create a mobile app that is hacker-proof:
Encryption Of Source Code
The majority of code in native mobile apps is on the client side. Mobile malware can therefore find bugs and vulnerabilities in the code.
Hackers compromise popular apps by reverse engineering them into rogue apps. These apps are then uploaded to third-party stores to lure unsuspecting customers.
This type of threat can damage the reputation of your company. Developers should be aware of security vulnerabilities when creating apps.
Ensure your mobile app is secure against attacks such as reverse engineering, tampering and eavesdropping. By encrypting the code, you can prevent these attacks and ensure that your data is protected.
You do not need to worry as a developer of mobile applications about the integrity and security of your product.
You must purchase a code-signing certificate to ensure that your app is delivered without any alterations by hackers. Apple and Android operating systems have placed a high priority on code-signing certificates. Code signing certificates allow app users to verify the source and authenticity of the code and let them know that an application is authentic.
The code signing certification will shrink-wrap the application, making it difficult to edit maliciously. Like other digital certificates, the code signing certificate gives users confidence and trust when using your application.
It gives developers all the security needed to protect their mobile apps. Developers have no choice but to purchase a code-signing certificate for the highest level of app security. You can work with a code signing certificate from Certificate Authority, which is reliable and affordable.
Penetration Testing
Mobile penetration testing is an important security practice that every developer must perform before releasing their application.
Mobile penetration testing is a way to evaluate vulnerabilities in software, apps, and operating systems. The developer can use automated or manual techniques to analyze the app and find loopholes that could allow attackers to gain direct access to the application.
The mobile app penetration test will reveal and eliminate flaws in the application. Conducting penetration testing has as its primary goal to ensure no major defects in the application.
Penetration testing is usually part of a more comprehensive mobile app threat assessment process. Developers must test all aspects of the app, including architecture, mobile app design and network communication. They should also check for privacy issues, misconfigurations, and other errors.
Developers must fix any problems that arise before the app is released.
Finding vulnerabilities is easier when you test from the hacker’s perspective. You can now identify the possible weakness that an attacker could exploit.
Testing for penetration includes:
- Checking password policy.
- Data that is not encrypted.
- Access to applications from third parties.
- Passwords do not expire.
Regular penetration testing will ensure that hackers cannot exploit any loopholes. Loopholes can become vulnerabilities, allowing hackers to access services and data.
Authentication at a High Level
The absence of strong authentication leads to security breaches. Apps should only accept passwords that are alphanumeric.
Users must also change their passwords frequently. You can protect sensitive apps with fingerprint or biometric authentication. Encourage users to authenticate to prevent security breaches.
Passwords and other identifiers are used for user authentication. Weak authentications have caused some of the largest breaches.
App developers should insist that users use unique and strong passwords to access their applications. Most cybersecurity experts have stressed that strong, unique and complex passwords are essential. A recent survey found that weak passwords caused 53% of breaches.
Users of apps should be forced to create long passwords that contain a mixture of characters. Developers should also not allow an app to store passwords, as this could compromise the application's security.
Developers can use two-factor authentication to improve the security of mobile apps further. The app user will have to provide additional authentication information in addition to the username and password. Users can access their apps using biometrics, secret codes, or code words.
This app security feature can be used in many ways, as unauthorized parties always miss the second authentication factor.
Protect Data In Transit
It is vital to prevent security breaches that sensitive information be transmitted securely. It is highly recommended to use a VPN or SSL tunnel.
To protect user data, stricter security measures have been implemented.
Use the Temper Detection Technologies
If an attacker can access your source code, they will try to modify it to gain access to your sensitive data. To combat such practices, implementing a robust tamper-detection mechanism is best to prevent code from functioning if it's been altered.
App developers should adopt this measure to alert them if someone attempts to inject malicious code or modify it.
Backend security
Most mobile applications use client-server. To prevent malicious attacks, a secure backend is essential. The APIs, according to developers, are usually only accessible to apps that have been specifically designed to use them.
It would be best to run API checks on each API you plan to use. Platforms may have different authentication and transport mechanisms.
The majority of mobile apps use a client/server model. Developers must use adequate security measures to protect backend servers from malicious threats.
Most developers believe only programs programmed to use the application programming API can access it. This is not always the case. It would be best to verify that all applications' interfaces are compatible with the platform for which you plan to code.
The application programming interfaces and transport mechanisms can vary greatly from one platform to another.
Reduce sensitive data storage
Developers store sensitive data in devices' memory to protect it from users. Due to security concerns, sensitive data is not recommended to be stored.
If you can't store your data in any other way, use encrypted data containers or key chains. Use the auto-delete function to minimize the log. The log will be deleted after a certain period. Developers are concerned about the security of mobile apps because they fear malicious behavior.
Users are reluctant to install unreliable applications. The above best practices should help you develop secure mobile apps.

Create an Effective Backup and Restore Strategy
Technology is evolving at an accelerated pace. Attackers find clever and sophisticated ways to steal sensitive information from users by infiltrating mobile applications.
Even the above tips and measures do not guarantee complete security against hackers. Attackers may eventually find a loophole in your security system and launch a destructive attack to tarnish your application's reputation.
Backup and restore plans can protect you from the devastating effects of a successful hack on your mobile application.
You can rely on the files from your backup to ensure continuity in case things don't go well. Hire a Mobile app developers which should encourage users to back up their data more often and store it in an alternative location.
Take advantage of the most advanced cryptographic techniques
Despite their popularity, MD5 and SHA1 do not meet security requirements. To ensure security, staying up-to-date on the latest encryption techniques is important.
Encrypt sensitive information using AES with 512-bit encryption, 256-bit encryption, and SHA256 hashing. Manual penetration and threat modeling can help ensure your application is secure.
The latest cryptographic techniques are another great way to protect mobile applications against security threats and vulnerabilities.
Even the most popular cryptographic algorithms, such as MD5 and SHA1, have not been able to keep up with the constantly changing security landscape.
Therefore, using the most recent cryptographic methods is always recommended. Modern encryption algorithms, such as AES and its 512-bit encryption strength or 256-bit cryptography, are the perfect solution to new mobile app security threats.
It would be best to remember to keep the keys in a safe place. Keep your cryptographic keys in a secure container and not on your device.
Encrypt your database and files
To ensure confidentiality, unstructured data will be stored on a local server. The data in the Sandbox is not properly encrypted.
This creates a serious security hole. You can use SQLite Database encryption modules to encrypt data from mobile apps in a sandbox. You can also implement file-level cryptography between platforms.
Use the Principle of Least Privilege
In cyberspace, the principle of least privilege should be followed. This principle states that a person should only be granted the privileges necessary to complete a task.
The principle states that an app or code should run only with the permissions necessary to perform its function. This principle is also relevant in other IT aspects, such as user systems, processes and networks, or applications.
It is best to deny the application access to data resources if it does not need to use different data sources or functionalities, such as contacts, sensitive data, photo galleries, location, network connections or contact information.
This principle reduces the impact of data leaks in a significant way.
How to Develop a Secure Mobile App
Develop Like A Mobile App Attacker
Always keep an attacker's mindset in mind when building your mobile app. You can ask questions to help you secure your app.
For example, if it is easy to hack the app or if you can exploit the app. You should always fortify your mobile app, no matter how minor the problem is. Cybercriminals or hackers can use any minor vulnerability to access your application.
Code reviews can help you eliminate any potential attack. Spend some time examining the app to see any possible attacks. Be sure also to fix any apparent flaws that you may find in your mobile application.
Work with your security team from the beginning
It is not possible to build an app in one step. Planning, research, brainstorming, and building prototypes are all part of the process.
Include security in all stages of your app development. From the beginning, your security team should be involved in all phases of mobile app development. Ask your security team for their opinion on the best way to secure your mobile application.
Always conduct tests and more tests
You must test your mobile app to ensure it can withstand all possible attacks. According to a recent survey, 60% of app developers do not feel confident in the security of their apps, but they still don't take any action.
As a responsible developer of mobile apps, you should conduct numerous tests to ensure that the security foundation of your app is solid.
Beware of Third-Party Security Loopholes
It is okay to use third-party codes, whether free or paid. However, these codes may not be safe. Many developers avoid this as much as possible.
You should read customer reviews of third-party modules and thoroughly analyze if you need to use them.
Never Forget The SSL Certificate
Mobile apps without SSL certificates are vulnerable to hacking. This certificate is not present, which allows hackers to hack your app and intercept traffic.
They can then perform a fake log-in, redirecting users. Most apps fail to implement SSL validation, making them vulnerable to man-in-the-middle attacks. For this reason, you should ensure that your app uses SSL certificates to create a secure connection between the user and the server.
Include User Authentication In Your App
The first line of defense is to require your users to create a password when accessing your app. Many users forget or create weak passwords, making it easy for hackers to crack logins.
Implement two-factor authentication in your mobile app to solve this problem. If you're developing a mobile application that will be used to conduct financial transactions, store confidential data or require confidential information, it is important to verify the identity of users.
Add 2FA elements such as random codes, which users can access via their registered mobile phones or emails. Add a retina or fingerprint scan to your app's login process.
Review Your API
APIs are essential to backend development, but they can be a security threat for most developers. Verify that your API or Application Programming Interface is safe using the mobile platform to build your app idea.
Encrypt the data required by your device
Storing personal or confidential data on an app can be a recipe for attack. If you must collect confidential data, ensure that the app is secure.
This can be done by encrypting any sensitive data on your device. You should not compromise the data that your app user experience has given you. Take the time to research and determine the best location to store your data.
It will be beneficial to you and your app from a security perspective in digital products in a wide range.
Reduce Permissions
Avoid granting too many permissions on your app. Do not request access to the camera if you don't need it. Ask permission if your app doesn't use contacts.
Every permission that your mobile app requests is another possible vulnerability. Zero-trust security should be the goal when designing your mobile application according to customer satisfaction.
Create a Secure Code
Most attacks on mobile apps begin with the code you wrote. Hackers and attackers will look for weaknesses in your code and then use that to crack into your app.
Keep your code secure and hard to crack. It should be incomprehensible to prevent reverse engineering. You should also design your code to be easy to patch and update, even by your users and target audience.
Final Thoughts
You can also do many other things to make your app more secure. Implement it. Assuring security at every stage of mobile app development protects your users as well as the reputation of your app.
This will protect your credibility as an app developer.
Mobile application security has increased in recent years. Application security compromises can have disastrous consequences for users and application developers.
Several measures are available to ensure secure application development. One of the best techniques is to train the product team on security. Effective team communication and penetration tests will advance the software development process.
