A Complete Checklist to Build a Secure Mobile App

Today, it’s hard to imagine our lives without mobile apps. One thing or the other is done by using them. They have completely revolutionized our shopping cultures, banking habits, and socialization practices. But with the convenience of mobile apps comes the responsibility of ensuring they are secure. A secure mobile app protects user data and forms credibility. Here’s a complete checklist to build a secure mobile app to succeed in your development business.

Secure Code Formation

The foundation of any secure mobile app is its code. Your app’s code is the first line of defense against cyber threats. We suggest you follow the below practices for a secure code formation.

Write Clean & Efficient Code

Start by writing clean and easily understandable code. Please avoid using unnecessary code that might open up vulnerabilities. These things matter the most, especially when you have a heap of codes.

Minimize Third-Party Libraries

While third-party libraries can save time, they can also introduce security risks. Use them less, and be sure they are from trusted sources.

Obfuscate Code

Thinking about Code obfuscation? It is something that is a nightmare for the app attackers. It reverse-engineers your app’s code. This adds an extra layer of protection by making the code harder to understand.

Regularly Update Code

Cyber threats are evolving – so it’s crucial to regularly update your code to address new vulnerabilities. These mobile app security best practices & tips can help you a lot in securing your app.

Execute Strong Authentication

You know authentication, right? It verifies the identity of a user. Weak authentication methods can leave your app vulnerable to attacks. Look below to learn how you can strengthen your app’s authentication.

Use Multi-Factor Authentication (MFA)

MFA requires users to provide two or more verification factors to gain access. This is what they say about MFA – something they know (password), something they have (a mobile device), or something they are (fingerprint).

Strict Password Policies

Require users to create strong passwords with letters, numbers, and special characters. Discourage the use of common passwords. This is a mobile app security checklist one of the most common yet dangerous vulnerabilities.

Session Management

Put secure session management active to prevent session hijacking. Set session timeouts and use secure tokens to authenticate user sessions.

Encrypt All Data

Encryption is a critical aspect of the mobile app security checklist. What it does is that even if data is intercepted, it cannot be read or tampered with. Here’s what you need to do:

Encrypt Sensitive Data

Encrypt all sensitive data, both at rest & in transit. It has to do with personal information, login credentials, and financial data.

Use Strong Encryption Protocols

Be sure you use robust encryption protocols such as AES (Advanced Encryption Standard) to protect data.

Secure Communication Channels

Use secure communication channels like HTTPS to encrypt data in transit and prevent man-in-the-middle attacks.

Secure Backend Servers

Your app’s backend servers are just as important as the app itself when it comes to mobile app security. If your servers are compromised, your entire app could be at risk. This is how to secure your backend:

Use API Security

Secure your APIs with tight authentication and encryption methods. Use tokens for API authentication and limit API access based on user roles.

Regular Security Audits

Conduct regular security audits on your servers to identify and fix vulnerabilities. You can use automated tools to scan for potential threats. This works!

Keep Servers Updated

Be sure your backend servers are always running the latest software versions and security patches. Attackers can easily target outdated software. That’s a piece of cake. You know the moral, right?

Use Secure Data Storage

You must store user data securely to protect it from unauthorized access. That’s how you handle data storage securely:

Avoid Storing Sensitive Data Locally

Avoid storing sensitive data like passwords and credit card information on the device. If necessary, you can use secure storage options provided by the operating system, such as Android’s Keystore or iOS’s Keychain.

Encrypt Stored Data

If you must store sensitive data, ensure it’s encrypted. This way, even if the device is compromised, the data remains protected.

Enforce Data Access Controls

Restrict access to stored data to only those components of your app that absolutely need it. The risk of data exposure decreases.

Test Your App Regularly

As you know, testing is critical for building a secure mobile app. Regular testing helps identify vulnerabilities before they can be exploited. Here’s how to approach testing:

Conduct Penetration Testing

You can do penetration testing to check how real-world attacks work on your app. This helps you identify and fix security gaps.

Use Automated Security Tools

Integrate automated security testing tools into your mobile app development process. These tools can continuously scan your app for vulnerabilities.

Perform Code Reviews

Regularly review your code for security flaws. You know what? Peer reviews catch even those issues that tools can’t. So, do it!

Test for Platform-Specific Vulnerabilities

Different platforms (iOS & Android) have their own security challenges. You must test your app for vulnerabilities specific to each platform. Keep your application security checklist in check.

Secure Third-Party Integrations

Many mobile apps rely on third-party services & integrations, such as payment gateways, social media logins, and analytics tools. While these services add functionality, they can also introduce security risks. Read the below points to learn how to manage third-party integrations securely.

Choose Trusted Providers

Only integrate with third-party services that have a strong reputation for security. Research their security practices and read reviews from other developers.

Review Permissions

Limit the permissions you grant to third-party services. Only allow access to the data and functionality they need to operate.

Monitor & Audit Integrations

Regularly monitor third-party integrations for unusual activity. Conduct audits to ensure they continue to meet your security standards.

Today, AI integration services are becoming increasingly popular. So, if you get AI services, be sure to get them from reputed AI service providers like Provis Technologies.

Secure App Distribution

How you distribute your app can impact its security. If the distribution process isn’t secure, your app could be tampered with before it reaches users.

Use Official App Stores

Distribute your app through official stores like Google Play and Apple’s App Store. These platforms have security measures to prevent malicious apps from reaching users.

Sign Your App

Use a code-signing certificate to sign your app before distribution. This helps verify the authenticity of your app and ensures it hasn’t been tampered with.

Provide Clear Updates

When releasing updates, clearly communicate what’s new to your users. This helps them trust that the update is legitimate and not a potential security threat.

Educate Your Users

No matter how secure your app is, users can still be the weakest link if they are not educated about security. This is how you can tell your users about how they can protect themselves online.

Provide Security Best Practices

Include security best practices in your app’s onboarding process. Teach users how to create strong passwords, recognize phishing attempts, and keep their devices secure.

Encourage Regular Updates

Encourage users to regularly update your app. Updates are important because they have security patches that keep new threats at bay.

Offer Two-Factor Authentication

Where possible, offer two-factor authentication as an option for users. This adds an extra layer of security to their accounts.

Know Security Trends

The world of cybersecurity is constantly changing, with new threats coming up all the time. Staying informed about the latest security trends is essential to keeping your app secure.

Follow Security Blogs & News
