Mobile App Security: 8 Steps You Should Take To Enhance It

Smartphone applications play a pivotal role in many aspects of our lives. We utilize them for everything: from managing our money to staying connected with those we care about. 

As the importance of these apps grows, the security requirements around them also escalate. In December 2022, there were over 2.2 million mobile cyber attacks worldwide. One minor security flaw can put millions of user’s personal information at risk. 

It’s crucial for tech enterprises and app creators to grasp and integrate top-notch security measures. Let’s dive into eight crucial steps to beef up your mobile application’s security.

Why is Mobile App Security Important?

Protecting User Data

At the core of every application lies its user base and their data. This includes everything from names, places of residence, bank specifics, memorable photos, to contact numbers. In many ways, our apps might know us better than some of our friends. 

If there’s a security lapse, malicious entities could gain unauthorized entry to such data, exposing users to potential financial scams, identity theft, or worse. By installing rigorous security protocols, users’ private details remain confidential, building a foundation of trust.

Maintaining Brand Reputation

In our current age of rapid information dissemination, one security oversight can severely tarnish a brand’s image. A brand’s reputation, built over several years through dedication and hard work, can crumble within moments. 

Users must feel that their information is in safe hands. Any breach shatters this belief, often resulting in an exodus of users, negative online chatter, and unfavorable media coverage.

Regulatory Compliance

Certain sectors, particularly those like finance and healthcare, operate under rigorous data protection norms. Inadequate security measures can lead to breaches of these standards, translating to substantial fines and potential legal proceedings. For example, regulations such as Europe’s GDPR lay out comprehensive data privacy clauses to be followed by a mobile application development company.

Safeguarding Intellectual Property

For several organizations, their mobile applications are a reflection of substantial investment in research, innovation, and proprietary strategies. The absence of robust security can expose proprietary methodologies, unique features, or innovative processes. Competitors might reverse-engineer or replicate them, ruining a firm’s unique market standing.

Evolution of Cyber Threats

Cyber threats aren’t static. They are in a constant state of evolution. As technology races ahead, cyber hackers craft more ingenious methods to exploit weak spots. 

Mobile applications, owing to their extensive user base and the treasure trove of data they manage, are prime targets. Hence, it’s imperative for those behind these apps to stay proactive, with a laser focus on security.

Key Steps To Enhance Mobile App Security

Threat Modeling

Before you jump into the actual development of your application, it’s crucial to understand what you’re up against.

  • Identify potential threats: Think like a hacker. If you were trying to gain unauthorized access or disrupt the service, how would you do it?
  • Determine vulnerabilities: Look into the architecture of your app. Where are the weak spots? Which parts of the app handle critical data?
  • Plan countermeasures: After identifying risks and weak links, devise a plan to tackle them. This might mean redesigning certain elements, deploying particular tools, or tweaking your app’s operation.

Secure the Code

The app’s code is the first line of defense. Ensuring it is robust and secure can prevent a significant portion of potential attacks.

  • Minimize code complexity: The more straightforward your code, the fewer weak points it will have. Maintain uniform coding standards and skip needless additions.
  • Regular code reviews: Make it a habit to inspect the code for any weak spots. Automated tools are great, but the human touch in reviewing shouldn’t be ignored.
  • Mask and Minimize: By making your code tricky to interpret and modify, you safeguard it further. Every professional mobile application development company uses this approach.

Secure Data Storage

Mobile devices can be lost or stolen, and when that happens, you don’t want your app’s data to be readily accessible.

  • Encryption: Encrypt sensitive data both in transit and at rest. Make use of encryption algorithms that are widely accepted and tested.
  • Limit Data Storage: Ideally, avoid keeping sensitive info on the device. If unavoidable, encrypt it securely and consider its retention duration.
  • Extra Protection Layer: For highly confidential data, think about using fortified containers.

Use Strong Authentication and Authorization

Ensuring that only authorized users access the app and its features is crucial.

  • Multi-factor authentication (MFA): Encourage users to use a two-step verification process, ensuring a decreased likelihood of unwanted intruders.
  • Manage Active Sessions: If someone’s been idle for a while, make their session end automatically. A mobile application development company also integrates token-based checks and inactivity log-outs.
  • Determine User Roles: Not all app users need access to everything. Assign roles and permissions accordingly.

Implement Secure APIs

APIs are the gateways to the data and services your app uses. Securing them is crucial.

  • Use authentication: Each interaction via APIs should pass a validity check. No authentication, no access.
  • Limit data exposure: Your APIs shouldn’t be overly generous. They should share just the essential data that’s needed for their specified job.
  • Rate limiting: Too many requests? Put a cap on the number of times an API can be reached out to. This minimizes the chances of potential risks.

Ensure Secure Communication

Data transmitted between the app and servers is a prime target for attackers.

  • Use HTTPS: Make your app interact exclusively via HTTPS, encrypting the data while it’s in transit.
  • Implement SSL pinning: SSL pinning ensures the app communicates only with the designated server, eliminating potential man-in-the-middle attacks.

Regularly Test and Update

An app’s security is not a one-time task but an ongoing commitment.

  • Penetration testing: Periodically inspect your app for weak points, mimicking potential attacker strategies.
  • Update frequently: Keep the app, its libraries, and dependencies updated. New vulnerabilities are found regularly, and patches are released to address them.

Educate Users

The best security practices can be undermined by uninformed users.

  • Promote strong passwords: Guide users towards adopting long, unique, and challenging-to-crack passwords.
  • Regular updates: Stress the significance of timely app updates. Perhaps use in-app alerts for urgent upgrades.
  • Teach about risks: Use in-app tips or links to educational content to inform users about potential security risks and how they can avoid them.


Ensuring your mobile app’s security is a multifaceted challenge, weaving together processes, attitudes, and technical efforts. A thorough approach, starting from initial designs to after-launch revisions, can significantly cut down breach risks and boost user confidence. Remember, in today’s interconnected world, security isn’t a mere add-on – it’s a necessity.
