How App Developers Can Prioritize Cybersecurity for End Users

Prioritize Cybersecurity

Whether they’re downloading the latest smash-hit mobile game or using their browser to access a project management system for work, users expect their experience to be intuitive and safe. Mobile and web app developers can’t afford to neglect user security as a core feature throughout the development cycle.

The diversity and unique challenges of app development mean one-size-fits-all solutions are few and far between. Still, adopting several proven methods we’ll expand upon shortly can elevate user security, foster trust, and set your app up for success.

Adopt Secure Coding Practices

App and user security are fundamental to developing resilient, trusted apps. That’s why adopting a security-first mindset and strategizing what security measures to implement should be a priority, even in the early planning stages. Rooting your app’s development in cybersecurity trends best practices from the outset minimizes the vulnerabilities that will arise at later stages and streamlines progression.

Following secure coding practices means implementing safeguards against tampering while keeping the code clean and organized. You’ll want to pay special attention to enforcing input validation to prevent attacks like cross-site scripting and SQL injection. How error messages are handled is also a concern, as too much information can tip hackers who are posing as users off to exploitable vulnerabilities.

You’ll also want to keep the number of dependencies, third-party libraries, and other external resources to a reasonable minimum since you have no control over their development. Make sure you’re using their latest versions to prevent known exploits from infiltrating your app.

Encrypt Crucial Data

No matter how robust the security measures seem, no combination of measures is complete without data encryption at rest and in transit.

Given enough time and resources, tenacious hackers could discover and use vulnerabilities in your code, third-party integrations, etc., to steal the data your app stores or transmits. Encrypting that data protects its contents from exposure since the attackers have no means of decrypting it.

Encryption should be twofold. The stationery data the app collects should be protected by state-of-the-art encryption protocols that are highly resistant to attacks, like AES-256. Any data exchanges, like API calls to the backend, need to happen through secure transfer protocols like HTTPS.

Implement Secure Authentication Practices

Compromised accounts are a user’s worst-case scenario. Not only do victims lose access, but all the sensitive information tied to their accounts is suddenly out in the open too. Worse yet, users play no small part by neglecting credential security, most notably by using duplicate and weak passwords.

You can’t force users to change habits or adopt secure solutions like password managers. However, you can outfit your app with advanced security features that make unsafe user behavior moot.

Specifically, if you require accounts with usernames and passwords, you should also require multi-factor authentication. It can take the form of one-time verification codes or, better yet, grant access based on user biometrics. This prevents passwords from being the only means of access.

Alternatively, consider joining the growing number of app developers embracing passkeys as the safer and more straightforward password alternative. A single passkey contains a public-private key pair, with the latter stored on the user’s device. Account verification happens automatically, leaving users with no passwords to remember or expose.

Additionally, passkeys are only useful for accessing the app or service that issues them from the connected device. That makes phishing attacks targeting inexperienced users ineffective.

Regularly Develop App Updates

Keeping all the apps, operating systems, and devices you use in development is a core cybersecurity best practice. By extension, you should provide the same support to protect your users. A healthy update schedule ensures you’re not just rolling out new features and retaining user attention but also tackling the issues you’ve uncovered in the meantime.

Continuously Monitor and Test for Vulnerabilities

Any app potentially becomes a cyberattack target as soon as it’s available to the public. Hackers posing as legitimate users will try to exploit exploits, access confidential data, or reverse-engineer the app to crack it or give your competition an unfair advantage.

The only way to prevent this is through constant vigilance and improvement made possible by two practices – SIEM and penetration testing.

SIEM, or Security Information and Event Management, is a comprehensive system that monitors events, alerts, and logs to identify and combat vulnerabilities. It’s particularly adept at identifying abnormal user behavior that potentially points to signs of tampering. Monitoring is augmented with real-time alerts that help developers zero in on and fix exploits as they’re identified.

Penetration testing is an essential addition to SIEM efforts since it simulates real-world threats and helps identify previously undiscovered vulnerabilities in your apps. Security testing should also extend to email authentication mechanisms like DMARC and DKIM to ensure they are correctly configured to prevent email spoofing and phishing attacks, which remain a major threat to user security.

Prioritize User Data Protection

Thought-out data collection and protection policies have become a major consideration due to increased user awareness and the evolution of industry standards backed by laws like HIPAA or the GDPR.

By being transparent about data use and collection practices, you can uphold compliance standards and keep users safe. Users should have the option to monitor data collection, opt out of practices they disagree with, and remove all traces of their involvement with your app upon account deletion.

It’s best to keep data acquisition to a minimum since not doing so puts users at greater risk if a breach or leak makes sensitive information about them available to data brokers and other aggregators. Although individual users might eventually be able to get their digital footprint under control and learn how to stop getting spam emails because of a leak, the breach of their trust would be far harder to repair.

Conclusion

Secure app development hinges on a comprehensive and systematic application of best practices that prioritize users’ current and future safety. Integrating them from the beginning while continually striving to eliminate pain points like unsafe access and undiscovered vulnerabilities can be painstaking. Even so, it’s the only sustainable way forward in a threat landscape that relentlessly targets end users with increased frequency and sophistication.
