The modern finance industry has to process vast amounts of different data. Fintech applications, including mobile banking, payment gateways, investment platforms, and more, handle sensitive transactions, making them lucrative targets for hackers and cybercriminals. Therefore, fintech developers and organizations must adopt robust security practices to safeguard user information, protect their clients from financial fraud, and maintain trust.

Whether you are a developer, a security professional, or an organization in the financial industry, this article will provide valuable insights and practical recommendations to enhance the security of your fintech applications.

This article is a comprehensive guide to security best practices for fintech application development. If your development team implements these practices, you will be able to detect potential vulnerabilities and mitigate risks associated with hacking, data breaches, and unauthorized access. 

Let’s dive in!

Best practices for secure fintech application development

With the increased sophistication of cyber threats, the importance of incorporating security measures cannot be overstated. The consequences of a security breach in a fintech application can be severe, resulting in financial losses, reputational damage, and legal implications. 

So, what are the key application security strategies when it comes to fintech application development? Let’s take a look together.

Find a tech vendor with established cybersecurity policies

Selecting the right tech partner is no easy task, but we assure you that it pays off. Here are some steps that will help you find one:

Step 1. Research and evaluate various tech vendors and their offerings. Look for vendors that provide solutions in your industry or the ones that you need. It is also a good idea to pay attention to customer reviews. 

Step 2. Visit the vendor’s website and examine their commitment to cybersecurity. Look for dedicated sections or pages discussing their security practices, policies, and certifications. Check if they have a dedicated security team or Chief Information Security Officer.

Step 3. Check if the vendor complies with industry standards and regulations relevant to your requirements. Some common certifications to look for include ISO 27001, SOC 2, and PCI DSS.

There is way more to it than just these three steps, but they will help you to start searching and longlisting your potential partners. 

Hire a team that uses secure coding practices 

When going for fintech application development, it is crucial to follow secure coding guidelines and frameworks. For instance, to mitigate common security vulnerabilities, it is advisable to check the code against OWASP Top 10. We will not go into too many tech details here, leave it for your team that brings fintech app security solutions to life. Generally, validating and sanitizing user input helps prevent the processing of malicious data. Storing sensitive information, such as passwords, in plain text should be avoided at all costs, and strong encryption algorithms should be utilized for secure storage and transmission of sensitive data.

Ensure strong authentication and authorization

To enhance adherence to application security best practices, it is essential to enforce strong password policies, including requirements for minimum length, complexity, and expiration. Implementing multi-factor authentication (MFA) provides an additional layer of security by requiring users to provide multiple credentials or verification factors. Secure protocols such as HTTPS should be used for transmitting sensitive data and user credentials to protect against eavesdropping and data tampering. 

Use robust user and account management

Strong encryption algorithms are a must to safeguard sensitive user data. Additionally, implementing mechanisms to detect and prevent account enumeration, brute force attacks, and credential stuffing helps protect against unauthorized access attempts. Enabling account lockouts after a certain number of failed login attempts adds a layer of defense against automated attacks. By incorporating these measures, fintech applications can better protect user data and ensure a secure user experience.

Secure data storage and transmission

To ensure the security of a fintech application, it is essential to implement robust encryption practices to protect data both at rest and in transit. This involves using industry-standard encryption algorithms and employing proper key management practices to safeguard sensitive information effectively. Regularly backing up data and testing the restoration process is important to maintain data integrity and availability. Additionally, implementing secure protocols like TLS/SSL for data transmission helps prevent eavesdropping and tampering, ensuring the confidentiality and integrity of user data throughout its journey. 

Comply with industry standards and regulations

Fintech regulations differ depending on the country. However, there is an aspect that stays the same: complying with these regulations helps protect user data, maintain privacy, and ensure the secure handling of financial transactions. Additionally, it is important to regularly assess and update your application’s security controls to meet evolving compliance requirements. This includes staying informed about changes in regulations and industry best practices and implementing necessary changes to maintain compliance.

What security features must a fintech app have to prevent hacking?

To ensure the security of a finance application, several data protection best practices can be implemented during the development process. Fintech app security solutions include:

Biometric authentication 

Implementing biometric authentication is one of the key application security best practices, as it adds an extra layer of security by allowing users to access the app only with their unique biometric data, such as fingerprints or facial recognition.

Multi-factor authentication 

Utilize multi-factor authentication, which requires users to provide additional verification, such as a one-time password (OTP) generated through apps like Google Authenticator, along with their password when logging into the investment app.

Defense against cybersecurity threats 

Implement features that protect users from potential cyber-attacks. This includes automatic log-out from the app when the user session is over, regular installation of security patches, and ensuring that the app is only available on trusted marketplaces such as Google Play or the App Store.

Data encryption 

Utilize strong data encryption practices to safeguard sensitive user information, including cardholder details. Storing such information without encryption can expose users to potential financial losses if hackers gain unauthorized access.

Conclusion:

It is crucial to recognize that security is an ongoing process, and staying proactive is key. Regular security assessments, code reviews, and keeping up to date with emerging threats are essential for maintaining the security of fintech applications. Collaboration with security experts, adherence to industry regulations, and continuous monitoring of the evolving threat landscape will further enhance the security posture of fintech platforms.

By incorporating security best practices for fintech application development and adhering to applicable regulations, developers can ensure secure fintech application development that safeguards user data, mitigates risks, and provides a trusted platform.

Remember, security is not just a necessity but also a competitive advantage. By prioritizing the security of fintech applications, we can shape a future where digital finance thrives with trust, reliability, and peace of mind for all users.
