Why is Fintech app security important??

 FinTech app security

Cybersecurity in FinTech is key to protecting personal and financial data. Many businesses offer mobile banking, electronic payments systems, and crypto trading with security risks. As the FinTech sector expands, financial service providers are prime targets for criminals. If a FinTech app fails to protect customer data, it may lead to severe consequences such as:

Financial losses to customers

Identity theft

Misuse of customer data to perform phishing and other cyber crimes

Loss of trust as a brand

Legal implications as per compliances such as GDPR and PCI DSS

Increased risk of phishing and other subsequent attacks

According to Global FinTech Market 2021, the sector is estimated to grow at a CAGR of 26.87%, reaching $31.5bn by 2026. As the FinTech market grows and attracts more hackers and intruders, common challenges of FinTech apps have emerged that are proving to be a roadblock to secure innovation.

Key challenges of FinTech app security

Challenges of FinTech app security

Identity management:

Seamless sharing of data is an essential attribute of FinTech. Since financial organizations gather loads of sensitive data, it creates concerns like data ownership and digital identity management. FinTech businesses must adhere to all necessary compliances to collect, manage, and store critical customer data to ensure maximum protection for customers’ data.

Data Security:

Hackers can exploit system weaknesses of FinTech apps and access critical data such as credit information, contacts, personal data, etc., and use it for financial fraud and data theft. Data security in FinTech should be of the top concern since it has been identified as the top concern for 70% of banks consulted during the Sixth Annual Bank Survey.

Regional FinTech security protocols:

FinTech applications should adhere to KYC (Know Your Customer) protocols as well as regional data protection regulations. For example, businesses that offer financial services in the European Union and the European Economic Area must abide by GDPR (General Data Protection Regulation). Non-adherence to these regulations can result in cyberattacks and huge fines from local governing bodies for non-compliance and exposing the data of users to non-reliable sources.

Common FinTech data protection regulations

fintech app security data protection process

Based on the FinTech company’s location and target markets, specific data protection regulations and compliance must be adhered to in the financial services industry. Some of the critical data protection regulations are as under:

General Data Protection Regulations (GDPR):

GDPR is essential compliance for businesses that offer financial services in the European Union and the European Economic Area. FinTech apps should comply with GDPR to ensure secure data storage for EU residents.

Payment Card Industry Data Security Standard (PCI DSS):

Data protection and compliance for businesses that manage credit card information. FinTech businesses should ensure their app is compliant with PCI DSS as it will optimize the security of credit, debit, and cash transactions and protect app users against any misuse of personal information.

Second Payment Services Directive (PSD2):

Regulation for electronic payments and cross-border transactions in Europe. FinTech apps compliant with PSD2 regulations can benefit from the security against cyber threats for processing electronic payments and safeguarding consumers’ financial data.

Regulation on Electronic Identification and Trust Services (eIDAS):

Provides a legal platform for transitions between FinTech organizations, businesses, government bodies, and citizens in the EU. eIDAS-compliant Fintech apps provide a consistent and legal framework for accepting electronic identities and signatures.

Financial Conduct Authority (FCA):

Data protection regulations for FinTech firms providing services in the United Kingdom. Since FCA is a renowned compliance body, FinTech app companies should consider FCA compliance to increase customer confidence and trust.

Act on the Protection of Personal Information (APPI):

Essential regulation for FinTech businesses managing data of Japanese residents. Apps compliant with APPI mean that the apps have enabled necessary cybersecurity measures that will secure the personal information of the app users.

Personal Information Protection Act (PIPA):

Essential regulation for FinTech businesses managing data of South Korean residents. PIPA compliance requires the data controllers and collectors to integrate technical, administrative, and physical measures for securing customers’ data against loss, theft, alteration, or damage.

Along with being compliant with the respective data protection regulations, FinTech applications should adhere to the latest best practices to ensure cybersecurity.

How to ensure FinTech apps security in 2024

Security must be the top priority for every FinTech company. They must safeguard their customers’ data. Here are the essential steps for making a secure FinTech app.

Implement multi-factor authentication:

Considering the sophistication and ability of cyber attackers, FinTech businesses cannot solely rely on passwords to protect their customers. When building a FinTech app, it is advised to implement multi-factor authentication where users prove their identity by making two or more claims.

Use code obfuscation:

Cybercriminals can clone a FinTech app in order to collect personal user data disguise. FinTech businesses should consider code obfuscation to prevent app cloning. Code obfuscation includes encrypting the code, removing revealing metadata, naming classes and variables with meaningless labels, or adding unused or meaningless code to an application binary.

Data encryption:

Encryption is the scrambling of data in order to hide critical information from unauthorized users. Cryptographic tools such as cryptographic hash functions may be leveraged to convert plaintext to ciphertext. Businesses should use encryption when releasing a FinTech app to protect critical customer data at rest or in transition.

Secure APIs:

Creating, testing, and integrating APIs is a part of building FinTech apps. Organizations design, develop, and consume APIs as part of building a FinTech app. Cyber-attackers often target APIs to breach the system and steal critical finance data. FinTech businesses can secure their app APIs by implementing the following methods:

Implement the OAuth 2.0 standard

Use authentication tokens

Encrypt your data and use digital signatures

Proactively identify and address API vulnerabilities

Use quotas, throttling, and API gateways

AI and Machine Learning:

AI-driven security solutions can learn from past incidents to predict and prevent future security threats. They can detect abnormal behaviours and potential fraud in real-time.

Blockchain Technology:

With its decentralized nature and cryptographic security, blockchain can offer enhanced security for transactions and data storage.

Security Information and Event Management (SIEM):

SIEM systems provide real-time analysis of security alerts and help organizations to track and respond to incidents.

Cloud Security Tools:

With many FinTech apps leveraging cloud technologies, cloud security tools help protect data stored off-premises and ensure secure data transmission.

Perform Penetration Testing

Penetration testing refers to performing false intrusive attacks on the app to identify any threats or vulnerabilities before the actual hackers do. Penetration testing reveals security vulnerabilities so that necessary enhancements can be made to improve overall app security.
