Fintech cybersecurity challenges

Now, let’s move on to the most interesting part. Implementing security measures in general is a challenging activity, but for fintech, it’s on another  level. The most common risks you can face regarding security are: 

Data breaches

A data breach can occur when an unauthorized person gains access to sensitive data, like financial information, and uses it for fraudulent purposes. The consequences of a data breach can be severe and long-lasting, including financial losses, loss of customer trust, and damage to reputation. You must implement strong security measures and train your employees to reduce the risk of data breaches occurring.

Insider threats

Insider threats are another significant cybersecurity challenge faced by fintech companies. An insider threat is a security risk that comes from within an organization, for example, an employee or contractor who has authorized access to sensitive data or systems. Insider threats can come in many forms, including intentional actions (stealing data or selling confidential information), or unintentional actions (clicking on a malicious link or falling for a phishing scam).

Compliance with regulations

Fintech companies must adhere to numerous regulations and standards to ensure the protection of their customers' financial information. Some of the key regulations and standards include the General Data Protection Regulation (GDPR), the Payment Card Industry Data Security Standard (PCI DSS), and the Federal Information Security Modernization Act (FISMA).

Non-compliance with these regulations can result in significant financial penalties, legal action, and damage to the company's reputation. Therefore, it’s essential for you to stay up-to-date with the latest regulations and standards, implement appropriate security controls, and regularly conduct security audits to ensure compliance.

Emerging technologies

Emerging technologies present both opportunities and challenges for fintech companies in terms of cybersecurity. There are aspects of these technologies that can definitely enhance the security of financial data. One prime example is blockchain. This technology provides a decentralized and immutable ledger that can improve the security and transparency of financial transactions.

However, emerging technologies like artificial intelligence (AI) and the Internet of Things (IoT) can also introduce new cybersecurity risks. For example, AI-powered attacks can exploit vulnerabilities in systems, and IoT devices can be used as entry points for cyberattacks. Therefore, fintech companies must implement appropriate security measures, like authentication and access controls, to mitigate the risks posed by these emerging technologies.

Third-party risk

Third-party vendors can provide valuable services and technologies to fintech companies, but they can also introduce new security risks. When fintech companies outsource a certain service to a third-party vendor, they must ensure that these vendors have appropriate security measures in place to protect sensitive financial data. This includes conducting thorough due diligence on third-party vendors, including background checks and security assessments, and ensuring that contracts include security requirements.

Cybersecurity: Best practices in fintech

We have named the most common cyber threats a fintech solution can face. Now we are going to discuss the most efficient preventive measures you can implement to protect your company’s data and minimize the possible damage a cyberattack can cause.

Conduct regular security audits

By conducting regular security audits, fintech companies can identify and address potential security risks before they can be exploited by cyber attackers. This can help prevent data breaches, protect sensitive financial data, and maintain the trust of customers and stakeholders.

Security audits should be conducted by experienced and qualified security professionals who have a deep understanding of the latest cybersecurity threats and best practices. They should also be conducted using a risk-based approach, focusing on the areas of the organization that are most critical to its operations and the protection of sensitive financial data.

Implement access controls

Implementing access controls involves identifying and classifying sensitive financial data, and determining which employees or third-party vendors require access to this data to perform their job functions. Access should be granted on a need-to-know basis and should be reviewed regularly to ensure that access is appropriate.

Encrypt data

Encrypting sensitive financial data helps protect against data breaches and unauthorized access by cyber attackers. In the event that a cyber attacker gains access to encrypted data, they would be unable to read or use the data without the decryption key.

Fintech companies should implement encryption for all sensitive financial data, both at rest and in transit. This includes customer data, transaction data, and any other data that is critical to the operations of the organization.

Use a layered security approach

Multiple layers of security controls will help fintech companies to provide increased protection against cyber attacks and meet regulatory requirements for cybersecurity. To implement a layered security approach, fintech companies should conduct a comprehensive risk assessment, develop a cybersecurity plan, and regularly test and evaluate their security controls.

Monitor systems and data

By implementing a SIEM system and DLP measures, fintech companies can detect and respond to cyber threats in real-time, minimizing the potential impact of a cyber-attack. Fintech companies should also establish clear data handling policies and procedures to ensure that employees are aware of their responsibilities for protecting sensitive financial data.

Educate employees

Employees are often the first line of defense against cyber threats, and their actions can have a significant impact on the overall cybersecurity posture of the organization.

To effectively educate employees, fintech companies should provide regular cybersecurity training and awareness programs. These programs should cover topics like password security, phishing awareness, and social engineering tactics.

Employees should also be trained on the organization's cybersecurity policies and procedures, including how to report security incidents and how to handle sensitive financial data.

Stay up-to-date on regulations

To stay up-to-date on regulations, fintech companies should establish a compliance program that includes ongoing monitoring of regulatory changes and updates. This can include subscribing to regulatory news alerts, attending industry conferences and webinars, and engaging with industry associations and regulatory bodies.
