Open Banking: The Cyber Risks Involved

Open banking is a concept that refers to the sharing of financial information between different financial institutions or third-party providers through an open application programming interface (API). This enables customers to share their financial data securely and quickly with other financial institutions or third-party providers.

This form of banking is vulnerable to many forms of cyber threats that are worthy of being highlighted, including:

  • API Vulnerabilities: Open banking relies heavily on APIs to share data between different institutions. If these APIs are not adequately secured, cybercriminals can exploit them to gain unauthorized access to sensitive data. These attacks can be through API vulnerabilities, including SQL injection attacks, XML injection attacks, and cross-site scripting attacks.
  • Man-in-the-Middle Attacks: Man-in-the-middle (MITM) attacks occur when a cybercriminal intercepts communication between two parties and steals sensitive information. In open banking, MITM attacks can occur when a cybercriminal intercepts data being transmitted between a bank and a third-party provider. They can then use this information to gain unauthorized access to bank accounts or other sensitive data.
  • Credential Stuffing: Credential stuffing occurs when a cybercriminal uses stolen login credentials to access an account. In open banking, malicious actors can leverage credential stuffing to access a customer’s bank account or other sensitive financial data. This can occur if the third-party provider does not have strong enough security measures to protect customer login credentials.
  • Account Aggregation Risks: Account aggregation involves aggregating data from multiple bank accounts into a single platform. This can create a single point of failure for cybercriminals to target. If a cybercriminal gains access to the account aggregation platform, they can potentially gain access to all the aggregated accounts, which can be catastrophic.

Cybersecurity Best Practices for Fintech Companies

Fintech companies must take cybersecurity seriously to protect their systems and data from cyber risks. The following are some of the many cybersecurity measures that fintech companies must implement to combat cyber risks:

Multi-Factor Authentication:

Multi-factor authentication (MFA) adds an extra layer of security to user authentication by requiring the user to provide two or more authentication factors before granting access to a system (MFA is an important aspect for organizations implementing defense-in-depth). This could be a combination of something the user knows (such as a password), something they have (such as a physical key), or something they are (such as a fingerprint). MFA significantly reduces the risk of a cyberattack by adding an extra layer of security that is much harder for hackers to bypass.

Data Encryption:

Encryption converts data into a coded form that someone with the decryption key can only access. Fintech companies should use encryption to protect sensitive data in transit and at rest. Data in transit refers to data sent over the internet, while data at rest refers to data stored on servers. Encryption ensures data is scrambled and unreadable to unauthorized parties.

Cloud Security:

Ensures the platform built in the cloud is secured and hardened with security controls. Cloud security is a crucial aspect of fintech cybersecurity. It is essential for fintech companies to implement strong access controls and authentication measures, encrypt data both in transit and at rest, and regularly monitor and audit their cloud environment for any suspicious activity.

API Security:

API and open banking security are crucial aspects of the fintech industry. Open banking allows third-party providers to access customer financial data through APIs, increasing the risk of unauthorized access and data breaches. To ensure API and open banking security, strong authentication and authorization measures, such as access tokens and API keys, should be implemented. Regular monitoring and auditing of API activity can help identify and prevent any malicious activity. Open banking providers should also work with reputable third-party providers that have strong security protocols and compliance certifications. Usage of API security gateway will also significantly enhance API security posture.

AppSec (Application Security)

AppSec and source code management are essential components of fintech cybersecurity. AppSec involves identifying and addressing security vulnerabilities in applications, including web and mobile applications. To ensure AppSec, it’s crucial to implement secure coding practices, such as input validation and output encoding, to prevent attacks like SQL injection and cross-site scripting (XSS). Regular security testing, such as penetration testing and vulnerability scanning, can also help identify and remediate security vulnerabilities. Source code management involves implementing secure code development processes, such as version control and code reviews, to prevent errors and ensure that code changes are properly tested and deployed.

Tokenization:

Tokenization is the process of replacing sensitive data with a non-sensitive token, which can be used for processing transactions without exposing the original data. Fintech companies must employ tokenization to protect customer payment card data and other sensitive information.

Continuous Monitoring:

Threat detection and response are crucial for maintaining the security and reliability of financial systems. A dedicated CSOC function (outsourced or in-house), can help ensure effective threat detection and response by implementing security monitoring and alerting systems into a XDR data lake with logs from SIEM, EDR, FWs, WAFs, AD, MFA, PAM, etc and incident response procedures to mitigate the impact of security incidents.

Regular Security Audits:

Fintech companies should conduct regular security audits, vulnerability assessment and penetration testing to identify vulnerabilities and potential risk areas. This can be done in-house or by hiring an external security firm to conduct the audit. Security audits typically involve a comprehensive review of the company’s security policies, procedures, and technical controls.

Hiring a Reputable Cybersecurity Agency:

The fintech industry is fast-paced, with new forms of vulnerability sprouting out daily. The in-house cybersecurity team may not be equipped with the best techniques to prevent these ever-evolving threats. With the fragility of the data they handle, fintech companies must invest in their cybersecurity by hiring a reputable cybersecurity firm to help them with risk evaluation, management, and recovery technique to combat the evolving threats.
