How are cybersecurity domains applied in the finance sector?

TL;DR: Financial institutions apply cybersecurity domains to protect digital assets, comply with regulations, and maintain customer trust—using frameworks like NIST, ISO 27001, and regional mandates like APRA CPS 234 and DORA.

The 6clicks expert guide Mastering the Cybersecurity Domain in 2025 highlights how the financial services industry faces some of the highest cybersecurity risks due to its central role in the global economy, high-value data, and interconnected digital infrastructure.

Banks, insurers, fintech firms, and capital markets players use the 8 cybersecurity domains as a blueprint to manage operational risk, secure customer data, and demonstrate compliance with regulators and auditors worldwide.

Domain application in finance:

• Security and risk management
  Central to enterprise-wide risk modeling, board-level governance, and compliance with APRA, PCI DSS, and Basel standards.

• Asset security
  Protects high-value customer data and payment processing systems using encryption, tokenization, and DLP.

• IAM & access control
  Enforces strong authentication (e.g., MFA, biometrics) for workforce and customer access.

• Security operations
  Deployed via 24/7 SOCs, SIEM/SOAR platforms, and incident response teams to meet regulatory SLAs.

• Security assessment & testing
  Frequent red teaming and vulnerability scans mandated by regulators like MAS, FFIEC, and EBA.

• Software development security
  Applies DevSecOps to digital banking apps and core platforms, with SBOMs and secure SDLC practices.

Why domains are critical in finance

With global regulations like:

• APRA CPS 234 (Australia)

• Digital Operational Resilience Act (DORA – EU)

• NIST and GLBA (USA)

...financial firms are under pressure to demonstrate not just security controls—but resilience, reporting, and recoverability.

Cybersecurity domains help financial entities:

• Maintain continuity and availability of core systems

• Avoid fines, data breaches, and loss of market confidence

• Align with evolving regulatory expectations across regions
