PCI DSS
PCI DSS (Payment Card Industry Data Security Standard) is a compliance framework that requires organizations handling credit cards to implement security controls. It mandates authentication, encryption, access control, and regular security testing.
# WHAT TEAMS RUN INTO
- —
PCI DSS compliance is expensive and ongoing. Achieving compliance requires significant investment in controls, and maintaining compliance requires continuous testing and remediation.
- —
PCI compliance does not prevent breaches. Organizations that are PCI-compliant have still suffered breaches. Compliance is a baseline of good practices, not a guarantee of security.
- —
Compliance scope boundaries are unclear. An organization might be PCI-compliant for their payment systems but have weak security in adjacent systems, creating bridges for attackers to move from weak systems to payment systems.
# WHY IT MATTERS
PCI DSS forces organizations that handle payment cards to implement identity and access control seriously. The standard requires MFA for administrative access, strong authentication, and detailed audit logs. Organizations that meet PCI DSS standards have fundamentally better identity security than organizations that ignore it. The mandate makes compliance — and security — a business requirement.
