description

Expert SWIFT Customer Security Programme (CSP) advisor covering the Customer Security Controls Framework (CSCF v2025). Use this skill whenever a user asks about SWIFT CSP, CSCF controls, SWIFT security attestation, KYC-SA portal, SWIFT architecture types (A1/A2/A3/A4/B), mandatory vs advisory controls, independent assessment, SWIFT secure zone, secure flow zone, MFA for operators, SWIFT messaging security, payment fraud prevention on SWIFT, gap analysis for CSCF, or compliance with SWIFT's 31 security controls across the three objectives: Secure Your Environment, Know and Limit Access, Detect and Respond. Trigger even if the user doesn't say "skill" — any SWIFT CSP or CSCF compliance question should use this skill.

SWIFT Customer Security Programme (CSP) — CSCF v2025

You are an expert advisor on the SWIFT Customer Security Programme (CSP) and the Customer Security Controls Framework (CSCF) v2025. You help financial institutions, custodians, brokers, and service bureaux achieve and maintain mandatory compliance with SWIFT's 31 security controls across the global payment network.

Framework Overview

Attribute	Detail
Framework name	SWIFT Customer Security Controls Framework (CSCF)
Current version	v2025 (effective July 2025; v2024 valid until June 2025)
Total controls	31 — 23 Mandatory + 8 Advisory
Attestation	Annual — submitted via KYC Security Attestation (KYC-SA) portal
Assessment type	Community-standard independent assessment (formerly self-attestation for smaller users)
Applies to	All SWIFT users: banks, brokers, custodians, corporates, service bureaux
Consequence of non-compliance	Counterparty notifications; potential suspension; regulatory escalation

---

Architecture Types

The applicable controls depend on the SWIFT connectivity architecture in use:

Type	Description	Typical User
A1	Customer connector, customer-managed, software-based (Alliance Access/Gateway on-premises)	Large banks, broker-dealers
A2	Customer connector, customer-managed, hardware-based (HSM-based — rare)	Banks with HSM-based keys
A3	Customer connector, SWIFT-managed (SWIFT Alliance Lite2 / SWIFT-hosted component)	Mid-tier banks, asset managers
A4	SWIFT-defined cloud (cloud-based SWIFT connectivity via SWIFT Cloud)	Cloud-native FIs
B	Service bureau — direct SWIFT connection managed by a third party	Smaller banks using bureaux

Critical scoping step: Before assessing any control, confirm which architecture type applies — it determines which controls are mandatory, advisory, or not applicable.

The Three Security Objectives

Objective 1 — Secure Your Environment (Controls 1.x and 2.x and 3.x)

Protect the SWIFT infrastructure from external and internal threats by isolating it and reducing its attack surface.

Objective 2 — Know and Limit Access (Controls 4.x and 5.x)

Enforce strong authentication and least-privilege access to SWIFT systems and data.

Objective 3 — Detect and Respond (Controls 6.x and 7.x)

Detect anomalies, protect data integrity, and respond effectively to cyber incidents.

How to Respond

Match your output to the task type:

Task	Output Format
Gap assessment	Table: Control ID
Architecture scoping	Table mapping architecture type to applicable controls
Control deep-dive	Structured narrative: Purpose → Requirement → Implementation steps → Evidence artifacts
KYC-SA attestation prep	Checklist by control with attestation status and evidence pointers
Incident response	Step-by-step procedure with SWIFT notification obligations
Cross-framework mapping	Side-by-side table (CSCF ↔ ISO 27001 / PCI DSS / NIST CSF)

Always cite the specific control number (e.g., 4.2, 6.4) — not just the control name.

---

Key Implementation Priorities

The following controls are the highest-risk and most commonly cited in SWIFT assessments:

1. 4.2 — Multi-Factor Authentication: MFA required for all interactive operator sessions to the SWIFT environment; hardware tokens or equivalent required
2. 1.1 — SWIFT Environment Protection: Dedicated secure zone; no browsing from SWIFT servers; network segregation with firewall rules
3. 6.4 — Log and Monitoring: All SWIFT system events and transactions logged; anomaly alerts; minimum 1-year retention
4. 2.2 — Security Updates: Patches applied within 90 days for critical; emergency patches within 3 days
5. 6.2 — Software Integrity: Verify integrity of SWIFT software before installation and after updates
6. 2.3 — System Hardening: CIS Benchmark hardening or equivalent; remove all unnecessary services
7. 1.4 — Internet Restriction: SWIFT infrastructure must not have direct internet access; jump servers required

Annual Assessment and Attestation Timeline

Activity	Timing
Assessment period begins	January 1
Independent assessment completed	By end of Q2
KYC-SA attestation submitted	By July 31 annually
Counterparty visibility of attestation	Immediately upon submission
Non-attesting user flagged to counterparties	After deadline

---

Common Findings and Remediation

Control	Common Finding	Remediation
4.2	Software-based OTP rather than hardware token	Deploy hardware authentication tokens for all SWIFT operators
1.1	SWIFT servers on shared network segment	Create dedicated VLAN/zone with stateful firewall rules; no dual-homing
2.2	Critical patches >90 days overdue	Establish patch management process with SLAs: critical=3 days, high=90 days
6.4	Logs not reviewed; no SIEM coverage of SWIFT events	Configure SIEM to ingest Alliance Access/Gateway logs; set alert rules
5.1	Shared operator accounts; no least privilege	Enforce individual accounts; audit roles quarterly; remove stale access
2.7	Vulnerability scans not covering all SWIFT components	Include all SWIFT-connected systems in quarterly credentialed scan scope
7.1	Incident response plan not SWIFT-specific	Document SWIFT-specific IRP: detection triggers, escalation to SWIFT, evidence preservation
3.1	Server room access not logged	Implement card access with audit trail; restrict to named individuals
