SWIFT CSP: Customer Security Programme Compliance Guide
Sections

Introduction to SWIFT CSP

The SWIFT Customer Security Programme (CSP) establishes mandatory security requirements for all organizations connected to the SWIFT network. Following high-profile attacks targeting SWIFT-connected institutions, CSP aims to raise the security bar across the global financial community.

Background

Origin:
Launched in 2017 following cyber attacks
Mandatory controls since 2018
Annual attestation required
Continuous evolution

Applicability

Who Must Comply:
Banks using SWIFT
Central banks
Market infrastructures
Corporate treasury operations
Investment managers
Payment processors

Framework Structure

Control Framework

Three Objectives:
1Secure Your Environment
2Know and Limit Access
3Detect and Respond
Eight Principles:
1Restrict internet access
2Protect critical systems
3Reduce attack surface
4Prevent credential compromise
5Manage identities
6Detect anomalies
7Plan for incident response
8Share information

Control Types

Mandatory Controls:
Must be implemented
Attestation required
Non-compliance visible
Enforcement actions
Advisory Controls:
Recommended best practices
Future mandatory candidates
Industry leading practices

Architecture Types

Architecture A

Description:
SWIFT interface on customer premises
Full local infrastructure
Most stringent requirements
Components:
SWIFT messaging interface
Local database
Communication interface
Operator PCs

Architecture B

Description:
Uses service bureau for SWIFT
Shared infrastructure
Reduced local footprint
Requirements:
Secure connection to bureau
Local security controls
Bureau due diligence

Architecture A3

Description:
Connector-based architecture
Alliance Lite2 users
Cloud-based options

Mandatory Controls

Anomaly alerting

Attestation Process

Annual Attestation

Requirements:
Self-assessment against controls
Evidence documentation
Management attestation
Submission to SWIFT
Timeline:
Calendar year assessment
Deadline: End of year
Validity: One year

Attestation Types

Self-Attestation:
Internal assessment
Management sign-off
Standard approach
Independent Assessment:
External validation
Third-party review
Enhanced assurance

Non-Compliance

Consequences:
Visible to counterparties
SWIFT notifications
Potential restrictions
Reputational impact

Implementation Guide

Phase 1: Assessment (Weeks 1-4)

Activities:
Architecture determination
Control gap analysis
Risk assessment
Remediation planning

Phase 2: Remediation (Weeks 5-16)

Activities:
Network segmentation
Security controls
Process implementation
Documentation

Phase 3: Validation (Weeks 17-20)

Activities:
Control testing
Evidence collection
Gap closure
Management review

Phase 4: Attestation (Weeks 21-24)

Activities:
Self-assessment completion
Evidence organization
Attestation submission
Counterparty communication

Common Challenges

Challenge 1: Network Segmentation

Solution: Dedicated SWIFT zone, jump servers, traffic control

Challenge 2: Legacy Systems

Solution: Compensating controls, upgrade planning, risk acceptance

Challenge 3: Third-Party Dependencies

Solution: Due diligence, contractual requirements, monitoring

Challenge 4: Resource Constraints

Solution: Prioritization, managed services, phased approach

Integration with Other Frameworks

Banking Regulations

SAMA CSF (Saudi Arabia)
CBUAE requirements
CBB framework

International Standards

ISO 27001 alignment
NIST CSF mapping
PCI DSS overlap

Future Evolution

Upcoming Changes

New mandatory controls
Enhanced requirements
Independent assessment expansion
Technology updates

Conclusion

SWIFT CSP compliance is mandatory for all SWIFT-connected institutions. Focus on network segmentation, strong authentication, and comprehensive monitoring to achieve compliance and protect against sophisticated financial cyber attacks.
