Understanding SWIFT CSP

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

Attestation Visibility

Non-compliance with SWIFT CSP is visible to your counterparties. Banks and financial institutions can see your attestation status, potentially affecting correspondent banking relationships and business opportunities.

Three CSP Objectives

Phase 1

Secure Environment

Protect SWIFT infrastructure from compromise

Phase 2

Know & Limit Access

Manage identities and restrict privileges

Phase 3

Detect & Respond

Identify anomalies and respond to incidents

Architecture Types

Architecture A

  • On-premises SWIFT interface
  • Full local infrastructure
  • Most stringent requirements
  • Complete control

Architecture B

  • Service bureau connection
  • Shared infrastructure
  • Reduced local footprint
  • Bureau due diligence

Architecture A3

  • Connector-based
  • Alliance Lite2 users
  • Cloud-based options
  • Simplified deployment

Key Mandatory Controls

Environment Security

SWIFT infrastructure segmentation
No direct internet access
Protected zone architecture
Security updates and patches
System hardening

Access & Detection

MFA on all SWIFT access
Strong password policy
Token management
Personnel vetting
Malware protection
Security logging

Network Segmentation Critical

The most challenging control for many institutions is Control 1.1: SWIFT Infrastructure Segmentation. This requires a dedicated secure zone with no direct internet access and strict traffic controls.
