BLOCKLIST

Blocklist for partners. See Enterprise Integration Patterns.

Definition

Blocklist — explicit list of partners, senders or identifiers whose messages are rejected before any processing. Negative counterpart to the allowlist.

Origin

Standard practice in application security; documented by OWASP and API Gateway patterns. In EDI, a blocklist is materialised in the AS2 configuration via AS2-From and in the SFTP configuration via the certificate CN.

Use

When a partner is terminated, their AS2-From is placed on the blocklist for 90 days to prevent any unauthorised resumption; the event is logged in the audit trail as proof.
