Documentation

Definition

A Web Service consumer calls a service on a provider system. Such messages may be intercepted and replayed, to re-execute the same operation.

WS-Security offers two counter measures to prevent message replays.

Timestamps

Messages protected by WS Security contain timestamps. When configured for WS-Security, providers reject messages outside the timeframe specified by the timestamps and clock skew.

Signatures

SOAP messages containing an WS Security header with XML Signatures can be used to check for replays. When replay detection is enabled, the system will store all signature values for 60 minutes and reject messages with an identical signature value. As messages differ by elements like timestamps, message id, the same signature value is not expected.
