By requiring signed requests, you ensure that the authentication requests are coming from a trused source. This helps prevent unauthorized access and reduces the risk of man-in-the-middle attacks1.
Signed requests guarantee that the data within the authentication request has not been tampered with during transmission. This ensures the integrity of the authentication process1.
Many regulatory frameworks and security standards require the use of signed authentication requests to ensure secure data exchange. Enforcing signed requests helps organizations meet these compliance requirements1.
It helps establish a higher level of trust between the identity provider (IdP) and the service provider (SP), as both parties can verify the authenticity of the requests2.
Signed requests often include timestamps and unique identifiers, which help in mitigating replay attacks where an attacker might try to reuse a previously valid authentication request2.
