{#r_WS-SecurityErrorMessages__table_qkd_cfb_fr__entry__2}

| Error | Description |
|-|-|
| Invalid Security Policy Selected. Select an Inbound policy for Inbound Requests. | The default policy name is set to an outbound policy. [Set the default policy name](https://servicenow-prod.fluidtopics.net/aOX~jrjQ5t9nZQY1KHHmFA "Set the SOAP default security policy.") to an inbound security policy. |
| SOAP request not Signed. Policy requires signing. | The [SOAP security policy](https://servicenow-prod.fluidtopics.net/sTBQth13zJB9qSZPTI08ng#c_SOAPWebService__SOAP-default-sec-policy) requires signing and the inbound SOAP request is not signed. Either specify a different SOAP security policy or provide the SOAP request with a proper signature. |
| No profiles to authenticate. | The selected Security policy either does not have any security profiles (X509 or UserNameToken) or the security profiles are inactive. Verify at least one security profile is active. |
| Unable to verify signed request. | The inbound SOAP request contains an invalid signature. The SOAP request changed after being signed. |
| Failed to extract principal(s) from request. | The SOAP request has either been tampered or was not well formed. ServiceNow cannot extract credentials to authenticate the request. |
| Failed to authenticate WS-security, unknown type. | The SOAP request contains an unsupported security profile. Resend the request with a supported [security profile type](https://servicenow-prod.fluidtopics.net/sTBQth13zJB9qSZPTI08ng#c_SOAPWebService__WS-Security-profiles): X509 or UsernameToken. |
| Failed to authenticate WS-security. | ServiceNow failed to authenticate against the provided profile credentials. Verify that the SOAP request is using the proper credentials. |
