20140165194 | Attack Protection Against XML Encryption Vulnerability - Protection against an attack which exploits an eXtensible Markup Language (XML) Encryption vulnerability includes receiving a ciphertext request utilizing an EncryptedKey element and detecting either a failure to decrypt the cipher value in the EncryptedData element or a failure to parse the resulting decrypted XML. Upon detecting the failure, a count of failures associated with the EncryptedKey element is incremented, and when the count exceeds a threshold number of failures, subsequent usage of the EncryptedKey element and delivery of the request to an application service are prevented. Optionally, a rejection message is returned to the requester. | 06-12-2014 |
20140189123 | Dynamically selecting an identity provider for a single sign-on request - An identity provider (IdP) discovery service operative at a service provider (SP) is described. In operation, and as valid requests are received by the SP via normal IdP-initiated flows, the SP builds-up knowledge about the relationship between the IdP (that redirected the request) and the initiator of the request. The IdP instance typically is inferred from an HTTP referrer field, and information about the initiator may be ascertained from client-specific information, such as client system IP address, client DNS domain, a domain of a user e-mail address, a target URL for the incoming request, or the value associated with a particular HTTP header field. This knowledge is maintained in one or more mapping table(s) that associate request attributes-to-IdP instance data. The mappings are then used to facilitate IdP discovery for a new incoming request to the SP that has been determined to originate from other than an IdP. | 07-03-2014 |
