  • Patent number: 10270760
    Abstract: Services from domainless machines are made available in a security domain under a virtual name. Each machine is not joined to the domain but can reach a security domain controller. The controller controls at least one security domain using an authentication protocol, such as a modified Kerberos protocol. One obtains a set of security domain credentials, generates a cluster name secret, gives the cluster a virtual name, and authenticates the machines to the domain controller using these items. In some cases, authentication uses a ticket-based protocol which accepts the cluster name secret in place of a proof of valid security domain membership. In some, the domain controller uses a directory service which is compatible with an active directory service; the cluster virtual name is provisioned as an account in the directory service. The cluster virtual name may concurrently serve clients on different security domains of the directory service.

  • Patent number: 10158659
    Abstract: A phony profiles detector for an on-line social network system is described. The phony profiles detector uses characteristics of a profile that was associated with an indication that it represents a malicious user, a so-called seed profile, to identify other profiles that should be flagged as potentially the source of undesirable behavior. Based on the degree of similarity determined for a subject profile with respect to a seed profile, the phony profiles detector generates a malicious user indicator and stores it as associated with the subject profile.
