Abstract: Disclosed are systems and methods to combine a reputation score for a software application publisher or vendor and code analysis techniques to provide a method of ranking software applications. A user downloading a software application may be confident that the software application is reliable and does not contain malicious content based on the ranking applied to the particular software application. Code analysis techniques allow for an application ranking even when there may not be enough historical information about the publisher/vendor to create a solid reputation score. A software application rank may be used internally to a software application store prior to making the software application available to the public.

Then, possible subscriber account misuse may be discovered by performing behavior-based anomaly detection, including a comparison of a subscriber profile associated with the subscriber account with recent subscriber account usage information, to identify one or more behavioral anomalies in outbound message flow originated from a subscriber account, the behavior-based anomaly detection.

Abstract: At least a portion of a transmission of an outgoing first email from a first email account to at least a second email account is encrypted. Second email address data is changed corresponding to the second email account to cause replies to the first email intended for the second email account to be sent to an intermediate device prior to being routed to the second email account. Replies to the first email are then sent to the intermediate device and sent over one or more encrypted channels. Replies to the first email including the changed email address data are decoded to identify the second email address data associated with the second email account. A reply to the first email is then sent to the second email account based on the identified second email address data.

User selection of a particular policy element via the interactive GUI causes a subset of the security policies to be identified, each security event in the subset based at least in part on a particular security policy represented by the particular policy element.

Abstract: A first computing device is detected as substantially collocated with a wireless token device, using a short-range wireless communication network and a connection is established between the first computing device and the token device over the short-range wireless network. Authentication data is sent to the first computing device from the token device over the short-range wireless network to authenticate the token device at the first computing device. Authentication of the token device permits data accessible through the first computing device to be made available to a holder of the token device and to be presented on a user interface of the first computing device. In some instances, the wireless token device may otherwise lack user interfaces for presenting the data itself.
