Abstract: A URL velocity monitor is integrated with a message-hold decision maker of an electronic mail processing system that processes electronic messages for a protected computer network. The URL velocity monitor receives or obtains a URL, decomposes the URL into URL features based on logical boundaries, and determines features of interest from the URL features for velocity tracking. Examples of URL features can include a randomized URL segment. The velocity of each feature of interest is tracked over a period of time using a counting algorithm that employs a slow counter or a fast counter. The two different counters track two types of velocities which represent different domain behaviors targeting the protected computer network. The URL velocity monitor determines whether the velocity of a feature of interest is accelerating within the time period. If so, the URL is placed in a queue or a sandbox.

The confidence scores indicate need to re-authorize the tokens and/or disable them temporarily.

Abstract: Techniques are described herein that are capable of dynamically failing over authentication traffic to a backup authentication system by a proxy system. An authentication request, which requests authentication of a principal, is received at the proxy system. The authentication request is directed to a primary authentication system. A determination is made, by the proxy system, that the primary authentication system is incapable of providing a valid response to the authentication request. The backup authentication system is caused, by the proxy system, to authenticate the principal using an authentication package received from the primary authentication system by dynamically routing the authentication request to the backup authentication system as a result of the primary authentication system being incapable of providing a valid response to the authentication request.

Abstract: Security policies are made dependent on location of a device and the location of a device is determined and the appropriate security policy applied without providing the device's location to a server. A device determine its location and identifies a security policy identifier mapped to a zone including the location. The device requests the security policy corresponding to the identifier from a server and implements it. The device may also store a database of the security policies and implement them according to its location. Devices registered for a user evaluate whether locations detected for the devices correspond to impossible travel by the user. Objects encoding geolocation data of a device may be encrypted with a private key of the device and the public key of another to prevent access by an intermediary server.
