Abstract: There is disclosed in one example a gateway apparatus to operate on an intranet, including: a hardware platform; and an access proxy engine to operate on the hardware platform and configured to: intercept an incoming packet; determine that the incoming packet is an access request directed to an access interface of a resource of the intranet; present an access checkpoint interface; receive an authentication input response; validate the authentication input response; and provide a redirection to the access interface of the device.

Abstract: An apparatus, related devices and methods, having memory; and a processor operable to execute instructions stored in the memory configured to cache a first data object and a second data object received from a source in a cache group based on metadata received from the source, where the metadata identifies the first and second data objects as related and the first data object as a trigger object; receive a request from a client for the first data object; identify, based on a determination that the first data object is invalid and is the trigger object, the first data object and the second data object as invalid; request a valid first data object and a valid second data object from the source; and cache the valid first and second data objects, received from the source, in the cache group.

Abstract: Particular embodiments described herein provide for a system that can be configured to facilitate the use of a blockchain for distributed denial of service attack mitigation, the system can include a network security provider and a validating node. The network security provider can recognize that a distributed denial of service (DDoS) attack is occurring, create a block that includes data related to the DDoS attack, and publish the block that includes the data related to the DDoS attack for addition to a blockchain. The validating node can validate the block that includes the data related to the DDoS attack and the block that includes the data related to the DDoS attack can be added to the blockchain. The block that includes the data related to the DDoS attack can be analyzed to determine how to mitigate a similar DDoS attack.
