  • Publication number: 20170046211
    Abstract: An insider attack resistant system for providing cloud services integrity checking is disclosed. In particular, the system utilizes an automated integrity checking script and virtual machines to check the integrity of a service. The system may utilize the integrity checking script and virtual machines to execute a set of operations associated with the service so as to check the integrity of the service. When executing the set of operations, the system may only have access to the minimum level of access to peripherals that is required for each operation in the set of operations to be executed. After each operation is executed, the system may log each result for each operation, and analyze each result to determine if a failure exists for any of the operations. If a failure exists, the system may determine that a change in an expected system behavior associated with the service has occurred.

  • Publication number: 20170034220
    Abstract: A system and method for identifying distributed attacks, such as, but not limited to, distributed denial of service attacks and botnet attacks, in a first network serviced by a first carrier and configured to alert a second network serviced by a second carrier that is different from the first carrier is disclosed. Once an attack has been identified, an attack alert is generated and provided to the second network or other aspects of the first network, or both. The attack alerts may be distributed dynamically with the second network via diameter based security protocol Rs. Such system and method may mitigate distributed malicious attacks by sharing destination internet protocol and bad international mobile subscriber identity information across carriers.

  • Patent number: 8695095
    Abstract: Mitigation of malicious software in wireless networks and/or on mobile devices is provided. A mobile malicious software mitigation component is provided that obtains an internet protocol address that is exhibiting malicious software behavior, a profile of the malicious software behavior, and a time of the malicious software behavior. The malicious software mitigation component can determine an identity of a mobile device that was assigned the internet protocol address during the time it was exhibiting malicious software behavior, and transmit the profile to the mobile device. In addition, the malicious software mitigation component determine if the duration of the assignment of the internet protocol address to the mobile device is sufficient for positive identification.
