  • Patent number: 9633202
    Abstract: A method, system, and/or computer program product manages a distributed denial of service attack in a multiprocessor environment. A determination is made of (a) a first upper threshold for a normal number of packets from the multiprocessor environment to multiple destination addresses, (b) a second upper threshold for a normal ratio of the packets from the multiprocessor environment to a single destination address compared to the packets from the multiprocessor environment to the multiple destination addresses, and (c) a third upper threshold for a normal ratio of packets from the multiprocessor environment to a single port at a single destination address compared to packets from the multiprocessor environment to the multiple destination addresses. In response to the first and second thresholds being exceeded, a specific port is monitored to determine if the third upper threshold is being exceeded at that port, thus indicating an apparent distributed denial of service attack.

  • Patent number: 8646062
    Abstract: Embodiments of the invention provide for authenticating users of web-based applications by presenting a previously acquired signed digital signature. Examples establish secure user sessions between a client and a user in response to a verification of an identification of the user by the client, the client creating a unique username for the user and unlocking access by the user to a client digital signature for use with a request for service from a third party web server. A secure facilitator session is established between the client and a third party web server, wherein messages exchanged with the unique username and a unique session identification indicia of the secure facilitator session signed by the unlocked digital signature result in executed processes requested by the service identifier data if the messages are validated without the client requiring the user to verify user identification for any message until a secure facilitator session ends.
