  • Exogenous virtual machine synchronization and replication
    Patent number: 10114834
    Abstract: The system and method described herein may provide a virtualized replication and high availability environment. In particular, a virtualized production server may run one or more virtual machines in one or more child partitions and have a replication and high availability engine installed in a parent partition. The replication and high availability engine may automatically discover the virtual machines running in the child partitions and automatically synchronize all files associated with the virtual machines to a virtualized replica server.
    Type: Grant
    Filed: December 12, 2016
    Date of Patent: October 30, 2018
    Assignee: CA, Inc.
    Inventors: Jinxing Yin, Pengcheng Dun

  • Remote procedure call (RPC) services fuzz attacking tool
    Patent number: 8819831
    Abstract: A system and method for testing a computer program using a computer system includes a plurality of computer systems communicating using a network. An interface parser module defines at least one program interface in a program file of a specified program. A fuzzer module reads the program file and identifies the program interfaces. An attack data generator module attacks the program interfaces and communicates with the fuzzer, and the fuzzer determines vulnerabilities in the specified program. A recorder records the attacking procedure. A verifier verifies remedies for vulnerabilities by replaying the attacking procedure of the program interface and determining vulnerabilities. A service status detective module restarts the specified program when the specified program ceases to operate or crashes.
