    Jimmy, an attacker, knows that he can take advantage of poorly designed input validiation routines to create or alter SQL commands to gain access to private data or execute commands in the database.  What technique does jimmy use to compromise a database?
    • A. 

      Jimmy can submit user input that executes an operating system command to compromise a target system

    • B.

    This IDS defeating technique works by splitting a datagram (or packet) into multiple fragments and the IDS will not spot the true nature of the fully assembled datagram.  The datagram is not reassembled until is reaches its final destination.  It would be a processor-intensive task for the IDS to reassemble fragments itself, and on a busy system the packet will slip through the IDS onto the network.  What is this technique called?
    • A. 

      IP Routing or Packet Dropping

    • B. 

      IDS Spoofing or Session Assembly

    • C. 

      IP Fragmentation or session splicing

    • D. 

      IP Slicing or Packet Reassembly
