    B) Application Gateway
    C) Stateful Inspection
  21. 21IP SpoofingModification of packet headers
    Thinks it comes from a trusted source.
  22. 22Difference Unicode and ASCIIASCII has 7 text-based bits.
    The 8th bit is used for image lines.
    Unicode is 16 bits for high-quality graphics and styled font text.
  23. 23BaselineState of the software when it was first installed for comparison to future states.
  24. 24Audit TypesInventory Audits
    Facility Audit
    Operational Audit
    Efficiency Audit
    Security Audit
  25. 25Inventory AuditInventory Audits should be done before the network is operational
    Best performed when all the equipment is in one place
  26. 26Facility AuditFacility audit tracks network devices and notes physical location of all network equipment
    It is best to have network diagram.
    The diagram should be updated
  27. 27Operational AuditThis audit looks at daily operational parameters of the network:
    Network utilization
    Average # of collisions
    # of network errors
    Amount of broadcast traffic
  28. 28Efficiency AuditEvaluate performance of network-support staff and network users.
    Evaluated for their ability to respond to and troubleshoot network problems.
    Determine if there is sufficient # of adequately trained support personnel.
  29. 29Security AuditAll that requires limited access to passwords or locks.
    What virus protection is needed
    Which files should be backed up
    What type of emergency and disaster-recovery procedures should be implemented
