  7. 7SANStorage Area Network
    A high-speed subnetwork of shared storage devices.
    A SAN's architecture works in a way that makes all storage devices available to all servers on a LAN or WAN.
    .
  8. 8Management ProxiesRemote software that provides information on the target system and provides suggestions.
  9. 9SNMPSimple Network Management Protocol
    Are protocols for managing complex networks.

  16. 16MTAMessage transfer agent is software that transfers email from one computer to another using a client-server application.
  17. 17MUA SoftwareMail User Agent is a computer program used to access and manage a user's email.
    ex. Outlook
  18. 18MTA SoftwareMail Transfer Agent
    Exchange Server
  19. 19NASNetwork-attached storage
    Is a storage device connected to a network providing data access to a group of clients.
    SMB and NFS supported.
  20. 20Firewall TechniquesA) Packet Filter
    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
  30. 30EMIElectromagnetic Interference
    Equipment that interferes with normal operation of computer systems.
  31. 31SMB is the same as?CIFS
  32. 32What is SMB?A Linux protocol used by Microsoft OS allowing shared access to files and printers.
  33. 33What is Samba?Sofware on Linux that provides File/Print services for smb/CIFS clients.
    Allows Unix servers to communicate with the same networking protocol as Microsoft Windows products
  34. 34RFIRadio Frequency Interference
  35. 35SOAPMessaging protocol
    Allows software to run on different OS systems to communicate with each other.
  36. 36DASDirect Attached Storage
    Storage unit directly connected to a device.
  37. 37SCSISmall Computer System Interface
    Standards for physically connecting and transferring data between devices.
    Example Raid systems
    Parallel interface
  38. 38Fiber ChannelFiber or Copper
    technology for transmitting data between computer devices at data rates of up to 4 + Gbps.
  39. 39ISCSIInternet Small Computer Systems Interface
    SCSI over the IP network
  40. 40PostscriptDeveloped for desktop publishing
    More MAC end design
    Made for graphics
    Supported by most printers
  41. 41PCLPrinter Command Language
    Not originally designed for graphics.
    Supports different program languages for printers.
    Supported by most printers.
  42. 42Win PrinterNo intelligence on the printer.
    Documents are sent to printers from a device.
  43. 43CUPSPrint server software for LInux
  44. 44Raster GraphicsIndividual dots that create an image
    Graphics produce images as grids of individually defined pixels
  45. 45Vector GraphicsComplete image printing
    Produces images using points, lines, and shapes.
    Faster than Raster
  46. 46BINDAllows DNS to run on Linux
    Sofware developed by Burkly
  47. 47Purpose Proxy ServerFilter requests - deny/permit websites
    Cache information to speed up same requests in the future.
  48. 48DMZDemilitarized Zone
    a physical or logical subnetwork that exposes an organization's external-facing services to an untrusted network. An external network can access only what is exposed in the DMZ, while the rest of the organization's network is firewalled.
  49. 49GatewaysJoining of different systems together to communicate that may use different protocols.
  50. 50ExtranetA controlled private network that allows access to partners, vendors, and suppliers or an authorized set of customers.
    Ex. Remote VPN
  51. 51XMLIs a markup language that defines a set of rules for encoding documents in a format that is both human-readable and machine-readable
  52. 52Network Management ElementsSecurity: Ensuring that the network is protected from unauthorized users.
    Performance: Eliminating bottlenecks in the network.
    Reliability: Making sure the network is available to users and responding to hardware and software malfunctions.
  53. 53Difference between Manager and AgentManager polls agents for information.
    Any alerts are then referred to Managers.
  54. 54MIBManagement Information Database
    Are objects that can manage simple network protocols on the agent.
  55. 55Why would you do a network audit?Done to ensure that a network is performing correctly.
    Compares results to the initial audit at setup as a baseline.
