  15. 15. What equipment is needed to build a Home Network? Sketch out your network, showing each computer and printer. Next to each computer, note the hardware, such as modems and network adapters, installed on each computer. Determine the type of network adapters, if any, you need for your network Make a list of hardware that you need to buy.
  16. 16. What equipment is needed to build a Home Network? If you have a dial up connection, you will already have the modem installed in your computer All recent computers will have Network Adapters already installed If you have broadband (Verizon or Comcast), you will already have a modem Also, Verizon provides the router and cables with their DSL or FIOS broadband connection

Computer security Make sure that you have all the latest Microsoft patches installed. Make sure that your Virus protection is installed and that it is regularly updated Install a good software firewall Check status with Windows Security Center Regularly run Spyware removal programs If you use Microsoft Office or any of its components, such as Word or Excel, make sure that you update that as well
  42. 42. Router security
  43. 43. Router security Therouter comes with a set up screen, which you access using 192.168.1.1 in the address bar of your browser, and then entering a password
  44. 44. Router security Thedefault passwords for routers are well known - mine was Admin. You need to change this to something that will prevent someone accessing your network from gaining access to the settings.
  45. 45. Router security
  46. 46. Router security You can only set up the Router through a computer that is connected to the Router by a wire. Once the Router is set, the computer can be unplugged and used wirelessly if necessary.
  47. 47. Wireless SecurityThe key requirement for wireless security is to stop others from accessing your network.Have a hardware firewall in addition to your software firewallEncrypt all data traffic between the wireless computer and the routerProtect that encryption with network names and passwordsPrevent the network broadcasting its name to the worldOnly authorize access to named computers
  48. 48. Wireless Security Your Router should include an SPI and NAT firewall. Make sure that it is turned on
  49. 49. Wireless Security Give a name for the network. This is the SSID. Disable SSID Broadcast
  50. 50. Wireless SecuritySet the Security Mode to WPA or better yet, WPA2.Set WPA Algorithms to TKIPSet the WPA Shared Key.
  51. 51. Wireless Security Finally, only authorize access to named computers  Set a MAC Filter for all computers using the wireless network.  Each computer has a unique identification number called the MAC Address.You only need to enter the MAC Addresses forcomputers accessing the network wirelessly.You do not need to include computers that are wired to the router.
  52. 52. Wireless Security Finding the MAC Address Goto Start, and then Run.
  53. 53. Wireless Security Finding the MAC Address Type CMD in the box and a window will open.
  54. 54. Wireless Security Finding the MAC Address At the flashing cursor, type ipconfig/all and hit Enter. You will see information including Physical Address in the form of 00-01-AX-B3-DY-71
  55. 55. Wireless SecurityFinding the MAC Address Physical Address
  56. 56. Wireless Security Finding the MAC AddressNow back to the Router
  57. 57. Wireless SecurityFinding the MAC Address
  58. 58. Wireless Security The final step in the process is to make sure that you set up identical settings on the laptop or wireless computer – the same Mode, – the same SSID and – the same shared key
  59. 59. Sharing printers and files Ifyou plan to access files or a printer between computers, you will need to allow Sharing for the Printer and the appropriate folders
  60. 60. Sharing printers and files Check “Share the printer” Give the shared printer a descriptive name
  61. 61. Sharing printers and files
  62. 62. Sharing printers and files Ifyou share folders, you will need to tell Zone Alarm that to allow the access. Open the Zone Alarm Control Center, and select Firewall on the left.
  63. 63. Sharing printers and files Select the Zone tab at the top. Click Add Select IP Range. Enter a range such as 192.168.1.100 to 192.168.1.103
