2 There is no reason for any individual to have a computer in his home. Ken Olsen, President, Digital Equipment, 1977 US computer engineer & industrialist ( )

3 Dial Up vs. Broadband Dial Up What Is Dial Up? of or pertaining to a terminal that links to a computer by dialing a telephone number. -

4 Dial Up vs. Broadband Dial Up You Use Modem to connect to a Dial Up service, such as NetZero, Earthlink and America On Line (AOL) Speed is limited to 56 kilobits per second, which is very slow by today s standards. Is more portable than Broadband. Costs much less than Broadband. (Net Zero cost $9.95/month for basic service.) Dial Up is good for Web Mail and light surfing of the Internet.

5 Dial Up vs. Broadband - Broadband What is Broadband? In communications technology, the ability to send many signals over a single cable or other such communication medium. Broadband technology allows enormous amounts of data, such as that for movie videos, to be transferred over limited information infrastructure.

6 Dial Up vs. Broadband - Broadband Simply put, Broadband is a high speed internet connection The most common types of Broadband access are Cable and DSL.

7 Cable Modem Cable Modem is available from Cable Television Companies. Cable Modem is generally faster than DSL. Cable bandwidth is shared among a neighborhood while DSL is a dedicated connection. Cable Modem is usually more expensive than DSL. Uses your Cable Television Cables.

8 DSL or Digital Subscriber Line DSL is available from Telephone companies. Is available is various speeds, all generally slower than Cable. Uses your existing telephone wires. Requires use of a DSL Filter on the other phone lines in your home. Is generally cheaper than Cable Modem.

9 DSL or Cable? Which to Choose Both services are not necessarily available in your neighborhood. What are you going to do with it? Both service types will let you access Rowan Resources.

10 Sharing Computers in Your Home Sharing a High Speed Internet connection requires the use of a router. You can also purchase a router that contains a wireless access point to create a wireless network. I recommend a Linksys brand router/access point, such as the Linksys g Wireless Router, Model: WRT54G (approximately $70). We will discuss securing your wireless router later in the session.

20 Home Directory and Open Areas To connect to the Home Directories (H Drives) and Open Areas Rowan uses Native File Access, or NFA. NFA uses the operating system s built in method for accessing network drives. A full explanation of NFA, including directions, can be found at

21 NFA The first step to accessing remote drives is to know where you are going. To find your Home Directory, go to

22 MyHome Information Important: In order to connect to your files from your home computer you MUST be connected to the University using the VPN client. For instructions on downloading and installing the VPN client, and connecting to your Home Directory and Openarea please visit: Technology Toolbox: Accessing your Files from Off-Campus Your full user Context:.fleischner.NSS.IR.Rowan Your Home Server:nwuser7.rowan.edu Home Volume:HOME7 Home Path:\\Employees\fleischner Connect to your home directory (Safari on Mac Only): afp://nwuser7.rowan.edu/home7/employees/fleischner Connect to your home directory (PC Only; Internet Explorer): \\nwuser7.rowan.edu\home7\employees\fleischner\ FTP Openarea FTP Connect to the Openarea (PC Only; Internet Explorer): \\neptune.rowan.edu\common\openarea Connect to the Openarea (Safari on Mac Only):afp://neptune.rowan.edu/COMMON/Openarea

23 Connecting to Home and Open Areas On a PC, Click Start - > Run. On a Mac, Click Go -> Connect to Server In the Open box, enter the Location of your Home Directory. \\nwuser7.rowan.edu\ In the Server Address box, enter the Location of your Home Directory nwuser7.rowan.edu

24 Connecting to Home and Open Areas Once you click OK (Connect on a Mac), you will be prompted for your Rowan Network Username and Password. On a Mac, you will get a Volumes window. Select your volume (in my case, home7). On both a PC and Mac, a folder window will open. Double-click on your folder until you see your files.

25 Connecting to Home and Open Areas To connect to the Open Area, follow the previous steps, then enter \\neptune.rowan.edu or neptune.rowan.edu. Double-click on the COMMON folder, then double click on the openarea folder. Finally, find your folder and open it!

26 Creating Shortcuts Why repeat this process every time when we can easily create a short cut to our folder? To create a shortcut (PC), repeat the following process, but stop open folders one level before your files. (For the Home Drive, this will be the Employees folder). Right click on the folder and click Create Shortcut. This will place a shortcut on your desktop.

27 Creating Shortcuts On a Mac, open to the same folder, and then, while holding down the Apple and Option keys, click on and drag the folder you are creating a shortcut to the desktop.

28 Map Your Locations! (PC Only) If you use these locations repeatedly, you can easily assign them a Drive Letter, such as C. (C is reserved to always be your primary hard drive.) From the open network drive window, click Tools -> Map Network Drive on the window. Enter the address of your network drive and assign it a letter like H or O. Click OK.

29 Securing Your Wireless It is VERY IMPORTANT that you secure your home wireless. Each model works a little differently, but works on the same premise. For today s example, we will be using a Linksys router. Start by accessing your router s configuration software by opening a web browser and entering the router s IP address.

30 Securing Your Wireless Linksys generally uses Netgear, another leading manufacturer, also uses this address. Enter the address into your browsers address bar and hit enter. On the Linksys, you will be prompted for a password. The default Linksys password is admin

31 Securing Your Wireless Step 1 Change the Password!

32 Securing Your Wireless Step 1 Change the Password! Click on the Administration tab. In the Router Password field, enter a new password. Repeat in the Re-enter to confirm field. Click Save Settings.

33 Securing Your Wireless Step 2 Name Your Network! Each wireless network has a unique name. On campus, we user RowanOpen or RowanWPA. Linksys and Netgear use their company names as default. This is the first thing a hacker will use to find an easy network to break into!

34 Securing Your Wireless Step 2 Name Your Network! Start securing your network by changing its name! The name of the Wireless Network is called the SSID. To change the name, click on the wireless tab, then click in the Wireless Network Name (SSID) field. Enter a new name, and then click Save Settings.

35 Securing Your Wireless Step 2 Name Your Network!

36 Securing Your Wireless Step 3 Limit Machine Access! Next, we are going to limit who can access your network. This is a very simple and easy type of security, but it does NOT encrypt your data! To limit access, we are going to set a Wireless MAC Filter. To start we need the MAC address of the machines that are going to access your network.

37 Securing Your Wireless Step 3 What is a MAC Address? A Media Access Control address (MAC address) is a unique identifier attached to most network adapters (NICs). It is a number that acts like a name for a particular network adapter. The MAC address is made up of a series of hexadecimal numbers such as the following: 00:0B:DB:94:3A:16

38 Securing Your Wireless Step 3 Find Your Mac Address(PC) On a PC, click Start Run. In the Open box, type CMD and then click OK. At the prompt, type ipconfig /all and hit enter. You will get a listing of the machine s network adapters, along with any active IP address and the adapters Physical Address. Write down the physical address of any machine that will access your wireless network.

39 Securing Your Wireless Step 3 Find Your Mac Address(Mac) On a Mac, Click Apple System Preferences on the Finder menu to open the System Preference Window. Click on Network. In the Show dialogue, click Airport The machine s Mac address will be displayed at the Airport ID. Write down this address.

Remember, you ve changed your password! Click on the Wireless tab, and then click on the Wireless MAC filter sub-tab. Click Enable next to the Wireless MAC filter item.

42 Securing Your Wireless Step 3 Limit Machine Access! Click Permit Only PC s listed to access the wireless network. Click Save Settings. At this point, no computers can connect to your network. You need to add them to the MAC filter list. Click the Edit MAC filter list button.

43 Securing Your Wireless Step 3 In the following fields, enter the Mac Address of each computer that will be accessing your network. When you are done, scroll to the bottom and click Save Settings Limit Machine Access!

44 Securing Your Wireless Step 4 Hide in Plain Sight! Before finishing, you should start and connect every computer you will be using on the wireless network. This will ensure that these machines know what network to connect to. After each machine is connected, return to the router configuration screen. Click on the Wireless tab to return to the Basic Wireless Settings screen.

45 Securing Your Wireless Step 4 Hide in Plain Sight!

46 Securing Your Wireless Step 4 Hide in Plain Sight! On the Basic Wireless Settings screen, select Disable next to the Wireless SSID Broadcast item. This will keep the access point from broadcasting the name of your network, hiding it from network sniffing devices. This will hide your network in plain sight.

47 Advanced Security In addition to the above methods, you can use other advanced methods such as: Pre Shared Key - A pre-shared key or PSK is a secret which was previously shared between the two parties using some secure channel before it needs to be used. WEP Uses a standard 40-bit key to encode data.

48 Final Comments Finally, the best thing you can do is to practice safe computing techniques. Keep Virus scanning software up to date. Scan regularly for Spyware and Ad-Ware. Practice Safe Surfing techniques
