Lab B.3: Turn on the Firewall in Windows XP: Method Two
This lab requires a Windows XP workstation.
To turn on the firewall, follow these steps:
1. Choose Start Control Panel Security Center. The dialog box shown in Figure B.3 appears.
Instead of choosing Security Center in Control Panel, you could choose Windows Firewall and immediately access the Firewall Configuration dialog box. The advantage of choosing Security Center is that you see the other options that are also available.
2. Toggle the setting for the firewall from Off to On.
3. Exit the Security Center.
4. Exit Control Panel.
Note that from this location, you can toggle the status of the firewall. If the firewall is already turned on, you can follow these same steps to turn it off should you need to.
FIGURE B.3 Firewall configuration appears first in the Security Center dialog box.
Lab B.4: Create a Baseline for Internet Access
This lab works with any workstation.
Creating a baseline involves gathering information about normal operations and then looking for deviations. A good baseline is constructed from collecting data on several variables. To collect information about Internet access speed from a workstation, follow these steps:
1. Open the workstation’s browser.
2. Set the URL to http://bandwidthplace.com/speedtest/.
3. Click the button to begin the test. The speed is returned to you within seconds.
4. Test the workstation from this site over the course of a few days, varying the time of day you do so in order to build a good baseline.
