Step 2: Build the network and configure the hosts 
a. Connect the host computer(s) to the integrated router, a hub, or a switch as shown in the topology diagram. Host-A is the test station where MBSA will be installed. The server is optional. 
b. Set the IP configuration for the host(s) using Windows XP Network Connections and TCP/IP properties. If the host is connected to the integrated router, configure it as a DHCP client; otherwise go to Step 1d. 
c. If the host is connected to a hub or switch and a DHCP server is not available, configure it manually by assigning a static IP address. Which IP address and subnet mask does Host-A and the server (optional) have?
Jawaban : 192.168.1.X and 255.255.255.0. Default gateway is not required but could be set to 192.168.1.1 (the default IP address of the integrated router, if present). 
IP Address : 192.168.24.09
Subnet Mask : 255.255.255.0


Step 3: Run MBSA on a host 
a. Double-click the desktop icon for MBSA or run it from Start > All Programs. When the main screen displays, which options are available?

b. What are the two ways to specify a computer to be scanned? 
Jawaban : By name and by IP address. 
c. Accept the default computer to be scanned. De-select Check for IIS and SQL administrative vulnerabilities, since these services are not likely to be installed on the computer being scanned. Click Start Scan.


Step 5: View security update scan results 
a. View the security report. What are the results of the security update scan? 
Jawaban : See screen below for possibilities. Missing Security Updates are indicated by a red X in the Scorecolumn. Missing Update Rollups and Service Packs are indicated by a yellow X

a. If a server with various services is available, click Pick a computer to scan from the main MBSA screen and enter the IP address of the server, and then click Start Scan. Which security vulnerabilities were identified?
Jawaban : This can be a live server if the host has physical and logical access to it and organizational policies permit scanning the live network 
b. Were there any potentially unnecessary services installed? Which port numbers were they on?
Jawaban : Could include Telnet, HTTP, FTP, and so on, with corresponding port numbers


Step 9: Uninstall MBSA using Control Panel Add/Remove Programs 
a. This step is optional, depending on whether the host will be automatically restored later by a network process.
