Lab 8.4.3 Performing a Vulnerability Analysis

CAUTION: This lab may violate legal and organizational security policies. The security analyzer downloaded in this lab should only be used for instructional purposes in a lab environment. Before using a security analyzer on a live network, check with your instructor and network administration staff regarding internal policies concerning the use of these tools.
Objectives
• Download and install security analyzer software.
• Test a host to determine potential security vulnerabilities.
Background / Preparation
Security analyzers are valuable tools used by network administrators and auditors to identify network and host vulnerabilities. There are many vulnerability analysis tools, also known as security scanners, available to test host and network security. In this lab, you will download and install the Microsoft Baseline Security Analyzer (MBSA). MBSA is designed to identify potential security issues related specifically to Microsoft operating systems, updates, and applications. It also identifies unnecessary services that may be running, as well as any open ports.
MBSA runs on Windows Server and Windows XP systems and scans for common security misconfigurations and missing security updates for the operating system as well as most versions of Internet Information Server (IIS), SQL Server, Internet Explorer (IE), and Office products. MBSA offers specific recommendations to correct potential problems.
This lab can be done individually or in teams of two.
The following resources are required:
• Computer running Windows XP Professional to act as the test station.
• High-speed Internet connection for downloading MBSA (unless pre-installed).
• Computer must be attached to the integrated router switch or a standalone hub or switch.
• Optionally, you can have a server running a combination of DHCP, HTTP, FTP, and Telnet (preconfigured).
Step 1: Download and install MBSA
1. Open a browser and go to the MBSA web page at: http://www.microsoft.com/technet/security/tools/mbsa2/default.mspx
2. What is the latest version of MBSA available? Versi terakhir ialah MBSA 2.2
3. What are some of the features MBSA provides?
Answer:
• Command-line and Graphical User Interface (GUI) options
• Scan local computer, remote computer, or groups of computer
• Scan against Microsoft’s maintained list of updates (on Microsoft.com) or local server running Software Update Services 1.0
• Scan for common security configuration vulnerabilitie
• Scan for missing security updates
• View reports in MBSA Graphical User Interface or Command Line Interface
• Compatibility with SMS 2.0 and 2003 Software Update Services Feature Pack
• Support for single processor and multiprocessor configurations
• Localized to English, French, German, and Japanese although MBSA 1.2.1 can scan a machine of any local
1. Scroll down the page and select the desired language to begin the download process.
2. Click Continue to validate the copy of Microsoft Windows you are running.
3. Click Download Files below and select the file you want to download. (The English setup file is MBSASetup-EN.msi). Click the Download button on the right of this file. How many megabytes is the file to download?
Jawaban = kapasitas nya ialah 8,4 MB
1. When the File Download – Security Warning dialog box displays, click Save and download the file to a specified folder or the desktop. You can also run it from the download website.
2. Once the download is complete, make sure all other applications are closed. Double-click the downloaded file. Click Run to start the Setup program, and then click Run if you are prompted with a Security Warning. Click Next on the MBSA Setup screen.
3. Select the radio button to accept the license agreement and click Next. Accept the defaults as the install progresses, and then click Finish. Click OK on the final MBSA Setup screen, and close the folder to return to the Windows desktop.

Step 2: Build the network and configure the hosts
1. 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.
2. 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.
3. 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
• IP address : 192.168.1.2
• Subnet mask : 255.255.255.0
Step 3: Run MBSA on a host
1. Double-click the desktop icon for MBSA or run it from Start > All Programs. When the main screen displays, which options are available?
jawaban
• Pick a computer to scan
• Pick multiple computer to scan
• Pick a security report to view
• Help
• About
• Microsoft Security Web Site

Step 4: Select a computer to scan
1. On the left side of the screen, click Pick a computer to scan. The computer shown as the default is the one on which MBSA is installed.
2. What are the two ways to specify a computer to be scanned?
jawaban
• Scan using assign Update Services servers only
• Scan using Microsoft Update only
1. 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
1. View the security report. What are the results of the security update scan
Jawaban= tidak ada masalah apa apa
1. If there are any red or yellow Xs, click How to correct this. Which solution is recommended?
Jawaban = Tidak muncul red atau yellow Xs
Step 6: View Windows scan results in the security report
1. Scroll down to view the second section of the report that shows Windows Scan Results. Were there any administrative vulnerabilities identified?
Jawaban = Local Account Password Test, Automatic Update, Guest Account, File system.
1. On the Additional System Information section of the screen (below), in the Issue column for Services, click What was scanned, and click Result details under the Result column to get a description of the check that was run. What did you find? When finished, close both popup windows to return to the security report.
Step 7: View Desktop Application Scan Results in the Security report
1. Scroll down to view the last section of the report that shows Desktop Applications Scan Results. Were there any administrative vulnerabilities identified?
Jawaban = Macro security
