204 Part IV: Hacking Operating Systems Figure 11-1: Port scanning a Windows 7 system with NetScan Tools Pro. 2. Perform OS enumeration (such as scanning for shares and specific OS versions) by using an all-in-one assessment tool, such as LanGuard. Figure 11-2 shows a LanGuard scan that reveals the server version, vulnerabilities, open ports, and more. If you need to quickly identify the specific version of Windows that’s running, you can use Nmap (http://nmap.org/download.html) with the -O option, as shown in Figure 11-3. Other OS fingerprinting tools are available, but I’ve found Nmap to be one of the most accurate. 3. Determine potential security vulnerabilities. This is subjective and might vary from system to system, but what you want to look for are interesting services and applications and proceed from there.
Figure 11-2: Gathering detailed vulnerabilities of a Windows 2000 Server with LanGuard. Figure 11-3: Using Nmap to determine the Windows version. Chapter 11: Windows Countermeasures against system scanning You can prevent an external attacker or malicious internal user from gathering certain information about your Windows systems by implementing the proper security settings on your network and on the Windows hosts. You have the following options: ✓ Use a network firewall or web application firewall (WAF). ✓ Use the Windows Firewall or other personal firewall software on each system. You want to block the Windows networking ports for RPC (port 135) and NetBIOS (ports 137–139 and 445). ✓ Disable unnecessary services so that they don’t appear when a connection is made. 205
