312 Part V: Hacking Applications Finding storage systems on the network To seek out storage-related vulnerabilities, you have to figure out what information is where. The best way to get rolling is to use a port scanner and, ideally, an all-in-one vulnerability scanner, such as QualysGuard or LanGuard. Also, given that many storage servers have web servers built in, you can use such tools as Acunetix Web Vulnerability Scanner and WebInspect to uncover web-based flaws. You can use these vulnerability scanners to gain good insight into areas that need further inspection, such as weak authentication, DNS server name pollution, unpatched operating systems, unprotected web servers, and so on. A commonly overlooked storage vulnerability is that many storage systems can be accessed from both the de-militarized zone (DMZ) segment and the internal network segment(s). This vulnerability poses risks to both sides of the network. Be sure to manually assess whether you can reach the DMZ from the internal network and vice versa. You can also perform basic file permission and share scans (as outlined in Chapter 11) in conjunction with a text search tool to uncover sensitive information that everyone on the network should not have access to. Rooting out sensitive text in network files An important authenticated test to run on your storage systems is to scan for sensitive information stored in readily accessible text files. It’s as simple as using a text search utility, such as FileLocator Pro or Effective File Search (www.sowsoft.com/search.htm). Alternatively, you can use Windows Explorer to scan for sensitive information, but it’s just too slow and cumbersome for my liking. You’ll be amazed at what you come across stored insecurely on users’ Windows desktops, server shares, and more, such as ✓ Employee health records ✓ Customer credit card numbers ✓ Corporate financial reports Such sensitive information should not only be protected by good business practices, but is also governed by state, federal, and international regulations. Do your searches for sensitive text while you’re logged in to the local system or domain as a regular user — not as an administrator. This will give you a better view of regular users who have unauthorized access to sensitive files and shares that you thought were otherwise secure. When using a basic text search tool, such as FileLocator Pro, look for the following text strings:
Figure 15-3: Using FileLocator Pro to search for sensitive text on unprotected shares. ✓ DOB (for dates of birth) ✓ SSN (for Social Security numbers) ✓ License (for driver’s license information) ✓ Credit or CCV (for credit card numbers) Chapter 15: Databases and Storage Systems Don’t forget about your mobile devices when seeking sensitive, unprotected information. Everything from laptops to USB drives to external hard drives is fair game to the bad guys. A misplaced or stolen system is all it takes to create a costly data breach. The possibilities for information exposure are endless; just start with the basics and only peek into nonbinary files that you know will have text in them. Limiting your search to these text-based files will save you a ton of time! ✓ .txt ✓ .doc and .docx ✓ .dbf ✓ .db ✓ .rtf ✓ .xls and .xlsx An example of a basic text search using FileLocator Pro is shown in Figure 15-3. Note the files found in different locations on the server. 313
