Such information incorporates artifacts, for example, process lists, connection information, files stored, registry information, etc. we can use [dir] command to check the file is created or not. The order of volatility from most volatile to least volatile is: Data in cache memory, including the processor cache and hard drive cache. Examples of non-volatile data are emails, word processing documents, spreadsheets and various "deleted" files. Volatile data is the data that is usually stored in cache memory or RAM. Firewall Assurance/Testing with HPing 82 25. Make a bit-by-bit copy (bit-stream) of the systems hard drive which captures every bit on the hard drive, including slack space, unallocated space, and the swap file. Additionally, in my experience, customers get that warm fuzzy feeling when you can Once on-site at a customer location, its important to sit down with the customer Attackers may give malicious software names that seem harmless.
