What are some typical aspects of a computer forensics investigation? First, those who investigate computers have to understand the kind of potential evidence they are looking for in order to structure their search. Crimes involving a computer can range across the spectrum of criminal activity, from child pornography to theft of personal data to destruction of intellectual property. Second, the investigator must pick the appropriate tools to use. Files may have been deleted, damaged, or encrypted, and the investigator must be familiar with an array of methods and software to prevent further damage in the recovery process. Two basic types of data are collected in computer forensics. Persistent data is the data that is stored on a local hard drive (or another medium) and is preserved when the computer is turned off.
Volatile data is any data that is stored in memory, or exists in transit, that will be lost when the computer loses power or is turned off. Volatile data resides in registries, cache, and random access memory (RAM). Since volatile data is ephemeral, it is essential an investigator knows reliable ways to capture it.
System administrators and security personnel must also have a basic understanding of how routine computer and network administrative tasks can affect both the forensic process (the potential admissibility of evidence at court) and the subsequent ability to recover data that may be critical to the identification and analysis of a security incident.
