Acquiring non-volatile evidence

Although there is a great deal of data running in memory, it is still important to acquire the hard drive from a potentially compromised system. There is a great deal of evidence on these devices, even in the case of malware or other exploitation. Hard drive evidence becomes even more important when examining potential incidents such as internal malicious action or data loss. To ensure that this evidence is available and can be utilized in a court of law, incident responders should be well versed in the procedures we've discussed in this chapter.

In certain circumstances, incident responders may want to acquire two key pieces of data from suspected compromised systems before shutting down a running system. While not volatile in nature, the registry keys and event log files can aid analysts during their investigation. Acquiring these files from...
