These similarities serve as baselines to detect suspicious events. Volatile data is impermanent elusive data, which makes this type of data more difficult to recover and analyze. Related content: Read our guide to digital forensics tools. Two types of data are typically collected in data forensics. Webforensic process and model in the cloud; data acquisition; digital evidence management, presentation, and court preparation; analysis of digital evidence; and forensics as a service (FaaS). Digital forensics and incident response (DFIR) analysts constantly face the challenge of quickly acquiring and extracting value from raw digital evidence. In computer forensics, the devices that digital experts are imaging are static storage devices, which means you will obtain the same image every time. can retrieve data from the computer directly via its normal interface if the evidence needed exists only in the form of volatile data. With Volatility, this process can be applied against hibernation files, crash dumps, pagefiles, and swap files. Digital forensics is also useful in the aftermath of an attack, to provide information required by auditors, legal teams, or law enforcement.
