However, technological evolution and the emergence of more sophisticated attacks prompted developments in computer forensics. At the start of the investigation process, you need to differentiate between persistent and volatile data. Volatile Data Collection. Since the nature of volatile data is effervescent, collection of this information will likely need to occur in real or near-real time. VOLATILE DATA COLLECTION METHODOLOGY u Prior to running utilities on a live system, assess them on a test computer to document their potential impact on an evidentiary system. Volatile Data : Volatile data is stored in memory of a live system (or in transit on a data bus) and would be lost when the system was powered down. Two basic types of data are collected in computer forensics. Fig.1 shows different steps of cloud forensics. There are two types of data collected in Computer Forensics Persistent data and Volatile data. Persistent data is that data that is stored on a local hard drive and it is preserved when the computer is OFF. Volatile data is any kind of data that is stored in memory, which will be lost when computer power or OFF. • Example: Host compromise - Volatile data can show established connections. Forensic image.
