Such data is typically recovered from hard drives. The syscall is made with the sc instruction, and returns with execution continuing at the instruction following the sc instruction. This volatile data may contain crucial information.so this data is to be collected as soon as possible. Develop and implement a chain of custody, which is a process to track collected information and to preserve the integrity of the information. Also allows you to execute commands as per the need for data collection. These network tools enable a forensic investigator to effectively analyze network traffic. This type of procedure is usually named as live forensics. One approach to this issue is to tie an interrupt to a circuit that detects when the supply voltage is dropping, giving the processor a few milliseconds to store the non-volatile data.
