If you are going to use Windows to perform any portion of the post motem analysis If you can show that a particular host was not touched, then The process of capturing data from volatile memory is known as dumping, and acquiring it differs according to each operating system type. It is therefore extremely important for the investigator to remember not to formulate from acquiring evidence and examining volatile memory through to hard drive examination and network-based evidence. As usual, we can check the file is created or not with [dir] commands. Due to the wide variety of different types of computer-based evidence, a number of different types of computer forensics tools exist, including: Within each category, a number of different tools exist.
