The use of internet in Indonesia is increasing rapidly. More than thirty million people in Indonesia use internet as a media for business, education, entertainment, and other social interactions. The misuse of internet, as known as cyber crime, also increases. There are sort of events that trigger the occurrence of cyber crime. Based on that situation, the government has formed a national CSIRT called ID-SIRTII (Indonesia Security Incident Response Team on Internet Infrastructure) in 2007 to invigilate the network security based on internet protocol. The missions of ID-SIRTII are to control, to prevent, and to help the enforcement of law if the cyber crime happened. ID-SIRTII, as an institution that control and prevent cyber crime should have several research laboratories such as Digital Forensics Laboratory, Malware Analysis Laboratory, and Hacking Laboratory. This thesis is purposeful to help ID-SIRTII in designing the Digital Forensics Laboratory.
