There are several locations where evidence are usually found such as in the hard drive on the user’s personal computer‚ laptop‚ smart phone or tablet (ACPO‚ 2012). It is also critical that forensics are aware of the intention of the particular investigation. This aids in the forensics’ efforts of locating digital evidences that are relevant to the case. For example‚ in the case of a server intrusion‚ forensics should look out for signs such as a rootkit installation‚ analyze configuration files‚ logs
