Analysis of VoIP Forensics with Digital Evidence Procedure

The invention of Voice over Internet Protocol (VoIP) in communication technology created significant attractive services for its users, it also brings new security threats. Criminals exploit these security threats to perform illegal activities such as VoIP malicious attacks, this will require digital forensic investigators to detect and provide digital evidence. Finding digital evidence in VoIP malicious attacks is the most difficult task, due to its associated features with converged network. In this paper, a Model of investigating VoIP malicious attacks is proposed for forensic analysis. VoIP spoofing is being a common and most important threat to the VoIP users. It is technically possible for an attacker to masquerade as another VoIP caller (VoIP spoofing). A design of a SIP which will try to capture all of the data on a VoIP network and process it for forensic analysis with also detection of the spoofing or the fake caller address.
