Open Computer Forensics Architecture OCFA

Computer Forensics was created to assist various types of police investigations for fast and reliable digital collection from the electronic means (Computers, mobile phones, printers, etc.) of the suspect and their presentation in court.Open Computer Forensics Architecture OCFA

The Open Computer Forensics Architecture is a program created by the Dutch police to speed up the police ς, την αυτοματοποίηση της of digital data collection and enables police investigators to have continuous access to the case data that has been found up to that point.

Open Computer Forensics Architecture has been developed on Linux and requires good knowledge of SQL language and knowledge of Computer Forensics in general.

By connecting the Open Computer Forensics Architecture to the suspect's computer, it can be easily found and digital data that can be presented in court as evidence.

With OCFA's specialized use, data can be obtained that show information about a document or information that the suspect has attempted to delete. This data is called Meta Data.

Communication between the departments within the OCFA is determined by a communication system consisting of two levels.

At the first level there is the messaging system with το OCFA Anycast Relay το οποίο είναι υπεύθυνο για την messages and storing undelivered messages and for load balancing between segments of the same type within the OCFA. At the second level the OCFA XML Router distributes the evidence to the appropriate segments of the OCFA. To distribute the evidence the XML Router sees that recorded the meta data from the previous sections.

Although OCFA is simple to use, its capabilities are highlighted in its specialized use and architecture.

The last tool of OCFA is the OCFA Data Store Module. This tool processes the elements (data and meta data) and stores the useful information in a database. OCFA can be downloaded by anyone who wishes from the http://ocfa.sourceforge.net/ if it is free of charge.
