The science of Computer Forensics was created in order to help various types of investigations polices for quick and reliable collection of digital data from electronic media (Computers, mobile phones, printers, etc.) of the suspect and their presentation in court.
The Open Computer Forensics Architecture it is a program which was created by the Dutch police to speed up the police investigation, automate the digital data collection process and enable 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 Open Computer Forensics Architecture to computer the suspect can be easily found and recovery 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 OCFA Anycast Relay messaging system, which is responsible for caching and storing unsent messages and for balancing load between the same type of OCFA components. On the second level, OCFA XML Router distributes the evidence to the appropriate sections of the OCFA. For distributing the data, the XML Router sees the meta data from the previous segments.
Although OCFA is simple to use, its capabilities are highlighted in its specialized use and architecture.
The last OCFA tool is the OCFA Data Store Module. This tool processes the data and meta data and stores the useful information in a database. OCFA can be downloaded by anyone who wants it from the page http://ocfa.sourceforge.net/ since it is free.
