Computer Forensics
From the mid-eighties on, the
NFI (formerly the Forensic Science Laboratory) has been involved in the
field of Digital Evidence. The Department of Digital Technology consists
of 25 staff members, most of which are university level engineers in IT
and Electronics. They work on the following areas:
-
Open Systems (all operating
systems, files systems, media formats, hacking & security)
-
Embedded Systems (organisers,
telephones, smart cards, car electronics)
-
Data Communication (all
digital communication, including internet)
-
Digital Imaging (digital
methods for analysing video material)
The skills involved are software
skills, hardware skills, cryptographic skills and interpretative skills.
The NFI is a part of the Ministry
of Justice and is independent of police and prosecution. It works for police,
prosecution and defence. It produces expert witness reports for the courts,
as well as technical support for prosecution and police. For instance, all
internet interceptions of Dutch Law enforcement are currently carried out
with solutions which have been developed at NFI/DT. Some of the products
are shipped world wide, like ZERT2 (a solution to crack many popular organisers)
and Cards4Labs (a solution for accessing the contents of smart cards.
The subject of the presentation
will be Forensic IT. Examples of Digital Evidence and its role will be given.
Both strengths and weaknesses and as a result the future role of Digital
Evidence will be addressed. Furthermore, the set-up of Digital Evidence
units (police or forensics), materials and skills required, and some important
pitfalls will be addressed.
