University of Portsmouth: Survey into Legacy Systems
The aim of this questionnaire is to study the implications of legacy systems in contrast with our modern technology and forensic techniques. With todays technology significantly evolving the use of older technologies has become almost outdated. However these systems could still be holding valuable data.
The questionnaire is intended for Computer Forensic Technicians. With your cooperation you will help to conclude whether legacy systems and devices cause limitations if involved with current investigations. This questionnaire is designed to find out the frequency of theses old legacy systems and whether modern forensics are still capable of extracting and analysing data from these systems in terms of legacy structural knowledge and compatibilities.
It is a short anonymous questionnaire and will not take up much time. The questions are designed to collect opinions and current frequencies/methods for investigating legacy evidence.
