Standards Bodies

  • US National Institute of Standards and Technology (NIST)
  • NIST has the program: Computer Forensic Tool Testing (CFTT)
  • ISO (ISO/IEC 27037:2012) (provides guidlines)
  • UK - Association of Chief Police Officers (ACPO) - Provides: ACPO Good Practice Guide for Digital Evidence
  • DOJ maintains Electronic Crime Scene Investigation: A Guide fo First Responders
  • Research journal (academic): Digital Investigation: The International Journal of Digital Forensic & Incident Response
  • Conference: Digital Forensics Research Workshop (DFRWS)

For the private sector

Open Source (Linux) vs Commercial forensic software

Advantages (Open Source)

  • Accessible to anyone
  • Examine the code is possible
  • No need to sign nondisclosure agreements
  • You can modify the source code
    • Easier to automate
    • You can more easily integrate with other software
    • You can modify the code to meet the requirements of a particular forensic lab
  • You have mailing lists, chat other types of forums
  • Ideal for academic
  • Development community work with each other even if tehy compete

Disadvantages (Open Source)

  • Support is not reliable nor accurate nor trustworty (at times)
    • Commercial software often have 24/7 support and is more reliable
  • Reaching out to the public to get help you could reveal sensitive information
  • Interoperability with proprietary technologies with open source is often incomplete or not implementing some function properly
  • Some project are abandoned or neglected (e.g.: OpenSSL)
  • When in court the commercial software company can defend their product
  • Open Source is better for educational reasons
