Digital Forensics – ISO 27001, ISO 17025, ISO 17020 – Compliance, Accreditation and Best Practice

The United Kingdom Accreditation Service (UKAS) accredits against ISO 17025 and ISO 17020 and this is seen as an integral part of the quality framework and an expectation for those supplying forensic science services.

ISO 17025 can be applied to accredit any general laboratory and ASCLD-LAB, special purpose forensic laboratories.

Digital forensics is also key in implementing and maintaining an effective information security management system (ISMS) as specified by the ISO27001.

Control A.13.2.3 of the ISO 27001 Standard requires: in the event of a security incident any evidence presented in a criminal or civil action against an individual or company must fully conform to all relevant legislation. While this requirement is fairly obvious, it is crucial to the success of the legal process that the digital evidence is collected as accurately and reliably as possible.

The best practice as defined in clause 13.2.3 of the ISO 27002 Code of Practice (not a management standard, only best practice, cannot be accredited) recommends the preparation of an investigation procedure which includes the forensic collection of digital evidence together with the originals of all documents and witness details.

All such plans are major contributors to ensuring conformance to Clause 7.3 of the ISO 27001 Standard on preventative action which is of course essential to the maintenance of the ISMS continual process improvement.
