Process and Methodology
Our forensic processes utilize the standards set forth by the U.S. Department of Justice and the National Institute of Standards and Technology (NIST). The methodology is built on the following principles:
- The source data is unchanged whenever possible by utilizing NIST certified hardware/software write-block devices.
- Verification that the copied evidence is identical to the original via hash value comparison.
- Search and analysis of forensic evidence is performed using NIST certified software to ensure the analysis is accurate and repeatable.
