BHS Digital Forensics Technology
Technology supporting evidence handling, digital investigation, reporting and forensic laboratory operations.
Digital investigation challenges
Evidence is everywhere, and it has to hold up
Digital investigation now touches almost every kind of case, from cybercrime and financial crime to trafficking, terrorism and corporate wrongdoing.
- Evidence is spread across computers, mobile devices, networks, cloud services and connected systems, and rarely sits in one place.
- Data volumes per case keep rising, while the time available to work a case does not.
- Evidence has to survive scrutiny — provenance, integrity and chain of custody matter as much as the finding itself.
- Investigations increasingly cross jurisdictions, organizations and legal frameworks.
- Encryption, anti-forensic behaviour and short-lived data make acquisition time-critical.
- Laboratories and investigation teams need consistent process and reporting, not results that depend on who ran the examination.
Capability portfolio
Capability areas, described at a high level
BHS describes its digital forensics technology by capability area. What applies to a given laboratory or investigation team is established in a technical briefing.
Mobile & device forensics
Examination of mobile devices and other endpoints, where lawfully permitted and technically feasible.
Network forensics
Reconstruction of activity from network and log evidence.
Cloud forensics
Investigation of activity and artefacts held in cloud and hosted services.
Memory forensics
Analysis of volatile system state captured during an incident.
Malware analysis
Understanding hostile code and what it did in the environment.
Digital evidence management
Custody, integrity and traceability of evidence across a case.
Data recovery
Recovery of information from damaged, deleted or partially available sources.
Digital forensics capability is used within the legal authority that applies to the organization operating it. BHS technology supports lawful investigation and does not substitute for that authority.
Evidence workflows
Custody and integrity from acquisition to report
The evidence workflow is the backbone of the technology: every step is recorded, and every finding can be traced back to the item it came from.
- 01IdentifyEstablish what evidence exists, where it sits and what may be lawfully acquired.
- 02AcquireCapture evidence in a controlled way, with integrity recorded at the point of acquisition.
- 03PreserveHold evidence securely with custody, access and integrity tracked throughout.
- 04ExamineWork on verified copies using documented, repeatable process.
- 05AnalyseCorrelate findings across sources to build a defensible picture.
- 06ReportProduce findings in a form that stands up to technical and legal review.
Investigation workflows
A case, not a pile of examinations
Case management keeps tasking, progress, findings and review in one place, so a supervisor can see the state of every case the team is carrying.
- 01Case intakeRegister the case, its scope, its authority and the people permitted to work it.
- 02TaskingAssign examinations and actions to examiners with the relevant capability.
- 03ExaminationTrack work in progress against each item of evidence in the case.
- 04CorrelationBring findings from separate sources together into a single case picture.
- 05ReviewTechnical and supervisory review before findings leave the team.
- 06ClosureClose the case with a complete record of what was done, by whom and when.
Reporting & laboratory integration
Findings that survive review
Consistent, traceable, reviewable
- Consistent report structure across examiners, cases and laboratories.
- Findings traceable back to the evidence and the examination that produced them.
- A complete audit record of custody, access and actions taken on each item.
- Output suitable for investigative, legal and organizational audiences.
- Review and approval steps before a report is issued.
Built for how a forensic laboratory runs
- Case and evidence flow through the laboratory, from submission to return or disposal.
- Role-based access matched to laboratory functions and supervisory responsibility.
- Consistent process across examiners so results do not depend on the individual.
- Records that support laboratory quality, audit and accreditation processes.
- Integration with existing laboratory systems and equipment, scoped case by case.
Deployment & training
Getting the capability into use
Scoped to the team and the casework
Deployment is planned with the organization: the laboratories, units or field teams in scope, the roles that use the technology, the evidence-handling rules that apply and the hosting arrangement appropriate to the material involved.
Integration with existing laboratory systems, equipment and case systems is assessed as part of that work and delivered through BHS systems integration.
Capability, not just software
Technology only produces defensible results in the hands of trained examiners. BHS provides digital-forensics and technology-operation training alongside deployment, including process, evidence handling and reporting practice.
