EVIDENCE-LED INVESTIGATION · ADVANCED CYBER SECURITY

Digital Forensics

Reconstruct what happened. Understand what the evidence shows.

After a cyber incident, assumptions are not enough. ACS Digital Forensics applies investigative techniques to identify, preserve, examine and document digital evidence, helping organizations develop a clearer understanding of events.

Layered digital evidence reconstruction connected by a single blue trace

From scattered traces to an informed account

An incident can leave information across multiple electronic devices and systems. Digital forensics brings a structured approach to examining those traces: what can be established, how events relate to one another, and which questions remain unanswered. The emphasis is on evidence-led analysis and clear documentation, not conclusions that go beyond the available material.

Preserve & identify

Identify relevant sources of digital evidence and consider preservation requirements before material is altered or lost.

Extract & examine

Examine the electronic evidence within the agreed scope and investigate information relevant to the incident or question.

Reconstruct & document

Connect findings into a clearer account of activity, documenting what the evidence supports and where limitations remain.

A STRUCTURED APPROACH

From understanding to action

  1. Clarify the questions

    Agree what the investigation needs to establish, which systems or devices are in scope and what information is available.

  2. Handle the evidence

    Plan collection and preservation with attention to the integrity and documentation of the material being examined.

  3. Explain the findings

    Present an evidence-led account that supports organizational review and informed follow-up.

Clarity that supports the next step

Forensic analysis can support the understanding of digital attacks and other incidents, informing response, remediation and further investigation. The usefulness of an investigation depends on the evidence available and how it has been preserved. Where evidence may be needed for formal proceedings, the relevant handling and documentation requirements should be addressed from the outset.

A closer look

Does forensics only apply to computers?

Digital evidence can exist across different types of electronic devices and systems. The relevant sources are identified according to the investigation’s scope.

Can an investigation answer every question?

Not necessarily. Missing, altered or unavailable evidence can limit the conclusions. A careful investigation distinguishes established findings from uncertainty.
