Digital Forensics Services

What is Digital Forensics

Digital forensics in industrial cybersecurity involves the systematic identification, preservation, collection, analysis, and reporting of digital evidence related to cybersecurity incidents within industrial (OT) and enterprise (IT) environments.

The importance of forensic services spans law enforcement, corporate security, legal  proceedings, data recovery, and the protection of individual and national interests in an increasingly digital and interconnected world.

Digital Forensics: Scenarios

Digital forensics examines logs, access records, and system changes to identify malicious activity. By analyzing system data and communications, it provides concrete evidence for legal or disciplinary actions.

The forensic team investigates how the attacker gained access, what security flaws were exploited, and whether any critical data or credentials were compromised. This involves reviewing firewall logs, VPN connections, and user activity to identify the entry point and mitigate future risks.

 

A digital forensic investigation isolates the malware's origin, examines its spread through IT and OT systems, and identifies any stolen sensitive patient data. By reconstructing the attack timeline, the forensic team can prevent recurrence and guide post-incident recovery.

Forensic experts analyze data flow, firewall logs, and employee device activity to trace the network breach and identify stolen data. The investigation focuses on tracking internal and external communications to identify and close the breach source.

 

Forensic analysis investigates whether commands were due to operator error or unauthorized access. This involves analyzing system logs, communication channels, and historical data to determine if cyber sabotage or insider manipulation was involved.

Methodology of Digital Forensics

The methodology involves a structured approach, starting with the identification of evidence sources. It continues with the preservation, collection, and thorough examination of data to uncover pertinent information. The subsequent steps include analysis, documentation, and the presentation of findings to provide a comprehensive overview of the digital investigation. The process concludes with reporting, archiving, and the provision of feedback for security improvement based on the forensic analysis results.

     Identify potential sources of relevant evidence and determine where that data is located.

     Preserve electronically stored information (ESI) and document key details about the evidence and its acquisition process.

     Collect digital information pertinent to the investigation or incident, including IT and OT data and network log files.
