IT Forensics – Windows

Forensic analysis of Windows Firewall artefacts – tracing network communication and configuration changes

The Windows Firewall protects systems from unauthorised network connections and, depending on the configuration, logs various security-related details. As part of an IT forensic investigation, firewall configurations, rules and logs can provide important clues regarding network communication, system changes or attempts at tampering.

Enquire without obligation

A professional analysis is never carried out in isolation. Only by correlating the data with event logs, the Windows Registry, DNS artefacts, network protocols and other Windows artefacts is it possible to make a robust technical assessment.

Why LanCologne?

Since its foundation, LanCologne has specialised in professional IT forensics. Our staff have decades of experience in the field of information technology and assist companies, solicitors, private individuals and, on a regular basis, the courts in the technical investigation of complex digital matters.

The examination is carried out exclusively on a forensic copy or a forensic image. The original evidence remains unchanged and is stored in a manner that preserves its evidential integrity.

Our services

We analyse firewall rules, configuration changes and existing logs. The results are correlated with other network and Windows artefacts and fully documented.

Typical areas of application

•Incident Response
•Analysis of network attacks
•Investigation into potential malware
•Reconstruction of network communication
•Allegations of manipulation
•Expert reports for the courts

This is how the analysis works

Once a forensic image has been created, the relevant firewall artefacts are analysed. The results are then cross-referenced with other digital evidence and assessed from a technical perspective.

Why are Windows Firewall artefacts important?

Firewall configurations and logs can provide indications of permitted or blocked network connections, as well as changes to the security configuration. However, their significance only becomes apparent following a comprehensive analysis of all relevant digital traces.

Frequently Asked Questions

What information might Windows Firewall artefacts contain?+
Depending on the configuration, this includes, amongst other things, firewall rules, settings and protocols relating to network connections.
Is the original system being examined?+
No. Only a forensic copy or forensic image is analysed.
Are firewall logs always available?+
No. The scope and availability depend on the system configuration and the logging functions that have been enabled.
Are firewall artefacts alone sufficient for an expert report?+
No. They are always analysed in conjunction with other Windows and network artefacts.
