Forensic analysis of Samba shares – analysing network shares between Linux and Windows

Samba enables Linux file shares to be made available via the SMB/CIFS protocol and is frequently used to ensure interoperability between Linux and Windows clients in mixed network environments.

Enquire without obligation

When configured accordingly, Samba logs access events, authentication processes and, in some cases, file access to individual shares, which makes it possible to reconstruct share access.

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, as a matter of principle, carried out exclusively on a forensic copy, a forensic image or a data source captured in a technically equivalent manner that preserves the integrity of the evidence. The original evidence remains unchanged and is stored in a manner that preserves its integrity.

Our services

We analyse Samba configurations and existing access logs, and use this information to reconstruct which users accessed which shares and when.

Typical areas of application

Reconstruction of unauthorised access to network shares
Investigation of data leakage via Samba shares
Tracking changes to access rights for shared files
Analysis of mixed Windows-Linux network environments
Incident Response on Linux Systems
Judicial and non-judicial expert reports

This is how a Samba analysis works

Once the system has been secured, Samba configuration files and existing access and authentication logs are collected. These are systematically analysed to reconstruct access to individual shares, broken down by time and user.

Why is the Samba analysis relevant from a forensic perspective?

In mixed network environments, Samba shares are often a central repository for corporate data, which is why evidence of unauthorised access or a data breach can be particularly significant from a forensic perspective.

As access can occur via various client operating systems, the client-side context is always taken into account during the analysis in order to obtain a complete picture.

Frequently Asked Questions

What information does Samba typically log?+
Depending on the configuration, authentication processes, connection establishment and, in some cases, individual file accesses at share level.
Can access attempts be attributed to individual Windows users?+
Yes, provided that the relevant user authentication has been configured and the associated logs are available.
Is a Samba analysis also possible with domain integration?+
Yes, in such cases, the logs of the associated directory service are also taken into account.
