Systematically analysing home directories using forensic methods – comprehensively capturing user-related data

Home directories contain a wide range of user-related items, from configuration files, shell histories and application data to documents and downloaded files.

Enquire without obligation

A comprehensive forensic analysis requires the systematic identification of both visible and hidden files and directories, as relevant configuration and application data is often stored in hidden subdirectories.

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 systematically scan home directories, including hidden files and application directories, and assign the artefacts they contain to the relevant applications and usage contexts.

Typical areas of application

•Comprehensive recording of user-related data and configurations
•Detailed analysis of individual user activities
•Identification of hidden configuration and application data
•Preparing a comprehensive user timeline
•Incident Response on Linux Systems

This is how the systematic analysis of home directories works

Once the backup has been completed, every relevant home directory is systematically recorded, including hidden files and application directories. Any artefacts found are organised into categories such as shell configuration, application data and documents, and prepared for further topic-specific analysis.

Why is this systematic analysis forensically relevant?

Home directories often contain the highest concentration of user-specific forensic artefacts on a system and are therefore a key starting point for many user-related investigations.

An incomplete scan – for example, due to hidden directories being overlooked – may fail to take relevant configuration or application data into account, thereby skewing the analysis.

Frequently Asked Questions

What is typically found in a home directory?+
These include, amongst other things, Shell configurations, application data, documents, downloads and numerous hidden configuration directories for individual programmes.
Why are hidden files relevant in a forensic context?+
Many applications store configuration and history data in hidden directories, which are easily overlooked during a cursory scan.
Are all home directories treated the same?+
The focus of the investigation depends on the specific issue under consideration; however, as a general rule, all relevant accounts are systematically recorded.
