Accessing your home server from outside your local network is usually done by forwarding a port of your server through the router. This note describes a different approach allowing to establish a peer-to-peer connection between hosts on different private networks without having access to the router.

This talk hold in Riga at DSS ITSEC 2018 – 9th Annual International Cyber Security Conference is about technology assessement and a case study evaluating the suitability of Rust in Digital Forensics.

Within the framework of this study the suitability of the Rust ecosystem for forensic tool development was evaluated. As case study, the tool Strings­ext was developed. Starting from analysing the specific requirements of forensic software in general and those of the present case study, all stages of the software development life-cycle have been executed, up to the first production release.

Here you find a selection of some of my Bash scripts that you may find useful. I wrote them many ago and they are still in use.

This note explains how to set up a cheap Raid 1 NAS with an Odroid or Rasbperry board and two USB-harddisks using OpenMediaVault. Only very cheap and largely available hardware components are used. When very high availability is required it is recommended to hold available a second Oroid/Rasbperry board with a mirrored SD-card containing the NAS operating system. In this way the system has no single point of failure.
