Embedded System Security with Rust

Real-time embedded systems have to meet a combination of requirements that are in deep tension: they are expected to deliver timely results, observing strict deadlines, all using only very limited resources, computing power and energy. To this day, the most common programming language in this environment is C/C++ because of its zero-cost abstractions and fine control over memory layout. With the upcoming communication ability through network interfaces, an additional requirement gained in importance: security. Unfortunately, C/C++ supports some secure software design principles only rudimentary. Too many very severe vulnerabilities are directly related to the fact that C/C++ does not guarantee memory safety. To exemplify this, the prominent Heartbleed vulnerability is discussed in terms of causes, technical details and impact.

Forensic-Tool Development with Rust

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. Strings­ext is a reimplementation and enhancement of the GNU-strings tool, a widely used program in forensic investigations. Strings­ext recognizes Cyrillic, CJKV characters and other scripts in all supported multi-byte-encodings while GNU-strings fails in finding these in UTF-16 and other encodings.

Stringsext

stringsext is a Unicode enhancement of the GNU strings tool with additional functionalities: stringsext recognizes Cyrillic, CJKV characters and other scripts in all supported multi-byte-encodings, while GNU strings fails in finding any of these scripts in UTF-16 and many other encodings.
