About Dr Z. Cliffe Schreuders

Cliffe completed his PhD in Computer Security at Murdoch University in Perth, Western Australia. There he gained experience teaching a wide range of subjects including computer security, software development (including amongst other languages: C, Java, and Perl), Linux / Unix system administration and security, IT project management and digital collaboration, and web development. Since 2012, Cliffe is a Senior Lecture in computer security at Leeds Beckett University, UK, where he develops curriculum and teaches a wide range of digital security topics, such as security theory and practice (including defence, investigation, and response), forensics, information security management, and ethical hacking.

Cliffe's research activities include security usability, developing new security models, and free and open software and culture media distribution (please refer to the section below for more about his research work). Cliffe is comfortable with a wide range of programming languages, and his experience includes Linux kernel and Qt/C++ development, and he has worked in industry on Linux-related software development.

Cliffe has specialist knowledge in computer security, and is an avid proponent of Linux, free and open source software (FOSS), and free culture.

Research Interests

Cliffe has a research track record within the field of computer security application-oriented access controls and sandboxing, which aims to provide more usable application restrictions. He developed a security model known as Functionality-Based Application Confinement (FBAC). This model provides application-oriented access controls, based on flexible policy abstractions that represent the functionalities an application performs, and which is well suited to automated policy specification. The implementation, known as FBAC-LSM, is a Linux Security Module and associated tools, and is available as free open source software. A usability study was conducted to compare its efficacy with other security systems such as AppArmor and SELinux. Cliffe has published papers in academic peer-reviewed journals and conferences, and also spoken at various Linux and security conferences and meetings.

Cliffe's recent research activities have also included work related to metadata and the semantic web, and he is currently working on a media distribution platform for free and open source software and cultural works. Cliffe is also actively investigating approaches to teaching computer security.
