Recorded live at the Ripple offices in London, February 2023
www.meetup.com/cpplondon/even...
This talk introduces Digital Security by Design, a UKRI led programme that aims to radically update the foundation of the insecure digital computing infrastructure by creating a new, more secure hardware and software ecosystem. For more information please visit our website, www.dsbd.tech/- This talk will walk-through CHERI, Morello and their potential for the future of cybersecurity. CHERI is a modified firmware that allows you to securely access CPU memory and isolate the memory access by permission. The Morello Board is an implementation of an Arm CPU architecture designed to be accessed by CHERI.- The CHERI Morello board aims to explicitly solve the C programming languages security weaknesses, specifically in regard to unauthorised memory access and the known exploits associated with it. This includes addressing the pointer’s functionality and introducing a new CPU-attached functionality called capabilities. In addition, it makes it easier to identify vulnerabilities in C and C++ legacy code and new developments. Another feature that the technology promotes is the possibility of protecting code through compartmentalisation, a granular form of process protection.
