Last week CLEI was held in Argentina. We had the opportunity to present a paper related to Zero Trust Architecture and a talk about our advances in Quantum Software security.

About Zero Trust Architecture:

Zero Trust Architecture (ZTA) is a novel security approach for building secure systems.
ZTA-based systems are built with specific security mechanisms to enforce their basic tenets, for example, explicit verification and least privilege. Although existing security mechanisms have been useful in building ZTA-based systems, the current literature does not provide clear guidance on which security mechanisms should be used by developers of these systems. This article describes the design and results of a systematic mapping study to identify the security mechanisms used in the building of ZTA-based systems. The review yielded 290 articles, of which 30 primary studies were selected. Key findings are: (i) 24 different security mechanisms were reported; (ii) 37\% of them are classified into access control techniques to implement ZTA least priveleges tenet; (iii) ABAC and AIM are the most used mechanisms; (iv) over half of security mechanisms (69\%) focus on resisting attacks (instead of detecting or recovering); and (v) experimentation is a predominant empirical strategy within ZTA security research. The identification of these security mechanisms will enable developers of ZTA-based systems to effectively address the security challenges associated with implementing ZTA tenets.

About Quantum Software security:

In this talk at the first Latin American Workshop on Quantum Software Engineering we describe our research progress on the secure design decisions we have detected in quantum software by identifying topics in quantum software projects on Github.
