There is no doubt that security is a constant concern for organizations. Furthermore, if these organizations use microservice architectures in their systems, security becomes an ongoing concern. To address security concerns, three critical quality attributes must be analyzed, which are integrity, confidentiality, and availability. Regarding this last one quality attribute, we conducted an empirical study where we identified design decisions (better known as architectural tactics) for availability with the aim of supporting security designs in microservices architectures (see the below Table).

This study will be presented in the 1st workshop on Designing and Measuring CyberSecurity in Software Architectures (DeMeSSA), held by the European Conference on Software Architecture (ECSA).
