	abstract = {The objective of the proposed research is to develop a compositional framework and methods for~performance vs security tradeoffs via multi-criteria optimization of system security, and therefore it aligns~with problem statement 2: {\textquotedblleft}Security Framework.{\textquotedblright} We propose to study a top-down approach ~for~optimizing (1) the security metric(s) of a composite system viewed as a bivariate function of its~subsystems{\textquoteright} security and performance metrics under given constraints and (2) the composition of~subsystems that provides higher system security than that of the composition of the same subsystems~driven solely by performance maximization. In this way, we reconcile the trade-off between security and~performance by introducing a holistic, multi-objective solution that satisfies both the performance and the~security requirements for the system, by overcoming the problem of compartmentalized security solutions~and thus achieving the {\textquotedblleft}best value{\textquotedblright} of the system. Our framework delineates methods for achieving~provably secure composition of secure subsystems and system components {\textendash} a critical problem area~where almost all current results demonstrate infeasibility of achieving compositional security.},
