Cyber-Physical Systems (CPS) are software and hardware systems that interact with the physical environment. Many CPSs have useful lifetimes measured in decades. This leads to unique concerns regarding security and longevity of software designed for CPSs which are exacerbated by the need for CPSs to adapt to ecosystem changes if they are to remain functional over extended periods. In particular, the software in long-lifetime CPSs must adapt to unanticipated trends in environmental conditions, aging effects on mechanical systems, and component upgrades and modifications. This paper presents the Toolkit for Evolving Ecosystem Envelopes (TEEE) system created to help address these challenges in CPSs. TEEE is able to detect environmental changes which have caused errors within the CPS without directly sensing the environmental change. TEEE uses dynamic profiling to detect the errors within the CPS, determine the root cause of the error, alert the user, and suggest a possible adaption.
