Resumo:
Embedded systems are crucial in various computing domains, from consumer electronics
to industrial automation, but they also pose significant cybersecurity challenges. This work
conducts an analysis of the current state of security requirements engineering for embedded
systems and explores cybersecurity solutions tailored for them. Specific security concerns in
embedded environments are addressed, leading to the proposal of a framework for modeling
and documenting the security architecture of embedded systems. This framework aims
to facilitate the integration of security requirements in projects involving firmware and
hardware. Factors considered include security requirements fulfillment, hardware resource
availability, performance overhead, compatibility, and ease of integration. Through a
systematic evaluation, this article aims to provide practical guidance for researchers
and practitioners in selecting effective cybersecurity solutions for embedded systems and
modeling them comprehensively for improved software quality through documentation.
