  Cyber ranges are virtual training ranges that have emerged as indispensable
environments for conducting secure exercises and simulating real or
hypothetical scenarios. These complex computational infrastructures enable the
simulation of attacks, facilitating the evaluation of defense tools and
methodologies and developing novel countermeasures against threats. One of the
main challenges of cyber range scalability is the exercise evaluation that
often requires the manual intervention of human operators, the White team. This
paper proposes a novel approach that uses Blue and Red team reports and
well-known databases to automate the evaluation and assessment of the exercise
outcomes, overcoming the limitations of existing assessment models. Our
proposal encompasses evaluating various aspects and metrics, explicitly
emphasizing Blue Teams' actions and strategies and allowing the automated
generation of their cyber posture.
