The increasing number of cyber-attacks, their potential destructive capabilities, and the enormous threat they pose for organizations, require the constant design and development of new, faster, and easier to use systems to address them. The automation of security enforcement systems is one of the most important techniques for enabling a fast response to security challenges, but the complexity of security management might hinder the successful achievement of the desired security. Our proposal integrates the automatic enforcement of security rules based on intrusion detection systems with the definition of a high-level user-centered language for the definition of policies. We have designed a translation process from this language to specific network-wise and device-aware rules that can be installed and enforced. The deployment of these rules is determined by an automatic risk assessment process ruled by the detection system monitoring the network. This way, both the automation and easiness of use goals can be achieved using an integrated system. The solution was tested and validated in two different virtualized networks.
