A new approach to the dynamic security assessment of power systems including relay performance
In this thesis, security assessment of a power system under large disturbances has been studied. A protective system (relays) has been included in the power system model and a new measure that quantitatively describes the dynamic reponse of the system together with a procedure to identify the set …

A Quantitative Security Assessment of Modern Cyber Attacks. A Framework for Quantifying Enterprise Security Risk Level Through System's Vulnerability Analysis by Detecting Known and Unknown Threats
Cisco 2014 Annual Security Report clearly outlines the evolution of the threat landscape and the increase of the number of attacks. The UK government in 2012 recognised the cyber threat as Tier-1 threat since about 50 government departments have been either subjected to an attack or a direct threat …
