The Cost

The European water directive forced the Member States to rethink the regulation of water services. Water pricing is now guided by the cost recovery principle. The costs to take into account are manly the environmental and resource costs, but also the financial ones. Portugal was no exception. The evolution from a heavily subsidized activity to a business bound by the polluter pays principle required fast changes and a somewhat difficult adaptation both of economic agents and households.

Cyber Kill Chain

The paper documents, based mainly on [3]-[6] published papers where a consistent mathematical description of cyberspace and various types of Cyber-Attacks and protection measures are presented, a holistic mathematical approach to a rigorous description of Advanced Persistent Threat (APT) actors’ modus operandi through various scenarios and Cyber Kill Chain stages [2]. After referring [6] to the various elements of Cyber-Attacks we propose some techniques (via 5 scenarios) of tracking the modus operandi of the most sophisticated and non-linear cyber actors, the Advanced Persistent Threat actors that are usually nation-state or nation-state backed and usually stay undetected for an extended time in later stages of Cyber Kill Chain in defenders’ networks. Keywords: Valuation of cyber assets, vulnerability of cyber assets, node supervision, sophistication of an attack germ of cyber-attack, cyber defense, proactive cyber protection, Advanced Persistent Threat (APT) actors, Indication of Compromise (IOC), Tactics, Techniques and Procedures (TTPs).
