Virtualization is a technology that sooner or later will settle in the control systems, as was the case with corporate systems. The moment the impact that it may cause on the process is minimum and a proper security level may be guaranteed, it will be time to implement the virtualization of control systems.

Last year ransomware became the threat most widely used by attackers to monetise their actions. This fact has also affected industrial sectors which, to a greater or lesser extent, have suffered this type of malware.
The year 2016 has come to an end and once again we have witnessed an increase in the number of vulnerabilities published affecting control systems. Fortunately, companies are making greater efforts to prevent attacks and mitigate risks. The scenario for 2017 is similar to that of the past year.
In the same way that a known character or image is reflected within an industry by feigning a happy face, advanced persistent threats exist and are often camouflaged through the phenomenon of pareidolia (they resemble something else) within industrial networks. But how can we spot these threats? And, above all, is it possible to pre-empt their malicious intentions?
The process of fulfilling an attack implies many previous stages before arriving to the visible stage of the attack, that is, to the moment when the security of a system, company or industry is compromised. The cyber kill chain describes all those previous stages and establishes preventive actions for each of them.
The well known motto "there is strength in numbers" perfectly describes the beneficial situation that involves collaboration and knowledge sharing on cyber threats. The concept of Information Sharing bring to us the idea of establishing methods to share and take full benefit of the gathered knowledge among all actors. Among these partners, CERT and security companies play a key role in defining consensus documentation and the pathway for sharing knowledge effectively.
