Over recent years we have witnessed how industrial controls systems are not exempt from being targeted for cyberattacks. In this article we look back at threats detected in recent years to see how we can defend ourselves against them.

The concept of defence in industrial environments is changing. Just as the attacks are increasingly more sophisticated, the protection systems tend to be more flexible and more evolved. Being able to strengthen the upper levels, such as active defence and intelligence, is essential, whilst always maintaining a solid base of the lower levels (passive defence and secure architecture).

Given that availability is always a critical point to take into account for within industrial environments, it is necessary to prevent the attacks that denial of services cause and that affect these environments. The means of giving way to a denial of service can be diverse, much like the means of mitigating these problems. This article will review all of these points, as well as the way in which the risks derived from these attacks can be reduced.

The wireless protocols used in industrial environments for communication between devices are numerous are extensive, therefore ensuring these communications is vital for industrial process to function correctly. In this article, we'll look at the advantages of wireless communication audits and the disadvantages of not performing them.

Not only is the interpretation of network traffic crucial to analyse the safety and performance of a network structure, but also for other tasks, such as incident management, the optimisation of our network infrastructure or for didactic purposes. In order to do so, it is necessary to have dissectors that help separate each of the fields that make up a protocol, and allow them to be individually analysed.

It is increasingly common to find malware related to cryptocurrencies, either to use them as payment currency in extortions and illegal activities, cryptocurrency theft or infiltrate on systems and equipment from all areas to take advantage of the resources of the victims' equipment to undermine cryptocurrency

The aim of Cybersecurity Highlights service is to gather all relevant news related to cybersecurity through the year. This is the article that summarizes those news that have been more important in 2017.

Denial-of-service attacks are a type of cyber-attack which consists on reducing or cancelling altogether the capacity of servers or other computing resources to provide service. A denial-of-service attack can occur in different scenarios, such as overloading online services by mass request sending or exploiting vulnerabilities of programs or services in order to suspend function totally or partially. In most of such attacks, attackers use a wide range of techniques and tools to hide their identities, which makes it especially challenging to find the culprits.

The Open Web Application Security Project (OWASP) has published the 10 most critical web application risks, 2017 edition, which points injection attacks as the greater security risk once again, as in the 2013 and 2010 editions.

The protection of critical and strategic infrastructures in our country is a task that must be tackled by all the agents involved in a public-private cooperation framework.

The IDS, IPS and SIEM are equipment originally designed for IT environments but whose adaptation to TO environments has been forced in recent years due to a proliferation of attacks on industrial environments.

After having analysed the "why" behind the cybersecurity capacities evaluation model in the first entry dedicated to the C4V model and after having explained how to carry out an appropriate management of risks in the value chain in the second edition, this third edition is dedicated to explaining how to carry out an evaluation of ourselves.
