IDSs are passive elements that are in our network to ensure its security, but what would happen if all our communications were encrypted, or would this protection measure be enough to ensure that my network is protected? These questions and more will be discussed in the following article to provide solutions and advice focused on industrial environments.
Demilitarized zones, also known as DMZs (demilitarized zones), are used for the secure exchange of information between computers on a network that we want to protect and an external network that needs to access those computers. DMZs are widely used in the IT sector and also in the OT sector, but the equipment and services they host are not exactly the same.
Honeypots and their implementation in a network, known as a honeynet, are a powerful tool for defending your system and safely monitoring the attacks carried out against it. In this article we will detail what honeypots are, their implementation in OT environments, the advantages and disadvantages of their implementation in the system and the latest honeypots developed for industrial control systems.
The increasing number of attacks to industrial networks forces us to analyse their behaviour so that we can implement measures to mitigate said attacks. One of the options used to learn about the behaviour of attacks is the deployment of honeypots. This article deals with the advantages and challenges of this technology when used in industrial environments.
