Real-Time Operating Systems, hardening and functioning
ICS environments are made up of very heterogeneous machines, with large differences depending on the system we are dealing with. Some of these systems have very strict response time requirements for their correct operation and therefore use real-time operating systems.
Throughout this article we will see what real-time operating systems are, how they work, and we will propose hardening measures to reduce the likelihood that these devices will suffer a cyberattack.
