To establish control in an industrial environment, it is first necessary to define and document what the normal traffic profile for a given system will be and what features will provide a real-time response to any behavior that deviates from the normal. Fortunately, the behavior of devices in an industrial environment is by nature quite static and predictable, so abnormal situations are likely to be detected quickly.
, there is traditionally a high level of trust in both people and devices. This explains why in many industrial networks, engineers can have full control of any PLC on the network from their laptops. It is not uncommon for full access to systems for maintenance purposes (via wired or wireless access) to be provided via uncontrolled laptops.
Protecting industrial environments requires a mandatory italy whatsapp data from a priori trust to a zero-trust model. What was once considered secure is now replaced by interconnected vulnerable systems and devices that can be compromised remotely.
It is useful to start information security with the assumption that the system being protected has already been compromised. Visualizing the presence of malware, unrestricted access, and the ability of a threat actor to escalate privileges allows information security teams to take a proactive approach to identifying and neutralizing access to critical and high-value assets. This approach also allows for the establishment of processes to quickly recognize behavior that is out of the ordinary.
