The Internet of Things (IoT) is a general term for the/a distributed network of devices typically used for the sensing and analysis of the physical world. IoT devices include smart home appliances such as personal assistants (including Amazon Echo and Google Home), “smart light bulbs,” “smart thermostats” and “smart meters.”
A subset of IoT is Industrial IoT, or IIoT, which is IoT for industrial sectors.
IIoT stands for Industrial Internet of Things, it is a flavour of IoT for the specific requirements of industrial sectors. Typically IIoT is used for the analysis of operational efficiencies and equipment maintenance, although it can also include all aspects of digitalisation of production lines.
The Institution of Engineering and Technology, or IET, is a society for people involved in electrical engineering, electronic engineering, computing or general technology. The IET has special interest groups focused on particular subjects, including Cyber Security and Control & Automation communities.
IACS is the acronym for Industrial Automation Control System. The term is in use internationally, and especially in Europe. It is a type of Operational Technology (OT) for the automation and control of industrial systems, such as those found in energy, water, transportation and manufacturing.
IACS is generally a synonym to ICS.
The acronym HMI stands for Human-Machine Interface which is an Operational Technology (OT). HMIs can be as simple as buttons and dials, or more complex such as touchscreen devices capable of processing.
Honeypot (also known as honeynet) is a system developed to attract attackers. Honeypots are useful to find out how a cyber attack on a particular system might occur, without/before exposing a real system.
Organisations deploying honeypots and honeynets should ensure that they are deployed and managed according to regulation and best practice within the countries that they are running.
