Understanding OT protocols

Many supported protocols can be found in ICS and OT environments. Some protocols have been in existence for over 50 years and lack controls to encrypt data or provide integrity. Newer protocols have robust security built in. We will take a look at examples of these protocols.

Controller area network bus

This protocol was originally designed for the automobile industry, intended to minimize the amount of cabling deployed within a vehicle. It is able to allow devices on the bus to communicate within the requirement of a centralized host computer. The design is based upon multiplexing, where multiple signals can be transmitted on a single shared bus. In order to share the bus, each device can be assigned a priority. If two nodes transmit on the bus at the same time, then the highest-priority device will have precedence.

The controller area network (CAN) specification does not support any native security or encryption; it is intended as a specification...
