ABSTRACT
This chapter first reviews communications operations, then the types of devices used in industrial communication networks, the various threats to networks, and then the various security measures available. Critical infrastructure (CI) includes any systems and assets that are so vital that their destruction or disruption threatens lives, governments, economies, ecologies, or the social/political structure of nations. To enable monitoring and control of CI systems, industrial control networks are often used. One type of Internet of Things (IoT) technology with increasing use in CI systems is the IEEE 802 standard subgroup. Physical attacks on CI systems can be seen in the form of terrorists and criminals who gain in-person access to a site to physically attack it. However, the expansion of IoT into CI systems, e.g., the Smart Grid, precludes the ability to successfully rely on security through obscurity for industrial control networks, and thus effective cyber security strategy is necessary.
