ICS Topology, Mediums, Interconnectivity Flashcards
What are 6 types of Communications Media used today?
Licensed Radio Spread Spectrum Radio Cellular Land Line Microwave Satellite
This Comm Media uses VHF & UHF and would cost around $60-$460 to license and can “talk” farther than Spread Spectrum Radios.
Licensed Radios
A technology developed by the U.S. military 50 years ago where the basic operation is to spread data across a wide frequency band and reduce the impact of interference to the transmission rather than utilizing a specific narrow band channel.
Spread Spectrum Radio
Some of the Advantages & Disadvantages of this technology are:
Infrastructure is already in place and maintained by provider
Technicians can access services with personal devices
Network maintained by carrier
Possible Latency Issues At the mercy of service provided in case of reduced connectivity or outages Upfront cost of hardware Reoccurring monthly costs Limited coverage in certain areas Call drop problems
Cellular
This medium can be copper, coaxial, or fiber. This is a stand alone medium, quite capable of taking care of taking care of all your data needs, though using it conjunction with other mediums like radio is probably a more realistic approach simply because of the location of remote sites in relation to actual land lines.
Land Line
This type of technology uses point to point communications because their small wavelength allows conveniently-sized antennas to direct them in narrow beams, which can be directed at the receiving antenna.
Micro-Wave
This type of communications technology offers the ability to communicate to remote sites that may have been unreachable in the past with other mediums, at the cost of installing dishes at each remote site. This type of communications are sold through data plans.
Satellite
This communication platform ability allow two devices to communicate with each other using the same properties.
Protocols
What six areas are protocols broken into?
Process Automation Industrial Control System Building Automation Power System Automation Automatic Meter Reading Automobile/Vehicle
What several factors currently contribute to the increasing risk to control systems?
Adoption of standardized protocols and technologies with known vulnerabilities
Connectivity of the control systems to other networks
Insecure and rogue connections
Widespread availability of technical information about control systems
