Integrating Networked Devices Flashcards
There are several different types of networks:
Personal Area Network ( PAN ) - Cell phones
Campus Area Network ( CAN ) - schools
Wireless Lan ( WLAN )
Local Area Network ( LAN ) - switches and computers ( no router )
Wide Area Network ( WAN ) - multiple LANs
Metropolitan Area Network ( MAN ) - buildings connected in the city
Internet
Intranet - Private
The _________ ___ ______ describes the huge variety of devices you can access and control via the internet, and devices that connect directly to Internet sources. aka: Garage door openers, house lights, camera
Internet of Things ( IOT )
keep all or your IOT’s ______________ which includes using a separate SSID, creating a long PSK ( passphrase), putting the device(s) on a separate VLAN, periodically updating firmware, and using access control lists ( ACL’s )
Hardening Techniques
Examples of VOIP are:
Skype, Google Talk, Unified Communication
Old school phone systems were called :
PBX
Unified Communication is able to do:
Collaborative Tools / Workflow
Presence Information
Video Conferencing / Real Time
Fax
Messaging
the Phone end or end user communication tool for Unified communication is called a :
UC Device
Key components of Unified communication are:
UC Device ( or phone / display )
UC Server
UC gateway ( or Medianet )
Real Time Transport Protocol ( RTP ) runs on UDP and uses these ports
5004 & 5005
Session Initiation Protocol ( SIP ) runs on TCP and uses ports:
5060 & 5061
International Telecommunication Unit ( ITU ) - H.323 ( a way to switch and control how different types of audio and video go over a network ) uses TCP and port:
1720
Media Gateway Control Protocol ( MGCP ), used with Medianets, runs on UDP/TCP, and uses ports:
2427 & 2727
computer that run machines in plants
Industrial Control Systems ( ICS )
Components of the ICS system are:
Machine
Controller or ICS server ( has sensors, actuators ) or Programmable Logical Controller ( PLC )
Interface ( where the operator talks to the system ) or HMI’s
An extension of ICS that utilize multiple stations is called:
Distributed Control Systems ( DCS )
