How does a remote control system work?
The process works something like this:
- You push the "volume up" button on your remote control, causing it to touch the contact beneath it and complete the "volume up" circuit on the circuit board. ...
- The integrated circuit sends the binary "volume up" command to the LED at the front of the remote.
- The LED sends out a series of light pulses that corresponds to the binary "volume up" command.

Remote controls can be used to send radio signals to a matching receiver through a hand-held transmitter, placed on the remote control car.
How does remote access work?
Remote access simply works by linking the remote user to the host computer over the internet. It does not require any additional hardware to do so. Instead, it requires remote access software to be downloaded and installed on both the local and remote computers.

EXECUTIVE SUMMARY
We rely on industrial control systems to sustain our lives; from utilities to manufacturing, to distribution, to water management. In the past decade, the connectivity level of industrial control systems has increased. In parallel with these digital transformations, ensuring the safety and integrity of these environments is imperative.
Industrial control system security: Notable vulnerabilities
1. Connectivity and integration with external platforms and third party systems provide opportunities for backdoor access and malicious activities.

What is IoT infrastructure?
IoT infrastructures interconnect building equipment with centrally monitored and controlled systems. Buildings are often maintained by many different service providers and using varying types of equipment for HVAC, lighting, elevators, etc. This presents a high–risk vulnerability to cybersecurity attacks. The Secomea Industrial Remote Access Solution provides an industrial IoT platform that secures on-demand remote access to selected equipment, and also secure tunneling to static surveillance using control protocols such as BACnet. You can easily manage who has remote access to which equipment in the building via drag-and-drop user access management.

Option 1: Hosted VPN
Hosted VPNs provide a secure connection with simple setup and network configuration. Typical hosted VPN solutions include a VPN router, a hosted VPN server, a VPN client, and connected automation system components (figure 2).
Hosted VPN design considerations
Those considering this solution must have a high level of trust in the hosted VPN vendor, as it will be responsible for securely storing data and making it available to only those who need it. Monthly costs incurred for high data bandwidth usage must also be considered, particularly as those costs are zero for a traditional VPN solution.
Option 2: Traditional VPN
This option requires a local VPN router to connect through the Internet with a secure VPN tunnel to a second remote VPN router or software client (figure 5). Once connected, remote users can access automation components connected to the local router through the VPN tunnel.
Traditional VPN design considerations
The main design consideration for this option is the capability and willingness of an IT team to support this solution at both the local and remote sites for each installation.
Application example: Traditional VPN
Consider two types of OEM machine builders. The first OEM sells very large and complex printing presses with thousands of automation system I/O points, and its customers require the OEM to support the machine, including uptime and throughput guarantees.
Application example: Hosted VPN
The second OEM sells a machine that does not require video monitoring. Local operator interface is provided by an embedded HMI with limited data logging and storage functionality. The OEM machine builder needs two kinds of remote access. The first is VPN access to remotely troubleshoot, debug, and program the machine’s PLC and HMI.
Many considerations
When designing a remote access solution using VPNs, there are many considerations influencing final implementation: initial and sustaining costs, technical expertise during installation and ongoing operation, site control, security risks, and data storage capabilities.
