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.

Is remote control the same as radio control?
So, essentially, remote-controlled vehicles are pretty much the same as radio-controlled vehicles. A radio system is necessary to operate any remote-controlled vehicle. Remote controls can be used to send radio signals to a matching receiver through a hand-held transmitter, placed on the remote control car.

What is difference between DCS and SCADA?
The main similarity between SCADA and DCS is that both systems control plant operations and the devices that they can deploy. On the other hand, the main difference is what they focus on - SCADA systems prioritize collecting and understanding data, while DCS systems is geared towards process control.
What is SCADA and OT?
OT is a term developed to differentiate it from IT, which represents the information technology assets of an organization. OT is closely related to ICS (industrial control systems) and SCADA (supervisory control and data acquisition systems). IoT - Internet Of Things.

What is remote access examples?
Accessing, writing to and reading from, files that are not local to a computer can be considered remote access. For example, storing and access files in the cloud grants remote access to a network that stores those files. Examples of include services such as Dropbox, Microsoft One Drive, and Google Drive.
What is required for remote access?
Remote computer access requires a reliable internet connection. You'll need to activate or install software on the device you want to access, as well as on the device — or devices — you want to use to get that access.
What is a best practice for compliance in the remote access domain?
Instead, a best practice is to adopt the principle of least privilege, which means that access for all users should be blocked by default and enabled only for the specific accounts that require it.
What are potential risks associated with remote access?

Basic Security Tips for Remote DesktopUse strong passwords. ... Use Two-factor authentication. ... Update your software. ... Restrict access using firewalls. ... Enable Network Level Authentication. ... Limit users who can log in using Remote Desktop. ... Set an account lockout policy.
Which protocol is used for encrypted remote access to a server?
IPsec. Internet Protocol security (IPsec) can be used as a remote access tunneling protocol to encrypt traffic going over the Internet.
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.
Preventing industrial control system attacks
In the US, the Cybersecurity and Infrastructure Security Agency (CISA) provides information designed to empower industry leaders to combat ICS oriented threats.
Why do external parties need to connect remotely to critical infrastructure control networks?
This access is to allow the manufacturers of equipment used in Australia’s critical infrastructure the ability to maintain the equipment, when a fault is experienced that cannot be fixed in the required timeframe any other method.
What is the Australian Government Information Security Manual?
The Australian Government Information Security Manual is a cyber security framework that organisations can apply to protect their systems and data from cyber threats. The advice in the Strategies to Mitigate Cyber Security Incidents, along with its Essential Eight, complements this framework.
What should be the default communication between the vendor and the critical infrastructure control system?
1. By default, there should be no communication between the vendor and the critical infrastructure control system.
Which end should authenticate the critical infrastructure organisation?
10. The remote end should authenticate the critical infrastructure organisation also, i.e. ‘mutual authentication’.
Why do external parties need to connect remotely?
External parties may need to connect remotely to critical infrastructure control networks. This is to allow manufacturers of equipment the ability to maintain the equipment when a fault is experienced that cannot be fixed in the required timeframe. Such access to external parties will only occur in extraordinary circumstances, ...
When must remote access data be returned?
Ensure contractually that any data viewed or acquired as part of the remote access is used only for the purpose of resolving the issue the remote access was granted for, and must be returned to the critical infrastructure organisation and destroyed at the remote access end either when the issue is resolved, or after the period of 1 year , whichever is sooner.
When should the connection between the control network and any external device be physically disconnected?
2. The connection between the control network and any external device should be physically disconnected when the protocol is not being used. Ideally this would mean removal of a physical cable, however sometimes the location to disconnect the cable may be a significant distance from the control equipment.
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.
