What is secure remote access for OT systems enabled by Zscaler?
Secure remote access for OT systems enabled by Zscaler Private Access is a ZTNA service that takes a user- and application-centric approach to OT security.
Are remote access solutions putting your ICS and OT systems at risk?
With most remote access solutions, employees, contractors and third-party partners are granted full network access into the OT networks. In most cases, remote access solutions like VPN are putting the OT or ICS systems at risk by keeping access available 24/7 on the internet.
How to ensure the security of your OT systems?
Enable secure remote access to critical OT systems to maintain productivity and business continuity. The convergence of operational and information technologies can expose major security gaps. Cyberattacks have increased by 2000% as of 2019, yet only 23% of manufacturers are compliant with minimum-level ICS security guidelines.
How is ztna different from other remote access solutions?
While most remote access solutions based on the Purdue reference model for OT networks are network-centric, ZTNA focuses on providing secure connectivity between the user—employee, third-party partner, or contractor—and authorized enterprise applications, never the network.
What is OT in network security?
Operational technology (OT) is the use of hardware and software to monitor and control physical processes, devices, and infrastructure.
What is OT in IOT?
IT andOT. In an industrial environment IT and OT are often used, OT (Operational technology)refers to the hardware and software used to change, monitor, or control physical devices, processes, and events within a factory or production facility. Examples in the process industry are Scada, DCS and PLC systems.
What is the difference between IT and OT network?
IT systems are used for data-centric computing; OT systems monitor events, processes and devices, and make adjustments in enterprise and industrial operations.
What is OT and IOT security?
What is OT security? The purpose of OT security is to protect devices and networks in OT environments. It comprises technologies, organizational measures, and processes aimed at monitoring and protecting the availability and integrity of the systems. Its key objective is to ensure fault-free operation.

What is OT connected?
When it comes to physical devices, Operational Technology (OT) can be defined as a network connected device that monitors or controls processes and events outside of Information Technology (IT).
Is IoT and OT the same?
The Internet of Things (IoT) has changed the landscape of the energy industry. IP-enabled networks connect the operational technology (OT) side at the utility and the information technology (IT) side. This means a convergence between SCADA, AMI, DA and consumer engagement systems.
What is operational technology examples?
Examples include industrial control systems, building management systems, fire control systems, and physical access control mechanisms. The hardware, software, and firmware components of a system used to detect or cause changes in physical processes through the direct control and monitoring of physical devices.
What are the common challenges in OT Security?
What are the challenges for OT security?Lack of security awareness among OT staff.Lack of visibility into all of the OT systems on the manufacturing floor.Shared network infrastructure within the manufacturing floor between systems.Inability to address security issues by patching the OT systems.More items...
Why do we need OT security?
OT security is commonly used to protect Industrial Systems and networks from attacks. Operational technology security is used to protect and control critical infrastructures such as power stations, transportation networks and smart city appliances.
What is OT Security Engineer?
OT Security Engineer / OT Security Expert / OT Security Consultant. The OT Security Expert is responsible for the coordination of IT security measures related to OT systems, which includes development, implementation and improvement of central and de-central security measures related to OT.
What is OT industry?
Operational technology or OT is a category of computing and communication systems to manage, monitor and control industrial operations with a focus on the physical devices and processes they use.
What are OT assets?
An OT asset is a digital device that is part of an OT infrastructure. Devices can either be physical or virtualized. One can argue that there are other types of OT assets besides digital devices, such as software assets. From a theoretical perspective, that argument has its merits.
Access to operational technology (OT) systems is too broad
Many enterprises have fallen victim to security breaches due to attackers exploiting vulnerabilities of traditional VPNs and other appliance-based security solutions used to provide remote access to operational technology (OT) systems or Industrial Control Systems (ICS).
Vendors only need to access their specific ICS systems, so why introduce them to the OT network?
We know it’s risky to extend full and lateral OT network access to all users, but you need to provide them with access to their specific OT systems. The solution is to decouple OT systems management software access from the network, while segmenting access based on individual users and apps.
Eliminating remote access risk is easy with a zero trust network access (ZTNA) service
Secure remote access for OT systems enabled by Zscaler Private Access is a ZTNA service that takes a user- and application-centric approach to OT security.
Browser access enables secure third-party vendor access in minutes
With ZPA browser access service, third-party partners and users gain secure access to OT systems without the need for a client. Partners no longer need to jump through hoops to securely access OT systems—they simply use their own device to effortlessly access them over the internet.
