=============================
Industrial Control Systems are what we call specialized industrial computers that control critical infrastructure and process automation systems.
Examples of where industrial control systems are used in critical infrastructure include the power grid, water and wastewater management, transportation, and natural gas.
Process automation systems that use industrial control systems include nuclear power plants, oil refineries, steel mills, and most types of factories. Any time an industrial process is automated, an industrial control system is likely being used.
Because so much of modern life depends upon the convenience and safety afforded by industrial control systems, cybersecurity is of utmost importance for these systems.
With attacks on industrial control systems becoming more common every year, cybersecurity for industrial control systems is quickly becoming a necessary component for many organizations.
Malware such as Stuxnet, Industroyer, Triton, and Pipedream, to name a few, have been used to target ICS hardware specifically, with the intent of disrupting operations or destroying equipment.
While a ransomware attack on an IT system can cripple an organization, an attack on an OT system has the potential to not only hinder the operations of an organization, but to destroy equipment, disrupt critical infrastructure, and cause loss of life as well.
While there is some overlap between cybersecurity best practices for IT systems and OT systems, there are some special considerations for industrial control systems.
While IT systems are often managed using centralized management systems such as Active Directory, industrial control system components must usually be managed as standalone systems.
PLCs, HMIs, and other ICS components usually ship with a default username and password which are well-documented and easy for attackers to guess.
Special care must be taken to ensure that default credentials have been changed or removed for each component. The new credentials must then be securely stored in order to prevent an attacker from gaining access to them.
Another unique aspect of securing industrial control systems is that endpoint protection software and firewall software typically cannot be installed on these systems.
In addition to adequately defending your industrial assets, it is important to have an incident response plan in place to determine how you will respond to, and recover from a cyberattack, should one take place.
This will enable you to quickly and effectively respond to an event and minimize the impact of a cyberattack on your organization.
In the IT world, security updates are usually applied on a regular schedule to patch security vulnerabilities. In the OT world, patching is performed far less frequently, if ever.
If patches can be applied to ICS components, they should be tested in a development environment to ensure that the updates will not disrupt the production system.

Excellent content. We expect more vedio on ICS/OT cybersecurity.
Thank you!
Thank you for such kind of understandable video. Great job
Glad it was helpful! You're very welcome
Amazing cybersecurity for industrial control system...very helpful
Glad it was helpful!
Thanks a lot for this valuable content, Waiting for more detailed tutorials explaining practical application
Thank you very much, Mohamed! Glad to hear that
I support you and this topic of the video
Please make more videos on the concept of network Segregation, zones, conduits in ICS. Thank you
Thank you for your topic suggestion, I will happily go ahead and pass this on to our course developers. Thank you very much for sharing.
thank u so much for the quality ,
You're very welcome!
Another great video, thank you
Glad you enjoyed it, thank you very much!
Good stuff!
Are you guys planning on creating a Cybersecurity Series?
Greetings from Germany.
Thank you very much for your comment! Not in the near future, but I will happily go ahead and forward this to our course developers as a topic suggestion.
Thank you again for sharing, and happy learning :)
Well explained!
Thank you!
Great job, Make more video on cyber security.
Thanks for your comment, and for your feedback! Will happily forward this to our course developers.
Excellent video!
Thank you very much!
Well explained
Thank you very much, Maryam!
Very informative
Glad it was helpful!
great video
Glad you enjoyed it, thank you!
Excellent video with clear understanding .Sir what software is used for making presentation slides and animation. Is it power point?
Thank you very much! We're happy to hear that. Regarding your question, I am actually not entirely sure, as our video lessons are created by our animation and graphic department.
Your videos are amazing. Could you please upload videos about matlab tutorials
Thanks for your kind comment, and for sharing your topic suggestion! I will happily go ahead and forward this to our course developers.
Thank you again and happy learning!
Is it possible for a instrumentation engineer to work in industrial automation field?
Hi there,
Thank you for your question!
Of course, you can! You already have the instrumentation training or know-how, depending on your place of residency and standard requirement laws in your part of the world. We at RealPars offer courses in our Pro Membership to help you get started in this technical field or to enhance your current knowledge to the next level. Depending on where you are in your knowledge level, you can start with some of our free courses, which we have developed and working in progress, like Industrial Electrical Maintenance Essentials, Safety, Inspection & Repair, or some of our other courses. Here is the link to our course library, you can easily sign up over here as well

Happy learning!
Hi
What's Patching? And whats mitigation in this matter?
Thanks
Hello Genan Tamtam,
Thank you for your question :).
In the contents of our video, a patch is a set of changes or upgrades to an existing computer program or its supporting data designed to fix or improve a known or expected bug in the software. This includes fixing security vulnerabilities with such patches, usually called bugfixes or bug fixes. Patches are often written to improve the functionality, usability, or performance of a program. Most patches are provided by software vendors for operating system and application updates. For example, Microsoft updates the operating system on your computer. And the meaning in our video for mitigation is; cybersecurity risk mitigation is limiting the damage done by a security breach. It entails reducing the probability of a breach occurring and minimizing any damage caused.
Happy learning!
@@realpars thank you
Pls can you do a video on the lubrication system of a 4-stages CNG compressor 🙏
Thanks for your topic suggestion, Uche! I will happily go ahead and forward this to our course developers.
Thank you again for sharing, and happy learning!
