CompTIA Security+ Certification SY0-601: The Total Course - Chapter 9 Exam Question Review

The video tutorial discusses industrial computing environments, focusing on ICS and PLC systems. It presents a scenario where an IT security technician must prevent unauthorized network access in a water treatment facility. The recommended solution is air gapping, which isolates the network from others, including the internet. While air gapping is effective, it has limitations, such as vulnerability to infected devices. Other security measures like MFA, network intrusion detection, and IPsec are also discussed, but air gapping remains the most effective for preventing remote access.
