CompTIA Security+ Certification SY0-601: The Total Course - Industrial Control System (ICS)

The video tutorial provides an in-depth look at industrial control systems (ICS), focusing on programmable logic controllers (PLCs) and their applications in various industries. It highlights the security challenges associated with PLCs, emphasizing the need for firmware updates and network isolation. The tutorial also introduces real-time operating systems (RTOS) used in PLCs and discusses the role of supervisory control and data acquisition (SCADA) systems in managing dispersed industrial environments. Key security incidents, such as the Stuxnet worm, are used to illustrate potential vulnerabilities.

What is a primary security concern with PLCs being networked devices?

• They can be potential attack vectors.

• They are expensive to maintain.

• They can be easily replaced.

• They require constant power supply.

Why is it important to secure the monitoring stations connected to PLCs?

• They are more expensive than PLCs.

• They can be vulnerable to malware, affecting PLC readings.

• They can be used to control the PLCs remotely.

• They are not connected to the internet.

What type of operating systems are typically used in PLCs?

• MacOS

• Android

• Windows

• Real-time operating systems

What is the purpose of network isolation for PLCs?

• To allow remote updates.

• To increase data processing speed.

• To prevent unauthorized internet access.

• To reduce power consumption.

What does SCADA stand for?

• Supervisory Control and Data Acquisition

• Systematic Control and Data Analysis

• Secure Control and Data Access

• Standard Control and Data Application

How can SCADA systems be geographically dispersed?

• Through local area networks

• By using wide area networks

• Via satellite connections

• Using Bluetooth technology

What is the role of a SCADA master station?

• To retrieve statistics from multiple PLCs

• To provide power to PLCs

• To update firmware on PLCs

• To manufacture industrial equipment
