Question 41

Show Answer

The correct answer is B.

OBJ-3.3: Industrial control system (ICS) and supervisory control and data acquisition (SCADA) systems were developed many years before security standards were established and integrated into their design. Many of these older systems date back to the 1970s and are still in use today. Over time, these systems were incorporated into the organization’s TCP/IP data networks, which provides a huge exploitation area by penetration testers and attackers alike. Many ICS and SCADA vendors are slow to implement security measures since they cannot be easily retrofitted with the newer security required. Therefore, ICS and SCADA systems should ALWAYS be isolated from production networks and segmented into their logical network. For example, some ICS/SCADA systems use a proprietary operating system. More modern ICS/SCADA operates using a version of Windows. However, many still use Windows XP, making them much more vulnerable since they cannot be upgraded to Windows 10 without hardware replacement.
