Name one challenge unique to patch management in SCADA environments.

Downtime risk: Applying patches may require system restarts, which can disrupt continuous industrial processes.

intermediate

What is a common best practice before applying patches in SCADA systems?

Test patches in a controlled environment to ensure they do not disrupt operations before applying them to live systems.

How can automation help in patch management for SCADA?

Automation can schedule patch deployment during low-risk times and track patch status, reducing human error and downtime.

What is the main goal of patch management in SCADA systems?

A Remove all software updates

B Add new hardware components

C Fix security vulnerabilities and improve system reliability

D Increase system power consumption

Patch management aims to fix security issues and keep SCADA systems reliable.

Which of these is a risk when patching SCADA systems?

A System downtime affecting operations

B Improved system speed

C Automatic hardware upgrades

D Reduced security

Patching can cause downtime, which is risky for continuous SCADA operations.

Before applying patches to SCADA systems, what should be done?

A Ignore patch notes

B Apply patches directly to live systems

C Disable all security features

D Test patches in a safe environment

Testing patches first helps avoid unexpected problems in live systems.

How does automation improve patch management in SCADA?

A Removes all patches automatically

B Schedules patches and tracks status to reduce errors

C Increases manual work

D Disables system monitoring

Automation helps by scheduling and tracking patches efficiently.

Why must patch management be handled carefully in SCADA systems?

A Because SCADA controls critical infrastructure

B Because SCADA systems are not important

C Because patches are always harmful

D Because SCADA systems never need updates

SCADA systems control important infrastructure, so patching must be done carefully.
