A manufacturing plant's control room houses the HMI servers and PLC programming stations. The room has a raised floor and a dedicated HVAC system. During a routine inspection, you notice that the fire suppression system is a water-based sprinkler system. What is the most appropriate change to make?

Install a smoke detector and rely on manual fire extinguishers

Add a backup generator to power the HVAC system

Keep the water sprinkler system but add plastic covers for the servers

Replace the water sprinkler system with a clean-agent gas suppression system

A company wants to integrate its physical access control system (PACS) with its logical access control for the SCADA network. The goal is to automatically disable a user's network account when their physical badge is revoked. What is the primary security benefit of this integration?

It eliminates the need for separate passwords for SCADA systems

It allows the security team to monitor employee keystrokes in the control room

It reduces the time window in which a terminated employee can access both physical and logical resources

It ensures that all employees use biometric authentication for both systems

Which of the following is an example of a physical security control used to deter unauthorized entry into an ICS facility?

A strong password policy for operator accounts

An intrusion detection system (IDS) monitoring network traffic

A perimeter fence around the facility

A firewall rule that blocks external access to the HMI

An engineering firm is designing a new building to house a SCADA development lab. The lab contains sensitive test equipment and prototype controllers. The design must minimize the risk of unauthorized visual observation from outside. Which facility design feature is most effective?

Use glass walls to allow natural light and open sightlines for staff

Place the lab on an upper floor with no windows facing public areas

Use tinted windows on the ground floor and rely on landscaping

Install a fence around the building but keep the lab on the ground floor

During a shift change, an operator notices that the door to the SCADA server room is ajar and the door frame appears damaged. The room contains the historian database and the domain controller. What is the FIRST step in the physical security incident response process?

Immediately reboot the server to ensure it is functioning normally

Check the server logs to see who logged in last

Secure the area and preserve the scene by not touching anything until law enforcement or security arrives

Call the IT help desk to request a new door lock
