Detention differs from arrest in legal terms. Merchants and security personnel may temporarily detain someone suspected of theft under "shopkeeper's privilege" laws. This must be done with reasonable cause, for a reasonable period, and without excessive force. Arrest involves formal legal procedures and typically requires law enforcement authority.

Risk transfer refers to shifting the financial burden of potential losses from an organization to a third party, typically through insurance. By paying a premium, the company secures coverage that will compensate for specific losses, thereby reducing its own financial exposure.

Passive Infrared (PIR) sensors operate by detecting changes in infrared radiation (heat) levels in a given area.
They do not emit any energy but instead sense the movement of heat signatures (typically from people) across a background that has a stable infrared profile. When a warm object moves in front of the sensor, it registers a change and triggers an alert.
B and C describe active sensors (e.g., microwave or ultrasonic).
D refers to analyzing reflected infrared, which is not how PIR sensors function.

Organizational levels of terrorism are generally classified into:
Individual Terrorism (Lone-wolf actors)
Group Terrorism (Non-state groups like al-Qaeda, ISIS)
State Terrorism (When a state uses terror tactics on its own or others' populations) Modern terrorism refers more to the contemporary methods, tools, and global nature of terrorism-not a level of organization. Hence, it's not considered an "organizational level." References:

To identify and classify risk effectively, a security practitioner must understand:
Assets: What needs protection.
Exposure: What threats or vulnerabilities exist.
Losses: What the impact would be if threats materialize.
This foundational analysis guides the prioritization and mitigation of risk.
B, C, and D mix relevant terms but do not define the core framework for risk identification.
