Which method do flight attendants use to ensure cabin security?

Monitoring activities and conducting regular checks is the most effective method for flight attendants to ensure cabin security. This proactive approach allows flight attendants to keep a close eye on the behavior of passengers and any potential security threats that may arise during the flight. By regularly walking through the cabin and observing the interactions and activities taking place, flight attendants can identify any unusual behavior or situations that may need further attention.

This method emphasizes vigilance and awareness, ensuring that flight attendants can respond quickly to any security concerns. It also fosters a sense of safety among passengers, as they see crew members actively engaged in maintaining a secure environment. In contrast, simply informing passengers about hazards or restricting movement entirely would not be practical or effective for overall cabin security. Reducing staff presence in certain areas would also not contribute positively to ensuring safety, as decreased monitoring could lead to vulnerabilities.
