Security Technology & Integration Flashcards

What does 'false positive' mean in the context of intrusion detection systems?

Answer: An alarm triggered by a non-threatening condition, such as an animal or wind movement

A false positive occurs when an IDS generates an alarm in the absence of an actual threat, such as from wildlife, weather, or equipment vibration.

Which standard is widely referenced for the installation and performance of electronic security systems in the US?

Answer: NFPA 731 (Standard for the Installation of Electronic Premises Security Systems)

NFPA 731 provides guidelines for the installation of electronic premises security systems, including intrusion, access control, and video surveillance components.

What is 'tailgating' in physical security and how does technology help prevent it?

Answer: An unauthorized person following an authorized person through a secured door; prevented by mantrap portals or anti-passback access control

Tailgating is when an unauthorized individual follows an authorized person through a secured entry; mantrap portals and anti-passback features in access control systems help prevent this.

What is the role of a PSIM (Physical Security Information Management) system?

Answer: To integrate data from multiple disparate security systems into a unified interface for real-time situational awareness

A PSIM integrates inputs from various security systems — cameras, alarms, access control — into a single interface, enhancing situational awareness and response coordination.

Which access control technology uses a unique biometric identifier that cannot be lost or stolen?

Answer: Fingerprint or iris scanner

Biometric systems like fingerprint or iris scanners authenticate based on unique physiological traits that cannot be lost, stolen, or shared like cards or PINs.

What is the primary security concern when integrating physical security systems with IP networks?

Answer: Exposure to cyber vulnerabilities such as unauthorized remote access or data interception

Connecting physical security devices to IP networks introduces cybersecurity risks, including unauthorized remote access, firmware exploits, and data interception.
