Section 4 Physical Security Flashcards
(17 cards)
What is Physical Security?
Measures taken to protect tangible assets such as buildings, equipment, and personnel from harm or unauthorized access
Physical security encompasses various strategies and tools to safeguard physical assets.
What is a Fence?
A structure that encloses an area using interconnected panels or posts
Fences serve as a physical barrier to deter unauthorized access.
What are Bollards?
Robust, short vertical posts designed to manage or redirect vehicle traffic
Bollards are often used to protect pedestrian areas from vehicle incursions.
Define Brute Force in security context.
Trying all possible options to gain access to a system until a breakthrough is achieved
This method can be time-consuming and is often used in hacking scenarios.
What is Forcible Entry?
The act of gaining unauthorized access to a space by physically breaking or bypassing its barriers (windows, doors, fences)
Forcible entry is a common tactic used by intruders.
What is a Surveillance System?
An organized strategy or setup designed to observe and report activities in a given area
Surveillance systems can include cameras, alarms, and monitoring software.
What is Visual Obstruction?
Blocking the camera’s line of sight
Visual obstructions can hinder the effectiveness of surveillance systems.
What are Blinding Sensors and Cameras?
Overwhelms sensor or camera with sudden burst of light to make it ineffective for a limited period of time
This technique can be used to temporarily disable surveillance.
Define Acoustic Interference.
Jamming or playing loud music to disrupt the microphone’s functionality
This can prevent audio surveillance from capturing clear sound.
What is Electromagnetic Interference (EMI)?
Jams signals or frequencies the surveillance system uses
EMI can disrupt communication between surveillance devices.
What is a Physical Environment Attack?
Exploits environment, ex. changing temperature of room for infrared sensors
This type of attack targets the physical conditions that sensors rely on.
What is an Access Control Vestibule?
Double-door system; doors are electronically controlled so that only one door can be opened at a time
This design helps prevent unauthorized access by controlling entry.
What is Piggybacking?
Person with legit access intentionally allows another person without authorization to enter a secure area with them - consent
This can pose a security risk if not monitored.
What is Tailgating?
Like piggybacking, but unintentional by the authorized person letting the unauthorized person in - nonconsent
Tailgating can occur in busy environments where access control is lax.
What are Door Locks?
Physical security control that is designed to secure entryways by restricting and regulating access to a particular space or property
Door locks are a fundamental aspect of physical security.
What is Access Badge Cloning?
Copying the data from a RFID/NFC card to badge onto another card or device
This can lead to unauthorized access if not properly controlled.
