Study Notes

DionTraining.com study notes discuss various methods of unauthorized personnel gaining access to secured areas, requiring physical security measures.
Establishing a physical barrier: bollards for countering vehicular threats, fencing for larger perimeters.
Brute Force attacks: gaining access by trying all possibilities, focus on Forcible Entry Act, use high-strength doors with deadbolts.
Tampering with security devices: manipulating devices to create new vulnerabilities, have redundancy in physical security measures.
Confronting security personnel: direct confrontation or attack, security personnel should undergo rigorous training.
Ramming barriers with vehicles: using cars or trucks to ram into barriers, install bollards or reinforced barriers.
Surveillance Systems: organized strategy for observing and reporting activities, includes video surveillance and sensors.
Video Surveillance: includes motion detection, night vision, and facial recognition, can be wired or wireless.
Pan-Tilt-Zoom (PTZ) System: can move camera to better detect issues during an intrusion.
Best places for cameras: data centers, telecommunications closets, entrance or exit areas.
Security Guards: flexible and adaptable forms of surveillance, help reassure staff and customers.
Lighting: crucial for effective surveillance, deters criminals, reduces shadows and hiding spots, enhances video recording quality.
Infrared Sensors: detect changes in infrared radiation, often emitted by warm bodies.
Pressure Sensors: activated when specified minimum weight is detected, embedded into floors or mats.
Microwave Sensors: detect movement in an area, emit microwave pulses and measure reflection off moving objects.
Ultrasonic Sensors: measure reflection of ultrasonic waves off moving objects.
Bypassing Surveillance Systems: methods used to bypass surveillance, such as visual obstruction, blinding sensors and cameras, interfering with acoustics, and electromagnetic interference.
Access Control Vestibules: double-door system designed to ensure only one door is open at a given time, can prevent piggybacking and tailgating.
Piggybacking: two people working together, one with legitimate access allowing unauthorized person to enter a secure area.
Tailgating: unauthorized person closely follows someone with legitimate access into a secured area.
