Physical security
| Question | Answer |
|---|---|
| physical security | Measures taken to protect tangible assets, like buildings, equipment, and people, from Harmer unauthorized access (security cameras) |
| bollards | short, sturdy vertical posts designed to control or prevent access by vehicles to an area or structure. Keep vehicles from building. physical barrier that shields pedestrians and structures. |
| Fence | structure that encloses an area using interconnected panels or posts |
| attacking with brute force | |
| surveillance system | organized strategy or setup designed to observe and report activities in a given area |
| access control vestibule | Double-door system with two electronically controlled doors that ensure only one door is open at any given moment |
| piggybacking | two people, with and without access, entering a secure area |
| tailgating | whenever an unauthorized person closely follows someone with access without their knowledge or consent |
| Doorlocks | padlocks, simple pin and tumbler, numeric, wireless, biometric , cipher, electronic access control systems |
| Fence purpose | provide visual deterrent by defining a boundary, establishes a physical barrier against unauthorized entry, delays intruders |
| brute force | Attack where access to a system is gained by trying all of the possibilities until breaking through |
| Forcible entry | Act of gaining unauthorized access to a space by physically, breaking or bypassing its barriers, such as windows, doors, or fences |
| Tampering with security devices | Involves manipulating security devices to create new vulnerabilities that can be exploited |
| Confronting security personnel | Involves a direct confrontation or attack of a security personnel |
| Ramming a barrier with a vehicle | brute force attack that uses a car, truck, or other motorized vehicle to ram into the organization of physical security barriers |
| Surveillance systems | Maintain the security and safety of facilities, including business, home, or commonly used public areas (security guards and security systems) |
| four categories of surveillance | video surveillance, security guards, lighting, sensors |
| what type of control are surveillance cameras? | wired version(wired to the building), wireless version (relies on wi-fi) CCTV. Indoor (withstand harsh conditions) and outdoor systems |
| Pan-Tilt-Zoom (PTZ) | can move the camera or its angle to better detect issues during an intrusion |
| common camera placements? | data center, telecommunications closets, entrance or exit areas |
| security guards | Flexible and adaptable forms of surveillance that organization issues use |
| lighting | proper lighting is crucial for conducting effective surveillance using both video and security guards |
| sensors | devices that detect and respond to external changes in the environment and convert the information into readable signals or data |
| infrared sensors | detect changes in infrared radiation that is emitted by warm bodies like humans or animals |
| pressure sensors | activate when a specified minimum amount of weight is detected on the sensor that is embedded into the floor or a mat |
| microwave sensors | Detect movement in an area by emitting microwave pulses and measuring their reflection of moving objects |
| ultrasonic sensors | Measure the reflection of ultrasonic waves off moving objects |
| visual obstruction | Walking to car line of sight(paint on camera, etc) |
| blind sensors and cameras | overwhelming the sensor or camera with a sudden burst of light to render it ineffective for a limited period of time |
| acoustic interference | jamming or playing loud music to disrupt the microphone's functionality (white noise machines, noise jamming devices) |
| electromagnetic interference (EMI) | Jamming the signals that surveillance systems rely on to monitor the enviornment |
| physical environment attack | Exploiting the environment around the surveillance equivalent to compromise his functionality |
| countermeasures to protect surveillance systems | tamper alarms, backup power supplies/UPS, encrypt frequencies |
| access control vestibule | Double-door system that is designed with two doors that are electronically controlled to ensure that only one door can be opened at a given time |
| piggybacking | Person with Legitimate Access intentionally allows another person without authorization to enter a secure area with them |
| door locks | Physical security control that is designed to secure entryways by restricting and regulating access to a particular space or property |
| False Acceptance Rate (FAR) | Rate that the system authenticates a user as valid, even though that person should not have been granted access to the system |
| equal error rate (EER) | Crossover error rate (CER), which uses a measure of the effectiveness of a given biometric system to achieve a balance |
| cypher lock | excellent protection using a mechanical looking mechanism with push buttons that are numbered and require a person to enter the correct combination in order to open that door |
| Radio frequency identification | contactless authentication in various applications |
| NFC | contactless authentication in various applications |
| Access Badge Cloning | copying the data from an RFID or NFC card or badge onto another card or device |
| How does an attacker clone that access badge? | scanning, data extraction, writing to a new card, using a cloned access badge |
| RFID Lock | electronic locking mechanism that uses Radio Frequency Identification technology to grant access. Card or key fob convenience and rapid access control, especially in environments requiring quick secure entry. |
| Cipher Lock | mechanical locking system that uses push buttons, often numbered, and requires the correct combination to be entered for access. |
| biometric lock | |
| PIN lock |
