CSC Security Technology in Courthouses 3 ā Questions and Answers
Question 1: Which document scanning technology allows courthouse security staff to quickly verify that a presented ID has not been altered or forged?
- Ultraviolet (UV) and infrared document scanners (Correct answer)
- Standard flatbed optical scanners
- Near-field communication (NFC) readers only
- Barcode label printers
Correct answer: Ultraviolet (UV) and infrared document scanners
UV and infrared scanners reveal security features embedded in legitimate IDsāsuch as fluorescent inks and hologramsāthat are absent or incorrect on counterfeit documents.
Question 2: An explosive trace detection (ETD) device at a courthouse checkpoint produces a positive alarm. The recommended immediate response is to:
- Confiscate the item and allow the individual to proceed
- Isolate the individual, call for supervisor and explosive ordnance disposal support (Correct answer)
- Re-run the sample a second time and clear the person if negative
- Record the alarm in the log and continue screening other visitors
Correct answer: Isolate the individual, call for supervisor and explosive ordnance disposal support
Any confirmed ETD positive requires treating the situation as a potential explosive threat: isolating the individual, notifying supervisors, and contacting EOD before taking further action.
Question 3: In courthouse video surveillance design, the term 'field of view overlap' refers to:
- The portion of screen real estate shared between two monitors
- Adjacent camera coverage areas that eliminate blind spots between cameras (Correct answer)
- The pixel resolution shared between a primary and backup camera
- A legal requirement to record footage from both inside and outside a courtroom
Correct answer: Adjacent camera coverage areas that eliminate blind spots between cameras
Overlapping fields of view ensure that movement can be tracked continuously between camera zones and that no unmonitored gaps exist in the surveillance coverage.
Question 4: A courthouse electronic access control system uses 'role-based access control' (RBAC). This means:
- Access is granted based on the time of day the credential is presented
- Permissions are assigned to job roles rather than to individual users (Correct answer)
- The system requires two separate credentials from the same person
- Access logs are reviewed by an external auditor after each entry
Correct answer: Permissions are assigned to job roles rather than to individual users
RBAC assigns access rights to defined roles (e.g., judge, clerk, security officer), so all users assigned that role inherit the same permissions, simplifying management.
Question 5: Which network security practice is most critical for protecting courthouse security systems (cameras, access control) from cyber intrusion?
- Connecting security devices to the public internet for remote access
- Network segmentation that isolates security systems on a dedicated VLAN (Correct answer)
- Using shared passwords across all security devices for easy management
- Disabling firewalls to avoid latency in video transmission
Correct answer: Network segmentation that isolates security systems on a dedicated VLAN
Placing security systems on a dedicated, isolated VLAN prevents attackers who breach the general courthouse network from reaching or manipulating security infrastructure.
Question 6: A courthouse uses biometric hand-geometry readers for access to the evidence storage room. Hand-geometry readers authenticate users by measuring:
- Fingerprint ridge patterns on all five fingers simultaneously
- The three-dimensional shape, length, and width of the hand and fingers (Correct answer)
- Vein patterns beneath the surface of the palm
- Skin conductance and temperature of the palm
Correct answer: The three-dimensional shape, length, and width of the hand and fingers
Hand-geometry readers capture the three-dimensional shape of the hand including finger length, width, and thickness to create a unique geometric template for authentication.
Question 7: A gunshot detection system (GDS) installed in a courthouse parking structure uses which primary sensing method?
- Seismic vibration sensors in the flooring
- Acoustic sensors that triangulate the sound signature of a firearm discharge (Correct answer)
- Infrared sensors that detect the muzzle flash of a weapon
- Chemical sensors that identify gunshot residue in the air
Correct answer: Acoustic sensors that triangulate the sound signature of a firearm discharge
Acoustic gunshot detection systems use multiple microphones to capture, classify, and triangulate the distinctive sound signature of a gunshot to determine location within seconds.
