Comparing Physical Security Controls Flashcards
List the 6 different boundaries you would implement physical security controls at
1) Perimeter
2) Building entrances
3) Secure work areas
4) Server and network rooms
5) Hardware itself
6) Airgap
Is a sign an example of a physical security control?
Yes
Cypher lock codes can be given out by uneducated users to unauthorized people. What other way might the code be obtained?
What can reduce these weaknesses?
Shoulder surfing
User security training
What’s the different between a proximity card and a smart card?
Smart cards you have to insert into the read, proximity cards can be held near the receiving device. Some smart cards also have proximity capabilities
Door access include cipher locks, proximity cards and..
biometric
Can proximity cards identify and also authenticate?
Yes, when combined with a PIN
Deploying security guards to increase security can have the following benefits:
Checking xxx prior to entry
checking people’s identity against a xxxx
reducing tailgaiting by xxx
1) checking badges
2) checking identity against a pre-approved ACL
3) by observing when they use their proximity cards
What physical security method provides the most reliable proof of a person’s location?
video surveillance
3 security implications to do with cameras are…
1) only record in xxx places
2) xxxx employees of the surveillance
3) do not record xxxx
1) only record in public places
2) notify employees of the surveillance
3) do not record audio
How might you stop unauthorized personel from escaping after providing false credentials at a perimeter?
install dual gates
What process can reduce the below vulnerabilities:
1) architecture and design weaknesses
2) system sprawl
Asset Management
How does asset management reduce architecture and design weakness?
because purchases go through an approval process it ensures they fit in the overall network architecture. Unapproved assets weaken security because they’re not managed
the cooling capacity of HVAC systems are measured in…
tonnage
1 ton of cooling equals
12,000 British Thermal Units/per hour
Name two ways HVAC systems control oxygen in the event of fire.
1) through the use of dampers that control airflow to specific areas
2) automatically turning off
both are triggered by the fire alarm system
