Q

When you follow someone through a secure door with that person’s consent you are:

A

Piggybacking

17
Q

When you follow someone through a secure door without that person knowing you are:

A

Tailgating

18
Q

___________________ help prevent from users Piggybacking or tailgating as normally there is just not enough room.

A

Access Control Vestibules

19
Q

these are also used with Access Control Vestibules as a last means of getting into the facility:

A

Access Badges

20
Q

Badges are often equipped embedded technologies

A

Radio-Frequency identification (RFID)
Near-Field communication (NFC)
Magnetic Strips

21
Q

These help with being a “Visual Deterrent”, provided Assistance, can check the visitors identity, also be a way of responding to all issues are known as :

A

Security Guards

22
Q

The following three create a multi-layer approach to increasing our physical security:

A

Access Control Vestibules
Access Badges
Security Guards

23
Q

What is the best way to keep people out of those offices that have sensitive information, a physical security control that is designed to secure entryways?

A

Door locks

24
Q

most common door lock that’s used is or has a:

A

Identification number style

25
Q

other types of locks include

A

biometric - physical characteristics something you are, fingerprint, eye retina
wireless

26
Q

What is the rate that the system authenticates a user as valid, even though that person should not have been granted access to the system?

A

False Acceptance Rate ( FAR )

27
Q

to prevent unauthorized people from entering the building, ideally you want to get that FAR down to __________ by increasing the sensitivity of the scanners.

A

zero

28
Q

What is it called when the biometrics system denies a user who should have been allowed access to the system

A

False Rejection Rate ( FRR )

29
Q

This uses a measure of the effectiveness of a given biometrics system to achieve a balance, also is called the Crossover Error Rate/the time when the FAR and the FRR meet.

A

Equal Error Rate ( EER )

30
Q

the __________ the crossover error rate, the better that lock

A

lower

31
Q

many of the modern _______ ________

A

will combine multiple authentication factors before giving access to something

32
Q

An old school _________ lock provides excellent protection using a mechanical locking mechanism with push buttons that are numbered

A

cipher

33
Q

these are popular technologies used for contactless authentication in various applications

A

Radio Frequency Identification ( RFID )
Near Field Communication ( NFC )

34
Q

What is one of the most prevalent vulnerabilities that you should be aware of Regarding RFID and NFC?

A

access badge cloning

35
Q

what are ways of cloning an access badge:

A

Scanning- using a hand held card reader to capture the data
Data Extraction:
Writing to a new card:
Using a cloned access badge

36
Q

______ _______ _________ is considered to be a stealthy way to conduct a physical security attack

A

Access Badge Cloning

37
Q

How to prevent Access Badge Cloning:

A
  • Implement advanced encryption in card-based
    authentication Systems
  • Implement Multi-Factor Authentication / pin, password
  • regularly update the security protocols
  • educate users to protect their badges at all times
  • Users should implement or use shielded wallets or sleeves
  • monitor and audit your access logs
