MAY/JUNE 2010 Scenario 1
Scenario 1 – Question 1a
Scenario• A large international airport is required to
introduce a number of security measures and has introduced new customer information services.
Question 1a:• State three items of information that would
be stored on the passport. [3]
Answers for Question 1aAny three points from:• Passport type• Country of issue• Nationality• Passport number• Entry and exit stamps
with dates/ countries visited• Photograph• Name of passport
holder
• Date of birth• Place of birth• Occupation• Issuing office• Holder’s signature• Gender• Date of issue/expiry• Any visa associated with
passport• Additional security
information/biometric data
Examiners report for question 1a
• This section concerns the three items of information on a passport.• There were 14 possible answers to obtain marks and
candidates usually understood which ones were sensible. Centres should emphasise that criminal records are not stored on a passport- a separate, secure database is used with the passport number as the key field. Ethnic group is also not recorded on most passports and was not accepted. Addresses are not used as they can change from time to time.
Scenario 1 – Question 1bScenario:• All passengers will need to have an electronic
passport. The airport will use additional identification in the form of electronic fingerprinting at various points in the airport.• Tickets for all flights are now electronic (e-
tickets).Question 1b:• Describe the electronic components in the
passport. [2]
Answers for Question 1b
Any two points from:• embedded chip in one of the passport pages/
similar in concept to a smart card holding biometric and other data• Use of embedded “ring circuit”/RFID for
communication
Examiners report for question 1b
• This question caused some confusion. The Examiners were looking for electronic elements in a passport. These were RFID and a chip. Very few candidates gave these 2 answers- the key word being electronic. Too many answers were about barcodes, magnetic stripes and even MICR. A magnetic stripe does not hold biometric details. A bar code holds just an ID number and check digit yet they were given as holding biometric details.
Scenario 1 – Question 1cScenario:• All passengers will need to have an electronic
passport. • There are computer-based information kiosks
throughout the airport. Passengers can now print out their own boarding passes and obtain flight information from any one of these kiosks.
Question 1c:• (c) Describe three advantages of electronic
passports when compared to paper-based passports. [3]
Answers for Question 1cAny three points from:• Information on the chip is quicker to read by computer• Easier to update from a computer• More information can be stored on the electronic
passports• More difficult to “tamper” with the information• More difficult to produce illegal/non-authorised/forged
passports• Difficult for somebody to use the wrong/stolen passport• Remote processing of passport (using RFID)• Could be a smart card/smaller …• … Description of facial/iris recognition system
Examiners report for question 1c
• This question was about the advantages of electronic passports over paper based ones. • Too many candidates did not understand that
an electronic passport is a physical device with electronic elements- it is not a soft copy held in a database.
Scenario 1 – Question 1dScenario:• A large international airport is required to
introduce a number of security measures and has introduced new customer information services.• The airport will use additional identification
in the form of electronic fingerprinting at various points in the airport.
Question 1d:• Explain how the use of electronic
fingerprinting improves airport security. [4]
Answers for Question 1dAny four points from:• Take fingerprints on non-air side of airport• Restricting access to secure areas for staff/passengers• Re-take fingerprints on boarding side• Fingerprints are stored electronically and can be accessed at any
terminal• It is possible to store the fingerprints electronically on passport• Very difficult to forge a finger print/ fingerprints provide greater
security• System check if 2 sets of fingerprints match up• Compares fingerprints with pre-stored values on security
database/passport• Computer database can match fingerprint to a suspect if passport
false• Computer database can match fingerprint to known criminal• Audit trail of employee movements
Examiners report for question 1d
• The use of fingerprints to control and monitor access around an airport was badly understood. The 7 marking points offer guidance about the level of detail required to earn marks in this question that relied on common sense as much as subject knowledge.
Scenario 1 – Question 2aScenario:• Tickets for all flights are now electronic (e-
tickets).• There are computer-based information kiosks
throughout the airport. Passengers can now print out their own boarding passes and obtain flight information from any one of these kiosks.
Question 2a:• Describe how the system will match an e-ticket
to a passenger when they check in at the airport. [3]
Answers for Question 2aAny three points from:• Lead passenger will have paid by credit card
number and has to give passport number…• - … name matched up with credit card holder
and/or passport• Ticket details emailed to lead passenger• Email printout used as confirmation• Email contains a unique (bar) code which
identifies passenger• Check-in details match up with stored passenger
details
Examiners report for question 2a
• There were 5 marking points for the 3 marks and most candidates scored 2. The barcode on an e-ticket is simply an ID number- it may be derived from passport number and/or credit card number.• It does not hold any large volume of data as
some candidates suggested in their answers.
Scenario 1 – Question 2b
Scenario:• Tickets for all flights are now electronic (e-
tickets).
Question 2b:• Describe the advantages of e-tickets when
compared to paper-based tickets. [3]
Answers for Question 2bAny three points both for passenger and airline from:• Reduces booking expenses for
airline• No need to print out tickets• No need for postage or envelopes• Saving on staff and
accommodation costs• Passenger feels more in control
by selecting seats in advance• More convenient/easily re-
printed• Can’t be lost/stolen/misplaced• Less prone to fraud• Passenger can print out own
ticket, no waiting for delivery
• Speeds up check-in at airport benefits passengers and airline/cuts down queues
• Easier for passenger to buy tickets (i.e. online bookings/no need to go to travel agent)
• System remembers customer details
• From history• From membership number• Simpler for passengers at airport;
only need a form of id
Examiners report for question 2b
• This was a question where candidates scored marks as they found it an easy question to understand.
Scenario 1 – Question 3a
Scenario:• There are computer-based information kiosks
throughout the airport. Passengers can now print out their own boarding passes and obtain flight information from any one of these kiosks.
Question 3a:• Explain the advantages to the passengers of
having computer-controlled information kiosks rather than manned desks. [3]
Answers for Question 3aAny three points from:• - no long queues at desks• - can be more terminals than desks• - Kiosks not under time pressure (unlike check-in staff)• - Kiosk available 24/7 and not affected by staff taking breaks• - no language problems/multi-language• - no interpersonal arguments• - passengers don’t mind dealing with trivial/ embarrassing questions• - terminal may be easier for passengers with communication
difficulties• - more information generally available• - information more likely to be up to date/less inaccurate• - faster processing at check-in desk as fewer questions to be discussed
Examiners report for question 3• This was an easy question for those candidates who had
used an e-ticket kiosk. Those who had not experienced a kiosk were not at a disadvantage, as they use standard ICT features. Most scored well on this question. Interesting how many answers were given about users not having an argument with a kiosk unlike human desk clerks.
Examiners report for question 3a• This section covered the advantages and was well
answered. Candidates must note for whom the advantages are applicable- in this case it is the passenger not the company.
Scenario 1 – Question 3bScenario:• There are computer-based information kiosks
throughout the airport. Passengers can now print out their own boarding passes and obtain flight information from any one of these kiosks.
Question 3b:• Discuss the security risks to the system arising
from the introduction of electronic information kiosks. [6]
Answers for Question 3bAny six points discussing the risks from:• NOT what a hacker can do.• Hackers/fraudsters might gain
access to database/server• Use of firewalls• Physical guards• Sensitive data travels to and from
the kiosks• Encrypt the data to make it
meaningless• Authentication techniques e.g. user
ids/ passwords• Levels of access• Need to log out• Digital certification• Need for security if kiosks use Wi-Fi
• People can overlook passengers typing in personal data
• Viruses sent to the system if external data link in kiosk
• Anti-virus software which is updated regularly
• Prevent customers being allowed access to memory devices
• Use of firewalls• Spyware giving access to system
which can look for security information on the system
• Use of anti-spyware software• Use separate systems for
customer information and security
Examiners report for question 3b
• This section was not well answered unlike the previous section. Candidates immediately thought of hacking. In real life this would only happen if the terminals used Wi-Fi to link to the server. The use of other devices is unlikely- apart from skimmers. The kiosks are dedicated to only provide services for e-tickets. They may well not allow www access as many candidates thought and then went on to give generic answers to security from surfing.
