I have created an on-line airline booking system that is able to take
customer flight information and customer details.  The system is also
able to generate e-tickets that gives each customer a unique reference
number to be used as a confirmation number of their flight and
booking.
I would like some help writing a report based on this industry with a
report examining and evaluating the key theoretical issues on the
security aspects of an online airline booking system.  I would need
any relevent information that would be produced in the form of a
report.

Here is a previous answer that may help:
