Security
 A major concern related to the design of web applications
 Many sites contain a huge quantity of personal and
financial information. Web sites being in the public
domain make them the target for hackers who want to
know your name and credit card details.
 It is therefore important to consider ways of protecting the
data in your site so that it reduces the risk of unauthorised
access.
 There are a number of measures that can be put in place to
improve security, some instantly obvious, others not so.
Create a Password System
Along with some facility for users to change their password (only
when they are logged in)
Also a way of re-sending forgotten passwords
