3.1.4 Security
Microsoft IIS with Microsoft Azure Virtual machine have been used to
host the system website. To login into the system, Captcha code is
required, which is demonstrated in figure 4. The Captcha code is created
by two methods, one for random code and the other for an image as a
background of the code. After each failed attempt the code should be
reentered again. This makes login into the system website more secure.
Session Object has been used to stay logged in in the system and pass
data between pages of the system [24] . The session object is stored
in the web server which makes the system safe. In terms of database
security, we have used SQL Parameter in MySQL Query to secure our
database against being destroyed.
