A particular web application operation accepts an image

upload. The logged in user provides a user ID, an image

name, a brief description and image preferred size (height

and width). Explain what checks the server-side function

should perform (in general terms, code is not needed)

before attempting to process the submission.

provide an example of activity logging that would require

additional security concerns to be addressed and why.

Explain a coding technique that can be used to protect

against Cross-Site Scripting vulnerabilities.

Explain a coding technique that can be used to protect

against SQL insertion.

Explain how the ViewState field or a CSRF token helps

protect against Cross-Site Request Forgery.

server side should check if some null constraints are

applied to any of these fields more over if image size is

already given to be uploaded, in case of failure of checking

server should prompt a general message for the related

every day.

as an example took the login with facebook, the facebook

must disable the functionality of browser of save password

because by doing so no outsider would enter your timeline.

Explain a coding technique that can be used to protect

against Cross-Site Scripting vulnerabilities.

1. Safely validating untrusted HTML input

2. Cookie security

3. Disabling scripts

Explain a coding technique that can be used to protect

against SQL insertion.

1. By doing Prepared Statements

The use of prepared statements with variable binding is

how all developers should first be taught how to write

database queries

2. Using Stored Procedures

3. Using White List Input Validation

4. Least Privilages

Explain how the ViewState field or a CSRF token helps

protect against Cross-Site Request Forgery.

The CSRF token is added as a hidden field for forms or

within the URL if the state changing operation occurs via a

GET.The server rejects the requested action if the CSRF
