CS507 Assignment 4 Solution


QUESTION NO 1
What are the challenges faced by WAFs (Web Application Firewalls) in order to secure the web applications? Write only five challenges.

Solution:

The five challenges faced by WAFs (Web Application Firewalls) in order to secure the web applications are under below.

  1.  Application firewall needs to be able to apply exact, focused mitigation rules needs to be able to handle potentially thousands of such rules and needs to rapidly authenticate mitigation and report the full process.
  2. Automatic expose recognition alone cannot effectively recognize concerns with convention applications or exclusive business reason.
  3. The entire solution involves both vulnerability recognition and application firewalls. Evaluation needs to recognize rapidly confirmed vulnerabilities, extremely low false optimistic ratio.
  4. Vulnerability scanners alone cannot give web application safety measures. They can only give you insight into the specific concerns you have to fix.
  5. Application firewalls alone cannot offer web application defense. They cannot give guarantee that you have blocked all vulnerabilities or that no vulnerabilities exist. Manual configuration takes important amounts of time and need competent security analyst to do properly.
