Authentication:
The process where the user who is trying to gain access is being verified before getting the access. This is done by asking for user to enter his/her credentials by entering username/ user ID and password.
Authentication Bypass:
Trying to fool the system and bypassing the authentication process by not entering the right credentials is called authentication bypass. Or in other words having a loop hole in the application which allows a user to access application resources without being authenticated is called authentication bypass.
Server Side:
It is where the webserver and application logic reside. All critical operations like authentication, authorization, and data validation should be handled here to ensure security.
Client Side:
It refers to the actions performed on the user’s computer or browser. This includes input validation, form submissions, and displaying data.
Authentication bypass is a result of improper authentication mechanism followed for application resources. Unauthenticated access to critical content could result to improper access control and session management or improper input validation (SQL Injection).
Ways through which authentication bypass could be prevented are:
