Validating a password protection system
Authentication in the context of web applications is commonly performed by submitting a user name or ID and one or more items of private information that only a given user should know.Session Management is a process by which a server maintains the state of an entity interacting with it.A key concern when using passwords for authentication is password strength.A "strong" password policy makes it difficult or even improbable for one to guess the password through either manual or automated means.Failure to utilize TLS or other strong transport for authenticated pages after login enables an attacker to view the unencrypted session ID and compromise the user's authenticated session.In order to mitigate CSRF and session hijacking, it's important to require the current credentials for an account before updating sensitive account information such as the user's password, user's email, or before sensitive transactions, such as shipping a purchase to a new address.

The password change mechanism should require a minimum level of complexity that makes sense for the application and its user population.
For example: It is common for an application to have a mechanism that provides a means for a user to gain access to their account in the event they forget their password.
The initial login page, referred to as the "login landing page", must be served over TLS or other strong transport.
Failure to utilize TLS or other strong transport for the login landing page allows an attacker to modify the login form action, causing the user's credentials to be posted to an arbitrary location.
