When we say that authentication is “broken”, we mean that it is not possible to be certain that requests being made by a user with a certain claimed identity are in fact being made by the user with that identity.

There are many different scenarios in which access control may be broken (which we look into in more detail within) but in general an access control failure is any misconfiguration or flaw within the application such that records or resources are not properly protected as designed in terms of their CIA requirements.

A “zero day” is a loose term for a recently discovered vulnerability and often associated exploit that overturns the above model, i.e. where a vulnerability has been uncovered but rather than being reported to the vendor is being actively exploited (or attempting to be exploited) by malicious parties – before a patch is released and/or implemented – and often before a vendor or its customers are even aware that the vulnerability in question exists.

There are a few things you should look for in a DAST tool, some that are universally recommended, and some the utility of which may depend on your organisation and its unique operating environment. Some of the features that AppCheck believes are most important to be included in your new DAST tool are outlined in this article.
