Description
|
|
-----------
|
|
Encryption in general is typically critical to the security of many
|
|
applications. Using TLS can greatly increase security by guaranteeing the
|
|
identity of the party you are communicating with. This is accomplished by one
|
|
or both parties presenting trusted certificates during the connection
|
|
initialization phase of TLS.
|
|
|
|
When request methods are used certificates are validated automatically which is
|
|
the desired behavior. If certificate validation is explicitly turned off
|
|
Bandit will return a HIGH severity error.
|
|
