Synopsis
void Auth::setAdvancedSecurity (
mixed $flag = true
)
Описание
Enables advanced security features to make man in the middle attacks and session hijacking much harder. Cookies and java script must be enabled on the client browser for some of these features to function correctly.
Enables the following security features of auth
-
Detection of client ip address change or User-Agent header change if such a change is detected the user will be logged out
-
Each client request a special unique cookie is given to the client. He must present this cookie on his next request. This cookie changes on every request. If client does not present the valid cookie he will be logged out.
-
Enables challenge responce for the default login screen of auth. The user password will be hashed with javascript before sent back to the server. Prevents the user password being stolen using password sniffing tools. Password is hashed with a random key so the md5 hash is not subject to brute force password cracking. This will only work for storage containers which support challenge responce password authenthication. Currently only the DB, MDB and MDB2 containers support this for md5 and clear text passwords
This method is available since
1.3.0
