Security Audit and Trailing Functionality
block_user/4 and block_user/5 each blocks the user User from directory Dir for a specified amount of time.
list_auth_users/1, list_auth_users/2, and list_auth_users/3 each returns a list of users that are currently authenticated. Authentications are stored for SecurityAuthTimeout seconds, and then discarded.
list_blocked_users/1, list_blocked_users/2, and list_blocked_users/3 each returns a list of users that are currently blocked from access.
unblock_user/2, unblock_user/3, and unblock_user/4 each removes the user User from the list of blocked users for Port (and Dir).
The SecurityCallbackModule is a user-written module that can receive events from the mod_security Erlang web server API module. This module only exports the functions event/[4,5] which are described here.
event/4 or event/5 is called whenever an event occurs in the mod_security Erlang web server API module. (event/4 is called if Address is undefined, otherwise event/5. Argument What specifies the type of event that has occurred and is one of the following reasons:
A failed user authentication.
A user is being blocked from access.
A user is being removed from the block list.
The event user_unblock is not triggered when a user is removed from the block list explicitly using the unblock_user function.
