mod_security(3erl)		     Erlang Module Definition		       mod_security(3erl)

NAME
       mod_security - Security Audit and Trailing Functionality

DESCRIPTION
       Security Audit and Trailing Functionality

EXPORTS
       list_auth_users(Port) -> Users | []
       list_auth_users(Address, Port) -> Users | []
       list_auth_users(Port, Dir) -> Users | []
       list_auth_users(Address, Port, Dir) -> Users | []

	      Types  Port = integer()
		     Address = {A,B,C,D} | string() | undefined
		     Dir = string()
		     Users = list() = [string()]

	      list_auth_users/1 , list_auth_users/2 and list_auth_users/3 returns a list of users
	      that are currently authenticated. Authentications are stored for	SecurityAuthTime-
	      out seconds, and are then discarded.

       list_blocked_users(Port) -> Users | []
       list_blocked_users(Address, Port) -> Users | []
       list_blocked_users(Port, Dir) -> Users | []
       list_blocked_users(Address, Port, Dir) -> Users | []

	      Types  Port = integer()
		     Address = {A,B,C,D} | string() | undefined
		     Dir = string()
		     Users = list() = [string()]

	      list_blocked_users/1 , list_blocked_users/2 and list_blocked_users/3 returns a list
	      of users that are currently blocked from access.

       block_user(User, Port, Dir, Seconds) -> true | {error, Reason}
       block_user(User, Address, Port, Dir, Seconds) -> true | {error, Reason}

	      Types  User = string()
		     Port = integer()
		     Address = {A,B,C,D} | string() | undefined
		     Dir = string()
		     Seconds = integer() | infinity
		     Reason = no_such_directory

	      block_user/4 and block_user/5 blocks the user User from the  directory  Dir  for	a
	      specified amount of time.

       unblock_user(User, Port) -> true | {error, Reason}
       unblock_user(User, Address, Port) -> true | {error, Reason}
       unblock_user(User, Port, Dir) -> true | {error, Reason}
       unblock_user(User, Address, Port, Dir) -> true | {error, Reason}

	      Types  User = string()
		     Port = integer()
		     Address = {A,B,C,D} | string() | undefined
		     Dir = string()
		     Reason = term()

	      unblock_user/2  ,  unblock_user/3 and unblock_user/4 removes the user User from the
	      list of blocked users for the Port (and Dir) specified.

THE SECURITYCALLBACKMODULE
       The SecurityCallbackModule is a user written module  that  can  receive	events	from  the
       mod_security  Erlang  Webserver	API  module.  This  module  only exports the function(s),
       event/4,5 , which are described below.

EXPORTS
       event(What, Port, Dir, Data) -> ignored
       event(What, Address, Port, Dir, Data) -> ignored

	      Types  What = atom()
		     Port = integer()
		     Address = {A,B,C,D} | string() <v>Dir = string()
		     Data = [Info]
		     Info = {Name, Value}

	      event/4 or event/4 is called whenever an event occurs in	the  mod_security  Erlang
	      Webserver API module ( event/4 is called if Address is undefined and event/5 other-
	      wise). The What argument specifies the type of event that has occurred, and  should
	      be  one  of  the	following  reasons;  auth_fail	(a  failed  user authentication),
	      user_block (a user is being blocked from access) or user_unblock (a user	is  being
	      removed from the block list).

   Note:
       Note  that  the	user_unblock event is not triggered when a user is removed from the block
       list explicitly using the unblock_user function.
