NAME

       log_mf_h - An Event Handler which Logs Events to Disk

DESCRIPTION

       The  log_mf_h is a gen_event handler module which can be installed in any gen_event process. It logs onto disk all events which are sent to
       an event manager. Each event is written as a binary which makes the logging very fast. However, a tool such as the Report Browser  (  rb  )
       must  be used in order to read the files. The events are written to multiple files. When all files have been used, the first one is re-used
       and overwritten. The directory location, the number of files, and the size of each file are configurable. The directory	will  include  one
       file called index , and report files 1, 2, .... .

EXPORTS

       init(Dir, MaxBytes, MaxFiles)
       init(Dir, MaxBytes, MaxFiles, Pred) -> Args

	      Types  Dir = string()
		     MaxBytes = integer()
		     MaxFiles = 0 < integer() < 256
		     Pred = fun(Event) -> boolean()
		     Event = term()
		     Args = args()

	      Initiates  the  event  handler.  This  function  returns	Args  ,  which should be used in a call to gen_event:add_handler(EventMgr,
	      log_mf_h, Args) .

	      Dir specifies which directory to use for the log files. MaxBytes specifies the size of each individual file. MaxFiles specifies  how
	      many  files  are used. Pred is a predicate function used to filter the events. If no predicate function is specified, all events are
	      logged.

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. Authentica-
	      tions are stored for SecurityAuthTimeout seconds, and are then discarded.

       list_blocked_users(Port) -> Users | []
       list_blocked_users(Address, Port) -> Users | []
       list_blocked_users(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) spec-
	      ified.

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 otherwise). The What argument specifies the type of event that has occurred, and should be one of the fol-
	      lowing 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.
