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 SecurityAuthTimeout 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  otherwise).  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.
