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.
