DESCRIPTION

       Security Audit and Trailing Functionality

EXPORTS

       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  each blocks the user User from directory Dir for a
              specified amount of time.

       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 each returns a list  of
              users   that   are   currently   authenticated.   Authentications  are  stored  for
              SecurityAuthTimeout seconds, and 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 each returns a
              list of users that are currently blocked from access.

       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 each removes the user User from
              the list of blocked users for Port (and Dir).

SECURITYCALLBACKMODULE

       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.

EXPORTS

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

              Types:

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

              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:

                auth_fail:
                  A failed user authentication.

                user_block:
                  A user is being blocked from access.

                user_unblock:
                  A user is being removed from the block list.

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