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() <v>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.
