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.
