Enumeration Type Documentation

enum ast_security_event_severity

the severity of a security event

This is defined as a bit field to make it easy for consumers of the API to subscribe to any combination of the defined severity levels.

XXX

Todo:
Do we need any more levels here?
Enumerator:
AST_SECURITY_EVENT_SEVERITY_INFO 

Informational event, not something that has gone wrong.

AST_SECURITY_EVENT_SEVERITY_ERROR 

Something has gone wrong.

Definition at line 126 of file security_events_defs.h.

                                 {
   /*! \brief Informational event, not something that has gone wrong */
   AST_SECURITY_EVENT_SEVERITY_INFO  = (1 << 0),
   /*! \brief Something has gone wrong */
   AST_SECURITY_EVENT_SEVERITY_ERROR = (1 << 1),
};
enum ast_security_event_transport_type

Transport types.

Enumerator:
AST_SECURITY_EVENT_TRANSPORT_UDP 
AST_SECURITY_EVENT_TRANSPORT_TCP 
AST_SECURITY_EVENT_TRANSPORT_TLS 

Definition at line 136 of file security_events_defs.h.

                                       {
   AST_SECURITY_EVENT_TRANSPORT_UDP,
   AST_SECURITY_EVENT_TRANSPORT_TCP,
   AST_SECURITY_EVENT_TRANSPORT_TLS,
};
enum ast_security_event_type

Security event types.

AST_EVENT_SECURITY is the event type of an ast_event generated as a security event. The event will have an information element of type AST_EVENT_IE_SECURITY_EVENT which identifies the security event sub-type. This enum defines the possible values for this sub-type.

Enumerator:
AST_SECURITY_EVENT_FAILED_ACL 

Failed ACL.

This security event should be generated when an incoming request was made, but was denied due to configured IP address access control lists.

AST_SECURITY_EVENT_INVAL_ACCT_ID 

Invalid Account ID.

This event is used when an invalid account identifier is supplied during authentication. For example, if an invalid username is given, this event should be used.

AST_SECURITY_EVENT_SESSION_LIMIT 

Session limit reached.

A request has been denied because a configured session limit has been reached, such as a call limit.

AST_SECURITY_EVENT_MEM_LIMIT 

Memory limit reached.

A request has been denied because a configured memory limit has been reached.

AST_SECURITY_EVENT_LOAD_AVG 

Load Average limit reached.

A request has been denied because a configured load average limit has been reached.

AST_SECURITY_EVENT_REQ_NO_SUPPORT 

A request was made that we understand, but do not support.

AST_SECURITY_EVENT_REQ_NOT_ALLOWED 

A request was made that is not allowed.

AST_SECURITY_EVENT_AUTH_METHOD_NOT_ALLOWED 

The attempted authentication method is not allowed.

AST_SECURITY_EVENT_REQ_BAD_FORMAT 

Request received with bad formatting.

AST_SECURITY_EVENT_SUCCESSFUL_AUTH 

FYI FWIW, Successful authentication has occurred.

AST_SECURITY_EVENT_UNEXPECTED_ADDR 

An unexpected source address was seen for a session in progress.

AST_SECURITY_EVENT_CHAL_RESP_FAILED 

An attempt at challenge/response authentication failed.

AST_SECURITY_EVENT_INVAL_PASSWORD 

An attempt at basic password authentication failed.
