Securing local connections to a host
The database server administrator (DBSA) can use the SECURITY_LOCALCONNECTION configuration parameter to set up security checking for local connections with the same host.
The following table shows the settings of the SECURITY_LOCALCONNECTION configuration
parameter that you can use.
| Setting | Explanation |
|---|---|
| 0 | No security checking occurs. |
| 1 | IBM® Informix® compares the user ID of the owner trying to connect with the connection user ID. If these do not match, IBM Informix rejects the connection. |
| 2 | IBM
Informix performs
the same checking that is performed when SECURITY_LOCALCONNECTION is
set to 1. In addition, IBM
Informix gets the
peer port number from the network API and verifies that the connection
is coming from the client program. If you set SECURITY_LOCALCONNECTION to 2, you must have SOCTCP or IPCSTR network protocols. |
If SECURITY_LOCALCONNECTION is set to 1 or 2, IBM Informix establishes a connection only if the connection meets the requirements of the security check.
