System Access Control
You can configure a system access control list (ACL) for your Oracle® Enterprise Session Border Controller that determines what traffic the Oracle® Enterprise Session Border Controller allows over its management interface (wancom0). By specifying who has access to the Oracle® Enterprise Session Border Controller via the management interface, you can provide DoS protection for this interface.
Using a list of IP addresses and subnets that are allowable as packet sources, you can configure what traffic the Oracle® Enterprise Session Border Controller accepts and what it denies. All IP packets arriving on the management interface are subject; if it does not match your configuration for system ACL, then the Oracle® Enterprise Session Border Controller drops it.
Note:
All IP addresses configured in the SNMP community table are automatically permitted.
