Public Instance with service Oracle DB SSL (UDP:2484) is potentially exposed to the public internet
Services and databases store data that may be sensitive, protected by law, subject to regulatory requirements or compliance standards. It is highly recommended that access to data will be restricted to encrypted protocols. This rule detects network settings that may expose data via unencrypted protocol over the public internet or to a too wide local scope.

Instance where isPublic=true and nics contain [ subnet.routeTable.associations length()>0 ] and nics contain [ subnet.routeTable.routes contain [ destinationCidrBlock='0.0.0.0/0' and gatewayId regexMatch /gw/ ] ] should not have inboundRules contain [ port<=2484 and portTo>=2484 and protocol in ('UDP', 'ALL') and scope isPublic() and scope numberOfHosts()>=32 ]
REMEDIATION
Limit the access scope for Instance with service 'Oracle DB SSL to only allow access in internal networks and limited scope.
If public interface exists, remove it and limit the access scope within the VPC only to applications or instances that requires access.
