OCI VCN has no inbound security list

Description

This policy identifies the OCI Virtual Cloud Networks (VCN) that lack ingress rules configured in their security lists. It is recommended that Virtual Cloud Networks (VCN) security lists are configured with ingress rules which provide stateful and stateless firewall capability to control network access to your instances.

Code Example

resource "oci_core_security_list" "pass" {
    compartment_id = oci_identity_compartment.tf-compartment.id
    vcn_id = oci_core_vcn.test_vcn.id
+    ingress_security_rules {
+        protocol = "all"
+        source="192.168.1.0/24"
+    }
}
