An NSG that Is Stateful, Names Its Sources, and Says What It Cannot Do
An NSG with no rules admits nothing and sends nothing, so a group written with ingress only has VNICs that cannot resolve DNS; a stateless rule drops every reply that has no matching egress; and the subnet's security list still applies, unioned with the NSG. Stateful always, egress explicit and open by default, SSH from 0.0.0.0/0 refused unless accepted, the security list named as still applying.

Documentation
oci-network-security-group
An OCI network security group whose rules are stateful and name their
sources, and that says what it does not do. Works with Terraform and
OpenTofu (>= 1.6), oci provider >= 8.0, < 9.0.
An NSG with no rules admits nothing and sends nothing. Egress is explicit; the default opens it.
Stateful, always; the security list still applies
(overrides_security_list is always false).
SSH from 0.0.0.0/0 needs accept_ssh_from_anywhere.
Verification
Static validation runs tofu fmt, init, validate, tflint and checkov.
This module has not yet had a live test, so it is published as statically
validated with its live test pending and does not carry the live-tested mark.

oci-cloud-guard
Oracle ships every responder rule in USERACTION mode: a Remediate button appears on each problem and nothing happens until a person clicks it, so a tenancy with hundreds of findings has by default fixed none of them. Sets AUTOACTION per rule and exports the IAM statements each auto-action needs, since one without its policy fails on every execution.
oci-security-zone
The opposite of every other guardrail here: a security zone does not detect or report, it REFUSES - the API call fails. There is no dry-run mode. So the risk inverts too: applied to a compartment that already holds non-compliant resources, the team that owns them discovers they can no longer change them.
oci-network-firewall
An INSPECT rule hands the flow to the threat engine, and inspection decides what happens next: INTRUSION_PREVENTION drops the session, INTRUSION_DETECTION logs it and forwards it, and the rule reads INSPECT either way. Every inspect rule is prevention unless detection is accepted by name; policy and appliance are both created, and the address the route tables must point at is an output.
oci-waf
CHECK is the action that evaluates the rule, logs the match and lets the request through - the console shows the protection rules and every matched attack reached the backend. BLOCK by default, DETECT only by name. The policy and the firewall binding it to a load balancer are separate resources; both are created, and a policy alone has to be asked for.
oci-bastion
Zero-footprint managed bastion with session-managed SSH/port-forward access to private subnets - replaces jump hosts.
oci-vulnerability-scanning
scan_level = NONE is legal for both the agent scan and the port scan, so a recipe with both at NONE runs on schedule, updates its last-run time, and finds nothing because it looked for nothing. A recipe is not a target either: one with no target scans no instance. Refuses a recipe that scans for nothing and always creates the target with it.
