Google Compute Engine Organization Security Policy Rule

google_compute_organization_security_policy_rule (Terraform)

The Organization Security Policy Rule in Compute Engine can be configured in Terraform with the resource name google_compute_organization_security_policy_rule. The following sections describe how to use the resource and its parameters.

Example Usage from GitHub

An example could not be found in GitHub.

Parameters

The following arguments are supported:

• priority - (Required) An integer indicating the priority of a rule in the list. The priority must be a value between 0 and 2147483647. Rules are evaluated from highest to lowest priority where 0 is the highest priority and 2147483647 is the lowest prority.

• match - (Required) A match condition that incoming traffic is evaluated against. If it evaluates to true, the corresponding 'action' is enforced. Structure is documented below.

• action - (Required) The Action to perform when the client connection triggers the rule. Can currently be either "allow", "deny" or "goto_next".

• policy_id - (Required) The ID of the OrganizationSecurityPolicy this rule applies to.

The match block supports:

• description - (Optional) A description of the rule.

• versioned_expr - (Optional) Preconfigured versioned expression. For organization security policy rules, the only supported type is "FIREWALL". Default value is FIREWALL. Possible values are FIREWALL.

• config - (Required) The configuration options for matching the rule. Structure is documented below.

The config block supports:

• src_ip_ranges - (Optional) Source IP address range in CIDR format. Required for INGRESS rules.

• dest_ip_ranges - (Optional) Destination IP address range in CIDR format. Required for EGRESS rules.

• layer4_config - (Required) Pairs of IP protocols and ports that the rule should match. Structure is documented below.

The layer4_config block supports:

• ip_protocol - (Required) The IP protocol to which this rule applies. The protocol type is required when creating a firewall rule. This value can either be one of the following well known protocol strings (tcp, udp, icmp, esp, ah, ipip, sctp), or the IP protocol number.

• ports - (Optional) An optional list of ports to which this rule applies. This field is only applicable for UDP or TCP protocol. Each entry must be either an integer or a range. If not specified, this rule applies to connections through any port. Example inputs include: ["22"], ["80","443"], and ["12345-12349"].

• description - (Optional) A description of the rule.

• preview - (Optional) If set to true, the specified action is not enforced.

• direction - (Optional) The direction in which this rule applies. If unspecified an INGRESS rule is created. Possible values are INGRESS and EGRESS.

• target_resources - (Optional) A list of network resource URLs to which this rule applies. This field allows you to control which network's VMs get this rule. If this field is left blank, all VMs within the organization will receive the rule.

• enable_logging - (Optional) Denotes whether to enable logging for a particular rule. If logging is enabled, logs will be exported to the configured export destination in Stackdriver.

• target_service_accounts - (Optional) A list of service accounts indicating the sets of instances that are applied with this rule.

In addition to the arguments listed above, the following computed attributes are exported:

• id - an identifier for the resource with format [[policy_id]]/priority/[[priority]]

Tips: Best Practices for The Other Google Compute Engine Resources

In addition to the google_compute_disk, Google Compute Engine has the other resources that should be configured for security reasons. Please check some examples of those resources and precautions.

google_compute_disk

Ensure the encryption key for your GCE disk is stored securely

It is better to store the encryption key for your GCE disk securely. Secret Manager could be used instead.

google_compute_firewall

Ensure your VPC firewall blocks unwanted outbound traffic

It is better to block unwanted outbound traffic not to expose resources in the VPC to unwanted attacks.

google_compute_instance

Ensure appropriate service account is assigned to your GCE instance

It is better to create a custom service account for the instance and assign it.

google_compute_project_metadata

Ensure OS login for your GCE instances is enabled at project level

It is better to enable OS login for your GCE instances. Enabling OS login ensures that SSH keys used to connect to instances are mapped with IAM users, allowing centralized and automated SSH key management.

google_compute_ssl_policy

Ensure to use modern TLS protocols

It's better to adopt TLS v1.2+ instead of outdated TLS protocols.

google_compute_subnetwork

Ensure VPC flow logging is enabled

It is better to enable VPC flow logging. VPC flow logging allows us to audit traffic in your network.
