This document provides a high-level\nworkflow that describes how to configure these components and enable threat\ndetection and prevention.\n\nConfigure intrusion detection and prevention service without TLS inspection\n---------------------------------------------------------------------------\n\nTo configure intrusion detection and prevention service in your network, perform the\nfollowing tasks.\n| **Note:** The following workflow provides a high-level sequence of steps required to configure intrusion detection and prevention service in your network. This workflow assumes that you have already set up your Virtual Private Cloud (VPC) network, subnets, VM instances, and other required Google Cloud resources and components.\n\n1. Create a security profile of type `Threat prevention`. Set up threat or\n severity overrides as required by your network. You can create one\n or more profiles. To learn how to create security profiles,\n see [Create a security profile](/firewall/docs/configure-security-profiles#create-security-profile).\n\n2. Create a security profile group with the security profile created in the\n preceding step. To learn how to create a security profile group,\n see [Create a security profile group](/firewall/docs/configure-security-profile-groups#create-security-profile-group).\n\n3. Create a firewall endpoint in the same zone as your workloads where you want\n to enable threat prevention. To learn how to create\n a firewall endpoint, see [Create a firewall endpoint](/firewall/docs/configure-firewall-endpoints#create-firewall-endpoint).\n\n4. Associate the firewall endpoint with one or more VPC networks\n where you want to enable threat detection and prevention. Make sure that you're\n running your workloads in the same zone as the firewall endpoint. To learn\n how to associate a firewall endpoint with a VPC network,\n see [Create firewall endpoint associations](/firewall/docs/configure-firewall-endpoint-associations#create-endpoint-association).\n\n5. You can use [global network firewall policies](/firewall/docs/network-firewall-policies)\n or [hierarchical firewall policies](/firewall/docs/firewall-policies) to\n configure intrusion detection and prevention service.\n\n - In a new or existing global firewall policy, add a firewall policy rule with\n Layer 7 inspection enabled (`apply_security_profile_group` action) and\n specify the name of the security profile group that you created\n in the preceding step. Make sure that the firewall policy is associated\n with the same VPC network as the workloads that require\n inspection. To learn more about global network firewall policy and the\n parameters required to create a firewall policy rule with threat\n prevention enabled, see [Create global network firewall policy](/firewall/docs/use-network-firewall-policies#create-network-firewall-policy) and\n [Create global network firewall policy rules](/firewall/docs/use-network-firewall-policies#create-rules).\n\n - You can also use a hierarchical firewall policy to add a firewall policy\n rule with a security profile group configured. To learn more about the\n parameters required to create hierarchical firewall policy rules with\n threat prevention enabled, see [Create firewall\n rules](/firewall/docs/using-firewall-policies#create-rules).\n\nConfigure intrusion detection and prevention service with TLS inspection\n------------------------------------------------------------------------\n\nTo configure intrusion detection and prevention service with\n[Transport Layer Security (TLS) inspection](/firewall/docs/about-tls-inspection)\nin your network, perform the following tasks.\n| **Note:** The following workflow provides a high-level sequence of steps required to configure intrusion detection and prevention service with TLS inspection in your network. This workflow assumes that you have already set up your VPC network, subnets, VM instances, and other required Google Cloud resources and components.\n\n1. Create a security profile of type `Threat prevention`. Set up threat or\n severity overrides as required by your network. You can create one\n or more profiles. To learn how to create security profiles,\n see [Create a security profile](/firewall/docs/configure-security-profiles#create-security-profile).\n\n2. Create a security profile group with the security profile created in the\n preceding step. To learn how to create a security profile group,\n see [Create a security profile group](/firewall/docs/configure-security-profile-groups#create-security-profile-group).\n\n3. Create a CA pool and a trust config, and add them to your TLS inspection\n policy. To learn how to enable TLS inspection in Cloud NGFW, see\n [Set up TLS inspection](/firewall/docs/setup-tls-inspection).\n\n4. Create a firewall endpoint in the same zone as your workloads where you want\n to enable threat prevention. To learn how to create\n a firewall endpoint, see [Create a firewall endpoint](/firewall/docs/configure-firewall-endpoints#create-firewall-endpoint).\n\n5. Associate the firewall endpoint with one or more VPC networks\n where you want to enable threat detection and prevention. Add the TLS\n inspection policy you created in the preceding step to the firewall endpoint\n association. Make sure that you're running your workloads in the same zone\n as the firewall endpoint.\n\n To learn how to associate a firewall endpoint with\n a VPC network and enable TLS inspection,\n see [Create firewall endpoint associations](/firewall/docs/configure-firewall-endpoint-associations#create-endpoint-association).\n6. You can use [global network firewall policies](/firewall/docs/network-firewall-policies)\n or [hierarchical firewall policies](/firewall/docs/firewall-policies) to\n configure intrusion detection and prevention service.\n\n - In a new or existing global firewall policy, add a firewall policy rule with\n Layer 7 inspection enabled (`apply_security_profile_group` action) and\n specify the name of the security profile group that you created\n in the preceding step. To enable TLS inspection, specify the\n `--tls-inspect` flag. Make sure that the firewall policy is associated\n with the same VPC network as the workloads that require\n inspection. To learn more about global network firewall policy and the\n parameters required to create a firewall policy rule with threat\n prevention enabled, see [Create global network firewall policy](/firewall/docs/use-network-firewall-policies#create-network-firewall-policy) and\n [Create global network firewall policy rules](/firewall/docs/use-network-firewall-policies#create-rules).\n\n - You can also use a hierarchical firewall policy to add a firewall policy\n rule with a security profile group configured. To learn more about the\n parameters required to create hierarchical firewall policy rules with\n threat prevention enabled, see [Create firewall\n rules](/firewall/docs/using-firewall-policies#create-rules).\n\nExample deployment model\n------------------------\n\nFigure 1 shows an example deployment with intrusion detection and prevention service configured for\ntwo VPC networks in the same region but two different\nzones.\n[](/static/firewall/images/firewall-ips/ips-sample-deployment-in-region.svg) **Figure 1.** Deploy intrusion detection and prevention service in a region (click to enlarge).\n\nThe example deployment has the following threat prevention configuration:\n\n1. Two security profile groups:\n\n 1. `Security profile group 1` with security profile `Security profile 1`.\n\n 2. `Security profile group 2` with security profile `Security profile 2`.\n\n2. Customer VPC 1 (`VPC 1`) has firewall policy with security profile group\n set to `Security profile group 1`.\n\n3. Customer VPC 2 (`VPC 2`) has firewall policy with security profile group\n set to `Security profile group 2`.\n\n4. Firewall endpoint `Firewall endpoint 1` performs threat detection and\n prevention for workloads running on `VPC 1`and`VPC 2` in zone `us-west1-a`.\n\n5. Firewall endpoint `Firewall endpoint 2` performs threat detection and\n prevention with TLS inspection enabled for workloads running on `VPC 1` and\n `VPC 2` in zone `us-west1-b`.\n\nWhat's next\n-----------\n\n- [Security profile overview](/firewall/docs/about-security-profiles)\n- [Security profile group overview](/firewall/docs/about-security-profile-groups)\n- [Firewall endpoint overview](/firewall/docs/about-firewall-endpoints)"]]
