3 - Turn off DDOS protection plan

You can choose to not deploy a DDOS protection plan. In order to do that, they need to remove the DDOS protection plan configuration and disable the DINE (deploy if not exists) policy. You can either comment out or remove the configuration entirely.

DDOS Protection plan is a critical security protection for public facing services. Carefully consider this and be sure to put in place an alternative solution, such as per IP protection.

The steps to follow are:

1. Update the following settings by searching for the keys and updating the value

   Setting Type	Parent block(s)	Key	Action	Count	Notes
   line	custom_replacements > names	ddos_protection_plan_enabled	Update setting to false	1

2. Locate the lib folder in your config directory. This folder was created in the initial steps of phase 2. The lib folder structure should look like this:

   📂lib
   ┣ 📜alz_library_metadata.json
   ┣ 📂architecture_definitions
   ┃ ┗ 📜alz_custom.alz_architecture_definition.yaml
   ┗ 📂archetype_overrides
     ┃ 📜connectivity_custom.alz_archetype_override.yaml
     ┃ 📜corp_custom.alz_archetype_override.yaml
     ┃ 📜decommissioned_custom.alz_archetype_override.yaml
     ┃ 📜identity_custom.alz_archetype_override.yaml
     ┃ 📜management_custom.alz_archetype_override.yaml
     ┃ 📜landing_zones_custom.alz_archetype_override.yaml
     ┃ 📜platform_custom.alz_archetype_override.yaml
     ┃ 📜root_custom.alz_archetype_override.yaml
     ┗ 📜sandboxes_custom.alz_archetype_override.yaml
   

3. Open the landing_zones_custom.alz_archetype_override.yaml file and uncomment the AMA policy assignments in the policy_assignments_to_remove list.

   The file should look like this:

   base_archetype: landing_zones
   name: landing_zones_custom
   policy_assignments_to_add: []
   policy_assignments_to_remove: [
   # To remove AMA policies, uncomment the following lines:
     # Deploy-MDFC-DefSQL-AMA,
     # Deploy-VM-ChangeTrack,
     # Deploy-VM-Monitoring,
     # Deploy-vmArc-ChangeTrack,
     # Deploy-vmHybr-Monitoring,
     # Deploy-VMSS-ChangeTrack,
     # Deploy-VMSS-Monitoring,
   # To remove the DDOS modify policy, uncomment the following line:
     Enable-DDoS-VNET,
   ]
   policy_definitions_to_add: []
   policy_definitions_to_remove: []
   policy_set_definitions_to_add: []
   policy_set_definitions_to_remove: []
   role_definitions_to_add: []
   role_definitions_to_remove: []
   

4. Open the connectivity_custom.alz_archetype_override.yaml file and update it to look like this:

   base_archetype: connectivity
   name: connectivity_custom
   policy_assignments_to_add: []
   policy_assignments_to_remove: [
   # To remove the DDOS modify policy, uncomment the following line:
     Enable-DDoS-VNET,
   ]
   policy_definitions_to_add: []
   policy_definitions_to_remove: []
   policy_set_definitions_to_add: []
   policy_set_definitions_to_remove: []
   role_definitions_to_add: []
   role_definitions_to_remove: []
   

5. Make sure to save both files after making the changes.
