UniFi Dream Machine for AI-Based Network Security Threat Management.

Question

Pulumi · Accepted Answer

The UniFi Dream Machine (UDM) is a device from Ubiquiti Networks that combines a router, a switch with PoE, and Wi-Fi access point capabilities, along with advanced security features and network management into a single unit.

When it comes to managing the UDM and associated networking equipment with Pulumi, you can make use of the `pulumi_unifi` provider. This provider allows you to manage UniFi devices and configurations programmatically, which includes setting up LAN/WAN networks, WLAN (Wi-Fi Networks), firewall rules, and various network configurations crucial for network security and threat management.

Here's a basic Pulumi program that illustrates how you may configure network settings and security on a UDM device using the `pulumi_unifi` provider. In this example, we create a network and configure a firewall rule which can be part of an AI-based network security threat management system:

```python
import pulumi
import pulumi_unifi as unifi

# Configure the site where we want to manage our devices.
site = unifi.Site(
    "site",
    description="My UniFi Site"
)

# Create a new network within the UniFi controller.
network = unifi.Network(
    "network",
    name="MySecureNetwork",
    site=site.name,
    purpose="corporate",  # Possible values are "corporate" or "guest", among others.
    subnet="192.168.1.1/24",  # The subnet for the network.
    vlan_id=10,  # VLAN id for the network.
    dhcp_enabled=True,
    domain_name="secure.local",  # Local domain name for the network.
    is_guest=False,
)

# Define a firewall rule that could be part of an AI-based network security system.
# Rules can be set to allow or block traffic based on certain conditions, which could be dynamically updated by AI-driven analytics.
firewall_rule = unifi.firewall.Rule(
    "firewallRule",
    name="BlockUnsecureTraffic",
    site=site.name,
    action="drop",  # "drop" to block traffic, "accept" to allow it.
    ruleset="WAN_OUT",  # Apply this rule for outbound WAN traffic.
    protocol="any",  # Define the protocol; could be "TCP", "UDP", etc. "any" applies to all.
    source_network="LAN",  # Traffic originating from the LAN network.
    destination_network="any",  # Traffic going to any destination.
    rule_index=2000,  # The order in which the rule should be applied.
    logging=True,  # Enable logging for the rule - useful for monitoring and AI-based analysis.
)

pulumi.export("network_id", network.id)
pulumi.export("firewall_rule_id", firewall_rule.id)
```

In this example, you are defining a secure local network designated as "corporate" within the site and setting conditions for traffic (purpose, subnet, VLAN ID). The DHCP is enabled for automatic IP address assignment within the specified subnet. Meanwhile, the firewall rule is a crucial part of the network security setup, where you specify to block (drop) all outbound WAN traffic that is deemed unsecure by your AI-based threat management systems.

The `uni.Network` resource is used to create the network and the `uni.firewall.Rule` resource to set up the firewall rule. The `site.name` property is used to specify the site under which all other resources are managed.

The `pulumi.export` statements at the end of the program ensure that you can access the ID of the created resources after deployment. These IDs could be used to further interact with the resources via Pulumi or the UniFi Controller UI/API.

Remember to configure your UniFi provider with the correct settings to interact with your UniFi Controller, and ensure that your Pulumi environment is set up with the necessary permissions and network access to manage your UDM device.
