Configure Cross-Network Protection

Cross-network protection functionality within the Alert Logic® console allows you to leverage the appliance installed in one network to protect other networks under the same account. The following information walks you through configuring this protection and, if necessary, removing the connection from a network.

This functionality has prerequisites:

• Only available in manual deployments of Amazon Web Services, Microsoft Azure, and data centers
• Appliances and agents must be installed in applicable networks
• Networks must be within the same Alert Logic customer account
• Hosts from the networks must already be able to connect with one another

Configure Cross-Network Protection

1. Within the Alert Logic console, navigate to Configure (or Configuration) > Deployments > desired manual deployment > Protection > Options.
   
   
2. From the topology view in Options, click on the agent-deployed network you would like to be protected by another network.
   
   
3. Within the search bar, find the appliance-deployed network you would like to do the protecting by either searching for its name or clicking on the search bar and scrolling through the network options that appear. Click on the desired network name.
   
   
4. The protected network now appears blue (), as does the protecting network ().
   
   Note: The protecting network now also has two arrows pointing toward each other within the cloud.
   
   
5. Click Save above the topology view.

Cross-Network Protection Over the Internet

Alert Logic highly recommends utilizing local or VPN-protected connections when enabling cross-network protection, but when you must utilize cross-network protection on an appliance configured with a public IP address, there are two requirements:

• Associated agents must have a route to connect to the appliance via the internet
• Appliance firewall rules must be configured to allow connections on port 7777.

Note that any traffic sent via a public IP address is automatically encrypted, and encryption of traffic increases data size. This may be a concern for some customers.

View Protected Networks

Use the following process to see all the networks that your protecting network is connected to.

1. Click on the protecting network whose connections you would like to see.
   
   
2. Click on the blue icon with bullet points ().
   
   
3. A sidebar will appear with a list of the networks being protected by your chosen protecting network.

Remove Cross-Network Protection Connection

1. Click on the protected network whose connection you would like to remove.
   
   
2. Click on the blue icon with two arrows pointing toward each other ().
   
   
3. Confirm the connection removal by clicking Delete.
