Last updated 1 year ago

  1. Navigate to Security tab. You'll see that most of the sections are pending sync.

  2. Click Firewall sync on each server (APP1, APP2, ALB)

Once the sync is complete you should see the current Firewall Status and what Security Polices are applied. Notice that the policy Allow my IP addresses to entire cluster that we created in step 1 is also listed here.

  1. Click Apply policies on each server (APP1, APP2, ALB)

  2. Applying Security Policies to the server firewall configuration requires root privileges. Provide Root password and click OK

When the changes are applied, the Security Policies section collapses. You can always expand it if you want to see the list of policies applicable to the server.

  1. Now you can Activate the firewall for each server (APP1, APP2, ALB)

  2. Activating the firewall on the server requires root privileges too. Provide Root password and click OK

Once all Security Policies are applied and the Firewall is active ClusterWare will confirm that with a green check mark in both of these sections.

  1. Verify that APP1 and APP2 servers are not accessible on respective application ports (8000, 8001 on APP1 and 9000, 9001 on APP2)

  1. Verify that anyone can still access the ALB server and that the ALB server can talk to APP1 and APP2 server

  1. If you provided your current IP address correctly in step 1, you should be able to SSH into any of the servers on port 22.

Congratulations! You have secured access to all the servers in your cluster!
