Network View

TDS Project Networks includes TDS Security Groups where user can modify Security Rules related to TDS Servers access.

There is one Security Group named "default" which includes a few default security rules.

For every TDS Server there is created a separate Security Group called "<server hostname>_default".

Project Firewall

Project Firewall view shows all server security groups and common security group attached to all servers.

Each security group is created or removed automatically with project or servers. Users cannot create or remove groups and cannot assign them to other servers.

Common security group

Common security group called "__common__" is attached to all project servers and by default it is empty.

Users can manage rules in common security group the same way as for any servers.

Rules defined here are applied to all servers in project, work with them responsibly!

Server security group

Server security group contains security rules for a relevant server.

Each server security group name is equal to server name.

Managing security rules

Basics:

• User can add a new security rule into security group  byusing button "Add rule".
• User can cancel his actions in security group view simply by going away.
• User can save changes Server Security Group using button "Save".

All security rules are applied for incoming (ingress) connections only. By default NO incoming connection is allowed. Outgoing (egress) connections were always open on all servers, we have removed this option from FW settings.
