Default Security Group is enabled by default to all project servers and includes a few Security Rules which enables access from Servers to external networks and opens ssh connection to Servers.

User can't create any new Security Rule in Default Security Group.

Server Security Group

Server Security Group includes Security Rules for a selected server.

Server name is included in Security Group called "<server hostname>_default".

When Server with optional Application is created, TDS Server Security Group is created automatically including all necessary Security Rules for installed Application.

There is a Project quota limit for Security Rules in public TDS - maximum number of Project Security Rules is the same as maximum number of Servers allowed in the Project

Introduction

By accessing Firewall page on your workspace you can manage access to your servers.

Each server has its own security group. To control access to all servers in bulk, use  __common__ group.

By clicking Show rules link next to each security group you will access firewall rules for specific group.

You can set following properties for every rule:

• Protocol - TCP, UDP, ICMP, Any
• Remote IP/Mask
• Port from - not available for ICMP
• Port to - not available for ICMP
• Note - to improve readability

Workspace Firewall

TDS project Firewall shows security groups where user can manage security rules.

Workspace 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.
