Modify the default security group 

Security groups are the policies that deny access to the network ports of an instance. Security groups are therefore firewalls for instances, with a set of default policies that block all access to each port from any source, including the computer you are using to access the Rapid Access Cloud dashboard. Before an instance can be accessed the appropriate ports will need to be opened and a source IP address or range of addresses will need to be configured.

There is a default security group that cannot be deleted, however it can have rules added and removed from it. Additional security groups can also be created depending on need. When a new Rapid Access Cloud account is created, the default security group has four rules. The Egress rules, traffic going out from the instance, is permitted to go out by default. The Ingress rules, traffic going in to the instance, is denied by default since it does not specify any network as seen in the Remote IP Prefix. Thus, a few rules are required to permit basic access.

Modify the default security group

1. Log-in to the Rapid Access Cloud dashboard at https://cloud.cybera.ca.

2. In the left-hand panel under “Compute”, click “Access & Security”.

3. Click the “Security Groups” tab, click the “Manage Rules” button on the right hand side associated with the “default” security group. The list is initially empty, however we are going to add rules that:

1. permit ICMP for ping and traceroute, from any IPv4 or IPv6 address

2. permit ssh from any IPv4 or IPv6 address

4. Click “+Add Rule” in the top right. We are going to be adding four rules. For each rule input the values, then click the blue “Add” button. Note, the first and third rules are for IPv4 access, while the second and fourth are for IPv6:
