Adding Permissions to Security Groups
Adding Permissions to Security Groups
In this section, we'll add permissions to the new security group to allow web traffic via the HTTP and
HTTPS protocols. We'll also add a permission to allow other computers to connect using Windows Remote
Desktop Protocol (RDP).
To add permissions to a security group
1.
In the upper pane of the EC2 Security Groups tab, select a security group.
2.
In the lower pane of the EC2 Security Groups tab, click the Add Permission button.
3.
In the Add IP Permission dialog box, select the Protocol, Port and Network radio button, and then
select HTTP from the Protocol drop-down. The port range automatically adjusts to Port 80, which
is the default port for HTTP. The Source CIDR field defaults to 0.0.0.0/0, which specifies that HTTP
network traffic will be accepted from any external IP address. Click OK.
4.
Repeat this process for HTTPS and RDP. Your security groups permissions should now look like
the following.
You could also set permissions to the security group by specifying a UserID and security group name.
In this case, Amazon EC2 instances in this security group would accept all incoming network traffic from
Amazon EC2 instances in the specified security group. It is necessary to also specify the UserID as a
way to disambiguate the security group name; security group names are not required to be unique across
all of AWS. For more information about security groups, go to the EC2 documentation.
