Experiment with Symmetric Cryptography

Configuring a Security Group

Once an EC2 instance is running, we can

connect to it. However, we must make

sure that connections are limited to the

individual student who created the

instance. Security groups provide this

ability by allowing the user to specify a

unique IP address to connect to the

instance.

From the EC2 instance dashboard, select

the instance and then select the security

group launch wizard as shown below.

From the Security Groups page, select

the Inbound rules tab and then click Edit

inbound rules.

From the Source dropdown menu, select

MyIP. The form will automatically

populate your desktop IP address. Enter

a description into the description field

and click Save rules.

Now, only the desktop device with

specific IP address in the inbound rule

will be able to successfully connect to

the EC2 instance.
