When you launch the EC2 instance, you can secure access to your instance using a ssh protocol on port 22. You may want to limit the port 22 outbound access on the instance firewall to your IP address.
If you are using X-11 for plotting in octave (gnuplot xterm), you will need to do X-11 forwarding using ssh -Y . You will also need Xquartz installed on your machine and issue xhost + <your instance public IPV4 address>
For qt graphics, you do not need the X-11 forwarding.

This only addresses single user Jupyter notebook server not the multi-user Jupyter Hub server.
