Footprinting Secure ROS systems

Following from the previous tutorial, in this one we'll analyze secure ROS setups using the SROS package.

---

Note: as in previous tutorials, there's a docker container that facilitates reproducing the work of this tutorial. The container can be built with:

docker build -t basic_cybersecurity_footprinting2:latest .

and runned with:

docker run --privileged -it basic_cybersecurity_footprinting2:latest

Understanding SROS

According to [5], SROS has three levels of concepts: the Transport Security level, the Access Control level, and the Process Profile level. These levels and concepts are summarized below and later sections go into each of these in greater detail.

[4] provides some additional intuition about each one of these levels.
