Within your course repository, create a directory "hw6". Commit and push to your remote repository.

cd <path_to_repo>
mkdir hw6
touch hw6/app.py
touch hw6/screencast_url.txt
git add hw6
git commit -m "initial commit for hw6"
git push

In this homework, based on the lab exercises, you will create your own LangChain application to orchestrate the use of command and configuration generation functions. Some applications might include

• Automating the use of additional COTS security-related command line tools not used in lab exercises (tcpdump, nessus, nikto, dnsenum, dig, zenmap, BannerGrab, whois, Censys) outside of the ones used in the labs.
• Solving Portswigger, Overthewire, or other CTF exercises using a command generation and execution agent
• Building custom tools to make command invocations more reliable for any of the commands used in labs (e.g. nmap, sqlmap)
• RAG-informed tool from man pages of command to make invocation more reliable
• Multi-tool agent combining tools used in labs

Note that when testing these tools on Google Cloud resources, take care to point them only to the internal IP addresses of servers you deploy on your Google Cloud Project (e.g. 10.x.y.z).

Your development should be organized and incremental, with frequent commits into your git repository. Code should also be properly documented via Python docstrings. In addition, you must also ensure API keys do not show up in your source files, but rather are passed in via environment variables. Ensure your application code is pushed to your repository before class.

Screencast

Upon completing your application, via a narrated screencast of no longer than 5 minutes, you will perform a demonstration and source code walk-through of the application using the script below.

• Check out the application source code from your course repository.
• Demonstrate the application running showing both its capabilities as well as its limitations
• Perform a source code walk-through using your repository on Gitlab to explain how the application has been implemented.

Upload your completed screencast on MediaSpace. Ensure that it is published as "Unlisted". Then, update the file screencast_url.txt in the homework's directory to contain the URL that your unlisted screencast on MediaSpace is located. Push the changes that include the updated URL to your repository before class.

Rubric

We will be using your screencast and git repository to evaluate your homework.
