CS615A -- Aspects of System Administration
By enrolling in this class, you all have chosen the red pill already. You are now in Wonderland, and will soon see how deep the rabbit hole goes.
The Reliable CS615 Sorting Hat has identified you as a prime cadidate for one of the following guilds: Correctness and Quality (Black Team), the Adversarial View of the Breakers (Red Team), the noble Builders and Defenders (Blue Team), or Guardians of Usability and Performance (Green Team).
Each team is expected to focus on their area of expertise throughout the semester, to challenge our thinking, our solutions, and how we address the problems we encounter to ensure their objective is met. In so doing, each team will:
No team is inherently superior, and all areas of focus have clear advantages and disadvantages, with the benefits and tradeoffs of the different approaches not always obvious. Click the name of each team to see how the Sorting Hat judged you:
The Black Team focuses on correctness and quality. The team assures that programs and protocols follow their specification, that adequate documentation exists, that systems implement solutions correctly and according to the highest quality standards. Shortcuts are not appreciated, and correctness must be proven, not assumed.
The Red Team will do anything to break your tool, to abuse your system, to wreak havoc. Creative ways to utilize unexpected input or exploiting loopholes in the implementation or definition of a system or protocol are pars for the course. However, the team also must focus on specific objectives and must avoid being detected.
The Blue Team defends the system, ensures it remains functional and usable, makes things (continue to) run. A deep understanding of the ways the system could be abused is necessary to build strong defenses; creative applications of threat detection mechanisms are mixed with functional requirements, aspects of observability, always ensuring the owners of the systems don't lose control.
The Green Team does not tolerate inefficiencies, and unintuitive user interfaces are a thorn in their side. Systems need to operate at peak efficiency, regardless of the circumstances they are exposed to; at the same time, the team understands that cumbersome UIs lead to a plethora of problems. The Green Team advocates for the user, balancing performance requirements while ensuring the systems spark joy.
