CIS 210 · Information Systems and Cyber Security · Level 200 (Phase Two)
A Royal Army College course in how the Principality's systems work, and how to help run them responsibly.
Course length: 10 hours, studied online and asynchronously at the student's own pace, together with any in-person practical instruction and assessment the course requires.
Foreword
You cannot protect, or help run, what you do not understand. The Principality of Kaharagia depends on a set of online systems, an identity service that holds its accounts, the registers and records that make it a state, the services its people use, the storage that keeps its data, and the network that ties them together. Cyber hygiene, taught in CIS 201, is the habit of using those systems safely. This course goes one layer down, to how the systems themselves are built and kept running, so that a member can understand them, support them, and one day help administer them.
It is written for the willing learner with no assumed background. It explains, in plain terms, what servers and services are; how a network, DNS, and a reverse proxy carry a request to the right place; how services are packaged in containers and run on Linux; how a single identity service signs people in across many systems; what it takes to keep systems patched, monitored, documented, and backed up; where systems are hosted, whether in the cloud or self-hosted; how they are configured and hardened securely; how a small team documents and automates them so they are reproducible; and, above all, how a person trusted with elevated access should conduct themselves. It draws on recognised foundations and on the reality of running a small, self-hosted, sovereign digital estate.
A small force cannot field a large IT department. It can, instead, grow a few capable, disciplined members who understand its systems and treat them with care. That is what this course begins.
Who this course is for
This course is for members moving into the Information Systems and Cyber Security speciality, and for anyone who supports the Army's or the Principality's systems. It assumes CIS 201 · Digital Security and Cyber Hygiene.

How this course fits the catalogue
CIS 210 sits between CIS 201 (everyday cyber hygiene) and CIS 220 · Identity, Access, and Records Security (which deepens the identity and access material introduced here). It supports HCR 220 · Emergency Preparedness and Civil Resilience (continuity) and leads on to CIS 310 · Cyber Incident Response and Continuity. It shares the disciplined, defensive mindset of the SIG Signals speciality.
A note on scope and access
Defensive and lawful throughout. Understanding systems is not the same as being granted access to them: access follows appointment, is limited to what the appointment needs, and is granted only by the authority responsible for the system. This course teaches understanding and responsible conduct, never intrusion.
