- The homepage’s sample Linux drill flags a second UID-0 account and SSH root login, alongside a score-and-debrief example.
Field notes
The homepage lists 54 lessons, 265 drill cards, 124 questions, 75 checklist items, and seven domains. Its example debrief scores 24/52 and identifies missed checks such as password reuse and Telnet still being installed. The page says learners can edit forked Linux and Windows checklists, with untouched items inheriting upstream corrections; it also names Sushanth Punuru and an MIT License.
