About this site

secplus is my personal study guide for the CompTIA Security+ SY0-701 exam. It follows the official objectives one by one: notes broken down per objective with a quiz at the end of each section, whole-domain quizzes, fixed practice tests, a timed mock exam weighted like the real thing, the official acronym list as flashcards, and dense cheat sheets. Progress is saved only in your browser — there are no accounts and no server-side tracking.

Right now: notes for 28 of 28 objectives, 326 section questions, and 50 practice-test questions.

Where the material comes from

• My class notebook

  The primary source. Every objective page quotes the instructor's framing in “From class” callouts, every item I starred in the notebook is marked ★, and each note lists the notebook pages it was built from in its Sources line. Where my notes disagreed with CompTIA's definitions, the page says so instead of silently correcting it.

• CompTIA Security+ SY0-701 Exam Objectives (v5.0)

  The official objectives document defines the 5 domains, 28 objectives, exam weights, and the acronym list used for the flashcards and acronym quiz. CompTIA and Security+ are trademarks of CompTIA, Inc.; this site is not affiliated with or endorsed by CompTIA.

• ronbert.com — OSI Model and Security+ pages

  Inspiration for the dense one-page cheat sheets, the colored OSI layer table, the hash/symmetric/asymmetric algorithm table, the extended multifactor table, and the two memory strings 3 2 B R A I D S and D E E R Q. Also http://ronbert.com/Security+.htm.

• ExamCompass

  Model for the practice-test format: 25-question sets, one question per page, results with explanations at the end, and acronym quizzes. No questions were copied; every question here was written for this site.

• Frameworks and standards referenced

  NIST SP 800-207 (Zero Trust architecture), NIST SP 800-63B (digital identity / password guidance), the Lockheed Martin Cyber Kill Chain, the Diamond Model of Intrusion Analysis, MITRE ATT&CK, the OWASP Top 10, CVSS/CVE, and CIS Benchmarks. Each is credited where it appears.

• Study assistant (Ask AI)

  The assistant answers from this site only: your question is matched against the same index the search box uses, and the top sections are handed to a local Llama 3.2 model running on the home-lab cluster's Jetson node. Nothing is sent to an external AI service, and questions aren't stored. It cites the sections it used — always check the link, because a small model can still get details wrong.

• Explanations, questions, and diagrams

  Written for this site, drafted with Claude Code from the notebook and the objectives, then reviewed by me. Mistakes are mine — if a question or note looks wrong, it probably is; check it against the objectives and tell me.

How it’s built

Next.js, React, TypeScript, and Tailwind CSS. All content is versioned markdown and JSON; every page is prerendered at build time and shipped as a container to my home-lab Kubernetes cluster. Search and the study assistant share one index built at compile time; the assistant streams its answer from a self-hosted model in the same cluster. Diagrams are inline SVG that recolors with the theme picker in the header. Source: github.com/p0dxD/secplus. More projects at joserod.space.
