CompTIA Security+ — Cheat Sheet (2026) cover

CompTIA Security+ — Cheat Sheet (2026)

A printable colour cheat sheet for the CompTIA Security+ (SY0-701) exam, laid out for US Letter and meant to be printed double-sided. It pulls the exam's format, scoring and content areas, and the figures and rules it turns on, onto dense colour-coded pages. Each figure was checked against the source it cites, and the check date is printed on the sheet (October 2026). An independent study aid, not affiliated with or endorsed by the body that sets the exam. The rules an exam tests can change: confirm against the owner's current documents before you rely on a figure.
