Cheat sheets

Dense one-page references for the things the exam expects you to just know.

• Class "know this" list (colored by domain)

  Every item your instructor starred or said to memorize, on one page, colored by exam domain, with the correct answer next to it.

• Command outputs (know what they look like)

  Sample output of the commands the class starred — nslookup, arp, nbtstat, netstat, route, ping, ipconfig, nmap, grep — with the line to look at in an investigation.

• Security controls matrix (colored)

  Every control category × type on one page, colored by type, with the examples the exam reuses.

• Crypto algorithms (32BRAIDS / DEERQ)

  Hash, symmetric, and asymmetric algorithms on one colored page with key sizes, what's obsolete, and the two memory strings from class.

• OSI model (colored)

  Ronbert-style one-page OSI table — PDU, TCP/IP mapping, protocols, hardware, and the attacks/defenses that live at each layer.

• Ports & protocols (colored)

  Every port the exam expects, colored by verdict — secure (use), insecure (close or replace), normally open, and restrict-to-internal.
