Active recall and spaced repetition for security concepts

Why it works

Retrieving an answer from memory strengthens it far more than rereading notes, and reviewing just before you would forget is the most efficient schedule. Spaced repetition software such as Anki automates that schedule by showing a card again after increasing intervals when you answer correctly.

Good cards

One fact or relationship per card, phrased as a question that requires recall rather than recognition. Prefer “why” and “which to use when” cards over raw lists. Add your own lab observations, which are easier to remember than textbook phrasing.

• One idea per card
• Question that requires recall
• Include context: when and why
• Add your own lab examples
• Delete cards that never stick and rewrite them

Lab: import a starter deck

Write twenty cards for your current domain in a CSV file with front and back columns, then import them into Anki. Study them daily for a week and note which cards you miss repeatedly. Rewrite those as smaller cards or add an example from your lab.

front,back
Which port and protocol does DNS use for normal queries?,UDP 53 (TCP 53 for large responses and zone transfers)
When is asymmetric encryption preferred over symmetric?,Key exchange and signatures; bulk data uses symmetric for speed
What does a SIEM correlation rule add over a single log search?,It links events across sources and time to raise one alert
Which control type is a security camera?,Detective (also a deterrent)

Limits

Flashcards help with terms and facts but not with procedures. Pair them with hands-on exercises for anything you will need to do, such as reading a packet capture or configuring a firewall rule.
