Security Flashcards

200+ interactive security flashcards across 10 topics with flip-card UI and spaced repetition progress tracking. Free, no login.

Security Flashcards provides 200+ interactive study cards across 10 cybersecurity topic decks. Cards use a flip-card interface — you see the question or term, flip the card to see the answer, then mark it as known or needs review. The spaced repetition system tracks which cards you struggle with and surfaces them more frequently, focusing your study time where it matters most.

The 10 topic decks cover: Email Security (SPF, DKIM, DMARC, header analysis), Network Security (TCP/IP, protocols, firewall concepts), Threat Intelligence (IOC types, threat feeds, attribution), Malware Analysis (static and dynamic analysis, PE format), Identity and Access Management (authentication, MFA, PAM), Incident Response (PICERL framework, triage, containment), GRC and Compliance (NIST, ISO 27001, GDPR, PCI-DSS), Cryptography (symmetric, asymmetric, PKI, TLS), Cloud Security (shared responsibility, AWS/Azure services, misconfigurations), and Security Operations (SIEM, SOC tiers, alert handling).

Flashcards are an effective study method for the terminology-heavy content in cybersecurity certification exams like CompTIA Security+, CySA+, and SSCP. The DuckIntel deck is written specifically for practical analyst work, not just exam definitions — each card explains not just what a term means but why it matters and how it appears in real security work.
