About the Flashcards

Flashcards for the ISC2 CISSP exam give you a quick way to review the core language of modern information security and networking. Each card distills a critical acronym or term-from AAA and AES to VPN and XSS-so you can recall definitions fast during practice sessions or on test day.

The deck spans authentication models, cryptographic algorithms, network protocols, risk calculations, cloud service models, governance frameworks, business continuity planning, and incident-response functions. By linking abbreviations to their full meanings, it reinforces key principles the exam measures, including confidentiality, integrity, availability, secure design, and operational resilience.

Topics covered in this flashcard deck:

Authentication & access control
Cryptography fundamentals
Network & internet protocols
Risk & business continuity
Governance standards & frameworks
Cloud and virtualization services
