Cheat Sheet

  1. CIA Triad Fundamentals -

    The CIA (Confidentiality, Integrity, Availability) framework underpins every IT security quiz and network security assessment, acting as a mnemonic for core security goals. Confidentiality prevents unauthorized data access, Integrity ensures information accuracy, and Availability guarantees systems remain online when needed (NIST SP 800-53).

  2. Encryption Algorithms: AES vs. RSA -

    Understanding symmetric ciphers like AES (Advanced Encryption Standard) and asymmetric RSA is crucial for a secure IT quiz or cybersecurity quiz. AES uses one secret key for both encryption and decryption, while RSA relies on mathematically linked public/private key pairs (e.g., 2048-bit). Remember "AES = speed, RSA = key exchange" to ace your information security test.

  3. Authentication & Authorization -

    Multi-factor authentication (MFA), single sign-on (SSO), and OAuth are common topics in an information security test and IT security quiz, as they control who gets access and what they can do. MFA combines "something you know, have, or are," significantly boosting security over passwords alone (OWASP Authentication Cheat Sheet).

  4. Common Threats & Vulnerabilities -

    Familiarize yourself with the OWASP Top 10 - especially injection flaws like SQLi and cross-site scripting (XSS) - since many cybersecurity quiz questions focus on these critical web risks. Use the mnemonic "I AM NOT SAFE" (Injection, Authentication, Misconfiguration, etc.) to recall top vulnerabilities rapidly.

  5. Incident Response Lifecycle -

    Whether you're taking a secure IT quiz or a network security assessment, knowing the six SANS steps - Preparation, Identification, Containment, Eradication, Recovery, Lessons Learned - ensures you can quickly map a real-world scenario to theory. Practice mock drills and post-mortems to reinforce each phase and build confidence for your information security test.
