Cybersecurity - Security Architecture and Design
In a system using the 'Open Design' security pattern, which statement is true?
AUsers must not know how the system works
BSecurity depends on keeping the design secret
CSecurity relies on strong encryption and public algorithms
DSecurity is achieved by hiding all system details
Step-by-Step Solution
Solution:

  1. Step 1: Define Open Design

    This pattern means security should not depend on secrecy of design but on strong, public methods like encryption.

  2. Step 2: Evaluate options

    Security relies on strong encryption and public algorithms correctly states reliance on strong encryption and public algorithms. The other options incorrectly emphasize secrecy or hiding details.

  3. Final Answer:

    Security relies on strong encryption and public algorithms -> Option C

  4. Quick Check:

    Open Design = Security without secrecy of design [OK]
Quick Trick: Open Design trusts strong public methods, not secrecy [OK]
Common Mistakes:
MISTAKES
  • Confusing Open Design with security through obscurity
  • Thinking users must be unaware of system
