Difficulty: EasyCIA Triad & Core Security Concepts

A network administrator implements cryptographic hashing algorithms to verify that transmitted configuration files are not altered or tampered with during transit. Which core pillar of the CIA triad is the administrator primarily protecting?

  1. IntegrityAnswer
  2. B
    Confidentiality
  3. C
    Availability
  4. D
    Accounting

Answer

Integrity
Integrity ensures that information is protected against unauthorized modification, tampering, or corruption. Using cryptographic hashes to verify that files arrive unaltered directly fulfills the integrity requirement of the CIA triad.

Step-by-Step Solution

1
Analyze the technical control described in the scenario.
The control uses cryptographic hashing to detect whether configuration files have been altered or modified in transit.
Hashing produces a unique checksum value that changes if any bit of data is altered.
2
Map the control's objective to the pillars of the CIA triad.
Preventing unauthorized alteration and guaranteeing data trustworthiness directly maps to Integrity.
Integrity focuses on guarding against improper data modification or destruction.
