Exam GICSP Topic 1 Question 10 Discussion

Actual exam question for GIAC's GICSP exam
Question #: 10
Topic #: 1
The head of an IT department sent a directive stating that all company communication must use TLS in order to prevent unauthorized disclosure of information. Which part of the C-l-A model is the head of IT concerned with?

Suggested Answer: D Vote an answer

The use of TLS (Transport Layer Security) is intended to encrypt data in transit, thereby preventing unauthorized interception and disclosure.
This is primarily a concern with Confidentiality (D), ensuring information is only accessible to authorized parties.
Identity (A) and Authorization (C) involve user verification and access control but are not the main purpose of TLS.
Availability (B) concerns system uptime.
Integrity (D) ensures data is not altered but encryption mainly addresses confidentiality.
GICSP aligns TLS usage with protecting data confidentiality in ICS communications.
