ITPEC FE Subject B April 2026 Question 18

A is RW, RW, R and B is R, RW, R — grant exactly the verbs in Table 1 and nothing beyond them.

Research Proposals:

• •Professors and Researchers create and edit them, so both need RW
• •Students only view them, so R

Experimental Data:

• •only Researchers may create and modify, so RW for them alone
• •Professors and Students review the data, so R for both

Administrative staff are excluded from both types, which the table already fixes.

Answer (c)

Why not others:
- (a) and (b) — give Professors read-only on proposals, although Table 1 has them creating and editing proposals
- (d) and (f) — give Professors write access to experimental data, breaking the stated rule that only Researchers may modify it
- (b), (d) and (f) — deny Students any access to experimental data, although they review it
- (e) and (f) — deny Students access to proposals, although they view them

Key rule: Least privilege turns each verb into a permission: create, edit or modify means RW; view or review means R; anything the requirements do not mention means no access.
