ITPEC IP April 2024 Question 22
ITPEC IP April 2024 — Question 22 of 100
Secure boot verifies digital signatures on boot software and permits execution only when the signatures are trusted. A device begins from a trusted firmware component and checks the next component in the startup chain, such as a boot loader, OS, or firmware module. Modified or unauthorized code fails verification and is prevented from starting, helping resist persistent tampering in IoT devices and PCs.
Answer (c)
Why not others:
- (a) GPU accelerates parallel computations such as graphics processing
- (b) RAID combines disks for performance, capacity, or data redundancy
- (d) Reboot simply restarts a system and does not itself authenticate startup code
Key rule: Secure boot establishes a chain of trust: each startup component is cryptographically verified before control is passed to it.
