ITPEC IP April 2024 Question 36

Setting a screen lock with a password — if the smartphone is lost, stolen or left unattended, no one else can open it and read its data.

A smartphone holds e-mail, contacts, photos and logged-in accounts. A screen lock with a password, PIN or biometric authentication stops a third party who picks up the device from using it. Secure use also means keeping the OS up to date, leaving the manufacturer's security restrictions in place, and installing apps only from the official app store.

Answer (c)

Why not others:

• •(a) — never updating the OS leaves known vulnerabilities unfixed; OS updates include the security patches for them
• •(b) — jailbreaking removes the restrictions the OS places on apps, disabling built-in protections and exposing the device to malware
• •(d) — apps downloaded from arbitrary websites skip the review of the official store and may be malware posing as a useful tool

Key rule: Smartphone security rests on four habits: lock the screen, keep the OS updated, never jailbreak, and install apps only from trusted sources.
