Security Practices & Data Protection Flashcards

What is the purpose of enabling FileVault on a Mac?

Answer: Encrypt the startup disk for security

FileVault is Apple's full-disk encryption feature designed to protect the data on a Mac's startup disk. By encrypting the entire disk, it ensures that your information remains unreadable to unauthorized individuals if your device is lost or stolen. This significantly enhances the security and privacy of your personal and sensitive data.

Which feature protects macOS from unauthorized software?

Answer: Gatekeeper

Gatekeeper is a crucial security feature in macOS that helps protect users from installing unauthorized or malicious software. It verifies that applications are signed by identified developers or downloaded from the Mac App Store, preventing potentially harmful programs from running on your system. This acts as a primary defense against malware and untrusted applications.

What should users regularly update to protect their devices?

Answer: Operating systems and apps

Regularly updating operating systems and applications is vital for maintaining device security and performance. These updates often include critical security patches that fix vulnerabilities which could otherwise be exploited by attackers. Neglecting updates leaves devices susceptible to known threats, making them an easy target for malware and data breaches.

Which feature allows remote device management for lost iPhones?

Answer: Find My iPhone

Find My iPhone (now part of the broader 'Find My' app) is an essential Apple service that allows users to remotely locate, lock, or erase their lost or stolen iOS devices. This feature provides critical remote device management capabilities, enabling users to protect their personal data and potentially recover their device. It's a key tool for security and peace of mind.

What type of password policy enhances security?

Answer: Use strong, unique passwords for each account

Using strong, unique passwords for each account is a fundamental security practice. This prevents a single compromised password from granting access to multiple online services, a common tactic known as credential stuffing. Strong, unique passwords significantly reduce the risk of unauthorized access and protect your digital identity across various platforms.

What is a VPN used for?

Answer: Encrypt internet connections and protect privacy

A Virtual Private Network (VPN) creates a secure, encrypted connection over a public network like the internet. Its primary purpose is to protect user privacy and security by encrypting data traffic and masking the user's IP address. This helps prevent eavesdropping, protects sensitive information, and allows for more private browsing.

How can users avoid phishing attacks?

Answer: Verify senders and avoid suspicious links

Phishing attacks attempt to trick users into revealing sensitive information by impersonating trusted entities. To avoid falling victim, users should always verify the sender's legitimacy, scrutinize email content for suspicious links or attachments, and never click on anything unexpected. Exercising caution and skepticism is key to preventing these deceptive scams.

Which macOS feature helps manage app permissions?

Answer: Privacy Settings

In macOS, Privacy Settings (found within System Settings/Preferences) provide granular control over which applications can access sensitive data and system features. Users can manage permissions for location services, contacts, photos, microphone, and more, ensuring their personal information is protected. This empowers users to control their data access and enhance their privacy.

What protects iCloud accounts with an extra layer of security?

Answer: Two-factor authentication

Two-factor authentication (2FA) adds a critical extra layer of security to iCloud accounts. Even if an attacker obtains your password, they cannot access your account without the second verification factor, typically a code sent to a trusted device. This significantly reduces the risk of unauthorized access, making your iCloud account much more secure.
