Securing my device

Practice applying device security guidelines — from creating strong passwords to configuring wireless encryption — using real-world scenarios and multi-step reasoning.

This practice set covers AP Networking Unit 1.4 — practical device and network security. Questions will ask you to interpret scenarios involving:

• Password complexity using all four character sets and minimum length requirements
• Passphrases and why they meet length and usability goals simultaneously
• Account lockout policies and how they defend against brute-force attacks
• Anti-phishing habits including sender verification and link inspection
• VPN usage, HTTPS, and avoiding public Wi-Fi for sensitive sessions
• Software and firmware updates as a security control
• Wireless encryption: WPA3 (recommended), WPA2 (minimum), WEP and WPA (insecure)
• Router hardening: default credentials, SSID, WPS, and Wi-Fi password strength
