Hello, and welcome to the Practical Guides, books written by Glenn Fleishman, a senior contributor to Macworld, and a regular writer for TidBITS, the Economist, Fast Company, and other publications. 

The latest book in our series is A Practical Guide to Networking, Privacy & Security in iOS 11. It covers a huge range of common setup and routine usage issues, with illustrated step-by-step instructions for carrying out these tasks. The book offers insight into what information you may unintentionally expose about yourself, and how to prevent Apple and third parties from gaining access to your details. It also walks you through security scenarios from securing your data in transit to connecting to a secure Wi-Fi network to recovering or erasing a lost phone.

Apple made substantial changes in areas I cover in this book between iOS 10 and iOS 11. This includes improved automatic blocking of tracking IDs in Safari, built-in support for QR Code (2D code) scanning, better access to networking options in Control Center, changing the way apps ask for your location and iOS displays location tracking,  modifying how Apple ID accounts can be recovered with two-factor authentication enabled, adding the ability to record your screen, offering third-party apps support to let you filter your text messages for spam and abuse, and other areas. It also explains how to use Face ID with an iPhone X.

This book has hundreds of changes since its previous edition that bring it up to date for iOS 11 and cover new features.
