Terence L Sadler

After spending 41 years protecting critical information systems in both military and civilian roles, Terence Lee Sadler realized the greatest threat wasn't a complex hack; it was a simple lack of practical knowledge. Frustrated by seeing countless home users and small businesses fall victim to preventable attacks, Terence decided to write the guide he wished everyone had. Terence’s mission is to translate his deep experience in information assurance and security program management; including military Operations Security (OPSEC) principles, into secure habits for everyone. This book is the culmination of his four-decade career, built to empower you to secure your digital life without needing a tech degree. (Friends and family call him Terry.)
