Computer viruses, trojan horses, worms, adware, spyware, phishing, ID theft and even more sophisticated threats to online privacy are increasingly in the headlines. Understanding Privacy and Security on the Internet is the topic of the next Central Colorado Humanists Science Sunday program Dec. 1, at 10 a.m. at the Salida Scout Hut, 210 East Sackett Ave.

Tom Roebuck, a veteran technology manager, will present the program, starting with an overview of the origin of the Internet, how it works and cryptography, the foundation of Internet privacy and security. Roebuck will describe how to ensure personal communications are secure, including email, web browsers and social media, and explore what an Internet Service Provider (ISP) may know about its customers and what can be done with that data.

Roebuck founded IoT strategies, a company that helps appliance manufacturers securely connect their products to the Internet. Earlier, he was chief technology officer of Honeywell’s Connected Home business, responsible for new product development: from the devices to wireless communications to cloud infrastructure and mobile and web applications. He led 1,200 engineers in 25 countries. He retired to Salida with his wife, Kelly, in 2016.

The objective of the talk is to provide enough information about the Internet to enable attendees to make informed decisions on privacy and security. A discussion and light refreshments will follow the talk.

Central Colorado Humanists sponsor Sunday Science on the first Sunday of each month. Each presentation is informative and features a topic understandable by both scientists and non-scientists. Doors open at 9:30 a.m., and the talk will start promptly at 10 a.m. Admission is free, and the public is welcome.
