Module 3.2 - Keeping Your Computer Safe
Keeping your Computer Safe
A Brief History of the Computer Virus
The first computer virus was written in 1971 and was spread on ARPANET, the predecessor to the Internet.1 The virus, known as "the Creeper", was experimental, but not malicious in nature. It didn't damage data, but displayed the playful message "I'm the creeper: catch me if you can".2
Canyons District IT Department Approach
Malware has come a long way since the Creeper. How does the Canyons District IT Department keep your computer safe? It depends on whether you are running a Mac or PC.
The Windows machines in the district have Microsoft Endpoint Protection, which provides virus and malware protection that is centrally managed.
According to Thomas Bailey, Canyon's system engineering team lead, "The Macs that are configured with district standards report various information back to a central location while they are on our network. Part of this information involves indicators of compromise, Adware, Malware etc. We then use this information to remotely cleanup bad files, programs or extensions in many cases.
"So, while this does not prevent infections in and of itself, since [August 29, 2017] I have removed well over a hundred instances of Adware/Malware that [employees] installed on their devices over the summer. So, the short answer is yes, the district takes both proactive and reactive measures to try and keep the Macs safe or remove Adware/Malware etc as we become aware of it. At times this may mean a Field Tech has run [anti-malware software]. In extreme cases, it may mean they need to re-image the machine. We also have teachers and staff self-report problems, at which point a Field Tech looks into it."
The First Line of Defense: YOU!
The human element of the equation is critical. Be cautious while on the Internet. With over a billion websites4 online, one cannot know if every website they visit is "reputable." It takes a bit of savviness, that we will explore in the following pages. First of all, avoid downloading anything unless you are sure of the source. All of the "download" buttons on this page came from the same website. There was a "real" download button on the page, but do you think all the extra download buttons might fool someone?
