Home Computer Security -- Human Behavior - Part II
http://edu-observatory.org/olli/HCS/Week2.html


WE ARE A CLEAR AND PRESENT DANGER

  


WHAT IS A SECURE CONNECTION TO THE INTERNET?
  Cellular connections (not Wi-Fi) are encrypted and SECURE.

  Wi-Fi at Universities, Hotels, Libraries, Coffee Shops, etc.
  IS NOT SECURE. Any computer on those networks may have
  malware harvesting EVERYTHING you say, type and read.

  When using a public Wi-Fi network use a VPN. A VPN secures
  your device's internet connection to guarantee that all data
  you are sending and receiving is encrypted and secure from
  prying eyes. Iowa State requires its students to use a VPN.
  Some excellent VPN services: Tunnelbear, ExpressVPN, ProXPN,
  NordVPN, and TotalVPN.

Dropbox (Free service for all platforms)
  https://www.dropbox.com
  https://www.dropbox.com/downloading
  
  Dropbox is a file hosting service operated by Dropbox, Inc.,
  headquartered in San Francisco, California, that offers
  cloud storage, file synchronization, and client software.
  Dropbox allows users to create a special folder on each of
  their computers, which Dropbox then synchronizes so that it
  appears to be the same folder (with the same contents)
  regardless of which computer is used to view it. Files
  placed in this folder also are accessible through a website
  and mobile phone applications.

  One can backup specified files and folders to Dropbox using
  symbolic links via the command line. For example:
  ln -is ~/Documents ~/Dropbox/Documents

  Anything added, deleted or changed on the PC/Mac is replicated
  in Dropbox and vice versa. Deleting File/Folder in Dropbox
  also deletes it immediately from the PC/Mac! Just so you know.

Ad Blockers and Tracking Blockers (use all three)

  AdBlock Plus is a free extension that allows you to block
  annoying ads, disable tracking and block domains known to
  spread malware. Available for iOS, Android, Chrome, Firefox,
  Internet Explorer, and Safari, Adblock Plus uses filters
  that you choose to block all unwanted elements.
  
  DuckDuckGo Privacy Essentials offers users state-of-the-art
  tools so that they can protect their sensitive data when
  browsing the Internet. It is equipped with several advanced
  features. For instance, this software package is able to
  detect those sites which are associated with hidden tracking
  algorithms. These are pointed out to the user and the
  programs can often be disabled. Forced encryption will
  likewise add an additional layer of protection; eliminating
  cookies and other data collection techniques. There are also
  times when privacy policies are rated in terms of their
  transparency.
  
  Ghostery is also a free extension that puts the power in
  your hands to choose what to block, on a tracker-by-tracker
  or site-by-site basis, or combination of the two.
