We take a look at the surprisingly involved process of downloading software from a trustworthy source, as well as the history of why desktop OSes are so vulnerable. Also,...

  10. Backups

    Backups are an important part of keeping your devices secure - as mentioned last episode, backups not only help with lost devices but also let you easily and confidently wipe a compromised computer and get back to work quickly. Liz and Geoffrey take a look at different types of backups, including...

  11. Physical attacks to your computers and disk encryption

    Liz and Geoffrey are back with a look at physical computer security - just how much trouble could someone cause if they got access to your laptop for a few minutes? - and what sorts of problems disk encryption can and cannot solve. Also, security issues at popular social media services cause...
