In last week’s blog we addressed the security of e-mails, which as we noted, represents a component of data-in-transit security. In case you missed the article, data-in-transit is concerned with data that is traversing a network or being temporarily stored in computer memory. Therefore, in addition to e-mail, connecting to a public network represents a serious threat to your company’s, or even your own, personal information.
For many of us, we learned to use the internet at home or in the office, locations where we felt inherently secure. But, with the recent proliferation of public Wi-Fi, such an innate feeling of security can be your enemy. To better understand the difference between information threats at home versus in public, it is beneficial to think of security controls as clothing. Sure, it’s okay to walk around at home in your underwear, but when you leave the house, it’s recommended that you put on some extra layers.
