“Mr. Coca Cola” -or- Hackers never sleep: Protecting Data at rest

Data at rest is stored data that isn’t currently being used or transferred.

For instance, at the Coca Cola factory: when Mr. Coca Cola sends all the “cola artists” (I’m assuming he calls them that) home for the evening, the secret recipe won’t be needed for at least another 8 hours.

Mr. Ebenezer Coca-Cola (artist’s rendering)

So of course, he just takes the piece of paper with the secret recipe on it, and sticks it to his personal office vending machine with a refrigerator magnet, and heads home to watch “Fired Up,” right? Wrong!

First, “Fired Up” went off the air years ago, lasted only two seasons, only aired briefly in syndication and is not available on Netflix. Not even star Sharon Lawrence has any copies. It’s gone gone.

Second, Mr. Coca Cola needs the secret recipe to remain a secret. During the day, he can personally add the ingredients for Coca Cola to the giant mixing vat located in earthquake-proof bedrock five miles below the factory floor. But at night. At night he needs to store the recipe safely, while it is Data at rest. That’s because a) it’s always night somewhere b) hackers never sleep.

So what he really does is quite simple: he encrypts the file that contains the recipe. Only Mr. Coca Cola and the President of the United States know the password to decrypt it. The recipe is safe until tomorrow morning.

The end.

Next time…protecting Data in motion.

LastPass: stuff you need to know

Now that you have a LastPass account…

Wait…you do have a LastPass account, don’t you? No? That’s ok, read this first, then come back.

Now that you have a LastPass account, there are a few important things to do (and to avoid) to make sure you get the most out of it while keeping the security of your passwords intact.

Here’s your initial checklist (explanations of how to do each of these follows this list):

  • Set an idle timeout in the browsers you use.
  • Set LastPass to log you out when you close your browsers.
  • Lock your computer when you leave it.

Set an idle timeout in the browsers you use, and have LastPass log out when browsers are closed:
This will make sure that you don’t stay logged on to LastPass indefinitely, which is a security risk. You’ll want to follow these steps on your computer and any computer you use LastPass on.

Click on the LastPass icon in your web browser: (Internet Explorer, Firefox, Chrome, Safari, etc:
lp-extension-button

Select Preferences:

Check the two security boxes, with the values below, then click Save.lp-browser-close-idle-timeout

Lock your computer when you’re away from it.
This is pretty easy. On Windows, press the windows key + L
lock
This will lock the screen so that you have to enter your password upon returning to your computer.

On Mac it’s, um…let me Google that.
[…Google-ing…]
On a Mac it’s CTRL + SHIFT + EJECT, or in picture form:

ctrl-shift-eject

To recap, do these three things:

1 & 2) Tell LastPass to log out when you close your browser and Set an idle log out time: 

 

3) Lock your computer when you’re away from it.
windows = lock

mac = ctrl-shift-eject

Awesome. Thanks for doing that. Remember, you can’t spell “Security” without “U”!

Your friend and password manager,
LastPass

Meet your new password manager, LastPass!

Hi, I’m LastPass!

lastpass-icon
I’m a red square with an asterisk in it! Or maybe I’m a snowflake on a red trampoline! I live in your browser and on your phone!

Some call me “The Last Password You’ll Have to Remember,” and I’d have to say: that’s pretty accurate!* My job is to make it easy to secure your passwords. You only have to remember one (sufficiently strong)** unique master password.

How I work, in a nutshell:

Instead of typing in your username and password to sites you visit (or having your web browser remember them, which is convenient but generally very insecure), you log into LastPass (that’s me!), and I enter your username and password for you.

Or, in video form:

In my next post, I’ll explain how to install me on your computer. It’s pretty easy, not to mention “required by NTC’s Information Security Policy.” Which is really another way of saying, “It’s fun!”

Your Friend,

LastPass

*   (There may be a password or two you’ll have to keep in your head, but the majority of passwords  you can “set and forget”)

** How strong is a “sufficiently strong” master password? For NTC, it means your password must be at least 8 characters, and have at least one letter and one number, and it must be unique, as in you are not using it for anything but your LastPass master password.
