With multiple layers of protection, Chromebooks do an excellent job of protecting your files and personal information. You'll soon be safer when Chrome OS adds USBGuard to block access to the USB port while the device's screen is locked. A USB stick can be used in a Rubber Ducky attack to steal data or malware if you turn your back or leave your device unattended. In addition to the built-in security features, there are a few ways to protect your Chromebook.
Sharing your Chromebook with friends and acquaintances requires familiarization with guest mode. This will allow someone to use your Chromebook without touching their Google Account. Not only does this prevent access to your data and files, it also prevents your settings from getting corrupted. A guest's browsing history, cookies, bookmarks, and downloads are deleted when they're done with your Chromebook and you leave guest mode and sign back in to your account.
Guest mode should be enabled by default. You can go to Settings and in the section People click to manage other people . Verify that Enable guest browsing is enabled.
To start guest mode, log out of your account (the quickest way is to press Ctrl-Shift-Q twice) and then click Search as Guest at the bottom of the screen.
Close the lid of your Chromebook and the device goes into sleep mode. Open it again and your Chromebook will pop up. This is definitely easy. However, if you're worried that others will be accessing your sleeping Chromebook while you're away (or sleeping yourself), you can choose to lock the device when it sleeps, and require a password when it wakes up.
Go to Settings and click Screen Lock and Login in the section People . Next, enter your password and switch to . Show lock screen when you wake up from sleep . If you have a long, complicated password that you do not need to re-enter each time you wake up your Chromebook, select PIN or password and then click the Set up PIN button and Choose a six-digit (or more) PIN that you can use to unlock your Chromebook instead of your password.
HTTPS Everywhere for All
This Chrome extension created by Chrome Frontier Foundation and the Tor project uses HTTPS version of a site, if available. By default, many sites use unencrypted HTTP, and HTTPS Everywhere requests the HTTPS version. If using the extension breaks a site you want to access, you can disable it by clicking the button. And for the super-security conscious, you can select a check box to block all unencrypted sites.
