Browse LinkedIn Securely
If you're accessing LinkedIn from open Wi-Fi hotspots, your security could be at risk. Check out LinkedIn's HTTPS browsing feature: an opt-in setting that provides encrypted communications and secure identification of a network's Web server.
To turn it on, select "Settings" from the drop-down menu that appears when you hover over the link to your name in the top-right corner. In the "Profile" tab at the bottom, select "Manage Security Settings." Next, check the box and save your settings.
