Depending on how you are using LinkedIn, you may want to limit the amount of public exposure you have.
Those who want to market their company through the platform can create a company page, but for those who are networking with their personal professional profile, some measures can be taken to limit what is shared with the great wide world. Even though you might not have contact information in your public profile, there is a lot of potentially sensitive information that hackers and other internet-based bad guys can glean from your public LinkedIn Profile.
Listing the companies you work for or have worked for could help hackers with social engineering attacks against those companies. Listing the college you currently attend in the education section could help someone gain more information about your current whereabouts.
How to limit information in your public profile
1. Click on the profile image in the top-right corner of the LinkedIn site after you’ve logged in.
2. Click the ‘Privacy & Settings’ link from the drop down menu.
You will see a screen like this:
3. Select the ‘Privacy’ tab at the top middle of the content window, choose the ‘Edit Public Profile’ link.
4. On the Public Profile settings page, In the ‘Customize Your Public Profile’ box on the right side of the page, uncheck the boxes of the sections you wish to remove from public visibility.
Review Your Privacy Control Settings and Make Changes as Needed
If you aren’t comfortable with people seeing your activity feed or knowing that you’ve viewed their profile, consider limiting access to your feed and/or setting the ‘anonymous’ profile viewing mode. These settings are available in the ‘Privacy Controls’ section of your ‘Profile’ tab.
You will want to check this section every so often for new privacy options that may be added in the future. If LinkedIn is anything like Facebook, this section may change often.
