Whenever you browse the web, your privacy is under constant barrage. Advertisers are trying to track every move you make, and governments around the world want in on the action as well. Getting tracked by Facebook and Google is bad enough, but knowing that the NSA has its eyes on your web traffic is more than a little worrisome. Thankfully, there are steps you can take to protect your anonymity on the web, and prevent other organizations from monitoring your browsing habits, ensuring your privacy online.
In this post, I’m going to highlight thirteen different methods you can use to keep prying eyes off of your web traffic. Some methods are more complicated than others, but if you’re serious about privacy, these tips will help you remain anonymous on the open web. Of course, internet security is a topic in and of itself, so you’re going to need to do some reading to remain thoroughly protected on all fronts. And remember, even the most careful among us are still vulnerable to imperfect technology.
Blocking third-party cookies
Third-party cookies are one of the most common methods that advertisers use to track your browsing habits. If you visit two sites using the same advertising service, rest assured that the advertiser is keeping tabs on that information. Thankfully, every major web browser offers the ability to turn off tracking cookies. Without third-party cookies, advertisers have to work much harder to monitor which pages you visit. While this is far from a panacea, it shuts down the most common vector used by advertisers to build usage profiles.
Blocking location data
Recently, many web sites have begun to use location data to offer specific services, and display local advertisements. Mapping applications obviously have legitimate reasons for gathering location data, but that same technique can be used to help identify who you are. Any legitimate browser should offer the ability to toggle on and off location data, and I recommend leaving it off completely. At the very least, demand that websites prompt you for access before gathering the data.
That said, IP-based geolocation data is incredibly trivial to acquire, so remain vigilant. If you’re browsing the web without a proxy or a VPN, you’re effectively broadcasting your IP to every server you come across, and that information can be used against you. It’s not necessarily something you have to worry about constantly, but it’s worth keeping that fact in the back of your mind if you’re criticizing your local dictator or blowing a whistle on the NSA.
Do not track
The “Do not track” HTTP header is an optional message that browsers can send to web servers. You can easily enable it in your browser’s settings, but it’s rather limited in scope. For this to work at all, the web server needs to be configured to respect this flag. There is absolutely no requirement of any kind that any website needs to obey this setting, so don’t expect widespread protection from trackers. Still, you don’t have anything to lose, so there’s no reason not to take advantage of this built-in protection.
Plug-in management
Even if your browser is configured properly to hide your identifying information, plug-ins can still be used to endanger your anonymity. If you’re serious about remaining anonymous, you should avoid running plug-ins all together. Unfortunately, that can leave a number of popular websites completely unusable. To solve this problem, I recommend a hybrid approach.
First of all, you need to configure your browser to require your approval to run any plug-in. Chrome offers this functionality in its settings, and extensions offer this capability in other browsers. Next, you need to make sure you’re running sandboxed plug-ins. While this is mostly considered a security issue, a rogue plug-in could certainly be used to gather your personal information by an organization like the NSA. Chrome can be configured to completely disallow un-sandboxed plug-ins, but it can be trickier with some other browsers. Windows users can opt to run their browsers inside of an application called Sandboxie, so even less sophisticated browsers can receive similar benefits.
