Why blocking ads and enforcing HTTPS is a good thing.

Over the last few days, there have been multiple announcements about the Chrome browser and its new features. From an integrated ad-blocker to trust warnings on websites with no HTTPS encryption. But what is all the fuzz really about?

Is the Chrome team trying to remove my income from the ad campaigns on my website? In short: No, they don’t! Google Chrome’s new feature targets advertisement, redirecting the user’s focus away from the page’s content. If your website uses normal ad displays, they won’t be affected by the new features in any way. So-called “tab-under” are examples of advertisements that will be blocked, starting with the release of Google Chrome 64. They represent all kinds of ads, which open up new tabs without asking the user and redirect them to this new tab. While a user can only close the newly opened tab to get back to the original site, these advertisement tabs either won’t open at all, or the user will get a UI dialogue to ask for permission. Besides “tab-under,” also animated and intrusive ads will be blocked.

Okay, so I can still rely on my ad-campaign income, but what about enforcing SSL encryption on my website?

In 2014, Google started to improve the ranking of websites that provide SSL encryption compared to pages that do not. Since then, the percentage of encrypted website traffic through the Chrome browser has increased to 68 percent on windows and 78 percent on mac. Starting in July 2018, Chrome will mark websites as “not secure” if they do not provide any SSL encryption. But what does it mean to be “not secure”?

Well, depending on your web application’s features, being “not secure” might not mean anything. Still, it can also increase new users’ mistrust of using your application. A simple static website with no interaction options might not benefit from an SSL certificate. On the other hand, non-encrypted traffic can be monitored and is especially interesting for attackers if it contains user-provided data. This includes passwords, credit card information, and other valuable information. Even though there might not be a technical benefit in having encryption on a static website, people will still be more likely to use it if they don’t see the “not secure” label. Suppose you handle confidential user input and don’t provide encryption already. Shame on you! Now is the time to change it!

I can’t afford an SSL certificate! The last time I checked, they were like 100$ a year!

First, it is essential to know that there are multiple SSL certificates, and the registrar signs every certificate. Therefore, some are more trustworthy than others, and the prices differ from very cheap to very expensive.

But wait! There are also free ones even the smallest website can afford. Projects like Let’s Encrypt grew rapidly over the last few years and have proven that it is possible to provide free SSL certificates to more than 100 million domains. As a technically experienced user, obtaining and installing a valid certificate within a few minutes is easy. Many web hosters also provide easy one-click options to automatically create a valid Let’s Encrypt certificate during account creation, and are even easier to use. In summary, a valid SSL Certificate only costs me a few minutes and not a single dollar.

So, I click install, and I am done?

Basically, that’s it! More giant corporations probably won’t go for a free certificate but want to increase the trust level further. Higher tiers of SSL Certificates also show the company name within the certificate and verify certain information before being provided to the company. A simple free certificate mostly doesn’t verify any user or company information and only validates the domain name.

Now that Google Chrome says my application is “Secure,” am I done?

The traffic between clients and your application is now encrypted and cannot be easily monitored and analyzed, but there is more!

There are multiple ways of encrypting the data, so-called Cipher Suites. For most certificates, the certificate owner can choose which suites to use and overwrite the default values, which are not always the best. In addition, you can choose the ciphers, disable certain legacy features that contain vulnerabilities, and enable others to miss them by default.

We gathered a list of possible improvements for configuring your SSL certificate in this blog post. If you are interested in validating your existing Certificate’s security, we also provide an extensive test in our free package of the Crashtest Security Suite. After just a few minutes, we list all the findings and provide you with the information you need to improve.

Let’s not only encrypt but also do it right!
