There has been a steady increase in the number of applications that have switched to using HTTPS instead of HTTP for communication. Even sites that have no sensitive information or authentication mechanisms. Using HTTPS provides authentication and a secure channel to transmit data between client and server. The authentication verifies that you are communicating with the organization you thought you were. This secure transmission is meant to stop other parties from being able to read or manipulate the user’s traffic. For non-sensitive applications, it is that ability to manipulate the traffic that we are trying to protect against.
Mozilla announced that the next version of FireFox, Firefox 51, will be changing how it presents the lock icon to represent security issues with the site. Traditionally, there would be a green lock icon for secure sites and no lock icon for sites that use HTTP. The new changes will introduce a grey lock icon with a red slash through it when a site is using HTTP and collects passwords. In addition, there will be a note indicating that “Logins entered on this page could be compromised.”
Mozilla also hints at some additional changes on the roadmap. In particular, a potential indicator on the password field that will alert the user that the account details are insecure and may be compromised. It will be interesting to see how this feature will be implemented, especially if the browser will inject code into the application code. This could raise some concerns for many others out there.
Back in September, 2016, Google announced that Chrome was making similar changes that would take effect in January. I did a podcast on this which is included here.
Google is going further than just passwords and including credit card number fields. There wasn’t much mentioned for FireFox about anything other than passwords. In both browsers, changes should be available soon. Help spread the word about the new changes so your users, your friends, and your family know what the new indicator really means.
You may be surprised at the number, or type of sites that may be affected by this. There are many forums and other community sites that get created without using HTTPS for transmission. This may be because the site owner doesn’t realize the benefits of using HTTPS. They may also not think that the site contains sensitive information, so why add the overhead. However, many of these sites do require you to create an account and log in with a password. Unfortunately, many people re-use passwords so na attacker getting that forum password may have also just gotten your password for other sites. Not to mention, they could impersonate you on the specific site.
In the absence of sensitive or account information, using HTTPS provides protection from traffic manipulation. Even rising a corporate landing page, an attacker on the same network could inject malicious code into the response to attempt malicious activity on your system.
What are your thoughts? Are you for the browsers making these types of changes? Do you think it is an overreach? If so, why? Share your thoughts on twitter or join our slack channel to join the conversation (send me an email for an invite).
