If you try to reach the same website from another browser and that website opens without any error, then an HSTS setting is affecting your web browser. For example, Google Chrome can display: “Privacy error: Your connection is not private” (NET::ERR_CERT_AUTHORITY_INVALID). Yet, the HSTS implementation can cause some hiccups from time to time by displaying HSTS errors in browsers. Mostly, the creation of HSTS has been accepted well among developers and regular users because of its ability to strengthening online security measures and reducing the risk of corrupting your data or website being hacked. So, HSTS policy is implemented, which prevents this attack by communicating to the web browsers that only HTTPS connections should be placed.

Initially, HSTS was created as a response to Moxie Marlinspike introduced vulnerability discussed in 2009 BlackHat Federal talk titled “New Tricks for Defeating SSL in Practice.” In that one vulnerability, that HSTS helps in defending is the one illustrated by Marlinspike’s SSLStrip tool.Įssentially that mentioned tool SSLStrip tool attacks secure HTTPS connections and turns it back into unsecured HTTP ones. Also, prevent common tools like Firesheep to steal cookie-based login credentials. In return, it helps in avoiding attacks such as cookie hijacking or downgrade attacks. HSTS (HTTP Strict Transport Security), is one of the web security policy which enforces web browsers to interact with websites only through secured HTTPS connection (and not HTTP).
