How do I add HTTP Strict Transport Security HSTS to my website?

How do I add HTTP Strict Transport Security (HSTS) to my website? If you are running Windows Server 2019, open the Internet Information Services (IIS) Manager and click on the website. Click on HSTS. Check Enable and set the Max-Age to 31536000 (1 year).

Can you bypass HSTS?

Unlike other HTTPS errors, HSTS-related errors cannot be bypassed. This is because the browser has received explicit instructions from the browser not to allow anything but a secure connection.

What happens if HSTS is not enabled?

Sometimes, an IT security scan might report that your site is “missing HSTS” or “HTTP Strict Transport Security” headers. If you encounter this error, then your site isn't using HSTS, which means your HTTPS redirects may be putting your visitors at risk. This is classed as a medium-risk vulnerability.

How do I know if HSTS is enabled?

There are a couple easy ways to check if the HSTS is working on your WordPress site. You can launch Google Chrome Devtools, click into the “Network” tab and look at the headers tab. As you can see below on our Kinsta website the HSTS value: “strict-transport-security: max-age=31536000” is being applied.

Is HSTS same as HTTPS?

The HTTP Strict-Transport-Security response header (often abbreviated as HSTS) informs browsers that the site should only be accessed using HTTPS, and that any future attempts to access it using HTTP should automatically be converted to HTTPS.

What is HSTS header in web config?

HTTP Strict Transport Security (HSTS) is an optional security enhancement that is specified by a web application through the use of a special response header. Once a supported browser receives this header, it prevents any communication to the specified domain from being sent over HTTP and instead, sends it over HTTPS.

Does HSTS header include subdomains?

The HSTS policy includes all subdomains, with a long max-age , and a preload flag to indicate that the domain owner consents to preloading. The website redirects from HTTP to HTTPS, at least on the root domain.

What is HSTS middleware?

HSTS stands for HTTP Strict Transport Security. It is a method used by websites to declare that they should only be accessed using a secure connection (HTTPS). If a website declares an HSTS policy, the browser must refuse all HTTP connections and prevent users from accepting insecure SSL certificates.

Do subdomains affect CORS?

CORS is not allowing subdomains, so you need to specify them in your server configuration.

Are subdomains covered by SSL?

SSL certificates can secure main domains, subdomains, and multi-level domains.

Do I need separate SSL for each subdomain?

Yes, in general, a different SSL would be required for each subdomain, because each subdomain is considered a separate domain. However, there are wildcard SSL certificates available on the SSL market.
