>                 Key: SPARK-22188
>                 URL:
>             Project: Spark
>          Issue Type: Improvement
>          Components: Spark Core
>    Affects Versions: 2.2.0
>            Reporter: Krishna Pandey
>            Assignee: Apache Spark
>            Priority: Minor
>              Labels: security
> Below HTTP Response headers can be added to improve security.
> The HTTP *Strict-Transport-Security* response header (often abbreviated as HSTS) is a
security feature that lets a web site tell browsers that it should only be communicated with
using HTTPS, instead of using HTTP.
> *Note:* The Strict-Transport-Security header is ignored by the browser when your site
is accessed using HTTP; this is because an attacker may intercept HTTP connections and inject
the header or remove it. When your site is accessed over HTTPS with no certificate errors,
the browser knows your site is HTTPS capable and will honor the Strict-Transport-Security
> *An example scenario*
> You log into a free WiFi access point at an airport and start surfing the web, visiting
your online banking service to check your balance and pay a couple of bills. Unfortunately,
the access point you're using is actually a hacker's laptop, and they're intercepting your
original HTTP request and redirecting you to a clone of your bank's site instead of the real
thing. Now your private data is exposed to the hacker.
> Strict Transport Security resolves this problem; as long as you've accessed your bank's
web site once using HTTPS, and the bank's web site uses Strict Transport Security, your browser
will know to automatically use only HTTPS, which prevents hackers from performing this sort
of man-in-the-middle attack.
> *Syntax:*
> Strict-Transport-Security: max-age=<expire-time>
> Strict-Transport-Security: max-age=<expire-time>; includeSubDomains
> Strict-Transport-Security: max-age=<expire-time>; preload

> The HTTP *X-XSS-Protection* response header is a feature of Internet Explorer, Chrome
and Safari that stops pages from loading when they detect reflected cross-site scripting (XSS)
> *Syntax:*
> X-XSS-Protection: 0
> X-XSS-Protection: 1
> X-XSS-Protection: 1; mode=block
> X-XSS-Protection: 1; report=<reporting-uri>

> The HTTP *X-Content-Type-Options* response header is used to protect against MIME sniffing
vulnerabilities. These vulnerabilities can occur when a website allows users to upload content
to a website however the user disguises a particular file type as something else. This can
give them the opportunity to perform cross-site scripting and compromise the website. Read
