OWASP Secure Headers Project OWASPThe following contains a list of HTTP response headers related to security. Response Headers. HSBC Premier has a range of daytoday benefits to offer including a rewards programme, a dedicated Relationship Manager or worldwide support. Find out more. Browser Test. This page will test your browsers ability to render Java, JavaScript, CSS, VBScript, ActiveX, Cascading Style Sheets, and IFRAME. HTTP Strict Transport Security HSTSHTTP Strict Transport Security HSTS is a web security policy mechanism which helps to protect websites against protocol downgrade attacks and cookie hijacking. It allows web servers to declare that web browsers or other complying user agents should only interact with it using secure HTTPS connections, and never via the insecure HTTP protocol. HSTS is an IETF standards track protocol and is specified in RFC 6. A server implements an HSTS policy by supplying a header Strict Transport Security over an HTTPS connection HSTS headers over HTTP are ignored. SECONDS. The time, in seconds, that the browser should remember that this site is only to be accessed using HTTPS. Sub. Domains. If this optional parameter is specified, this rule applies to all of the sites subdomains as well. Example. Strict Transport Security max age3. Sub. Domains. References. Public Key Pinning Extension for HTTP HPKPHTTP Public Key Pinning HPKP is a security mechanism which allows HTTPS websites to resist impersonation by attackers using mis issued or otherwise fraudulent certificates. For example, sometimes attackers can compromise certificate authorities, and then can mis issue certificates for a web origin. The HTTPS web server serves a list of public key hashes, and on subsequent connections clients expect that server to use one or more of those public keys in its certificate chain.

Connect with friends, family and other people you know. Share photos and videos, send messages and get updates. Deploying HPKP safely will require operational and organizational maturity due to the risk that hosts may make themselves unavailable by pinning to a set of public key hashes that becomes invalid. With care, host operators can greatly reduce the risk of man in the middle MITM attacks and other false authentication problems for their users without incurring undue risk.

Some browsers might allow other hashing algorithms than SHA 2. SECONDS. The time, in seconds, that the browser should remember that this site is only to be accessed using one of the pinned keys. Sub.

X Frame Options response header improve the protection of web applications against Clickjacking. It declares a policy communicated from a host to the client browser on whether the browser must not display the transmitted content in frames of other web pages. No rendering within a frame. No rendering if origin mismatch. DOMAIN. Allows rendering if framed by frame loaded from DOMAIN. Example. X Frame Options deny. References. This header enables the Cross site scripting XSS filter in your browser. Filter disabled. Filter enabled. If a cross site scripting attack is detected, in order to stop the attack, the browser will sanitize the page. Filter enabled. Rather than sanitize the page, when a XSS attack is detected, the browser will prevent rendering of the page. YOURDOMAINyourreportURI. Filter enabled. The browser will sanitize the page and report the violation. This is a Chromium function utilizing CSP violation reports to send details to a URI of your choice. Example. X XSS Protection 1 modeblock. References. Setting this header will prevent the browser from interpreting files as something else than declared by the content type in the HTTP headers. Will prevent the browser from MIME sniffing a response away from the declared content type. Example. X Content Type Options nosniff. References. Content Security Policy CSP requires careful tuning and precise definition of the policy. If enabled, CSP has significant impact on the way browser renders pages e. Java. Script disabled by default and must be explicitly allowed in policy. CSP prevents a wide range of attacks, including Cross site scripting and other cross site injections. Values Directive. Define the base uri for relative uri. Define loading policy for all resources type in case of a resource type dedicated directive is not defined fallback. Define which scripts the protected resource can execute. Define from where the protected resource can load plugins. Define which styles CSS the user applies to the protected resource. Define from where the protected resource can load images. Define from where the protected resource can load video and audio. Deprecated and replaced by child src. Define from where the protected resource can embed frames. Define from where the protected resource can embed frames. Define from where the protected resource can be embedded in frames. Define from where the protected resource can load fonts. Define which URIs the protected resource can load using script interfaces. Define from where the protected resource can load manifest. Define which URIs can be used as the action of HTML form elements. Specifies an HTML sandbox policy that the user agent applies to the protected resource. Define script execution by requiring the presence of the specified nonce on script elements. Define the set of plugins that can be invoked by the protected resource by limiting the types of resources that can be embedded. Instructs a user agent to activate or deactivate any heuristics used to filter or block reflected cross site scripting attacks, equivalent to the effects of the non standard X XSS Protection header. Prevent user agent from loading mixed content. Instructs user agent to download insecure resources using HTTPS. Define information user agent must send in Referer header. Specifies a URI to which the user agent sends reports about policy violation. Specifies a group defined in Report To header to which the user agent sends reports about policy violation. Example. Content Security Policy script src selfReferences. X Permitted Cross Domain Policies. A cross domain policy file is an XML document that grants a web client, such as Adobe Flash Player or Adobe Acrobat though not necessarily limited to these, permission to handle data across domains. When clients request content hosted on a particular source domain and that content make requests directed towards a domain other than its own, the remote domain needs to host a cross domain policy file that grants access to the source domain, allowing the client to continue the transaction. Normally a meta policy is declared in the master policy file, but for those who cant write to the root directory, they can also declare a meta policy using the X Permitted Cross Domain Policies HTTP response header. No policy files are allowed anywhere on the target server, including this master policy file. Only this master policy file is allowed. HTTPHTTPS only Only policy files served with Content Type textx cross domain policy are allowed. FTP only Only policy files whose file names are crossdomain. URLs ending in crossdomain. All policy files on this target domain are allowed.
