Class ContentSecurityPolicyManager

java.lang.Object

com.jalios.jcms.security.ContentSecurityPolicyManager

All Implemented Interfaces:

JcmsConstants, JaliosConstants, JPropertiesListener

public class ContentSecurityPolicyManager
extends java.lang.Object
implements JcmsConstants, JPropertiesListener

Content Security Policy implementation in JCMS.

The following properties can be defined to configure this implementation :

 # Is CSP enabled for this site ?
 # default is false
 channel.security.csp.enabled: true
 
 
 # space or coma seperated list of jsp (servlet path) excluded from CSP processing
 # use with care, you should not have to exclude anything !!!
 # default is empty
 channel.security.csp.excluded-path:
 
 
 # List of HTTP header names to be used to output the header corresponding to "Content-Security-Policy" specification.
 # Eg "Content-Security-Policy", "X-Content-Security-Policy", "X-WebKit-CSP" to broaden browser support.
 # default is "Content-Security-Policy"
 channel.security.csp.csp-header-names: Content-Security-Policy
 
 # List of HTTP header names to be used to output the header corresponding to "Content-Security-Policy-Report-Only" specification.
 # Eg "Content-Security-Policy-Report-Only", "X-Content-Security-Policy-Report-Only", "X-WebKit-CSP-Report-Only" to broaden browser support.
 # default is "Content-Security-Policy-Report-Only"
 channel.security.csp.csp-report-only-header-names: Content-Security-Policy-Report-Only
 
 
 # Java Format string used to output the "Content-Security-Policy" HTTP Header(s) value
 # %1s can be used to output a nonce generated for reach request  
 # default is empty as a fine tuning is required for each site
 channel.security.csp.csp-header: 
 
 # Java Format string used to output the "Content-Security-Policy-Report-Only" HTTP Header(s) value
 # %1s can be used to output a nonce generated for reach request  
 # default is empty as a fine tuning is required for each site

Method Detail

getInstance

public static ContentSecurityPolicyManager getInstance()

Retrieve the singleton instance of this manager.

Returns:

the ContentSecurityPolicyManager singleton

propertiesChange

public void propertiesChange(JProperties properties)

Description copied from interface: JPropertiesListener

Invoked after properties have been modified in JCMS and save on disk.

You cannot alter the value received in parameters.

Specified by:

propertiesChange in interface JPropertiesListener

Parameters:

properties - the properties which have been modified (may not contain all JCMS properties)

configure

public static void configure(javax.servlet.http.HttpServletRequest request,
             javax.servlet.http.HttpServletResponse response)

Initialize the Content Security Policy for the specified request/response.

• Build a nonce value for use in HTML tags
• Add appropriate HTTP headers to the response according to site configuration

This method is reentrant : process will only performed once per request even if invoked several times.

Parameters:

request - the current HttpServletRequest, must not be null

response - the current HttpServletResponse, must not be null

Since:

jcms-9.0

getNonce

public static java.lang.String getNonce(javax.servlet.http.HttpServletRequest request)

Retrieve the Content Security Policy nonce value to use in HTML scripts tags.

Parameters:

request - the current request in which nonce was initialized by configure(HttpServletRequest, HttpServletResponse)

Returns:

a nonce or an empty string if CSP was not initialized, never return null

Since:

9.0
