Performance

The following configuration settings are used for caching.

KeyDefaultDescription

com.cerebro.domino.controlCenter.cacheMaxLoadPeriodInMonths

Web Apps

IFrame Security

Web apps in Domino are served in HTML inline frames, also known as “iframes”. To improve iframe security, a “sandbox” attribute can be set for iframe elements. When this attribute is set, extra security restrictions are applied to the iframes serving web apps in Domino, like blocking cross-origin requests, form submissions, script executions, and much more.

In Domino, this “sandbox” attribute can be toggled with the ShortLived.iFrameSecurityEnabled feature flag. Setting this flag to “TRUE” will apply the sandbox attribute to the iframe and apply the extra security restrictions. If the flag is set to “FALSE”, no security restrictions will be applied to the iframe. By default, in Domino 4.4.1 the ShortLived.iFrameSecurityEnabled flag is set to FALSE.

Important

Content Security Policies

A content security policy allows Domino web apps to access specific, whitelisted external resources. Any request made to non-whitelisted external resources, however, will be blocked.

In Domino, you can toggle this feature with the EnableContentSecurityPolicyforApps feature flag. Setting this flag to “TRUE” will block requests to all non-whitelisted resources and allow requests to whitelisted resources. Setting this flag to “FALSE” will allow all requests to resources (that is, no blocking of any kind). By default, in Domino 4.4.1 the EnableContentSecurityPolicyforApps is set to FALSE.

The keys and default values associated with this feature flag are listed in the table below.

Key

Default

Description

com.cerebro.domino.apps.contentSecurityPolicy.whiteListAppHost

true

Whitelist the app’s own host URL for all resource types. This can be toggled to false for an even more stringent security policy. For example, to prevent internal attacks by disabling all JavaScript in web apps, you can set this flag to false and com.cerebro.domino.apps.contentSecurityPolicy.whiteListedScriptSrcList to none or the empty string.

com.cerebro.domino.apps.contentSecurityPolicy.whiteListedImageSrcList

data:

Allows images to be inserted directly into a webapp using a data: URL. This allows Domino apps to include images in the app’s HTML without loading the image from an outside resource. Learn more about data: URLs here: Mozilla - Data URLs.

com.cerebro.domino.apps.contentSecurityPolicy.whiteListedScriptSrcList

cdnjs.cloudflare.com/ajax/libs/jquery/3.1.0/jquery.js cdn.plot.ly/plotly-latest.min.js 'unsafe-eval' 'unsafe-inline'

Whitelists the URLs of the scripts that the demo Apps in the quick-start project load to display their interactive charts. It also allows an app to define scripts in HTML using the <script> tag. Also allows JavaScript to create more JavaScript as the app runs using the built-in JavaScript function eval.

com.cerebro.domino.apps.contentSecurityPolicy.whiteListedStyleSrcList

'unsafe-inline'

Allows apps to define their own styles with <style>, javascript: URLs, and inline <script> elements.

com.cerebro.domino.apps.contentSecurityPolicy.whiteListedConnectSrcList

ws:

Allows the app to use WebSockets, which use URLs that begin with ws:, to communicate with other resources.

To whitelist a resource:

  1. Go to Configuration Management (that is, Central Config) in your Domino admin settings.

  2. Click Add Record.

  3. Set the key to com.cerebro.domino.apps.contentSecurityPolicy.whiteListedConnectSrcList.

  4. Set the value to ws: followed by the URL of the resource you’d like to whitelist (that is, ws: https://foobar.buz.bax/). You must work with your team to figure out which URLs have to be whitelisted. For more details, see: Identify Resources to Whitelist.

  5. Save the record and restart Domino services.

IFrame Security in combination with Content Security Policies

In Domino 4.4.1, the ShortLived.iFrameSecurityEnabled and EnableContentSecurityPolicyforApps feature flags coexist. The matrix below describes the blocking behavior for requests based on both feature flags.

Important

The IFrame feature flag will be deprecated in future versions of Domino. Domino recommends implementing web app security using content security policies instead.

ShortLived.iFrameSecurityEnabled = FALSEShortLived.iFrameSecurityEnabled = TRUE

EnableContent SecurityPolicyForApps = FALSE

No blocking occurs. All requests to external resources are allowed.

All requests from web apps to external resources are blocked.

EnableContent SecurityPolicyForApps = TRUE

Only requests to whitelisted external resources are allowed. All other requests to external resources are blocked.

All requests from web apps to external resources are blocked.
