The Content Security Policy (CSP) feature mitigates a broad class of content injection vulnerabilities, such as cross-site scripting (XSS), by providing policy directives to compliant browsers. This feature is enabled by default. You can reconfigure the policy directives by adding entries to locked.properties.
CSP Properties for Horizon 2312 and Earlier
| Property | Value Type | Primary Default | Other Defaults |
|---|---|---|---|
| enableCSP | true false | true | n/a |

CSP Properties for Horizon 2406 and Later
Note: Starting with Horizon 2412, portal is excluded from the automatic application of a Content Security Policy (CSP) header to servlet responses. Instead, the portal servlet now applies its own CSP header. To customize the portal CSP header see Configure the Horizon 8 Web Portal Page for End Users for details.

Example CSP Properties
You can add CSP properties to the `locked.properties` file, for example:enableCSP = true
content-security-policy = default-src 'self';script-src 'self' 'unsafe-inline' 'unsafe-eval' data:;style-src 'self'
'unsafe-inline';font-src 'self' data:
content-security-policy-admin = default-src 'self';script-src 'self' 'unsafe-inline' 'unsafe-eval' data:;style-src 'self'
'unsafe-inline';font-src 'self' data:;img-src 'self' data:;connect-src 'self' https:
content-security-policy-rest = default-src 'self';script-src 'self' 'unsafe-inline' 'unsafe-eval' data:;style-src 'self'
'unsafe-inline';font-src 'self' data:;img-src 'self' data: blob:;media-src 'self' blob:;connect-src 'self' wss:;frame-src
'self' blob:;child-src 'self' blob:;object-src 'self' blob:
x-content-type-options = nosniff
x-frame-options = deny
x-frame-options-rest = sameorigin
