Etherpad plugin to bring in helmet. Helmet provides security for express. See the Helmet docs for it's capabilities. Helmet also brings iFrame embed capabilities into Etherpad.
Basic usage is simple, just install the plugin.
Just use the same settings Helmet exposes for CSP.
"ep_helmet":{
"csp":{
"directives": {
"objectSrc": ["'none'"],
"upgradeInsecureRequests": true,
"workerSrc": false
}
}
}
The above CSP will need to be polished over time https://ponyfoo.com/articles/content-security-policy-in-express-apps is a good write up that needs to be referred to and supported
Frameguard can be used to set X-Frame-Options which is useful if you embed Etherpad in an iFrame.
"ep_helmet":{
"frameguard":{
"action": "allow-from",
"domain": "https://DOMAINIFRAMEWILLBEHOSTEDIN.com"
}
}
