hood

Cover your head.

Security headers middleware for connect or express.

Further readings on middlewares can be found here

Usage

var hood = require('hood');
app.use(hood());

This will setup sane defaults for most apps. You can also pass options to configure each middleware.

app.use(hood({
  csp: "default-src 'unsafe-inline'",
  hsts: false // pass false to disable a middlware 
}));

Each middleware is also available individually.

csp

app.use(hood.csp());
app.use(hood.csp({
  policy: {
    'default-src': ['self', 'unsafe-inline']
  }
}));
app.use(hood.csp("default-src 'self';"));
 
// to use Report-Only 
app.use(hood.csp({
  policy: somePolicy,
  reportOnly: true
}))
app.use(hood.csp(policyStr, true));

hsts

Only applies header if request is secure. Checks req.connection.encrypted and req.connection.proxySecure.

app.use(hood.hsts());
app.use(hood.hsts({
  maxAge: 1000, // seconds 
  includeSubdomains: true // default false 
}));
app.use(hood.hsts(1000, true));

xframe

app.use(hood.xframe()) // DENY 
app.use(hood.xframe({
  sameOrigin: true
}));
app.use(hood.xframe({
  allow: 'http://example.domain'
}));
app.use(hood.xframe('SAMEORIGIN'));
app.use(hood.xframe('ALLOW-FROM http://example.domain'));

nosniff

app.use(hood.nosniff());

header

A convenience method when you need to add arbitrary headers to all requests.

app.use(hood.header('x-foo', 'bar'));
app.use(hood.header({
  'x-foo': 'bar',
  'x-baz': 'quux'
}));
