Fi Security

Application security module for Node.js Express applications.

Installing

npm install --save fi-security

Usage

Initialization

You must call it with your Express' application instance, to attach the routes, and a configuration object. It's important to initialize the Express' session before you configure Fi Security:

var session = require('express-session');
var security = require('fi-security');
var express = require('express');

var app = express();

app.use(session());

security(app, config);

/* And now your routes... */
app.get('/', (req, res, next) => {
  //...
});

Configuration

The configuration Object must be pretty much like a Fi Aegis configuration Object, since this module is based on it.

• debug: This option can be a Function to log with or a Boolean. If true it'll use console.log.
• csrf: Same as Fi Aegis with the addition of the exclude property:
  • exclude: An array of routes with their method(s) and path(s) to be excluded from CSRF checks:
    • method: A single POST, PUT or DELETE method or an array of them. Empty means ALL.
    • path: A valid Express route path.
• csp: Same as Fi Aegis.
• xframe: Same as Fi Aegis.
• hsts: Same as Fi Aegis.
• nosniff: Same as Fi Aegis.
• xssProtection: Same as Fi Aegis.
• p3p: Same as Fi Aegis.

Example configuration

{
  debug: true,

  p3p: 'ABCDEF',

  csrf: {
    exclude: [{
      method: 'POST',
      path: '/no-csrf'
    }, {
      path: '/api/external'
    }]
  },

  xframe: 'DENY',

  xssProtection: {
    enabled: true
  },

  csp: {
    reportUri: 'https://example.com',
    policy: {
      'default-src': "'self'"
    }
  },

  hsts: {
    includeSubDomains: true,
    maxAge: 31536000
  },

  nosniff: true
}

Using with AngularJS

Just add this to your Fi Security configuration:

//...

csrf: {
  angular: true
  //...
}

//...
