1. Testing Node Security by @jmortegac NOV 18-19 · 2016
2. Agenda  Introduction nodejS security  Npm security packages  Node Goat project  Tools
3. nodeJS introduction  JavaScript in the backend  Built on Chrome´s Javascript runtime(V8)  NodeJs is based on event loop  Designed to be asynchronous  Single Thread  Concurrent requests.
4. Security updates
5. Security updates
6. Find nodeJS vulnerabilities  http://cve.mitre.org/find/
7. Last vulnerabilities  https://nodesecurity.io/advisories
8. NPM modules install
9. Npm security packages  Helmet  express-session / cookie-session  csurf  express-validator  bcrypt-node  express-enforces-ssl
10. Security HTTP Headers  Strict-Transport-Security  X-Frame-Options  X-XSS-Protection  X-Content-Type-Options  Content-Security-Policy
11. Helmet module  https://www.npmjs.com/package/helmet
12. Helmet module  https://github.com/helmetjs/helmet
13. Helmet module  CSPContent-Security-Policy header  hidePoweredBydeletes X-Powered-by header  Hpkpprotection MITM  Hstsforces https connections  noCachedesactive client cache  Frameguardprotection clickjacking  xssFilterprotection XSS
14. Helmet module
15. Check headers security  http://cyh.herokuapp.com/cyh  https://securityheaders.io/
16. Express versions  https://www.shodan.io/search?query=express
17. Disable x-powered-by  Avoid framework fingerprinting
18. Disable x-powered-by  Use Helmet and use “hide-powered-by” plugin
19. Sessions management  https://www.npmjs.com/package/cookie-session  secure  httpOnly  domain  path  expires
20. httpOnly & secure:true
21. Delete cookies from cache browser // Set cache control header to eliminate cookies from cache app.use(function (req, res, next) { res.header('Cache-Control', 'no-cache="Set-Cookie, Set-Cookie2"'); next(); });
22. XSS attacks  An attacker can exploit XSS vulnerability to:  Steal session cookies/Sesion hijacking  Redirect user to malicious sites  Defacing and content manipulation  Cross Site Request forgery
23. https://www.npmjs.com/package/csurf
24. CSRF <form action="/process" method="POST"> <input type="hidden" name="_csrf" value="{{csrfToken}}"> <button type="submit">Submit</button> </form> app.use(function (request, response, next) { response.locals.csrftoken = request.csrfToken(); next(); });
25. CSRF
26. Filter/sanitize user input  Avoid XSS attacks  https://www.npmjs.com/package/sanitizer  Module express-validator  https://www.npmjs.com/package/express-validator
27. Validator
28. Validator
29. Validator
30. Validator with reg exp
31. Regular expressions  https://www.npmjs.com/package/safe-regex  Detect vulnerable regular expressions that can cause DoS
32. NodeJS Crypto  http://nodejs.org/api/crypto.html  Use require(‘crypto’) to access this module  The crypto module requires OpenSSL require("crypto") .createHash("sha1") //algorithm .update(“cOdEmOtiOn") //text .digest("hex"); //hexadecimal result
33. Bcrypt-node  https://github.com/kelektiv/node.bcrypt.js
34. Bcrypt-node
35. Bcrypt-node
36. Bcrypt-node
37. Building a secure HTTPS server
38. Building a secure HTTPS server  https://www.npmjs.com/package/https-redirect-server  https://www.npmjs.com/package/express-enforces-ssl  Redirect all traffic to https and a secure port
39. Building a secure HTTPS server
40. Building a secure HTTPS server var helmet = require("helmet"); var ms = require("ms"); app.use(helmet.hsts({ maxAge: ms("1 year"), includeSubdomains: true }));  Send hsts header for all requests
41. Node Goat  http://nodegoat.herokuapp.com/tutorial
42. Node Goat  https://github.com/OWASP/NodeGoat
43. EVAL()
44. EVAL() on github
45. EVAL() ATTACKS res.end(require('fs').readdirSync('.').toString()) res.end(require('fs').readdirSync('..').toString())
46. Insecure Direct Object References  Use session instead of request param  var userId = req.session.userId;
47. Tools  NSP  Require Safe  David  KrakenJS / Lusca middleware  Retire  snyk.io
48. NSP  https://github.com/nodesecurity/nsp  npm install -g nsp  Analyze package.json  nsp check --output summary
49. NSP with Grunt  npm install –g grunt-nsp-package
50. Nsp execution
51. Nsp execution
52. Project dependences  https://david-dm.org/
53. Project dependences
54. Project dependences  npm install –g david
