[NodeCongress2021] The Security Toolbox For Node – Milecia McGregor
Fortifying Node.js bastions against pervasive threats demands a curated arsenal, blending vigilance with automation. Milecia McGregor, senior software engineer at Conducto, assembles this kit, dissecting OWASP’s top perils and arming attendees with battle-tested countermeasures. From dependency audits to server sentinels, her compendium ensures sprints proceed apace while vulnerabilities wane.
Milecia commences with reconnaissance: npm audit scans repos for exploits, flagging severity via exit codes integrable to CI. Snyk elevates this, fusing vuln databases with fix PRs, while Dependabot automates updates—proactive bulwarks against supply-chain snares like left-pad debacles.
Safeguarding Dependencies and Inputs
Injections top OWASP’s docket; Milecia prescribes parameterized queries via Knex or Sequelize, thwarting SQLi. XSS bows to sanitized outputs—DOMPurify scrubs payloads—while CSRF yields to csurf’s tokens. Auth falters sans salting; bcrypt hashes credentials, JWTs secure sessions with HS256.
Broken access? Role-based guards via Passport middleware enforce hierarchies. Sensitive leaks? dotenv .gitignore guards env vars; helmet configures headers, quelling MIME sniffing and clickjacking.
Validation anchors integrity: Joi schemas parse inputs, rejecting malformations; validator.js tackles emails, phones—eschewing bespoke parsers.
Encrypting Flows and Throttling Threats
Data en route merits crypto-js’s AES, obfuscating intercepts. Servers crave HTTPS—certbot automates Let’s Encrypt—rate-limit via express-rate-limit, capping barrages at 100/min/IP. DDoS? Cloudflare proxies absorb volleys.
Milecia extols reuse: helmet’s quick wins, Kali Linux’s adversarial lens. Her takeaways—leverage extant libs, preempt breaches, probe attacker tactics—empower swift fortifications, harmonizing security with agility.
