# Tools



## Web Framework Hardening

- [Helmet](https://www.npmjs.com/package/helmet) - Helmet helps you secure your Express apps by setting various HTTP headers.

- [blankie](https://github.com/nlf/blankie) - CSP plugin for [hapi](https://github.com/hapijs/hapi).



## Static Code Analysis

- [eslint-plugin-security](https://www.npmjs.com/package/eslint-plugin-security) - ESLint rules for Node Security. This project will help identify potential security hotspots, but finds a lot of false positives which need triage by a human.

- [safe-regex](https://www.npmjs.com/package/safe-regex) - detect potentially catastrophic exponential-time regular expressions by limiting the star height to 1.

- [vuln-regex-detector](https://www.npmjs.com/package/vuln-regex-detector) - This module lets you check a regex for vulnerability. In JavaScript, regular expressions (regexes) can be "vulnerable": susceptible to catastrophic backtracking. If your application is used on the client side, this can be a performance issue. On the server side, this can expose you to Regular Expression Denial of Service (REDOS).

- [git-secrets](https://github.com/awslabs/git-secrets) - Prevents you from committing secrets and credentials into git repositories.

- [DevSkim](https://github.com/Microsoft/DevSkim) - DevSkim is a set of IDE plugins and rules that provide security "linting" capabilities. Also has support for CLI so it can be integrated into CI/CD pipeline.

- [ban-sensitive-files](https://github.com/bahmutov/ban-sensitive-files) - Checks filenames to be committed against a library of filename rules to prevent storing sensitive files in Git. Checks some files for sensitive contents (for example authToken inside .npmrc file).

- [NodeJSScan](https://ajinabraham.github.io/NodeJsScan/) - A static security code scanner for Node.js applications. Including neat UI that can point where the issue is and how to fix it.

- [Nsecure](https://github.com/ES-Community/nsecure) - Node.js CLI that allow you to deeply analyze the dependency tree of a given npm package or a directory.

- [Trust But Verify](https://github.com/verifynpm/tbv) - TBV compares an npm package with its source repository to ensure the resulting artifact is the same.

- [lockfile-lint](https://github.com/lirantal/lockfile-lint) - lint lockfiles for improved security and trust policies to keep clean from malicious package injection and other insecure configurations.

- [pkgsign](https://github.com/RedpointGames/pkgsign) - A CLI tool for signing and verifying npm and yarn packages.



## Input Validation & Output Encoding

- [node-esapi](https://www.npmjs.com/package/node-esapi) - node-esapi is a minimal port of the ESAPI4JS (Enterprise Security API for JavaScript) encoder.

- [escape-html](https://www.npmjs.com/package/escape-html) - Escape string for use in HTML.

- [js-string-escape](https://www.npmjs.com/package/js-string-escape) - Escape any string to be a valid JavaScript string literal between double quotes or single quotes.

- [validator](https://github.com/chriso/validator.js) - An npm library of string validators and sanitizers.

- [xss-filters](https://www.npmjs.com/package/xss-filters) - Just sufficient output filtering to prevent XSS!



## Secure Composition

- [pug-plugin-trusted-types](https://www.npmjs.com/package/pug-plugin-trusted-types) - Pug template plugin makes it easy to securely compose HTML from untrusted inputs and provides CSP & CSRF [automagic](https://www.npmjs.com/package/pug-plugin-trusted-types#hdr-automagic).

- [safesql](https://www.npmjs.com/package/safesql) - A tagged template (mysql\`...\`) that understands [Postgres](https://www.npmjs.com/package/safesql#pg)'s & [MySQL](https://www.npmjs.com/package/safesql#mysql)'s query grammar to prevent [SQL injection](https://www.oreilly.com/library/view/securing-node-applications/9781491982426/ch01.html#idm140399946848800).

- [sh-template-tag](https://www.npmjs.com/package/sh-template-tag) - A tagged template (sh\`...\`) that understands Bash syntax so prevents [shell injection](https://www.oreilly.com/library/view/securing-node-applications/9781491982426/ch01.html#idm140399951358480).



## CSRF

- [csurf](https://www.npmjs.com/package/csurf) - Node.js CSRF protection middleware.

- [crumb](https://github.com/hapijs/crumb) - CSRF crumb generation and validation for [hapi](https://github.com/hapijs/hapi).



## Vulnerabilities and Security Advisories

- [npq](https://github.com/lirantal/npq) - Safely install packages with npm or yarn by auditing them as part of your install process.

- [snyk](https://www.npmjs.com/package/snyk) - Snyk helps you find, fix and monitor known vulnerabilities in Node.js npm, Ruby and Java dependencies, both on an ad hoc basis and as part of your CI (Build) system.

- [npm-audit-resolver](https://www.npmjs.com/package/npm-audit-resolver) - Manage npm-audit results, including options to ignore specific issues in clear and auditable way.

- [gammaray](https://github.com/nearform/gammaray) - Runs a security audit based on your package.json using the [Node.js Security Working Group vulnerability data](https://github.com/nodejs/security-wg/).

- [patch-package](https://www.npmjs.com/package/patch-package) - Allows app authors to create fixes for npm dependencies (in node_modules) without forking or waiting for merged PRs, by creating and applying patches.



## Security Hardening

- [express-limiter](https://www.npmjs.com/package/express-limiter) - Rate limiting middleware for Express applications built on redis.

- [limits](https://www.npmjs.com/package/limits) - Simple express/connect middleware to set limit to upload size, set request timeout etc.

- [rate-limiter-flexible](https://www.npmjs.com/package/rate-limiter-flexible) - Fast, flexible and friendly rate limiter by key and protection from DDoS and brute force attacks in process Memory, Cluster, Redis, MongoDb, MySQL, PostgreSQL at any scale. Express and Koa examples included.
