== Sensitive Code Example

https://www.npmjs.com/package/serve-static[Express.js serve-static] middleware:


----
let serveStatic = require("serve-static");
let app = express();
let serveStaticMiddleware = serveStatic('public', { 'index': false, 'dotfiles': 'allow'});   // Sensitive
app.use(serveStaticMiddleware);
----

== Compliant Solution

https://www.npmjs.com/package/serve-static[Express.js serve-static] middleware:


----
let serveStatic = require("serve-static");
let app = express();
let serveStaticMiddleware = serveStatic('public', { 'index': false, 'dotfiles': 'ignore'});   // Compliant: ignore or deny are recommended values
let serveStaticDefault = serveStatic('public', { 'index': false});   // Compliant: by default, "dotfiles" (file or directory that begins with a dot) are not served (with the exception that files within a directory that begins with a dot are not ignored), see serve-static module documentation
app.use(serveStaticMiddleware);
