==== Noncompliant code example

[source,javascript,diff-id=1,diff-type=noncompliant]
----
const https = require('node:https');

let options = {
  hostname: 'www.example.com',
  port: 443,
  path: '/',
  method: 'GET',
  checkServerIdentity: function() {}, // Noncompliant
  secureProtocol: 'TLSv1_2_method'
};

let req = https.request(options, (res) => {
  res.on('data', (d) => {
    process.stdout.write(d);
  });
});
----

[source,javascript,diff-id=2,diff-type=noncompliant]
----
const tls = require('node:tls');

let options = {
  checkServerIdentity: function() {}, // Noncompliant
  secureProtocol: 'TLSv1_2_method'
};

let socket = tls.connect(443, "www.example.com", options, () => {
  process.stdin.pipe(socket);
  process.stdin.resume();
});

==== Compliant solution

  method: 'GET',
  secureProtocol: 'TLSv1_2_method'
};

let req = https.request(options, (res) => {
  res.on('data', (d) => {
    process.stdout.write(d);
  });
});
----

const tls = require('node:tls');

let options = {
  secureProtocol: 'TLSv1_2_method'
};

let socket = tls.connect(443, "www.example.com", options, () => {
