Code Examples​

Compliant code​

The application does not contain any method that contains sensitive information

const logIn = (req, res) => {
  if (isValidUser(req.body.user) && isValidToken(req.body.user.token)) {
    //Avoid external scripts that contain sensitive information
    res.message("Successful login");
    redirect('users/main');
  }
}

Non compliant code​

There are scripts being used that contain plain text access keys

const logIn = (req, res) => {
  if (isValidUser(req.body.user) && isValidToken(req.body.user.token)) {
    //the callScript method stores a secret key in plaint text
    res.message(callScript());
    redirect('users/main');
  }
}
