ANSWER

I received an official response for the reCAPTCHA Enterprise support team:

Thanks for reaching out here. We recommend not putting a checkbox behind a score. More details are available on this here: https://cloud.google.com/recaptcha-enterprise/docs/faq#id_like_to_use_the_score_from_to_show_a_challenge_checkbox_widget_how_can_i_do_this

Not only are there concerns listed in that FAQ point about the efficacy of a checkbox widget when placed behind a score, but it also over simplifies how the checkbox widget works. We perform "adversarial challenging" on our checkbox widget (essentially, we show harder challenges to known attackers), but we're unable to do so when placed behind a score reCAPTCHA.

All of this being said, if you do wish to do it anyway, you would have to include the JS file twice.

And this is from the link posted in their email:

I'd like to use the score from reCAPTCHA Enterprise to show a challenge / checkbox widget. How can I do this?

We recommend that you do not do this. reCAPTCHA Enterprise expects to see both good and bad user behavior on implementation. If you trigger a reCAPTCHA Enterprise checkbox widget based on a reCAPTCHA Enterprise score, the checkbox widget is only being exposed to bad traffic. Due to this, the widget can have a more difficult time determining whether to show a challenge or not. This can result in issuing NO CAPTCHAs (no challenge shown at all) to fraudulent users or bots due to trouble making that differentiation.

In these cases, we recommend just using a challenge-based site key upfront (like reCAPTCHA Enterprise with a CHECKBOX Site Key) instead, but installing a SCORE Site Key on every page, as well as issuing grecaptcha.enterprise.execute to train the model, but foregoing assessments on the SCORE tokens. Essentially, this achieves the goal by training the reCAPTCHA Enterprise CHECKBOX site keys on user behavior, resulting in less challenges shown to legitimate users and more challenges to fraudulent ones.

QUESTION

proxying from containerized production react to containerized flask

Asked 2021-Jun-15 at 16:20

I am trying to proxy requests from my containerized React application to my containerized Flask application.

I was starting the application using npm start (in Docker), and I did not have any issues proxying requests. However, I learned that npm start is not a good way to proceed in production.

Following the advice here: Run a React App in a Docker Container , I am able to start my containerized production React, but now the requests are not proxied.

Within the React app, all requests are handled with axios and are formatted: "/api/v1/endpoint". It seems that others have had issues between "http://localhost:80/api/v1/endpoint" and "/api/v1/endpoint". I do not believe this is my issue, unless it arises only in the production environment.

I have also tried changing my "proxy" address in package.json to the location of the dockerized flask container, and later to the name of the docker container, but I have not been able to make either solution work.

If anyone can provide guidance on launching a containerized, production React app that proxies requests to a backend container, please advise.

I am open to using a different server, if the procedures in "Run a React App in a Docker Container" need to be updated.

How to thread a generator

Asked 2021-Jun-15 at 16:02

I have a generator object, that loads quite big amount of data and hogs the I/O of the system. The data is too big to fit into memory all at once, hence the use of generator. And I have a consumer that all of the CPU to process the data yielded by generator. It does not consume much of other resources. Is it possible to interleave these tasks using threads?

QUESTION

Security concern of using Firebase ID tokens for authentication on my custom backend

Asked 2021-Jun-15 at 15:02

I want to use firebase auth for my android and ios applications with custom backend. So I need some way of authentication for api calls from mobile apps to the backend.

I was able to find following guide in firebase documentation which suggests to sent firebase id token to my backend and validate it there with firebase Admin SDK. https://firebase.google.com/docs/auth/admin/verify-id-tokens

But this approach does not seem to be a security best practice. For example here https://auth0.com/blog/why-should-use-accesstokens-to-secure-an-api/ it is said that for API access one should use access tokens rather than id tokens.

Are there any good pattern for using firebase auth with my backend?

...

ANSWER

Answered 2021-Jun-15 at 15:02

firebaser here

Firebase itself passes the ID token with each request, and then uses that on the server to identify the user and to determine whether they're authorized to perform the operation. This is a common (I'd even say idiomatic) approach to authentication and authorization, and if there's a security risk that you've identified in it, we'd love to hear about it on https://www.google.com/about/appsecurity/

From reading the blog post it seems the author is making a distinction between authentication (the user proving their identify) and authorization (them getting access to certain resources based on that identity), but it'd probably be best to ask the author for more information on why that would preclude passing an ID token to identify the user.

You can make an internal call from the server itself, rather than from within a client. It would follow exactly the same logic (with the interval), but the code would be on the backend :)

Also if you'd like it a bit more well defined, you could use something like node-cron:

ANSWER

Answered 2021-Jun-15 at 12:20

React is a framework that is state-based - the state informs the render of the DOM. Trying to use querySelector and its equivalent won't work like you think it will.

So here's an example of this working.

We set the state to be the index of the span (initially nothing).
handleClick which is attached to the div (or would be attached to your Scale element) grabs the data id attribute from the span and adds it to the state.
This triggers the page to re-render, the spans get rebuilt, and depending on the state the selected class gets added.

There is no other DOM manipulation going on. React does all that heavy lifting for you.
