ACM.124: Configuring a site identify for our batch job authentication move

This can be a continuation of my sequence on automating cybersecurity metrics.

In my final put up, I seemed on the Oktapus assaults in 2022 and we thought-about some mechanisms to forestall an analogous assault on our personal system that we’re constructing.

It seems to be like we will want an internet site to facilitate the authentication workflow I have been describing, which often begins with a site identify. As I discussed within the final put up that we wish to make it straightforward for customers to recollect the URL of our batch job administration workflow, we wish to create one thing easy and memorable.

I am considering of utilizing the next area, which is a subdomain of 2ndsightlab.com (my prime stage area).

https://batch.2ndsightlab.com

Registering a prime stage area identify

To make use of that area, I first have to register the highest stage area identify (2ndsightlab.com) which I’ve already finished. The area I discussed above is a subdomain. I can create many subdomains for 2ndsightlab.com. Probably the most widespread subdomains is www (in my case, www.2ndsightlab.com), however lately most individuals ditch www and go on to the top-level area (TLD) with out www.

If you wish to register a site identify, you are able to do it on AWS:

You can even register a site by means of a third-party area identify registrar like Google Domains:

Why would you wish to use one area identify registrar over one other?

One of many advantages of utilizing AWS for every thing is which you can get all of your help in a single place. The good thing about registering a site with a third-party area identify registrar is that Amazon just isn’t accountable for your whole stack from prime to backside. The opposite motive you would possibly use one registrar over one other is price, though cheaper registrars might not present the help you want in case your area is one way or the other transferred by means of unauthorized means.

Additionally, some registrars will supply TLDs that others don’t. For instance, one registrar presents domains ending in .biz or .dev and one other presents .cloud, .weblog, or .information.

Selecting a Prime Degree Area (TLD)

Please notice that selecting an odd TLD might trigger your area to be blocked by some safety techniques. I wrote about using odd TLDs by malware right here:

Since most professional domains do not finish in these bizarre extensions, some DNS directors will reject requests to resolve them, thus hunting down some potential malware. When you select one among these bizarre domains, it could look nice, however requests to go to your web site could also be blocked.

There are a lot of different advertising and mental property concerns that I will not go into right here. Earlier than selecting a site identify, you could wish to seek the advice of with an mental property lawyer and advertising particular person or not less than perform some research on-line so you do not select a site identify you later remorse.

Utilizing a site identify in AWS that’s registered elsewhere

If you have already got a site identify registered someplace, you need to use it on AWS. You simply have to configure the area identify accurately on the DNS registrar. Verify the documentation the place you registered your area identify to learn how to do that. Usually, you will log in and supply “identify servers” that inform the Web how one can get to the server or system that hosts your web site, software, or web page.

That is how you’d configure Google Domains to make use of AWS DNS servers:

The next directions clarify how one can create a hosted zone on Route 53.

When you create this hosted zone, you need to use that data to configure the DNS servers at Google Domains (or no matter area identify registrar you are utilizing).

Transfer or switch a site identify

You could or might not wish to transfer a site you registered elsewhere to AWS. These directions clarify how one can configure DNS for an present area identify with minimal service interruptions.

Be aware which you can skip the steps to maneuver the area to AWS, however if you wish to switch the area to handle it multi functional place, you may. Please notice that in the event you transfer your area in the course of its annual renewal cycle, you’ll pay overlapping charges. Additionally, you will wish to test the price of the actual area you are altering, and ensure AWS helps the TLD.

Whenever you switch a site, you will have to unlock it at your registrar to permit the switch and observe the directions at each your present registrar and AWS to facilitate the switch. There could also be some downtime relying on how your registrar handles the switch.

Transfer a site between AWS accounts

You can even switch domains between AWS accounts. Maybe you have created domains through the years and wish to consolidate them right into a single account for simpler administration. These directions will assist.

The significance of securing your area identify

Too many individuals do not perceive the significance of securing and defending their domains. Typically individuals join with internet hosting suppliers who register the area identify for the shopper. The shopper might not perceive that he has no entry to or management over her personal area identify. Be sure you register your individual area identify and know who can switch it or change configuration settings.

Listed below are a number of the the explanation why you ought to be cautious with area identify registrations and settings:

• If somebody can get your area identify, they will arrange a google workspace in your area:

• Conversely, somebody would possibly take away required TXT information for companies you have got approved by means of your DNS configuration companies might fail.
• If somebody can change the place e mail goes in your area, they could have entry to reset passwords and take over cloud accounts.
• One other DNS-related assault I mentioned at RSA 2020 is known as subdomain acquisition. You will wish to make certain your subdomains level to correct sources.
• You additionally don’t need individuals to set unauthorized subdomains ao authorize undesirable companies by accessing your DNS settings.

Now you perceive why I at all times ask shoppers throughout a cloud safety evaluation who has entry to the DNS settings for his or her domains. In a Google Cloud Platform (GCP) safety evaluation, the brand new CISO and the employees concerned within the evaluation had no concept the place the area was registered or who had entry to it. In fact, they instantly contacted the corporate executives and addressed that challenge once I requested about it.

Blocking DNS settings in AWS

You’ll be able to lock down DNS configurations in AWS by proscribing entry to Route 53 utilizing IAM and group insurance policies. Nevertheless, you could want sure individuals to have the ability to configure some features of DNS, however not be capable to delete and deregister their domains.

One technique could be to place all of your domains in a single account that’s accessible by restricted people who find themselves chargeable for area identify configurations. It might even require customers to make use of a separate login when dealing with domains and lock management of these logins.

Then create NS information in separate accounts to deal with subdomains and website hosting. I’ve used that technique for pen testing sources and subdomains related to cloud safety courses. We’ll cowl how one can automate that in a future put up, however first we’ll think about governance for DNS information.

Observe for updates.
