SQL Server 2012: some basic questions about SQL and TLS 1.0 and 1.2

(I do not think this is a duplicate of any other TLS-related questions, such as the authoritative question about SQL Compatibility with TLS or its many duplicates, or questions about specific TLS-related problems that you might encounter with SQL CLRs or classic ASPs or ASP SSRS or whatever, this question is a little broader.)

All of our SQL servers (SQL 2012-2017) are at recent patch levels that are compatible with TLS 1.2 (see the first link above), and yet, when we disable TLS 1.0 on our SQL servers, almost all of our applications are broke (SharePoint farms, web applications, dot.net applications, PowerShell scripts, many vendor applications, heck, even some SQL jobs running in the same box it has failed).

I thought that customers already tried to negotiate the most secure encryption protocol that both the application and the SQL (TLS 1.2) support, but clearly that is not the case here.

So … what am I missing? Is there a master switch in the Windows operating system level in our application servers that never turned to indicate which applications should start using TLS 1.2? (We run Windows 2012 R2 and 2016). I think the components of MS like .Net are also updated. I know we will eventually have to see the individual applications, but I can not help thinking that something more obvious is happening here.

Also, is there any SQL query that can tell me which connection method each application tried (none versus TLS 1.0 versus TLS 1.2)? This page suggests encrypt_option since sys.dm_exec_connections, but that seems to be a boolean, not one that tells me the type (plus all my rows show FALSE, so I do not think it's correct).

abstract class: Is it a common practice or good to have basic fragments when developing an Android mobile application?

I am creating a mobile application for a software design unit that I am taking. Since I had multiple activities with similar designs for the fragments (all the implements are seen from the recycler), I created an abstract base fragment and all the other secondary fragments extend this fragment. However, since they all show different types of data, I created a set adapter method that sets the adapters for each fragment.

However, my teacher told me that for Android applications it is difficult to illustrate a design pattern because of the way their views make me feel that I have been complicating things.

The only advantage I see now is that it reduces the duplicate code.

Authentication: has been hacked by basic authentication, what to do now

I have a vps where I run an express / mongodb API with an angular 7 client (transpiled in production mode) for a school project. There is a test environment (preprod) and a production environment.

Both environments have a docker-compose.yml file that extracts the application image from a private registry of gitlab containers and has other images:

  • mongo: 4.0 (not accessible through HTTP)
  • mongo-express (similar to phpmyadmin but for mongodb, protected through basic authentication)
  • docker.elastic.co/elasticsearch/elasticsearch:7.0.0 (not accessible via HTTP)
  • docker.elastic.co/kibana/kibana:7.0.0 (accessible through HTTP, but protected through basic authentication)
  • docker.elastic.co/logstash/logstash:7.0.0 (not accessible via HTTP)
  • docker.elastic.co/apm/apm-server:7.0.0 (not accessible via HTTP)

The accessible URLs of the web server related to this application (that is, the service on the docker-compose.yml with the image of the application) are:

  • The API expresses:
    • api.example.com
    • preprod-api.example.com
  • The angular customer:
    • front.example.com
    • preprod-front.example.com
  • The mongo express
    • mongoadmin.example.com (protected through basic authentication)
    • preprod-mongoadmin.example.com (protected through basic authentication)
  • Kibana:
    • kibana.example.com (protected through basic authentication)
    • preprod-kibana.example.com (protected by basic authentication)

I also have these URLs publicly accessible but they run on other docker-compose.yml files:

  • git.example.com (gitlab instance)
  • sonar.example.com (sonarqube instance)

All the URLs I mentioned are served through HTTPS with a reverse proxy nginx and are registered in cloudflare (so AFAIK does not reveal the real IP of my web server)

Today, I have logged in mongoadmin.example.com and I saw this:

Unfortunately I did not take a screenshot of the hacked_by_unistellar collection, but basically it was a collection like

{
"collectionName": name
"restote": "To restore this collection, send an email to unistellar@yandex.com"
}

So I did it docker-compose window down -v (It's not a big problem since there was no data to restore anyway). And it changed the basic authentication password from 32 strong characters to 100 characters one (both generated through lastpass where lowercase characters, capital letters, numbers and special characters are accepted)

However, I am still wondering about some things:

  • I doubt he owns the domain. yandex.com, then, why would you want me to send you an email to this address?
  • How could he know that the basic authentication password was "strong", at least I guess it was something like (& 5M /% b * 2ZkQCfvNYU & HMjgNQ5Yz # FnF9)
  • What steps should I take to prevent this from happening in the future? I changed all other basic authentication passwords, since I could have entered and not modify anything.
  • In the worst case, if the attacker finds a way to log in to the server, he can only do things in the container of the docker window he entered, right?

PD: I myself find this question a little awkward, if you have clues about how I should reduce it, I would gladly do it.

And let me know if I should add my nginx configuration, docker-compose.yml files or some other information.

Also, I did not know what labels to use for these questions

javascript – Basic installation of React using the tag

I'm doing the Bucky Robert tutorial (The New Boston) on React (hyperlink in the code below).

I'm stuck at the beginning, just trying to install / load React with the tag instead of using local files. I receive two error messages:

  1. TypeError: t (…). The object is not defined[Learn More] browser.min.js: 8: 31612
  2. SyntaxError: Expected expression, it was obtained & # 39; <& # 39;[Learn More] test.html: 19: 24

I bet my problem is pretty basic, but I spent a lot of time trying to figure out what's going on.

Basically, I just want to know what would be the error-free version of my code to be able to do the tutorials.
