If you wish to deploy in AWS, use this previous release.
Concrete Relay implementation using Threatscore | Cyberprotect as a third-party Cyber Threat Intelligence service provider.
The Relay itself is just a simple application written in Python that can be easily packaged and deployed. This relay is now Cisco Hosted and no longer requires AWS Lambda.
- We need an application that will translate API requests from SecureX Threat Response to the third-party integration, and vice versa.
- We need an application that can be completely self contained within a virtualized container using Docker.
Open the code folder in your terminal.
cd code
If you want to test the application you have to install a couple of extra dependencies from the Pipfile file:
pip install --no-cache-dir --upgrade pipenv && pipenv install --dev
You can perform two kinds of testing:
-
Run static code analysis checking for any semantic discrepancies and PEP 8 compliance:
flake8 .
-
Run the suite of unit tests and measure the code coverage:
coverage run --source api/ -m pytest --verbose tests/unit/ && coverage report
If you want to test the live Lambda you may use any HTTP client (e.g. Postman),
just make sure to send requests to your Lambda's URL
.
NOTE. If you need input data for testing purposes you can use data from the observables.json file.
In order to build the application, we need to use a Dockerfile
.
- Open a terminal. Build the container image using the
docker build
command.
docker build -t tr-05-cyberprotect .
- Once the container is built, and an image is successfully created, start your container using the
docker run
command and specify the name of the image we have just created. By default, the container will listen for HTTP requests using port 9090.
docker run -dp 9090:9090 --name tr-05-cyberprotect tr-05-cyberprotect
- Watch the container logs to ensure it starts correctly.
docker logs tr-05-cyberprotect
- Once the container has started correctly, open your web browser to http://localhost:9090. You should see a response from the container.
curl http://localhost:9090
This application was developed and tested under Python version 3.9.
-
POST /health
- Checks that the service is available at the moment.
-
POST /deliberate/observables
- Accepts a list of observables and filters out unsupported ones.
- Makes a series of requests to the underlying external service to query for some cyber threat intelligence data on each supported observable.
- Maps the fetched data into appropriate CTIM entities.
- Returns a list per each of the following CTIM entities (if any extracted):
Verdict
.
-
POST /observe/observables
- Accepts a list of observables and filters out unsupported ones.
- Makes a series of requests to the underlying external service to query for some cyber threat intelligence data on each supported observable.
- Maps the fetched data into appropriate CTIM entities.
- Returns a list per each of the following CTIM entities (if any extracted):
Verdict
,Judgement
.
-
POST /version
- Returns the current version of the application.
ip
ipv6
domain
Each response from the Threatscore Cyberprotect API for the supported observables generates the following CTIM entities:
Verdict
is based on.scores[]
Judgement
is based on.scores[].details[].
