This repository contains the sample code to go along with Cisco DevNet Learning Labs covering security topics. During the setup steps of the labs, you'll be asked to clone this repository down to your workstation to get started.
- Go to https://developer.cisco.com/learning/tracks/devnet-express-security#dne-security-verify and login or register if you're not registered.
- Follow the instructions in the lab. The lab environment offers a step-by-step path to configure and run the examples of this repository.
You may either do the labs in the virtual environment offered by Cisco or configure your own environment on your desktop.
You need a PC or MAC with the following software:
- Anyconnect VPN client : either the package provided by Cisco for Windows environment or the free client available on Linux platform, openconnect http://ubuntuhandbook.org/index.php/2014/11/connect-cisco-anyconnect-vpn-ubuntu/.
- RDP client to connect to windows, either the RDP client embarked in any windows OS or a free alternative such as Remmina https://remmina.org/how-to-install-remmina/. The connection parameters are provided in the lab environment.
Python is required to run the sample scripts.
You have to install Python 3.6. We suggest that you work in a virtual environment to work with Python. If you want to know more about virtual env, this document is an excellent introduction http://christopher5106.github.io/python/2017/10/12/python-packages-and-their-managers-apt-yum-easy_install-pip-virtualenv-conda.html. The lab explains how to install virtual-env. You can work with Miniconda as an alternative. To install Miniconda, follow the official instructions here: https://conda.io/miniconda.html.
You use Postman to test REST API calls in a graphical environment. To install Postman, follow the official instructions here: https://learning.getpostman.com/docs/postman/launching_postman/installation_and_updates/.
You should run the following commands on Linux to create a virtual environment with Conda:
$conda create --name cisco python=3.6
$source activate cisco
and you're done!
Contributions are welcome, and we are glad to review changes through pull requests. See contributing.md for details.
The goal of these learning labs is to ensure a 'hands-on' learning approach rather than just theory or instructions.

Within this repository are several files and folders covering different topics and labs. This table provides details on what each is used for, and which labs they correspond to.
| File / Folder | Description |
|---|---|
env_lab.py |
A Python file containing lab infrastructure details for routers, switches and appliances leveraged in the different labs. This file provides a centralized Python import that is used in other code samples to retrieve IPs, usernames, and passwords for connections |
env_user.template |
Similar to env_lab.py, this is a template for end users to copy within their own code repo as env_user.py where they can provide unique details for their own accounts. For example, their Webex Teams (formerly Cisco Spark) authentication token. Not all labs require this file, if one does it will be specified in setup. |
requirements.txt |
Global Python requirements file containing the requirements for all labs within this repository. Each folder also contains a local requirements.txt file. |
intro-python-code/ |
Sample code and exercises for the Python Fundamentals Learning Labs Pulled in through a file copy in November 2018. Note that the submodule tracks with the master branch, but solutions are on the solution branch in the original CiscoDevNet/intro-python-code repository. |
intro-rest-api/ |
Sample code and exercises for the REST API Fundamentals Learning Labs Pulled in through a file copy in November 2018. |
intro-umbrella/ |
Sample code and exercises for the Introduction to Cisco Umbrella Learning Labs (Publishing Soon) |
verify/ |
A series of verification scripts primarily used during DevNet Express events to ensure the workshop environment is fully operational. |
dev/ |
Resources and information for building code samples and labs. |
requirements-dev.txt |
Python requirements file containing requirements only needed if developing new code samples. |
Note: These code samples are also leveraged during DevNet Express events. If you are one of these events, your event proctors and hosts will walk you through event setup and verification steps as part of agenda.
Note: the
mission-datadirectory contains the answsers in JSON files. This is as last resort only when the attendee is not able to solve it. Make sure that the attendees don't use this to "cheat".
