A quick guide to deploying some Security Docker Containers.

Install

Grab a copy of Docker for your platform here: https://www.docker.com/community-edition#/download Follow the installation guide and tune the docker system to run with as much memory and CPU as you're willing to feed to it.

Docker Containers I find useful for general security tasks:

Local Debian instance: debian:latest

Metasploit: remnux/metasploit

Superset serve on nginx with prefix
Hi.
Here is the content of my nginx config file :

proxy_set_header Host $host;
proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for;
proxy_set_header X-Script-Name /analytics;
proxy_pass http://YOUR_SERVER_NAME:8088;
#YOUR_SERVER_NAME is localhost if both nginx and superset run on same server

Fine-tuning a Keras model. Updated to the Keras 2.0 API.
'''This script goes along the blog post
"Building powerful image classification models using very little data"
from blog.keras.io.
It uses data that can be downloaded at:
https://www.kaggle.com/c/dogs-vs-cats/data
In our setup, we:
- created a data/ folder
- created train/ and validation/ subfolders inside data/
- created cats/ and dogs/ subfolders inside train/ and validation/
- put the cat pictures index 0-999 in data/train/cats
