The DiOS Backend is the main component of DiOS and is responsible for centralized data storage. It holds configuration data such as App Store account credentials (to automatically purchase apps) and status information on available iOS analysis devices. Furthermore, it archives all app binaries of recent analysis and processes analysis results reported back from the iOS devices. The backend provides a JSON-API to control the entire DiOS system and to monitor the system status. Moreover, the backend provides a web-based interface to browse the App Store and to easily schedule apps for execution to available devices.
##Dependencies:
- MongoDB
- Python
- flask, web framework
- pymongo, mongodb access layer for python
- mongokit, document based layer on top of pymongo
- flask-mongokit, flask plugin for easy mongokit integration
- requests (only required for testing)
To launch the DiOS backend component, just start the mongodb (mongod) and run backend.py.
##Install HowTo:
aptitude install mongodb
As DiOS requires up-to-date versions of some python packages, pip is preferred over apt-packages.
apt-get install build-essential python-dev python-pip
pip install flask
pip install mongokit
pip install flask-mongokit
By default, mongodb listens to local connections only. Authentication may be enabled by adding credentials to backend.cfg.
To run the DiOS backbend via apache2 the Apache module mod_wsgi is required.
apt-get install libapache2-mod-wsgi
The Apache configuration should be updates as follows (e.g., /etc/apache2/conf.d/backend.conf)
WSGIDaemonProcess AABackend user=www-data group=www-data threads=5
WSGIScriptAlias /AABackend /opt/dios/Backend/backend.wsgi
