Ensnare

Ensnare is packaged as a gem plugin for Ruby on Rails and was developed to allow configuring and deploying a basic malicious behavior detection and response scheme in less than ten minutes.

Ensnare uses a combination of Honey Traps to entice malicious users, and a configurable suite of Trap Responses to confuse, allude, delay, or stop an attacker.

Install

Add the gem to your project's Gemfile:

    gem 'ensnare', :git => 'git@github.com:ahoernecke/Ensnare.git'

Install the gem:

    bundle install

Run the migrations for Ensnare:

    rake ensnare:install:migrations
    rake db:migrate

Enable parameter tampering for your application by changing the mass_assignment_sanitizer:

    vi config/environments/<ENVIRONMENT>.rb

Set config.active_record.mass_assignment_sanitizer to logger:

    config.active_record.mass_assignment_sanitizer = :logger 

Enable Ensnare in your application_controller.rb file:

    vi app/controllers/application_controller.rb

Append the following filter below protect_from_forgery in your application_controller.rb file:

    before_filter :ensnare

Add the following to the end of your routes.rb file:

    mount Ensnare::Engine => "/ensnare", :as => "ensnare_engine" 
    match "*_", :to => "ensnare::violations#routing_error"

Create an Ensnare config file:

    rails g ensnare:install

Take a look at the example ensnare.rb file:

    vi config/initializes/ensnare.rb

After you start your application, take a look at the dashboard:

http://your-application.com/ensnare/dashboard/violations

In order to access the dashboard, this step needs to be performed.

To prevent unnecessary users from accessing the dashboard, add the following to the config/initalizers/ensnare.rb file:

  config.dashboard_user_method = :current_user
  config.dashboard_authorization_method = :admin?

NOTE: you need to have a method defined to check if the user is the admin.
