firewall Cookbook

Provides a set of primitives for managing firewalls and associated rules.

PLEASE NOTE - The resource/providers in this cookbook are under heavy development. An attempt is being made to keep the resource simple/stupid by starting with less sophisticated firewall implementations first and refactor/vet the resource definition with each successive provider.

Requirements

Platform

Ubuntu
Debian

Tested on:
* Ubuntu 10.04
* Ubuntu 11.04
* Ubuntu 11.10
* Debian 7.0

Recipes

default

The default recipe installs the ufw package, which this cookbook requires. Make sure that the firewall recipe is in the node or role run_list before any resources from this cookbook is used.

Resources/Providers

firewall

Actions

:enable: Default action enable the firewall. this will make any rules that have been defined 'active'.
:disable: disable the firewall. drop any rules and put the node in an unprotected state.

Attribute Parameters

name: name attribute. arbitrary name to uniquely identify this resource
log_level: level of verbosity the firewall should log at. valid values are: :low, :medium, :high, :full. default is :low.

Providers

Chef::Provider::FirewallUfw
- platform default: Ubuntu

Examples

# enable platform default firewall
firewall 'ufw' do
  action :enable
end

# increase logging past default of 'low'
firewall 'debug firewalls' do
  log_level :high
  action    :enable
end

firewall_rule

Actions

:allow: the rule should allow incoming traffic.
:deny: the rule should deny incoming traffic.
:reject: *Default action: the rule should reject incoming traffic.

Attribute Parameters

name: name attribute. arbitrary name to uniquely identify this firewall rule
protocol: valid values are: :udp, :tcp. default is all protocols
port: incoming port number (ie. 22 to allow inbound SSH)
ports: array of incoming port numbers (ie. [80,443] to allow inbound HTTP & HTTPS). NOTE: protocol attribute is required with ports
port_range: range of incoming port numbers (ie. 60000..61000 to allow inbound mobile-shell. NOTE: protocol attribute is required with port_range
source: ip address or subnet to filter on incoming traffic. default is 0.0.0.0/0 (ie Anywhere)
destination: ip address or subnet to filter on outgoing traffic.
dest_port: outgoing port number.
position: position to insert rule at. if not provided rule is inserted at the end of the rule list.
direction: direction of the rule. valid values are: :in, :out, default is :in
interface: interface to apply rule (ie. 'eth0').
logging: may be added to enable logging for a particular rule. valid values are: :connections, :packets. In the ufw provider, :connections logs new connections while :packets logs all packets.

Providers

Chef::Provider::FirewallRuleUfw
- platform default: Ubuntu

Examples

# open standard ssh port, enable firewall
firewall_rule 'ssh' do
  port     22
  action   :allow
  notifies :enable, 'firewall[ufw]'
end

# open standard http port to tcp traffic only; insert as first rule
firewall_rule 'http' do
  port     80
  protocol :tcp
  position 1
  action   :allow
end

# restrict port 13579 to 10.0.111.0/24 on eth0
firewall_rule 'myapplication' do
  port      13579
  source    '10.0.111.0/24'
  direction :in
  interface 'eth0'
  action    :allow
end

# open UDP ports 60000..61000 for mobile shell (mosh.mit.edu), note
# that the protocol attribute is required when using port_range
firewall_rule 'mosh' do
  protocol   :udp
  port_range 60000..61000
  action     :allow
end

# open multiple ports for http/https, note that the protocol
# attribute is required when using ports
firewall_rule 'http/https' do
  protocol :tcp
  ports    [80, 443]
  action   :allow
end

firewall 'ufw' do
  action :nothing
end
