v2.3.1 (2016-01-08)
|

|
||||
|
||||
v2.3.0 (2015-12-23)
|
||||
-------------------
|
||||
* Refactor logic so that firewall rules don't add a string rule to the firewall
|
||||
when their actions run. Just run the action once on the firewall itself. This is
|
||||
designed to prevent partial application of rules (#106)
|
||||
|
||||
* Switch to "enabled" (positive logic) instead of "disabled" (negative logic) on
|
||||

|
||||
|
||||

|
||||
-------------------
|
||||
Minor feature release.
|
||||
* Ensure ICMPv6 is open when `['firewall']['allow_established']` is set to true (the default). ICMPv6 is critical for most IPv6 operations.
|
||||
|
||||

|
||||

firewall Cookbook
|
||||
=================
|
||||
|
||||
[](http://travis-ci.org/chef-cookbooks/firewall)
|
||||
[](https://supermarket.chef.io/cookbooks/firewall)
|
||||
|
||||
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
|
||||
------------
|
||||
**Chef 12.5.x+** is required. We are currently testing against Chef 13. If you need Chef 11 support, please try pinning back to a version less than 2.0, e.g.:
|
||||
```
|
||||
depends 'firewall', '< 2.0'
|
||||
```
|
||||
|
||||
### Supported firewalls and platforms
|
||||
* UFW - Ubuntu, Debian
|
||||
* IPTables - Red Hat & CentOS, Ubuntu
|
||||
* FirewallD - Red Hat & CentOS >= 7.0 (IPv4 only support, [needs contributions/testing](https://github.com/chef-cookbooks/firewall/issues/86))
|
||||
* Windows Advanced Firewall - 2012 R2
|
||||
|
||||
Tested on:
|
||||
* Ubuntu 14.04, 16.04 with iptables, ufw
|
||||
* Debian 7, 8 with ufw
|
||||
* CentOS 6 with iptables
|
||||
* CentOS 7.1 with firewalld
|
||||
* Windows Server 2012r2 with Windows Advanced Firewall
|
||||
|
||||
By default, Ubuntu chooses ufw. To switch to iptables, set this in an attribute file:
|
||||
```
|
||||
default['firewall']['ubuntu_iptables'] = true
|
||||
```
|
||||
|
||||
By default, Red Hat & CentOS >= 7.0 chooses firewalld. To switch to iptables, set this in an attribute file:
|
||||
```
|
||||
default['firewall']['redhat7_iptables'] = true
|
||||
```
|
||||
|
||||
# Considerations that apply to all firewall providers and resources
|
||||
|
||||
This cookbook comes with two resources, firewall and firewall rule. The typical usage scenario is as follows:
|
||||
|
||||
- run the `:install` action on the `firewall` resource named 'default', which installs appropriate packages and configures services to start on boot and starts them
|
||||
|
||||
- run the `:create` action on every `firewall_rule` resource, which adds to the list of rules that should be configured on the firewall. `firewall_rule` then automatically sends a delayed notification to the `firewall['default']` resource to run the `:restart` action.
|
||||
|
||||
- run the delayed notification with action `:restart` on the `firewall` resource. if any rules are different than the last run, the provider will update the current state of the firewall rules to match the expected rules.
|
||||
|
||||
There is a fundamental mismatch between the idea of a chef action and the action that should be taken on a firewall rule. For this reason, the chef action for a firewall_rule may be `:nothing` (the rule should not be present in the firewall) or `:create` (the rule should be present in the firewall), but the action taken on a packet in a firewall (`DROP`, `ACCEPT`, etc) is denoted as a `command` parameter on the `firewall_rule` resource.
|
||||
|
||||
# iptables considerations
|
||||
|
||||
If you need to use a table other than `*filter`, the best way to do so is like so:
|
||||
```
|
||||
node.default['firewall']['iptables']['defaults'][:ruleset] = {
|
||||
'*filter' => 1,
|
||||
':INPUT DROP' => 2,
|
||||
':FORWARD DROP' => 3,
|
||||
':OUTPUT ACCEPT_FILTER' => 4,
|
||||
'COMMIT_FILTER' => 100,
|
||||
'*nat' => 101,
|
||||
':PREROUTING DROP' => 102,
|
||||
':POSTROUTING DROP' => 103,
|
||||
':OUTPUT ACCEPT_NAT' => 104,
|
||||
'COMMIT_NAT' => 200
|
||||
}
|
||||
```
|
||||
|
||||
Note -- in order to support multiple hash keys containing the same rule, anything found after the underscore will be stripped for: `:OUTPUT :INPUT :POSTROUTING :PREROUTING COMMIT`. This allows an example like the above to be reduced to just repeated lines of `COMMIT` and `:OUTPUT ACCEPT` while still avoiding duplication of other things.
|
||||
|
||||
Then it's trivial to add additional rules to the `*nat` table using the raw parameter:
|
||||
```
|
||||
firewall_rule "postroute" do
|
||||
raw "-A POSTROUTING -o eth1 -p tcp -d 172.28.128.21 -j SNAT --to-source 172.28.128.6"
|
||||
position 150
|
||||
end
|
||||
```
|
||||
|
||||
Note that any line starting with `COMMIT` will become just `COMMIT`, as hash
|
||||
keys must be unique but we need multiple commit lines.
|
||||
|
||||
# Recipes
|
||||
|
||||
### default
|
||||
The default recipe creates a firewall resource with action install.
|
||||
|
||||
### disable_firewall
|
||||
Used to disable platform specific firewall. Many clouds have their own firewall configured outside of the OS instance such as AWS Security Groups.
|
||||
|
||||

* `default['firewall']['allow_established'] = true`, set to false if you don't want a related/established default rule on iptables
|
||||
* `default['firewall']['ipv6_enabled'] = true`, set to false if you don't want IPv6 related/established default rule on iptables (this enables ICMPv6, which is required for much of IPv6 communication)
|
||||
|
||||
* `default['firewall']['firewalld']['permanent'] = false`, set to true if you want firewalld rules to be added with `--permanent` so they survive a reboot. This will be changed to `true` by default in a future major version release.

# Resources
|
||||
|
||||
### firewall
|
||||
|
||||
***NB***: The name 'default' of this resource is important as it is used for firewall_rule providers to locate the firewall resource. If you change it, you must also supply the same value to any firewall_rule resources using the `firewall_name` parameter.
|
||||
|
||||
#### Actions
|
||||
- `:install` (*default action*): Install and Enable the firewall. This will ensure the appropriate packages are installed and that any services have been started.
|
||||
- `:disable`: Disable the firewall. Drop any rules and put the node in an unprotected state. Flush all current rules. Also erase any internal state used to detect when rules should be applied.
|
||||
- `:flush`: Flush all current rules. Also erase any internal state used to detect when rules should be applied.
|
||||
- `:save`: Ensure all rules are added permanently under firewalld using `--permanent`. Not supported on ufw, iptables. You must notify this action at the end of the chef run if you want permanent firewalld rules (they are not persistent by default).
|
||||
|
||||
#### Parameters
|
||||
|
||||
- `disabled` (default to `false`): If set to true, all actions will no-op on this resource. This is a way to prevent included cookbooks from configuring a firewall.
|
||||
- `ipv6_enabled` (default to `true`): If set to false, firewall will not perform any ipv6 related work. Currently only supported in iptables.
|
||||
- `log_level`: UFW only. Level of verbosity the firewall should log at. valid values are: :low, :medium, :high, :full, :off. default is :low.
|
||||
- `rules`: This is used internally for firewall_rule resources to append their rules. You should NOT touch this value unless you plan to supply an entire firewall ruleset at once, and skip using firewall_rule resources.
|
||||
- `disabled_zone` (firewalld only): The zone to set on firewalld when the firewall should be disabled. Can be any string in symbol form, e.g. :public, :drop, etc. Defaults to `:public.`
|
||||
- `enabled_zone` (firewalld only): The zone to set on firewalld when the firewall should be enabled. Can be any string in symbol form, e.g. :public, :drop, etc. Defaults to `:drop.`
|
||||
- `package_options`: Used to pass options to the package install of firewall
|
||||
|
||||
#### Examples
|
||||
|
||||
```ruby
|
||||
# all defaults
|
||||
firewall 'default'
|
||||
|
||||
# enable platform default firewall
|
||||
firewall 'default' do
|
||||
action :install
|
||||
end
|
||||
|
||||
# increase logging past default of 'low'
|
||||
firewall 'default' do
|
||||
log_level :high
|
||||
action :install
|
||||
end
|
||||
```
|
||||
|
||||
### firewall_rule
|
||||
|
||||
#### Actions
|
||||
- `:create` (_default action_): If a firewall_rule runs this action, the rule will be recorded in a chef resource's internal state, and applied when providers automatically notify the firewall resource with action `:reload`. The notification happens automatically.
|
||||
|
||||
#### Parameters
|
||||
|
||||
- `firewall_name`: the matching firewall resource that this rule applies to. Default value: `default`
|
||||
|
||||
- `raw`: Used to pass an entire rule as a string, omitting all other parameters. This line will be directly loaded by `iptables-restore`, fed directly into `ufw` on the command line, or run using `firewall-cmd`.
|
||||
|
||||
- `description` (_default: same as rule name_): Used to provide a comment that will be included when adding the firewall rule.
|
||||
|
||||
- `include_comment` (_default: true_): Used to optionally exclude the comment in the rule.
|
||||
|
||||
- `position` (_default: 50_): **relative** position to insert rule at. Position may be any integer between 0 < n < 100 (exclusive), and more than one rule may specify the same position.
|
||||
|
||||
- `command`: What action to take on a particular packet
|
||||
|
||||
- `:allow` (_default action_): the rule should allow matching packets
|
||||
- `:deny`: the rule should deny matching packets
|
||||
- `:reject`: the rule should reject matching packets
|
||||
- `:masqerade`: Masquerade the matching packets
|
||||
- `:redirect`: Redirect the matching packets
|
||||
- `:log`: Configure logging
|
||||
|
||||
- `stateful`: a symbol or array of symbols, such as ``[:related, :established]` that will be passed to the state module in iptables or firewalld.
|
||||
|
||||
- `protocol`: `:tcp` (_default_), `:udp`, `:icmp`, `:none` or protocol number. Using protocol numbers is not supported using the ufw provider (default for debian/ubuntu systems).
|
||||
|
||||
- `direction`: For ufw, direction of the rule. valid values are: `:in` (_default_), `:out`, `:pre`, `:post`.
|
||||
|
||||
- `source` (_Default is `0.0.0.0/0` or `Anywhere`_): source ip address or subnet to filter.
|
||||
|
||||
- `source_port` (_Default is nil_): source port for filtering packets.
|
||||
|
||||
- `destination`: ip address or subnet to filter on packet destination, must be a valid IP
|
||||
|
||||
- `port` or `dest_port`: target port number (ie. 22 to allow inbound SSH), or an array of incoming port numbers (ie. [80,443] to allow inbound HTTP & HTTPS).
|
||||
|
||||
NOTE: `protocol` attribute is required with multiple ports, or a range of incoming port numbers (ie. 60000..61000 to allow inbound mobile-shell. NOTE: `protocol`, or an attribute is required with a range of ports.
|
||||
|
||||
- `interface`: (source) interface to apply rule (ie. `eth0`).
|
||||
|
||||
- `dest_interface`: interface where packets may be destined to go
|
||||
|
||||
- `redirect_port`: redirected port for rules with command `:redirect`
|
||||
|
||||
- `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.
|
||||
|
||||
#### Examples
|
||||
|
||||
```ruby
|
||||
# open standard ssh port
|
||||
firewall_rule 'ssh' do
|
||||
port 22
|
||||
command :allow
|
||||
end
|
||||
|
||||
# open standard http port to tcp traffic only; insert as first rule
|
||||
firewall_rule 'http' do
|
||||
port 80
|
||||
protocol :tcp
|
||||
position 1
|
||||
command :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'
|
||||
command :allow
|
||||
end
|
||||
|
||||
# specify a protocol number (supported on centos/redhat)
|
||||
firewall_rule 'vrrp' do
|
||||
protocol 112
|
||||
command :allow
|
||||
end
|
||||
|
||||
# use the iptables provider to specify protocol number on debian/ubuntu
|
||||
firewall_rule 'vrrp' do
|
||||
provider Chef::Provider::FirewallRuleIptables
|
||||
protocol 112
|
||||
command :allow
|
||||
end
|
||||
|
||||
# can use :raw command with UFW provider for VRRP
|
||||
firewall_rule "VRRP" do
|
||||
command :allow
|
||||
raw "allow to 224.0.0.18"
|
||||
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 60000..61000
|
||||
command :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
|
||||
port [80, 443]
|
||||
command :allow
|
||||
end
|
||||
|
||||
firewall 'default' do
|
||||
enabled false
|
||||
action :nothing
|
||||
end
|
||||
```
|
||||
|
||||
#### Providers
|
||||
|
||||
- See `libraries/z_provider_mapping.rb` for a full list of providers for each platform and version.
|
||||
|
||||
Different providers will determine the current state of the rules differently -- parsing the output of a command, maintaining the state in a file, or some other way. If the firewall is adjusted from outside of chef (non-idempotent), it's possible that chef may be caught unaware of the current state of the firewall. The best workaround is to add a `:flush` action to the firewall resource as early as possible in the chef run, if you plan to modify the firewall state outside of chef.
|
||||
|
||||
# Troubleshooting
|
||||
|
||||
To figure out what the position values are for current rules, print the hash that contains the weights:
|
||||
```
|
||||
require pp
|
||||
default_firewall = resources(:firewall, 'default')
|
||||
pp default_firewall.rules
|
||||
```
|
||||
|
||||
# Development
|
||||
This section details "quick development" steps. For a detailed explanation, see [[Contributing.md]].
|
||||
|
||||
1. Clone this repository from GitHub:
|
||||
|
||||
$ git clone git@github.com:chef-cookbooks/firewall.git
|
||||
|
||||
2. Create a git branch
|
||||
|
||||
$ git checkout -b my_bug_fix
|
||||
|
||||
3. Install dependencies:
|
||||
|
||||
$ bundle install
|
||||
|
||||
4. Make your changes/patches/fixes, committing appropiately
|
||||
5. **Write tests**
|
||||
6. Run the tests:
|
||||
- `bundle exec foodcritic -f any .`
|
||||
- `bundle exec rspec`
