aws_waf_rule resource

Use the aws_waf_rule Chef InSpec audit resource to test the properties of a single AWS WAF (web application firewall) rule.

The AWS::WAF::Rule resource type creates a firewall rule that identifies the web requests that you want to allow, block, or count.

For additional information, including details on parameters and properties, see the AWS documentation on the AWS::WAF::Rule resource type.

Install

This resource is available in the Chef InSpec AWS resource pack.

For information on configuring your AWS environment for Chef InSpec and creating an InSpec profile that uses the InSpec AWS resource pack, see the Chef InSpec documentation on the AWS cloud platform.

Ensure that a WAF rule exists.

describe aws_waf_rule(rule_id: 'RULE_ID') do
  it { should exist }
end

rule_id: A unique identifier for a rule.
name: The name of the rule.
metric_name: The name of the metrics for this rule.
predicates_negated: False if the AWS WAF rule will allow, block, or count requests based on the settings in the specified ByteMatchSet, IPSet, SqlInjectionMatchSet, XssMatchSet, RegexMatchSet, GeoMatchSet, or SizeConstraintSet object.
predicates_type: The type of predicate in a rule, such as ByteMatch or IPSet.
predicates_data_id: A unique identifier for a predicate in a rule, such as ByteMatchSetId or IPSetId.

Ensure a rule is available.

describe aws_waf_rule(rule_id: 'RULE_ID') do
  its('rule_id') { should eq 'RULE_ID' }
end

Ensure a rule name is available.

describe aws_waf_rule(rule_id: 'RULE_ID') do
    its('name') { should eq 'RULE_ID_NAME' }
end

Ensure a metric name type is METRIC_NAME.

describe aws_waf_rule(rule_id: 'RULE_ID') do
    its('metric_name') { should include 'METRIC_NAME' }
end

Verify the type of data ID should be ‘DATA_ID’.

describe aws_waf_rule(rule_id: 'RULE_ID') do
    its('predicates_data_id') { should include 'DATA_ID' }
end

end

Use should_not to test the entity does not exist.

describe aws_waf_rule(rule_id: 'RULE_ID') do
  it { should_not exist }
end

Use should to check if the entity is available.
