Documentation
A single rule, which you can use in a WebACL or RuleGroup to identify web requests that you want to allow, block, or count. Each rule includes one top-level Statement that WAF uses to identify matching web requests, and parameters that govern how WAF handles them.
See: newRule
smart constructor.

Instances
:: Text | |
-> Natural | |
-> Statement | |
-> VisibilityConfig | |
-> Rule |
Create a value of Rule
with all optional fields omitted.
Use generic-lens or optics to modify other optional fields.
The following record fields are available, with the corresponding lenses provided for backwards compatibility:
$sel:action:Rule'
, rule_action
- The action that WAF should take on a web request when it matches the
rule statement. Settings at the web ACL level can override the rule
action setting.
This is used only for rules whose statements do not reference a rule
group. Rule statements that reference a rule group include
RuleGroupReferenceStatement
and ManagedRuleGroupStatement
.
You must specify either this Action
setting or the rule
OverrideAction
setting, but not both:
- If the rule statement does not reference a rule group, use this rule action setting and not the rule override action setting.
- If the rule statement references a rule group, use the override action setting and not this action setting.
$sel:captchaConfig:Rule'
, rule_captchaConfig
- Specifies how WAF should handle CAPTCHA
evaluations. If you don't
specify this, WAF uses the CAPTCHA
configuration that's defined for
the web ACL.
$sel:challengeConfig:Rule'
, rule_challengeConfig
- Specifies how WAF should handle Challenge
evaluations. If you don't
specify this, WAF uses the challenge configuration that's defined for
the web ACL.
$sel:overrideAction:Rule'
, rule_overrideAction
- The action to use in the place of the action that results from the rule
group evaluation. Set the override action to none to leave the result of
the rule group alone. Set it to count to override the result to count
only.
You can only use this for rule statements that reference a rule group,
like RuleGroupReferenceStatement
and ManagedRuleGroupStatement
.
This option is usually set to none. It does not affect how the rules in
the rule group are evaluated. If you want the rules in the rule group to
only count matches, do not use this and instead use the rule action
override option, with Count
action, in your rule group reference
statement settings.
$sel:ruleLabels:Rule'
, rule_ruleLabels
- Labels to apply to web requests that match the rule match statement. WAF
applies fully qualified labels to matching web requests. A fully
qualified label is the concatenation of a label namespace and a rule
label. The rule's rule group or web ACL defines the label namespace.
Rules that run after this rule in the web ACL can match against these
labels using a LabelMatchStatement
.
For each label, provide a case-sensitive string containing optional namespaces and a label name, according to the following guidelines:
- Separate each component of the label with a colon.
- Each namespace or name can have up to 128 characters.
- You can specify up to 5 namespaces in a label.
- Don't use the following reserved words in your label specification:
aws
,waf
,managed
,rulegroup
,webacl
,regexpatternset
, oripset
.
For example, myLabelName
or nameSpace1:nameSpace2:myLabelName
.
Rule
, rule_name
- The name of the rule. You can't change the name of a Rule
after you
create it.
$sel:priority:Rule'
, rule_priority
- If you define more than one Rule
in a WebACL
, WAF evaluates each
request against the Rules
in order based on the value of Priority
.
WAF processes rules with lower priority first. The priorities don't
need to be consecutive, but they must all be different.
$sel:statement:Rule'
, rule_statement
- The WAF processing statement for the rule, for example
ByteMatchStatement or SizeConstraintStatement.
$sel:visibilityConfig:Rule'
, rule_visibilityConfig
- Defines and enables Amazon CloudWatch metrics and web request sample
collection.
