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.

The action that WAF should take on a web request when it matches the rule statement.

evaluations. -

Instance Attribute Details
#action ⇒ Types::RuleAction
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.

#captcha_config ⇒ Types::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.

#name ⇒ String
The name of the rule. You can't change the name of a Rule
after
you create it.

#override_action ⇒ Types::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
.

#priority ⇒ Integer
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.

#rule_labels ⇒ Array<Types::Label>
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
.
