update-rule¶

Description¶

Note

This is AWS WAF Classic documentation. For more information, see AWS WAF Classic in the developer guide.

For the latest version of AWS WAF , use the AWS WAFV2 API and see the AWS WAF Developer Guide . With the latest version, AWS WAF has a single set of endpoints for regional and global use.

Inserts or deletes Predicate objects in a Rule . Each Predicate object identifies a predicate, such as a ByteMatchSet or an IPSet , that specifies the web requests that you want to allow, block, or count. If you add more than one predicate to a Rule , a request must match all of the specifications to be allowed, blocked, or counted. For example, suppose that you add the following to a Rule :

A ByteMatchSet that matches the value BadBot in the User-Agent header
An IPSet that matches the IP address 192.0.2.44

You then add the Rule to a WebACL and specify that you want to block requests that satisfy the Rule . For a request to be blocked, the User-Agent header in the request must contain the value BadBot and the request must originate from the IP address 192.0.2.44.

To create and configure a Rule , perform the following steps:

Create and update the predicates that you want to include in the Rule .
Create the Rule . See CreateRule .
Use GetChangeToken to get the change token that you provide in the ChangeToken parameter of an UpdateRule request.
Submit an UpdateRule request to add predicates to the Rule .
Create and update a WebACL that contains the Rule . See CreateWebACL .

If you want to replace one ByteMatchSet or IPSet with another, you delete the existing one and add the new one.

For more information about how to use the AWS WAF API to allow or block HTTP requests, see the AWS WAF Developer Guide .

Synopsis¶

  update-rule
--rule-id <value>
--change-token <value>
--updates <value>
[--cli-input-json | --cli-input-yaml]
[--generate-cli-skeleton <value>]
[--cli-auto-prompt <value>]

Options¶

--rule-id (string)

The RuleId of the Rule that you want to update. RuleId is returned by CreateRule and by ListRules .

--change-token (string)

The value returned by the most recent call to GetChangeToken .

--updates (list)

An array of RuleUpdate objects that you want to insert into or delete from a Rule . For more information, see the applicable data types:

RuleUpdate : Contains Action and Predicate

Predicate : Contains DataId , Negated , and Type

FieldToMatch : Contains Data and Type

(structure)

Note

This is AWS WAF Classic documentation. For more information, see AWS WAF Classic in the developer guide.

For the latest version of AWS WAF , use the AWS WAFV2 API and see the AWS WAF Developer Guide . With the latest version, AWS WAF has a single set of endpoints for regional and global use.

Specifies a Predicate (such as an IPSet ) and indicates whether you want to add it to a Rule or delete it from a Rule .

Action -> (string)

Specify INSERT to add a Predicate to a Rule . Use DELETE to remove a Predicate from a Rule .

Predicate -> (structure)

The ID of the Predicate (such as an IPSet ) that you want to add to a Rule .

Negated -> (boolean)

Set Negated to False if you want AWS WAF to allow, block, or count requests based on the settings in the specified ByteMatchSet , IPSet , SqlInjectionMatchSet , XssMatchSet , RegexMatchSet , GeoMatchSet , or SizeConstraintSet . For example, if an IPSet includes the IP address 192.0.2.44 , AWS WAF will allow or block requests based on that IP address.

Set Negated to True if you want AWS WAF to allow or block a request based on the negation of the settings in the ByteMatchSet , IPSet , SqlInjectionMatchSet , XssMatchSet , RegexMatchSet , GeoMatchSet , or SizeConstraintSet . For example, if an IPSet includes the IP address 192.0.2.44 , AWS WAF will allow, block, or count requests based on all IP addresses except 192.0.2.44 .

Type -> (string)

The type of predicate in a Rule , such as ByteMatch or IPSet .

DataId -> (string)

A unique identifier for a predicate in a Rule , such as ByteMatchSetId or IPSetId . The ID is returned by the corresponding Create or List command.

Shorthand Syntax:

Action=string,Predicate={Negated=boolean,Type=string,DataId=string} ...

JSON Syntax:

[
  {
    "Action": "INSERT"|"DELETE",
    "Predicate": {
      "Negated": true|false,
      "Type": "IPMatch"|"ByteMatch"|"SqlInjectionMatch"|"GeoMatch"|"SizeConstraint"|"XssMatch"|"RegexMatch",
      "DataId": "string"
    }
  }
  ...
]

--cli-input-json | --cli-input-yaml (string) Reads arguments from the JSON string provided. The JSON string follows the format provided by --generate-cli-skeleton. If other arguments are provided on the command line, those values will override the JSON-provided values. It is not possible to pass arbitrary binary values using a JSON-provided value as the string will be taken literally. This may not be specified along with --cli-input-yaml.

--generate-cli-skeleton (string) Prints a JSON skeleton to standard output without sending an API request. If provided with no value or the value input, prints a sample input JSON that can be used as an argument for --cli-input-json. Similarly, if provided yaml-input it will print a sample input YAML that can be used with --cli-input-yaml. If provided with the value output, it validates the command inputs and returns a sample output JSON for that command.

--cli-auto-prompt (boolean) Automatically prompt for CLI input parameters.

See ‘aws help’ for descriptions of global parameters.

Examples¶

To update a rule

The following update-rule command deletes a Predicate object in a rule:

aws waf update-rule --rule-id a123fae4-b567-8e90-1234-5ab67ac8ca90 --change-token 12cs345-67cd-890b-1cd2-c3a4567d89f1 --updates Action="DELETE",Predicate={Negated=false,Type="ByteMatch",DataId="MyByteMatchSetID"}

For more information, see Working with Rules in the AWS WAF developer guide.

Output¶

ChangeToken -> (string)

The ChangeToken that you used to submit the UpdateRule request. You can also use this value to query the status of the request. For more information, see GetChangeTokenStatus .
