update-rule

Description

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 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 create-rule .
  • Use get-change-token to get the change token that you provide in the change-token parameter of an update-rule request.
  • Submit an update-rule request to add predicates to the Rule .
  • Create and update a WebACL that contains the Rule . See create-web-acl .

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 .

Options

--rule-id (string)

The RuleId of the Rule that you want to update. RuleId is returned by create-rule and by list-rules .

--change-token (string)

The value returned by the most recent call to get-change-token .

--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

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 (string) Performs service operation based on the JSON string provided. The JSON string follows the format provided by --generate-cli-skeleton. If other arguments are provided on the command line, the CLI values will override the JSON-provided values.

--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. If provided with the value output, it validates the command inputs and returns a sample output JSON for that command.

Output

ChangeToken -> (string)

The change-token that you used to submit the update-rule request. You can also use this value to query the status of the request. For more information, see get-change-token-status .
