AWS.WAFV2 (aws-elixir v0.8.0) View Source

WAF

This is the latest version of the WAF API, released in November, 2019.

The names of the entities that you use to access this API, like endpoints and namespaces, all have the versioning information added, like "V2" or "v2", to distinguish from the prior version. We recommend migrating your resources to this version, because it has a number of significant improvements.

If you used WAF prior to this release, you can't use this WAFV2 API to access any WAF resources that you created before. You can access your old rules, web ACLs, and other WAF resources only through the WAF Classic APIs. The WAF Classic APIs have retained the prior names, endpoints, and namespaces.

For information, including how to migrate your WAF resources to this version, see the WAF Developer Guide.

WAF is a web application firewall that lets you monitor the HTTP and HTTPS requests that are forwarded to Amazon CloudFront, an Amazon API Gateway REST API, an Application Load Balancer, or an AppSync GraphQL API. WAF also lets you control access to your content. Based on conditions that you specify, such as the IP addresses that requests originate from or the values of query strings, the Amazon API Gateway REST API, CloudFront distribution, the Application Load Balancer, or the AppSync GraphQL API responds to requests either with the requested content or with an HTTP 403 status code (Forbidden). You also can configure CloudFront to return a custom error page when a request is blocked.

This API guide is for developers who need detailed information about WAF API actions, data types, and errors. For detailed information about WAF features and an overview of how to use WAF, see the WAF Developer Guide.

You can make calls using the endpoints listed in Amazon Web Services Service Endpoints for WAF.

  • For regional applications, you can use any of the endpoints in the list. A regional application can be an Application Load Balancer (ALB), an Amazon API Gateway REST API, or an AppSync GraphQL API.

  • For Amazon CloudFront applications, you must use the API endpoint listed for US East (N. Virginia): us-east-1.

Alternatively, you can use one of the Amazon Web Services SDKs to access an API that's tailored to the programming language or platform that you're using. For more information, see Amazon Web Services SDKs.

We currently provide two versions of the WAF API: this API and the prior versions, the classic WAF APIs. This new API provides the same functionality as the older versions, with the following major improvements:

  • You use one API for both global and regional applications. Where you need to distinguish the scope, you specify a Scope parameter and set it to CLOUDFRONT or REGIONAL.

  • You can define a web ACL or rule group with a single call, and update it with a single call. You define all rule specifications in JSON format, and pass them to your rule group or web ACL calls.

  • The limits WAF places on the use of rules more closely reflects the cost of running each type of rule. Rule groups include capacity settings, so you know the maximum cost of a rule group when you use it.

associate_web_acl(client, input, options \\ [])

View Source

Associates a web ACL with a regional application resource, to protect the resource.

A regional application can be an Application Load Balancer (ALB), an Amazon API Gateway REST API, or an AppSync GraphQL API.

For Amazon CloudFront, don't use this call. Instead, use your CloudFront distribution configuration. To associate a web ACL, in the CloudFront call UpdateDistribution, set the web ACL ID to the Amazon Resource Name (ARN) of the web ACL. For information, see UpdateDistribution.

Link to this function

check_capacity(client, input, options \\ [])

View Source

Returns the web ACL capacity unit (WCU) requirements for a specified scope and set of rules.

You can use this to check the capacity requirements for the rules you want to use in a RuleGroup or WebACL.

WAF uses WCUs to calculate and control the operating resources that are used to run your rules, rule groups, and web ACLs. WAF calculates capacity differently for each rule type, to reflect the relative cost of each rule. Simple rules that cost little to run use fewer WCUs than more complex rules that use more processing power. Rule group capacity is fixed at creation, which helps users plan their web ACL WCU usage when they use a rule group. The WCU limit for web ACLs is 1,500.

Link to this function

create_ip_set(client, input, options \\ [])

View Source

Creates an IPSet, which you use to identify web requests that originate from specific IP addresses or ranges of IP addresses.

For example, if you're receiving a lot of requests from a ranges of IP addresses, you can configure WAF to block them using an IPSet that lists those IP addresses.

Link to this function

create_regex_pattern_set(client, input, options \\ [])

View Source

Link to this function

create_rule_group(client, input, options \\ [])

View Source

Creates a RuleGroup per the specifications provided.

A rule group defines a collection of rules to inspect and control web requests that you can use in a WebACL. When you create a rule group, you define an immutable capacity limit. If you update a rule group, you must stay within the capacity. This allows others to reuse the rule group with confidence in its capacity requirements.

Link to this function

create_web_acl(client, input, options \\ [])

View Source

Creates a WebACL per the specifications provided.

A web ACL defines a collection of rules to use to inspect and control web requests. Each rule has an action defined (allow, block, or count) for requests that match the statement of the rule. In the web ACL, you assign a default action to take (allow, block) for any request that does not match any of the rules. The rules in a web ACL can be a combination of the types Rule, RuleGroup, and managed rule group. You can associate a web ACL with one or more Amazon Web Services resources to protect. The resources can be an Amazon CloudFront distribution, an Amazon API Gateway REST API, an Application Load Balancer, or an AppSync GraphQL API.

You can specify a sample size of up to 500 requests, and you can specify any time range in the previous three hours.

GetSampledRequests returns a time range, which is usually the time range that you specified. However, if your resource (such as a CloudFront distribution) received 5,000 requests before the specified time range elapsed, GetSampledRequests returns an updated time range. This new time range indicates the actual period during which WAF selected the requests in the sample.

put_logging_configuration(client, input, options \\ [])

View Source

Enables the specified LoggingConfiguration, to start logging from a web ACL, according to the configuration provided.

You can access information about all traffic that WAF inspects using the following steps:

  1. Create an Amazon Kinesis Data Firehose.

Create the data firehose with a PUT source and in the Region that you are operating. If you are capturing logs for Amazon CloudFront, always create the firehose in US East (N. Virginia).

Give the data firehose a name that starts with the prefix aws-waf-logs-. For example, aws-waf-logs-us-east-2-analytics.

Do not create the data firehose using a Kinesis stream as your source.

  1. Associate that firehose to your web ACL using a PutLoggingConfiguration request.

When you successfully enable logging using a PutLoggingConfiguration request, WAF will create a service linked role with the necessary permissions to write logs to the Amazon Kinesis Data Firehose. For more information, see Logging Web ACL Traffic Information in the WAF Developer Guide.

This operation completely replaces the mutable specifications that you already have for the logging configuration with the ones that you provide to this call. To modify the logging configuration, retrieve it by calling GetLoggingConfiguration, update the settings as needed, and then provide the complete logging configuration specification to this call.
