For this example, the rate limit is 1,000. Requests that meet both of the conditions in the statements are counted. If the count exceeds 1,000 requests per five minutes, the rule action triggers. Requests that do not meet both conditions are not counted towards the rate limit and are not affected by this rule.</p> <p>You cannot nest a <code>RateBasedStatement</code> inside another statement, for example inside a <code>NotStatement</code> or <code>OrStatement</code>.

These are helpful in reducing effectiveness of attackers who inject an operating system command-line command and use unusual formatting to disguise some or all of the command. </p> <ul> <li> <p>Delete the following characters: <code>\\ \" ' ^</code> </p> </li> <li> <p>Delete spaces before the following characters: <code>/ (</code> </p> </li> <li> <p>Replace the following characters with a space: <code>, ;</code> </p> </li> <li> <p>Replace multiple spaces with one space</p> </li> <li> <p>Convert uppercase letters (A-Z) to lowercase (a-z)</p> </li> </ul> <p> <b>COMPRESS_WHITE_SPACE</b> - Replace these characters with a space character (decimal 32): </p> <ul> <li> <p> <code>\\f</code>, formfeed, decimal 12</p> </li> <li> <p> <code>\\t</code>, tab, decimal 9</p> </li> <li> <p> <code>\\n</code>, newline, decimal 10</p> </li> <li> <p> <code>\\r</code>, carriage return, decimal 13</p> </li> <li> <p> <code>\\v</code>, vertical tab, decimal 11</p> </li> <li> <p>Non-breaking space, decimal 160</p> </li> </ul> <p> <code>COMPRESS_WHITE_SPACE</code> also replaces multiple spaces with one space.</p> <p> <b>CSS_DECODE</b> - Decode characters that were encoded using CSS 2.x escape rules <code>syndata.html#characters</code>. This function uses up to two bytes in the decoding process, so it can help to uncover ASCII characters that were encoded using CSS encoding that wouldn’t typically be encoded. It's also useful in countering evasion, which is a combination of a backslash and non-hexadecimal characters. For example, <code>ja\\vascript</code> for javascript. </p> <p> <b>ESCAPE_SEQ_DECODE</b> - Decode the following ANSI C escape sequences: <code>\\a</code>, <code>\\b</code>, <code>\\f</code>, <code>\\n</code>, <code>\\r</code>, <code>\\t</code>, <code>\\v</code>, <code>\\\\</code>, <code>\\?</code>, <code>\\'</code>, <code>\\\"</code>, <code>\\xHH</code> (hexadecimal), <code>\\0OOO</code> (octal). Encodings that aren't valid remain in the output. </p> <p> <b>HEX_DECODE</b> - Decode a string of hexadecimal characters into a binary.</p> <p> <b>HTML_ENTITY_DECODE</b> - Replace HTML-encoded characters with unencoded characters. <code>HTML_ENTITY_DECODE</code> performs these operations: </p> <ul> <li> <p>Replaces <code>(ampersand)quot;</code> with <code>\"</code> </p> </li> <li> <p>Replaces <code>(ampersand)nbsp;</code> with a non-breaking space, decimal 160</p> </li> <li> <p>Replaces <code>(ampersand)lt;</code> with a \"less than\" symbol</p> </li> <li> <p>Replaces <code>(ampersand)gt;</code> with <code>&gt;</code> </p> </li> <li> <p>Replaces characters that are represented in hexadecimal format, <code>(ampersand)#xhhhh;</code>, with the corresponding characters</p> </li> <li> <p>Replaces characters that are represented in decimal format, <code>(ampersand)#nnnn;</code>, with the corresponding characters</p> </li> </ul> <p> <b>JS_DECODE</b> - Decode JavaScript escape sequences. If a <code>\\</code> <code>u</code> <code>HHHH</code> code is in the full-width ASCII code range of <code>FF01-FF5E</code>, then the higher byte is used to detect and adjust the lower byte. If not, only the lower byte is used and the higher byte is zeroed, causing a possible loss of information. </p> <p> <b>LOWERCASE</b> - Convert uppercase letters (A-Z) to lowercase (a-z). </p> <p> <b>MD5</b> - Calculate an MD5 hash from the data in the input. The computed hash is in a raw binary form. </p> <p> <b>NONE</b> - Specify <code>NONE</code> if you don't want any text transformations. </p> <p> <b>NORMALIZE_PATH</b> - Remove multiple slashes, directory self-references, and directory back-references that are not at the beginning of the input from an input string. </p> <p> <b>NORMALIZE_PATH_WIN</b> - This is the same as <code>NORMALIZE_PATH</code>, but first converts backslash characters to forward slashes. </p> <p> <b>REMOVE_NULLS</b> - Remove all <code>NULL</code> bytes from the input. </p> <p> <b>REPLACE_COMMENTS</b> - Replace each occurrence of a C-style comment (<code>/* ... */</code>) with a single space. Multiple consecutive occurrences are not compressed. Unterminated comments are also replaced with a space (ASCII 0x20). However, a standalone termination of a comment (<code>*/</code>) is not acted upon. </p> <p> <b>REPLACE_NULLS</b> - Replace NULL bytes in the input with space characters (ASCII <code>0x20</code>). </p> <p> <b>SQL_HEX_DECODE</b> - Decode SQL hex data. Example (<code>0x414243</code>) will be decoded to (<code>ABC</code>).</p> <p> <b>URL_DECODE</b> - Decode a URL-encoded value. </p> <p> <b>URL_DECODE_UNI</b> - Like <code>URL_DECODE</code>, but with support for Microsoft-specific <code>%u</code> encoding. If the code is in the full-width ASCII code range of <code>FF01-FF5E</code>, the higher byte is used to detect and adjust the lower byte. Otherwise, only the lower byte is used and the higher byte is zeroed. </p> <p> <b>UTF8_TO_UNICODE</b> - Convert all UTF-8 character sequences to Unicode. This helps input normalization, and minimizing false-positives and false-negatives for non-English languages.</p>"

  "documentation":"<fullname>WAF</fullname> <note> <p>This is the latest version of the <b>WAF</b> 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.</p> <p>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. </p> <p>For information, including how to migrate your WAF resources to this version, see the <a href=\"https://docs.aws.amazon.com/waf/latest/developerguide/waf-chapter.html\">WAF Developer Guide</a>. </p> </note> <p>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.</p> <p>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 <a href=\"https://docs.aws.amazon.com/waf/latest/developerguide/what-is-aws-waf.html\">WAF Developer Guide</a>.</p> <p>You can make calls using the endpoints listed in <a href=\"https://docs.aws.amazon.com/general/latest/gr/waf.html\">WAF endpoints and quotas</a>. </p> <ul> <li> <p>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. </p> </li> <li> <p>For Amazon CloudFront applications, you must use the API endpoint listed for US East (N. Virginia): us-east-1.</p> </li> </ul> <p>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 <a href=\"http://aws.amazon.com/tools/#SDKs\">Amazon Web Services SDKs</a>.</p> <p>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:</p> <ul> <li> <p>You use one API for both global and regional applications. Where you need to distinguish the scope, you specify a <code>Scope</code> parameter and set it to <code>CLOUDFRONT</code> or <code>REGIONAL</code>. </p> </li> <li> <p>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.</p> </li> <li> <p>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.</p> </li> </ul>"
