- Rapid Deployment Policy (RDP)The Rapid Deployment Policy (RDP) policy template is recommended for beginners. It provides essential security with a low false-positive rate. This policy is transparent. It does not block or learn new entities, but only reports violations and learning suggestions to turn off signatures and features that create false-positives.
- FundamentalThe Fundamental policy template is recommended for intermediate users. It provides better security; actively blocks violations and automatically learns from false positives. It might require more time to operate and tune.
- ComprehensiveThe Comprehensive policy template is recommended for expert users. It provides maximum security with all violations, features, and learning is turned on. It requires more time to operate and tune.
- Passive Deployment Policy (PDP)The Passive Deployment Policy (PDP) policy template is similar to Comprehensive template but is meant to be used with a SPAN port, passively alerting for violations and turning off any feature that modifies the response.
- Vulnerability Assessment BaselineThe Vulnerability Assessment Baseline policy template is meant to be used with the results of a vulnerability assessment tool scan, and it turns off all unrelated security features.
- API SecurityThe API Security policy template is similar to RDP template but includes changes to benefit API Security, such as JSON, XML, and OpenAPI validations.
- Application-Ready and Deprecated TemplatesThe Application-Ready and Deprecated policy templates are meant to be used with specific applications and contain only the relevant signatures and features.

Declarative policy supported violations
Modified ASM cookie
The system checks that the request contains an ASM cookie that has not been modified or tampered with. Blocks modified requests.
Attack signature detected
The system examines the HTTP message for known attacks by matching it against known attack patterns.
Determined per signature set.
IP is blacklisted
The violation is issued when a request comes from an IP address that falls in the range of an IP address exception marked for “always blocking”, that is, the black list of IPs.
Would trigger Violation Rating of 5.
The system checks that the timestamp in the HTTP cookie is not old. An old timestamp indicates that a client session has expired. Blocks expired requests. The timestamp is extracted and validated against the current time. If the timestamp is expired and it is not an entry point, the system issues the Expired Timestamp violation.
Illegal cookie length
The system checks that the request does not include a cookie header that exceeds the acceptable length specified in the security policy.
Determined by policy setting which is disabled in default template.
Cookie not RFC-compliant
This violation occurs when HTTP cookies contain at least one of the following components:
Modified domain cookie(s)
The system checks that the web application cookies within the request have not been tampered, and the system checks that the request includes a web application cookie defined in the security policy.
Determined by cookie type: applied to “enforced” cookies.
Data Guard: Information leakage detected
The system examines responses and searches for sensitive information.
Controlled by the DG enable flag which is disabled in default template.
Failed to convert character
The system detects that one of the characters does not comply with the configured language encoding of the web application’s security policy.
Evasion technique detected
This category contains a list of evasion techniques that attackers use to bypass detection.
Illegal file type
The system checks that the requested file type is configured as a valid file type, or not configured as an invalid file type, within the security policy.
Only for disallowed file types.
Illegal header length
The system checks that the request includes a total HTTP header length that does not exceed the length specified in the security policy.
The actual size in default policy is 4 KB
Illegal meta character in header
The system checks that the values of all headers within the request only contain meta characters defined as allowed in the security policy.
HTTP protocol compliance failed
This category contains a list of validation checks that the system performs on HTTP requests to ensure that the requests are formatted properly.
Illegal HTTP response status
The server response contains an HTTP status code that is not defined as valid in the security policy.
JSON data does not comply with format settings
The system checks that the request contains JSON content and complies with the various request limits within the defense configuration in the security policy’s JSON profile. Enforces valid JSON requests and protects the server from JSON parser attacks. This violation is generated when a problem is detected in a JSON request, generally checking the message according to boundaries such as the message’s size and meta characters in parameter value.
Controlled from the default JSON profile.
Malformed JSON data
The system checks that the request contains JSON content that is well-formed. Enforces parsable JSON requests.
The system checks that the request references an HTTP request method that is found in the security policy. Enforces desired HTTP methods; GET and POST are always allowed.
These HTTP methods are supported:
Illegal POST data length
The system checks that the request contains POST data whose length does not exceed the acceptable length specified in the security policy.
In * file type entity. This check is disabled by default.
Illegal query string length
The system checks that the request contains a query string whose length does not exceed the acceptable length specified in the security policy.
In * file type entity. Actual size is 2 KB.
Illegal request length
The system checks that the request length does not exceed the acceptable length specified in the security policy per the requested file type.
In * file type entity. This check is disabled by default.
Request length exceeds defined buffer size
The system checks that the request length is not larger than the maximum memory buffer size of the ASM. Note that this is a BIG-IP unit parameter that protects the ASM from consuming too much memory across all security policies which are active on the device.
Default is 10MB
Illegal URL length
The system checks that the request is for a URL whose length does not exceed the acceptable length specified in the security policy.
In * file type entity. Actual size is 2 KB.
Illegal meta character in URL
The system checks that the incoming request includes a URL that contains only meta characters defined as allowed in the security policy. Enforces a desired set of acceptable characters.
XML data does not comply with format settings
The system checks that the request contains XML data that complies with the various document limits within the defense configuration in the security policy’s XML profile. Enforces proper XML requests and the data failed format/defense settings such as the maximum document length. This violation is generated when a problem in an XML document is detected (for example, an XML bomb), generally checking the message according to boundaries such as the message’s size, maximum depth, and maximum number of children.
Controlled by the default XML profile
Malformed XML data
The system checks that the request contains XML data that is well-formed, according to W3C standards. Enforces proper XML requests.
Request is likely a threat
The combination of violations in this request determined that the request is likely to be a threat.
For VR = 4 or 5
Request needs further examination
The combination of violations could not determine whether the request is a threat or violations are false positives thus requiring more examination.
For VR = 3
Null in multi-part parameter value
The system checks that the multi-part request has a parameter value that does not contain the NULL character (0x00). If a multipart parameter with binary content type contains NULL in its value, the enforcer issues this violation. The exceptions to this are:
Illegal meta character in parameter name
The system checks that all parameter names within the incoming request only contain meta characters defined as allowed in the security policy.
Illegal meta character in value
The system checks that all parameter values, XML element/attribute values, or JSON values within the request only contain meta characters defined as allowed in the security policy. Enforces proper input values.
Declarative policy HTTP sub-violations
Unparsable request content
This violation is triggered when the system’s parser cannot parse the message.
Several Content-Length headers
More than one content-length header is a non RFC violation. Indicates an HTTP response splitting attack.
POST request with Content-Length: 0
Null in request
The system issues a violation for requests with a NULL character anywhere in the request (except for a NULL in the binary part of a multipart request).
Null in body
No Host header in HTTP/1.1 request
Examines requests using HTTP/1.1 to see whether they contain a “Host” header.
Multiple host headers
Examines requests to ensure that they contain only a single “Host” header.
Host header contains IP address
The system verifies that the request’s host header value is not an IP address to prevent non-standard requests.
High ASCII characters in headers
Checks for high ASCII characters in headers (greater than 127).
Header name with no header value
The system checks for a header name without a header value.
CRLF characters before request start
Examines whether there is a CRLF character before the request method. If there is, the system issues a violation.
Content length should be a positive number
The Content-Length header value should be greater than zero; only a numeric positive number value is accepted.
Chunked request with Content-Length header
The system checks for a Content-Length header within chunked requests.
Check maximum number of parameters
The system compares the number of parameters in the request to the maximum configured number of parameters.
Check maximum number of headers
The system compares the request headers to the maximal configured number of headers.
Body in GET or HEAD requests
Examines GET and HEAD requests which have a body.
Bad multipart/form-data request parsing
When the content type of a request header contains the substring “Multipart/form-data”, the system checks whether each multipart request chunk contains the strings “Content-Disposition” and “Name”. If they do not, the system issues a violation.
Bad multipart parameters parsing
The system checks the following:
If one of these is false, the system issues a violation.
Bad HTTP version
Enforces legal HTTP version number (only 0.9 or higher allowed).
Bad host header value
Declarative policy evasion sub-violations
Performs Microsoft %u unicode decoding (%UXXXX where X is a hexadecimal digit). For example, the system turns a%u002fb to a/b. The system performs this action on URI and parameter input to evaluate if the request contains an attack.
The system detects the following characters in the URI: 9 (0x09), 11 (0x0B), 12 (0x0C), and 13 (0x0D).
The system detects illegal HEX encoding. Reports unescaping errors (such as %RR).
Bare byte decoding
The system detects higher ASCII bytes (greater than 127).
Normalizes backslashes () to slashes (/) for further processing.
IIS Unicode codepoints
Handles the mapping of IIS specific non-ASCII codepoints. Indicates that, when a character is greater than ‘0x00FF’, the system decodes %u according to an ANSI Latin 1 (Windows 1252) code page mapping. For example, the system turns a%u2044b to a/b. The system performs this action on URI and parameter input.
The system decodes URI and parameter values multiple times according to the number specified before the request is considered an evasion.
