CfnSqlInjectionMatchSet
- class aws_cdk.aws_waf.CfnSqlInjectionMatchSet(scope, id, *, name, sql_injection_match_tuples=None)
Bases:
CfnResource
A CloudFormation
AWS::WAF::SqlInjectionMatchSet
.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 WAF V2 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.
A complex type that contains
SqlInjectionMatchTuple
objects, which specify the parts of web requests that you want AWS WAF to inspect for snippets of malicious SQL code and, if you want AWS WAF to inspect a header, the name of the header. If aSqlInjectionMatchSet
contains more than oneSqlInjectionMatchTuple
object, a request needs to include snippets of SQL code in only one of the specified parts of the request to be considered a match.- CloudformationResource:

# The code below shows an example of how to instantiate this type. # The values are placeholders you should change. import aws_cdk.aws_waf as waf cfn_sql_injection_match_set = waf.CfnSqlInjectionMatchSet(self, "MyCfnSqlInjectionMatchSet", name="name", # the properties below are optional sql_injection_match_tuples=[waf.CfnSqlInjectionMatchSet.SqlInjectionMatchTupleProperty( field_to_match=waf.CfnSqlInjectionMatchSet.FieldToMatchProperty( type="type", # the properties below are optional data="data" ), text_transformation="textTransformation" )] )
Create a new
AWS::WAF::SqlInjectionMatchSet
.- Parameters:
scope (
Construct
) –scope in which this resource is defined.
id (
str
) –scoped id of the resource.
name (
str
) – The name, if any, of theSqlInjectionMatchSet
.sql_injection_match_tuples (
Union
[IResolvable
,Sequence
[Union
[IResolvable
,SqlInjectionMatchTupleProperty
,Dict
[str
,Any

]) – Specifies the parts of web requests that you want to inspect for snippets of malicious SQL code.
Methods
- add_deletion_override(path)
Syntactic sugar for
addOverride(path, undefined)
.- Parameters:
path (
str
) – The path of the value to delete.- Return type:
None
- add_depends_on(target)
Indicates that this resource depends on another resource and cannot be provisioned unless the other resource has been successfully provisioned.
This can be used for resources across stacks (or nested stack) boundaries and the dependency will automatically be transferred to the relevant scope.
- Parameters:
target (
CfnResource
)- Return type:
None
- add_metadata(key, value)
Add a value to the CloudFormation Resource Metadata.
- Parameters:
key (
str
)value (
Any
)
- See:
- Return type:
None
https://docs.aws.amazon.com/AWSCloudFormation/latest/UserGuide/metadata-section-structure.html
Note that this is a different set of metadata from CDK node metadata; this metadata ends up in the stack template under the resource, whereas CDK node metadata ends up in the Cloud Assembly.
- add_override(path, value)
Adds an override to the synthesized CloudFormation resource.
To add a property override, either use
addPropertyOverride
or prefixpath
with “Properties.” (i.e.Properties.TopicName
).If the override is nested, separate each nested level using a dot (.) in the path parameter. If there is an array as part of the nesting, specify the index in the path.
To include a literal
.
in the property name, prefix with a\
. In most programming languages you will need to write this as"\\."
because the\
itself will need to be escaped.For example:
cfn_resource.add_override("Properties.GlobalSecondaryIndexes.0.Projection.NonKeyAttributes", ["myattribute"]) cfn_resource.add_override("Properties.GlobalSecondaryIndexes.1.ProjectionType", "INCLUDE")
would add the overrides Example:
"Properties": { "GlobalSecondaryIndexes": [ { "Projection": { "NonKeyAttributes": [ "myattribute" ] ... } ... }, { "ProjectionType": "INCLUDE" ... }, ] ... }
The
value
argument toaddOverride
will not be processed or translated in any way. Pass raw JSON values in here with the correct capitalization for CloudFormation. If you pass CDK classes or structs, they will be rendered with lowercased key names, and CloudFormation will reject the template.- Parameters:
path (
str
) –The path of the property, you can use dot notation to override values in complex types. Any intermdediate keys will be created as needed.
value (
Any
) –The value. Could be primitive or complex.
- Return type:
None
- add_property_deletion_override(property_path)
Adds an override that deletes the value of a property from the resource definition.
- Parameters:
property_path (
str
) – The path to the property.- Return type:
None
- add_property_override(property_path, value)
Adds an override to a resource property.
Syntactic sugar for
addOverride("Properties.<...>", value)
.- Parameters:
property_path (
str
) – The path of the property.value (
Any
) – The value.
- Return type:
None
- apply_removal_policy(policy=None, *, apply_to_update_replace_policy=None, default=None)
Sets the deletion policy of the resource based on the removal policy specified.
The Removal Policy controls what happens to this resource when it stops being managed by CloudFormation, either because you’ve removed it from the CDK application or because you’ve made a change that requires the resource to be replaced.
The resource can be deleted (
RemovalPolicy.DESTROY
), or left in your AWS account for data recovery and cleanup later (RemovalPolicy.RETAIN
).- Parameters:
policy (
Optional
[RemovalPolicy
])apply_to_update_replace_policy (
Optional
[bool
]) – Apply the same deletion policy to the resource’s “UpdateReplacePolicy”. Default: truedefault (
Optional
[RemovalPolicy
]) – The default policy to apply in case the removal policy is not defined. Default: - Default value is resource specific. To determine the default value for a resoure, please consult that specific resource’s documentation.
- Return type:
None
- get_att(attribute_name)
Returns a token for an runtime attribute of this resource.
Ideally, use generated attribute accessors (e.g.
resource.arn
), but this can be used for future compatibility in case there is no generated attribute.- Parameters:
attribute_name (
str
) – The name of the attribute.- Return type:
- get_metadata(key)
Retrieve a value value from the CloudFormation Resource Metadata.
- Parameters:
key (
str
)- See:
- Return type:
Any
https://docs.aws.amazon.com/AWSCloudFormation/latest/UserGuide/metadata-section-structure.html
Note that this is a different set of metadata from CDK node metadata; this metadata ends up in the stack template under the resource, whereas CDK node metadata ends up in the Cloud Assembly.
- inspect(inspector)
Examines the CloudFormation resource and discloses attributes.
- Parameters:
inspector (
TreeInspector
) –tree inspector to collect and process attributes.
- Return type:
None
- override_logical_id(new_logical_id)
Overrides the auto-generated logical ID with a specific ID.
- Parameters:
new_logical_id (
str
) – The new logical ID to use for this stack element.- Return type:
None
- to_string()
Returns a string representation of this construct.
- Return type:
str
- Returns:
a string representation of this resource
Attributes
- CFN_RESOURCE_TYPE_NAME = 'AWS::WAF::SqlInjectionMatchSet'
- cfn_options
Options for this resource, such as condition, update policy etc.
- cfn_resource_type
AWS resource type.
- creation_stack
return:
the stack trace of the point where this Resource was created from, sourced from the +metadata+ entry typed +aws:cdk:logicalId+, and with the bottom-most node +internal+ entries filtered.
- logical_id
The logical ID for this CloudFormation stack element.
The logical ID of the element is calculated from the path of the resource node in the construct tree.
To override this value, use
overrideLogicalId(newLogicalId)
.- Returns:
the logical ID as a stringified token. This value will only get resolved during synthesis.
- name
The name, if any, of the
SqlInjectionMatchSet
.
- node
The construct tree node associated with this construct.
- ref
Return a string that will be resolved to a CloudFormation
{ Ref }
for this element.If, by any chance, the intrinsic reference of a resource is not a string, you could coerce it to an IResolvable through
Lazy.any({ produce: resource.ref })
.
- sql_injection_match_tuples
Specifies the parts of web requests that you want to inspect for snippets of malicious SQL code.
- stack
The stack in which this element is defined.
CfnElements must be defined within a stack scope (directly or indirectly).
Static Methods
- classmethod is_cfn_element(x)
Returns
true
if a construct is a stack element (i.e. part of the synthesized cloudformation template).Uses duck-typing instead of
instanceof
to allow stack elements from different versions of this library to be included in the same stack.- Parameters:
x (
Any
)- Return type:
bool
- Returns:
The construct as a stack element or undefined if it is not a stack element.
- classmethod is_cfn_resource(construct)
Check whether the given construct is a CfnResource.
- Parameters:
construct (
IConstruct
)- Return type:
bool
- classmethod is_construct(x)
Return whether the given object is a Construct.
- Parameters:
x (
Any
)- Return type:
bool
FieldToMatchProperty
- class CfnSqlInjectionMatchSet.FieldToMatchProperty(*, type, data=None)
Bases:
object
The part of a web request that you want to inspect, such as a specified header or a query string.
- Parameters:
type (
str
) – The part of the web request that you want AWS WAF to search for a specified string. Parts of a request that you can search include the following: -HEADER
: A specified request header, for example, the value of theUser-Agent
orReferer
header. If you chooseHEADER
for the type, specify the name of the header inData
. -METHOD
: The HTTP method, which indicated the type of operation that the request is asking the origin to perform. Amazon CloudFront supports the following methods:DELETE
,GET
,HEAD
,OPTIONS
,PATCH
,POST
, andPUT
. -QUERY_STRING
: A query string, which is the part of a URL that appears after a?
character, if any. -URI
: The part of a web request that identifies a resource, for example,/images/daily-ad.jpg
. -BODY
: The part of a request that contains any additional data that you want to send to your web server as the HTTP request body, such as data from a form. The request body immediately follows the request headers. Note that only the first8192
bytes of the request body are forwarded to AWS WAF for inspection. To allow or block requests based on the length of the body, you can create a size constraint set. -SINGLE_QUERY_ARG
: The parameter in the query string that you will inspect, such as UserName or SalesRegion . The maximum length forSINGLE_QUERY_ARG
is 30 characters. -ALL_QUERY_ARGS
: Similar toSINGLE_QUERY_ARG
, but rather than inspecting a single parameter, AWS WAF will inspect all parameters within the query for the value or regex pattern that you specify inTargetString
.data (
Optional
[str
]) – When the value ofType
isHEADER
, enter the name of the header that you want AWS WAF to search, for example,User-Agent
orReferer
. The name of the header is not case sensitive. When the value ofType
isSINGLE_QUERY_ARG
, enter the name of the parameter that you want AWS WAF to search, for example,UserName
orSalesRegion
. The parameter name is not case sensitive. If the value ofType
is any other value, omitData
.

Bases:
object
This is AWS WAF Classic documentation.
For more information, see AWS WAF Classic in the developer guide. .. epigraph:
*For the latest version of AWS WAF* , use the AWS WAF V2 API and see the `AWS WAF Developer Guide <https://docs.aws.amazon.com/waf/latest/developerguide/waf-chapter.html>`_ . With the latest version, AWS WAF has a single set of endpoints for regional and global use.
Specifies the part of a web request that you want AWS WAF to inspect for snippets of malicious SQL code and, if you want AWS WAF to inspect a header, the name of the header.
Attributes
- field_to_match
The part of a web request that you want to inspect, such as a specified header or a query string.
- text_transformation
Text transformations eliminate some of the unusual formatting that attackers use in web requests in an effort to bypass AWS WAF .
If you specify a transformation, AWS WAF performs the transformation on
FieldToMatch
before inspecting it for a match.You can only specify a single type of TextTransformation.
CMD_LINE
When you’re concerned that attackers are injecting an operating system command line command and using unusual formatting to disguise some or all of the command, use this option to perform the following transformations:
Delete the following characters: “ ‘ ^
Delete spaces before the following characters: / (
Replace the following characters with a space: , ;
Replace multiple spaces with one space
Convert uppercase letters (A-Z) to lowercase (a-z)
COMPRESS_WHITE_SPACE
Use this option to replace the following characters with a space character (decimal 32):
f, formfeed, decimal 12
t, tab, decimal 9
n, newline, decimal 10
r, carriage return, decimal 13
v, vertical tab, decimal 11
non-breaking space, decimal 160
COMPRESS_WHITE_SPACE
also replaces multiple spaces with one space.HTML_ENTITY_DECODE
Use this option to replace HTML-encoded characters with unencoded characters.
HTML_ENTITY_DECODE
performs the following operations:Replaces
(ampersand)quot;
with"
Replaces
(ampersand)nbsp;
with a non-breaking space, decimal 160Replaces
(ampersand)lt;
with a “less than” symbolReplaces
(ampersand)gt;
with>
Replaces characters that are represented in hexadecimal format,
(ampersand)#xhhhh;
, with the corresponding charactersReplaces characters that are represented in decimal format,
(ampersand)#nnnn;
, with the corresponding characters
LOWERCASE
Use this option to convert uppercase letters (A-Z) to lowercase (a-z).
URL_DECODE
Use this option to decode a URL-encoded value.
NONE
Specify
NONE
if you don’t want to perform any text transformations.
