Inserts or deletes ByteMatchTuple objects (filters) in a ByteMatchSet.
For each ByteMatchTuple
object, you specify the following values:
waf_update_byte_match_set(ByteMatchSetId, ChangeToken, Updates)
[required] The ByteMatchSetId
of the ByteMatchSet that you want to update.
ByteMatchSetId
is returned by CreateByteMatchSet and by
ListByteMatchSets.
[required] The value returned by the most recent call to GetChangeToken.
[required] An array of ByteMatchSetUpdate
objects that you want to insert into or
delete from a ByteMatchSet. For more information, see the applicable
data types:
ByteMatchSetUpdate: Contains Action
and ByteMatchTuple
ByteMatchTuple: Contains FieldToMatch
, PositionalConstraint
,
TargetString
, and TextTransformation
FieldToMatch: Contains Data
and Type
svc$update_byte_match_set( ByteMatchSetId = "string", ChangeToken = "string", Updates = list( list( Action = "INSERT"|"DELETE", ByteMatchTuple = list( FieldToMatch = list( Type = "URI"|"QUERY_STRING"|"HEADER"|"METHOD"|"BODY"|"SINGLE_QUERY_ARG"|"ALL_QUERY_ARGS", Data = "string" ), TargetString = raw, TextTransformation = "NONE"|"COMPRESS_WHITE_SPACE"|"HTML_ENTITY_DECODE"|"LOWERCASE"|"CMD_LINE"|"URL_DECODE", PositionalConstraint = "EXACTLY"|"STARTS_WITH"|"ENDS_WITH"|"CONTAINS"|"CONTAINS_WORD" ) ) ) )
Whether to insert or delete the object from the array. If you want
to change a ByteMatchSetUpdate
object, you delete the existing
object and add a new one.
The part of a web request that you want AWS WAF to inspect, such as
a query string or the value of the User-Agent
header.
The bytes (typically a string that corresponds with ASCII
characters) that you want AWS WAF to look for. For more information,
including how you specify the values for the AWS WAF API and the AWS
CLI or SDKs, see TargetString
in the ByteMatchTuple data type.
Where to look, such as at the beginning or the end of a query string.
Whether to perform any conversions on the request, such as converting it to lowercase, before inspecting it for the specified string.
For example, you can add a ByteMatchSetUpdate
object that matches web
requests in which User-Agent
headers contain the string BadBot
. You
can then configure AWS WAF to block those requests.
To create and configure a ByteMatchSet
, perform the following steps:
Create a ByteMatchSet.
For more information, see
CreateByteMatchSet.
Use GetChangeToken to get the change token that you provide in the
ChangeToken
parameter of an UpdateByteMatchSet
request.
Submit an UpdateByteMatchSet
request to specify the part of the
request that you want AWS WAF to inspect (for example, the header or
the URI) and the value that you want AWS WAF to watch for.
For more information about how to use the AWS WAF API to allow or block HTTP requests, see the AWS WAF Developer Guide.
