Class JA3Fingerprint

java.lang.Object

software.amazon.awssdk.services.wafv2.model.JA3Fingerprint

All Implemented Interfaces:

Serializable, SdkPojo, ToCopyableBuilder<JA3Fingerprint.Builder,JA3Fingerprint>

@Generated("software.amazon.awssdk:codegen")
public final class JA3Fingerprint
extends Object
implements SdkPojo, Serializable, ToCopyableBuilder<JA3Fingerprint.Builder,JA3Fingerprint>

Match against the request's JA3 fingerprint. The JA3 fingerprint is a 32-character hash derived from the TLS Client Hello of an incoming request. This fingerprint serves as a unique identifier for the client's TLS configuration. WAF calculates and logs this fingerprint for each request that has enough TLS Client Hello information for the calculation. Almost all web requests include this information.

You can use this choice only with a string match ByteMatchStatement with the PositionalConstraint set to EXACTLY.

You can obtain the JA3 fingerprint for client requests from the web ACL logs. If WAF is able to calculate the fingerprint, it includes it in the logs. For information about the logging fields, see Log fields in the WAF Developer Guide.

Provide the JA3 fingerprint string from the logs in your string match statement specification, to match with any future requests that have the same TLS configuration.

Method Detail

fallbackBehavior

public final FallbackBehavior fallbackBehavior()

The match status to assign to the web request if the request doesn't have a JA3 fingerprint.

You can specify the following fallback behaviors:

• MATCH - Treat the web request as matching the rule statement. WAF applies the rule action to the request.

• NO_MATCH - Treat the web request as not matching the rule statement.

If the service returns an enum value that is not available in the current SDK version, fallbackBehavior will return FallbackBehavior.UNKNOWN_TO_SDK_VERSION. The raw value returned by the service is available from fallbackBehaviorAsString().

Returns:

The match status to assign to the web request if the request doesn't have a JA3 fingerprint.

You can specify the following fallback behaviors:

• MATCH - Treat the web request as matching the rule statement. WAF applies the rule action to the request.

• NO_MATCH - Treat the web request as not matching the rule statement.

fallbackBehaviorAsString

public final String fallbackBehaviorAsString()

The match status to assign to the web request if the request doesn't have a JA3 fingerprint.

You can specify the following fallback behaviors:

• MATCH - Treat the web request as matching the rule statement. WAF applies the rule action to the request.

• NO_MATCH - Treat the web request as not matching the rule statement.

If the service returns an enum value that is not available in the current SDK version, fallbackBehavior will return FallbackBehavior.UNKNOWN_TO_SDK_VERSION. The raw value returned by the service is available from fallbackBehaviorAsString().

Returns:

The match status to assign to the web request if the request doesn't have a JA3 fingerprint.

You can specify the following fallback behaviors:

• MATCH - Treat the web request as matching the rule statement. WAF applies the rule action to the request.

• NO_MATCH - Treat the web request as not matching the rule statement.
