Struct aws_sdk_wafv2::types::Ja3Fingerprint

#[non_exhaustive]
pub struct Ja3Fingerprint {
    pub fallback_behavior: FallbackBehavior,
}

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.

Fields (Non-exhaustive)

Non-exhaustive structs could have additional fields added in future. Therefore, non-exhaustive structs cannot be constructed in external crates using the traditional Struct { .. } syntax; cannot be matched against without a wildcard ..; and struct update syntax will not work.

fallback_behavior: 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.

Implementations

impl Ja3Fingerprint

pub fn fallback_behavior(&self) -> &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.

impl Ja3Fingerprint

pub fn builder() -> Ja3FingerprintBuilder

Creates a new builder-style object to manufacture Ja3Fingerprint.

Trait Implementations

impl Clone for Ja3Fingerprint

fn clone(&self) -> Ja3Fingerprint

Returns a copy of the value.

fn clone_from(&mut self, source: &Self)

Performs copy-assignment from source.

impl Debug for Ja3Fingerprint

fn fmt(&self, f: &mut Formatter<'_>) -> Result

Formats the value using the given formatter.

impl PartialEq for Ja3Fingerprint

fn eq(&self, other: &Ja3Fingerprint) -> bool

This method tests for self and other values to be equal, and is used by ==.

fn ne(&self, other: &Rhs) -> bool

This method tests for !=. The default implementation is almost always sufficient, and should not be overridden without very good reason.
