AWS WAF has introduced support for customizable evaluation time windows in request aggregation with rate-based rules. You now have the flexibility to choose time windows of 1 minute, 2 minutes, or 10 minutes, expanding on the previously available 5-minute option. Prior to this update, AWS WAF users could utilize rate-based rules to tally incoming requests and impose rate limits on those surpassing the specified rate threshold. The system previously employed a fixed 5-minute window for aggregating requests when evaluating rules. With the new enhancement, you can now opt for 1 minute, 2 minutes, or 10-minute time windows, in addition to the existing 5-minute window, offering adaptability based on the specific needs of their applications. A shorter evaluation window may be more effective for swiftly identifying and blocking spikes in high-traffic applications, while a longer window might be better suited for applications with less frequent access.
Amazon WorkSpaces has incorporated support for the WebAuthn (Web Authentication) standard to enhance in-session authentication. Users can now authenticate themselves into web applications supporting WebAuthn through redirection when using Chrome or Edge on their Windows WSP WorkSpaces. This functionality is available across WorkSpaces Windows, macOS, and Linux client applications, and it is compatible with various authenticators such as YubiKey, Windows Hello, and other FIDO2-compliant devices. Organizations can utilize this updated standard to fortify security measures, preventing unauthorized access to sensitive company data on WorkSpaces.
