Google Unveils New Capabilities for Cloud Armor Web Security Service

Google today announced a new set of features for Cloud Armor, its distributed denial of service (DDoS) mitigation service and web application firewall (WAF).

Using the same infrastructure and technology that Google relies on to keep its Internet resources secure, Cloud Armor became generally available in 2019 to keep customer resources safe from DDoS attacks, regardless of whether they are on-premises or in the cloud. .

Today, Google announced the general availability of Cloud Armor features such as per-customer rate capping, bot management with reCAPTCHA Enterprise, and adaptive protection based on machine learning.

The new rate limiting feature allows customers to restrict traffic to back-end resources based on request volume, preventing resource exhaustion and service interruption. Cloud Armor for TCP/SSL Proxy allows users to limit speed at the connection level as well.

Rate limiting comes with two types of rules, namely throttling – clients can throttle traffic on a per-client basis, up to a user-configured threshold, and rate_based_banning – in addition to rate limiting requests or connections that match a specific rule, customers can also ban customers for specific time periods.

Cloud Armor rate limiting can be used to prevent brute force login attempts or to apply different rate limits per geography, depending on the number of customers in the region.

Bot management with reCAPTCHA Enterprise, introduced in preview last fall, protects customers from bot attacks, credential stuffing, inventory hoarding, scraping, and other types of threats.

The capability allows for more seamless testing (the user does not receive a reCAPTCHA challenge while the system is testing), but Cloud Armor users can also choose a more traditional manual challenge, or they can combine the two. Therefore, visitors may receive a reCAPTCHA challenge if a certain rule is triggered.

Initially introduced in July 2021, Adaptive Protection has been generally available since December 2021 and offers real-time detection and mitigation of suspicious Layer 7 traffic.

Today, Google also announced the preview availability of updated preconfigured WAF rules based on OWASP CRS 3.3, which enable customers to implement the latest industry-standard WAF signatures, and Google-selected network-based threat intelligence. which currently allows users to filter traffic based on bad bots, malicious IP addresses, public cloud endpoints, and Tor exit nodes.

Also today, Google announced new Cloud Armor capabilities that extend service protection to more types of workloads, namely perimeter security policies and support for TCP Proxy and SSL Proxy Load Balancers.

The new perimeter security policies are intended to help filter traffic before it is served from Cloud CDN and Media CDN caches, or from Cloud Storage buckets, and also allow users to apply user-based access controls. in geography, along with Google’s perimeter security policies. the net. Perimeter security policies can co-exist with back-end security policies.

Cloud Armor now also includes support for Google Cloud TCP/SSL proxy load balancers, which allow users to use Google’s load balancing infrastructure to serve encrypted workloads that use encrypted traffic (SSL and TLS), not HTTP. Cloud Armor customers can now use these capabilities to block and/or throttle potentially malicious traffic, or to enable per-connection rate limiting.

“With Cloud Armor, your organization can benefit from DDoS and WAF protection. Cloud Armor now helps detect and mitigate attacks against cache points and back-end service workloads, including those balanced by the external HTTP/S load balancer, as well as TCP and proxy load balancers. SSL. And these workloads can run anywhere: on premises, in colocation data centers, on Google Cloud, and on other cloud platforms.
