What’s new in Calico Enterprise 3.14: WAF, Calico CNI on AKS, and support for RKE2
At Tigera, we strive to innovate at every opportunity thrown at us and deliver what you need! We have listened to what users ask and today we are excited to announce the early preview of Calico Enterprise 3.14. From new capabilities to product supportability and extending partnerships with our trusted partners, let’s take a look at some of the new features in this release.
Web application firewall (WAF)
Web applications are a critical aspect of any business, whether they are public facing or internal. There has been a fundamental shift in the way these applications are developed—as they have become more container-based and API-based, we refer to these as cloud-native applications.
To keep these modern web applications secure, we need to analyze all HTTP communication and block any malicious traffic traversing the web application. However, in a cloud-native environment, we can’t achieve this using simple network policies or by using perimeter network firewalls. Instead, a cloud-native web application firewall (WAF) would be necessary.

This is why we have introduced a cloud-native WAF into Calico Enterprise that’s different from the traditional WAFs you may know. While most traditional WAFs are deployed Continue reading
HS025 Did You Know Your IT is a Crime Scene ?
Does planning for cybersecurity failure include the concept of 'crime scene' ? Can you provide evidence to an external investigation sufficient to get justice or simply prove to insurance investigator that you met the policy requirements ? Should you be lobbying governments ? How does this drive your cyber spending - defense, microsegmentation, detection or evidence collection ?

OSPF Router IDs: Do They Actually Have To Be Unique?
This article uses the example of duplicate Router IDs to explore the distribution of Link State Advertisements (LSAs) in the OSPF routing protocol. It covers multiple types of LSAs, Area Border Routers, and more.

Making Data Centers Cool Again
As compute power in data centers increases, so too, does cooling requirements. Some of the biggest providers in the world are beginning to look to liquid immersion to keep their systems cool and working.Let’s celebrate the 8th anniversary of Project Galileo!
This post is also available in 日本語, Deutsch, Français, Español and Português.
We started Project Galileo in 2014 with the simple idea that organizations that work in vulnerable yet essential areas of human rights and democracy building should not be taken down because of cyber attacks. In the past eight years, this idea has grown to more than just keeping them secure from a DDoS attack, but also how to foster collaboration with civil society to offer more tools and support to these groups. In March 2022, after the war in Ukraine started, we saw an increase in applications to Project Galileo by 177%.
Read ahead for details on all of our eighth anniversary announcements:
- Two new civil society partners helping choose participants
- New insights on attack patterns using data from Cloudflare Radar
- A portal designed to ease onboarding for Galileo participants
- Details on our sessions at RightsCon this week
- New case studies highlighting Galileo participants and the important work they are doing
Announcing two new Project Galileo partners
This year, we are excited to welcome two new partners, International Media Support and CyberPeace Institute. As we introduce new partners, we are able to expand the project Continue reading
MLAG Deep Dive: Dynamic MAC Learning
In the first blog post of the MLAG Technology Deep Dive series, we explored the components of an MLAG system and the fundamental control plane requirements.
This post focuses on a major building block of the layer-2 data plane functionality: MAC learning. We’ll keep using the same network topology with two switches and five hosts, and assume our system tries its best to implement hot-potato switching (sending the frames toward the destination MAC address on the shortest possible path).
