Organizations are transitioning into the cloud at warp speed, but cloud security tooling and training is lagging behind for the already stretched security teams. In an effort to bridge the gap from endpoint to cloud, teams are sometimes repurposing their traditional endpoint detection and response (EDR) and extended detection and response (“XDR) on their servers in a “good enough” approach.

In the age of cloud computing, where more and more virtual hosts and servers are running some flavor of Linux distribution, attackers are continuously finding innovative ways to infiltrate cloud systems and exploit potential vulnerabilities. In fact, 91% of all malware infections were on Linux endpoints, according to a 2023 study by Elastic Security Labs.

Over the past year, we’ve been building something new for Calico Cloud that’s aimed at helping anyone who is charged with improving the security of their Kubernetes clusters. I’m excited to announce that Calico Cloud is releasing new capabilities for security posture management called Security Scoring and Recommended Actions.

In my previous blog post, I touched upon some challenges with how NGFW container firewalls are built and how it takes a team of firewall specialists to deploy, configure and maintain the firewall platform. In this blog I will illustrate the challenges in detail and demonstrate the simplicity of the Calico container firewall platform.

Considering the vast attack surface and flat network architecture, Kubernetes workloads are particularly susceptible to network-based threats. While following best practices like workload access controls, workload-centric IDS/IPS, and WAF can help prevent and block attacks, anomaly detection has become crucial in today’s IT landscape to proactively anticipate security threats.

Many AWS customers have security requirements that are well beyond what AWS Security Groups or AWS Network Access Control Lists can offer in terms of scalability and security. That’s why many of them turn to AWS Network Firewall as a common solution.

While Kubernetes adoption continues to soar, it has become a prime target for cyberattacks. Unfortunately, Kubernetes clusters are complex and can be difficult to secure. Safeguarding your Kubernetes environment requires a solid understanding of the common attack chains that pose a threat to your infrastructure. In this blog post, we dig into the top attack chains that target Kubernetes, shedding light on the risks and offering valuable insights to bolster your defenses.

The timeline of an application can be broadly described in 3 phases: Thus, runtime security in the context of a cloud-native container environment broadly refers to the tools and processes leveraged to protect the operation of running containers in production.

Containers offer a streamlined application deployment and management approach. Thanks to their efficiency and portability, platforms like Docker and Kubernetes have become household names in the tech industry. However, a misconception lurks in the shadows as containers gain popularity - the belief that active vulnerability scanning becomes redundant once containers are implemented.
