Today, I’m excited to announce the contribution of the sysdig kernel module, eBPF probe, and libraries to the Cloud Native Computing Foundation. The source code of these components will move into the Falco organization and be hosted in the falcosecurity github repository. These components are at the base of Falco, the CNCF tool for runtime security and de facto standard for threat detection in the cloud.
Image vulnerability scanning is a critical first line of defense for security with containers and Kubernetes. Today, Red Hat recognized Sysdig as a certified Red Hat security partner based on our work to standardize on Red Hat’s published security data with Sysdig Secure.
Runtime security for Azure Kubernetes Service (AKS) environments requires putting controls in place to detect unexpected and malicious behavior across your applications, infrastructure, and cloud environment. Runtime threats include things like: Even if you’re taking advantage of tools like container image vulnerability scanning, Kubernetes pod security policies, and Kubernetes network policies with AKS, not every risk will be addressed.
As Kubernetes adoption continues to grow, Kubernetes audit logs are a critical information source to incorporate in your Kubernetes security strategy. It allows security and DevOps teams to have full visibility into all events happening inside the cluster. The Kubernetes audit logging feature was introduced in Kubernetes 1.11.
The defense evasion category inside MITRE ATT&CK covers several techniques an attacker can use to avoid getting caught. Familiarizing yourself with these techniques will help secure your infrastructure. MITRE ATT&CK is a comprehensive knowledge base that analyzes all of the tactics, techniques, and procedures (TTPs) that advanced threat actors could possibly use in their attacks. Rather than a compliance standard, it is a framework that serves as a foundation for threat models and methodologies.
A recent privilege escalation heap overflow vulnerability (CVSS 7.8), CVE-2021-3156, has been found in sudo. sudo is a powerful utility built in almost all Unix-like based OSes. This includes Linux distributions, like Ubuntu 20 (Sudo 1.8.31), Debian 10 (Sudo 1.8.27), and Fedora 33 (Sudo 1.9.2). This popular tool allows users to run commands with other user privileges.
In this blog, we will compare and contrast Falco vs. AuditD from a Host Intrusion Detection (HIDS) perspective. AuditD is a native feature to the Linux kernel that collects certain types of system activity to facilitate incident investigation. Falco is the CNCF open-source project for runtime threat detection for containers and Kubernetes. We will dig deeper into the technical details and cover the installation, detection, resource consumption, and integration between both products.
The fourth annual Sysdig container security and usage report looks at how global Sysdig customers of all sizes and industries are using and securing container environments. By examining how and when organizations are implementing security in the development lifecycle, we have been able to uncover some interesting data points in this year’s report. For example, we can see that 74% of organizations are scanning container images in the build process.
