No matter how you slice it, the use of containers and Kubernetes continues to swell. And recent high profile vulnerabilities-that-shall-not-be-named have shown us how important container security is for an overall application security program. Protecting your own code, your dependencies, and the containerized services you use are all a must.
Fairwinds Insights is Kubernetes governance and security software that enables DevOps teams to monitor and prevent configuration problems in their infrastructure and applications. Not only does Fairwinds simplify Kubernetes complexity, but it also reduces risk by surfacing security and reliability issues in your Kubernetes clusters.
Without a doubt, Kubernetes is the most prominent container orchestration tool. And you’ve probably noticed that many positions available to IT professionals require Kubernetes experience. One way to gain or prove your Kubernetes knowledge is by becoming a Certified Kubernetes Administrator (CKA). This certification is issued by the Cloud Native Computing Foundation (CNCF) in collaboration with the Linux Foundation. They offer three Kubernetes related certifications.
GKE Autopilot from Google Cloud is a mode of operation in Google Kubernetes Engine (GKE) designed to simplify working with Kubernetes in the cloud. Pairing secure DevOps practices with GKE Autopilot will help you and your teams ensure the security, compliance, and performance of your workloads and applications. Sysdig has collaborated with Google Cloud to enable visibility and security for GKE Autopilot and your containers.

Previously, we discussed the vulnerability and how to find it in your images using Sysdig Scanning reports. In a perfect world, patching would be quick, easy, and completed without any issues.
On Dec 9th, a critical zero-day vulnerability - CVE-2021-44228 - was announced concerning the Java logging framework - Log4j All current versions of log4j2 up to 2.14.1 are vulnerable. To remediate this vulnerability, please update to version 2.15.0 or later.
Audit logging involves recording transactions and system events, making it an invaluable tool for regulatory compliance, digital forensics, and information security. In a typical Kubernetes ecosystem, auditing involves providing chronological, activity-relevant records documenting events and actions in a cluster. Modern logging tools come with aggregation and analytical functionalities so that teams can use log data to mitigate security threats.
The Sysdig Threat Research Team has detected an attack that can be attributed to the TeamTNT. The initial target was a Kubernetes pod exposed outside the network. Once access was gained, the malware attempted to steal AWS credentials using the EC2 instance metadata. TeamTNT is a threat actor that conducts large-scale attacks against virtual and cloud solutions, like Kubernetes and Docker.
