Kubernetes Admission Controller is an advanced plugin for gating and governing the configuration changes and workload deployment in a cluster. Admission Controller enables DevOps and Security personnel to enforce deployment requirements and restrictions in the cluster upon every workload start and any configuration change. Think of an Admission Controller as an Advanced Resource manager with a shield.

Every compliance audit will ask you to secure SSH, and every time a scanner checks the configuration or CSPM of your cloud account you’ll be warned for it. For example, if you don’t secure SSH on EC2, you’ll certainly get a critical alert stating that one of your Security Groups has its SSH port (22) open to the world. When this happens, you may think: Have I been pwned?

As organizations transition from monolithic services in traditional data centers to microservices architecture in a public cloud, security becomes a bottleneck and causes delays in achieving business goals. Traditional security paradigms based on perimeter-driven firewalls do not scale for communication between workloads within the cluster and 3rd-party APIs outside the cluster.

Kubernetes pods are the basic building blocks of Kubernetes. It's managing one or more tightly coupled application containers allowing them to share resources and networks. Pods are hosted on nodes, which are either physical or virtual machines. When defining a Pod we need to think not only about how much CPU or memory we want to assign to it but also about what would be the interaction between it and the underlying infrastructure.

Elastic Compute Cloud (EC2) is arguably one of the most popular AWS services, and really needs no introduction but here is one anyway. With Sysdig, you can secure EC2 by managing configuration and permissions risk, meeting compliance requirements, and managing vulnerabilities on containers and host VMs. When it comes to EC2 and Hosts themselves, Sysdig Secure alerts us in multiple ways.

Kubecon EU returned to Spain. This time to Valencia, city of paella and horchata and, of course, a great place for big events. We had a great time meeting you all in person, and attending the talks. Here are our hot takes from the event. The main event started on Wednesday, but before that different co-located events took place: Ebpf Day, Cloud Native SecurityCon, and PrometheusDay among others. These events gathered a large number of attendees.
