Link-Local Multicast Name Resolution (LLMNR) and NetBIOS Name Service (NBT-NS) are two protocols that are used to identify a host address on a network when the DNS name resolution, which is the conventional method, fails to do so. When a DNS server is unable to resolve a request from a requester machine, the latter broadcasts a message to its peer computers asking for the location of the required server. Hackers leverage this operation to steal the credentials of the requester machine.

From smart thermostats and grocery store checkouts to public utility infrastructures and industrial manufacturing lines, the Internet of Things (IoT) is all around us—and growing larger every day. But with this rapid growth comes a number of operational challenges: IoT devices collect a large amount of data, and are often distributed across harsh, ever-changing environments.

Kubernetes has a lot of features and deployment options for running containers. One of these is the StatefulSet. In this blog post, we’ll discuss what a StatefulSet is, what it can be used for, and how to create and update them.

A new vulnerability, CVE-2020-8557, has been detected in kubelet. It can be exploited by writing into /etc/hosts to cause a denial of service. The source of the issue is that the /etc/hosts file mounted in a pod by kubelet is not included by the kubelet eviction manager, so it’s not taken into account when calculating ephemeral storage usage by a pod.

Cortex and Thanos are two brilliant solutions to scale out Prometheus, and many companies are now running them in production at scale. These two projects, both in the CNCF Sandbox, initially started with different technical approaches and philosophies: Cortex has been designed for scalability and high performances since day zero, while Thanos was originally focused on operational simplicity and cost-effectiveness.

Strategic changes and new deployments in all growing businesses are expected. So by design, businesses need to be adaptive to new changes. When such transformations are being undertaken, organizations need to continue preserving their infrastructures while complying with pre-defined timelines. To efficiently manage such deployments, organizations make use of ITIL concepts like change and release management.
