The network is foundational to distributed application environments. A distributed application has multiple microservices, each running in a set of pods often located on different nodes. Problem areas in a distributed application can be in network layer connectivity (think network flow logs), or application resources unavailability (think metrics), or component unavailability (think tracing).
Companies are leveraging the power of Kubernetes to accelerate the delivery of resilient and scalable applications to meet the pace of business. These applications are highly dynamic, making it operationally challenging to securely connect to databases or other resources protected behind firewalls.
Kubernetes has become the world’s most popular container orchestration system and is taking the enterprise ecosystem by storm. At this disruptive moment it’s useful to look back and review the security threats that have evolved in this dynamic landscape. Identifying these threats and exploits and being a proactive learner may save you a lot of time and effort…as well as help you retain your reputation in the long run.
