![]() ![]() As an example, we restrict public connectivity to our Ingress nodes (that will deploy Envoy ingress gateways). Within each VPC, Network ACLs and Security Groups are set up to restrict connectivity to what is absolutely required. Additionally, this pattern avoids the possibility of RFC 1918 private IP exhaustion when leveraging many clusters. This keeps Pods and Nodes from separate clusters completely isolated, while allowing traffic outside the cluster to have particular rules enforced in the public and internal subnets. Securing Layer 3/4: AWS, Aviatrix and KubernetesĪt Splunk Cloud, we use a pattern called “cookie cutter VPCs” where each cluster is provisioned with it’s own VPC, with identical private subnets for Pod and Node IPs, a public subnet for ingress and egress to and from the public internet, and an internal subnet for traffic between clusters. Today Splunk Cloud consists of over 35 fully replicated clusters in AWS and GCP in regions around the world. Splunk Cloud is an initiative to move Splunk’s internal infrastructure to a cloud native architecture. It is primarily used for searching, monitoring, and analyzing machine-generated big data through a web-style interface. Splunk is a technology company that provides a platform for collecting, analyzing and visualizing data generated by various sources. Splunk uses a variety of tools to secure their network, including: Along the way, we’ll see what it takes to provide comprehensive network security for your cloud native stack, how these tools interoperate, and where some of them can improve. This post will explore the tools and practices leveraged by Splunk to secure their Kubernetes network infrastructure, starting with VPC design and connectivity and going all the way up the stack to HTTP Request based security. How many tools do you need? When is your network secure enough? What is often less clear is how these tools interoperate to provide comprehensive security for your network in production. With dozens of tools for securing your network available, it is easy to find tutorials and demonstrations illustrating how these individual tools make your network more secure by adding identity, policy, and observability to your traffic. ![]()
