Learn how to expose TCP ports using Istio Ingress Gateway in Kubernetes. This guide covers the steps to configure Istio for TCP traffic, including practical use cases like exposing TIBCO EMS servers, databases, and custom TCP services.
In today’s digital landscape, ensuring server security is paramount. Learn about “Server Information Disclosure” and how Istio Service Mesh can mitigate this vulnerability. Explore examples of server headers and see how to remove them for improved security. Discover the power of Istio in enhancing server protection and fortifying your defense against cyber threats.
Discover how Istio’s Proxy DNS capability enhances service mesh DNS resolution, offering advanced service discovery, load balancing, security, and traffic management. Learn about the benefits and use-cases of leveraging Istio’s Proxy DNS to simplify and optimize communication between microservices in complex architectures
Istio’s Security Policies, comprising PeerAuthentication, RequestAuthentication, and AuthorizationPolicy objects, fortify the security of microservices in a service mesh environment. PeerAuthentication enforces mutual TLS authentication, while RequestAuthentication enables fine-grained control over incoming request authentication, supporting mechanisms like JWT validation and API key authentication. The AuthorizationPolicy object facilitates granular access control, empowering administrators to define rules based on source, destination, headers, and payload attributes. Discover how Istio’s Security Policies enhance security, prevent unauthorized access, and establish secure communication within your service mesh architecture.

An Istio ServiceEntry is an object within the Istio service mesh that allows you to extend the mesh to external endpoints or internal services that are not part of the platform’s service registry. ServiceEntries allow you to specify details such as hostname, port, and protocol for the external service, as well as the resolution mode to use when accessing it. You can use ServiceEntries to apply Istio features such as load balancing, protocol switching, and authentication to external services. You can also view ServiceEntries in the Kiali graphical representation of the service mesh. ServiceEntries are useful in a variety of scenarios, including when you want to connect to external services or when you have multiple clusters and need to extend the mesh across them.

Looking to secure the communication between services in your Kubernetes cluster with Istio? In this article, we’ll provide a step-by-step guide on how to establish a Transport Layer Security (TLS) connection with Istio. We’ll cover how to expose TLS on the Istio ingress gateway, consume SSL from Istio, and enforce mutual TLS (mTLS) between different services in the cluster. By following the instructions in this guide, you can ensure secure communication and protect your applications from cyber threats. With Istio, you can easily centralize and externalize security aspects, allowing your applications to focus on their business logic and reducing the workload on your development team.
Looking to improve the observability and management of your Istio service mesh? Kiali is here to help. As an open-source project developed by Red Hat, Kiali provides a graphical representation of your mesh, displaying the relationships between service mesh components and key metrics like request and error rates. It also includes tools for monitoring the health of your mesh and troubleshooting issues with service communication. In addition to its observability features, Kiali offers a traffic management module and a configuration management module to help you manage your mesh. Learn how to install and use Kiali to maximize the performance of your service mesh.
