Kubernetes is a valuable resource and a leading container management system in development pipelines across the world, but it’s not exempt from malicious attacks. Using Kubernetes requires a deep understanding of Kubernetes’ environment—including the different vulnerabilities you can be exposed to while creating, deploying, or running applications in your clusters.
In the last few years, Kubernetes has grown exponentially in popularity. Its wide adoption can be attributed to its open source nature, flexibility, and ability to run anywhere. Developers also love the fact that you can manage everything in Kubernetes using code. kubectl is the Kubernetes-specific command line tool that lets you communicate and control Kubernetes clusters. Whether you’re creating, managing, or deleting resources on your Kubernetes platform, kubectl is an essential tool.
OpenSSH ProxyJump and ProxyCommand directives tell the SSH client how to connect to a remote server via an intermediary server — often called a jump host, jump server, or bastion server. If you are new to jump servers, read our tutorial on how to set up a jump server and learn some of the best practices to secure them.
Our previous blog post on authentication security covered six most common authentication vulnerabilities. In this post, we will discuss a few best practices that help avoid authentication vulnerabilities and defeat specific attack vectors. Below are the six best practices to secure the authentication process.
One of the most exciting things about working at Teleport is getting to see how our infrastructure access solutions enable customers to grow their business. Since software has eaten the world, solutions like Teleport that enable developers to become more productive are essential to fast- growing companies. You simply can’t create a hyper growth business today without a strong software development muscle.
The majority of threats related to the authentication process are associated with passwords and password-based authentication methods. But broken authentication also causes a significant amount of vulnerabilities. Broken authentication occurs when the implementation of the authentication process is flawed. Unfortunately, this is usually hard to discover, and can be more severe than the risks associated with passwords.
Authentication, authorization, and accounting, often called AAA or Triple-A, are sets of services and protocols that enable granular access control over computer networks. Before the popularity of mainstream HTTP-based authentication protocols such as OAuth and SAML, AAA protocols were the primary way to authenticate users or machines to network services.
Kubernetes is an API-centric orchestration platform. Every request, from the cluster components to users interacting with the system, has to go through the API server. The API server is a component in the control plane, and acts as a gatekeeper for the operation requests originating from both inside and outside of the cluster.
