Every cloud has its own identity and access management system. AWS and Google use a bunch of JSON files specifying various rules. Open source projects like Kubernetes support three concurrent access control models - attribute-based, role-based and a webhook access control, all expressed using YAML. Some teams are going as far as inventing their own programming language to solve this evergreen problem.

Cross-site scripting (XSS) is an attack that allows JavaScript from one site to run on another. XSS is interesting not due to the technical difficulty of the attack but rather because it exploits some of the core security mechanisms of web browsers and because of its sheer pervasiveness. Understanding XSS and its mitigations provides substantial insight into how the web works and how sites are safely (and unsafely) isolated from each other.

SSH certificates, when deployed properly, improve security. A half-baked access system using certs is more vulnerable than a public-key-based one if a user or host gets hacked.

It seems like nowadays, every company is a SaaS company. We’ve even begun stratifying by what is sold, replacing the “software” in SaaS to whatever the product’s core competency is, search-as-a-service, chat-as-a-service, video-as-a-service. So, when we, at Teleport, set sail for the cloud after years of successfully navigating on-prem software, we came in with a different set of experiences.
