Kubernetes Security for Developers

Kubernetes secures nothing by default. The service account token is auto-mounted into every pod, every pod can reach every other pod in the cluster, and a wildcard ClusterRole

Cloud Security for Developers

The average time to detect a cloud breach is over 200 days, and most of those breaches started not with a sophisticated exploit, but with a misconfigured permission or an exposed credential. Cloud providers secure the infrastructure. You secure everything you deploy on it. This course covers the insecure configurations that cause real-world cloud breaches

Fuzzing with AI

Fuzzing finds the vulnerabilities that code review, security tests, and static analysis miss -- the ones that only surface under inputs no developer would write by hand.

StackOverflow Outage

In June 2016, StackOverflow servers were unresponsive for more than 30 minutes. The issue was related to a security bug that was triggered by a malicious post. The post, which was displayed on the homepage, caused excessive CPU usage and delayed the page's response. Let's find out what the security bug was, how to detect it, and how to address it in our code.
