There is a growing discussion among network engineers, DevOps teams, and security professionals about the security benefits of bastions. Many assume that they are the “old way” of network access and have little relevance in the modern cloud native stack. These speculations are not irrelevant as in recent years, the corporate IT network perimeter as we knew it is diminishing, and the concept has been shifted to data, identity, and compute perimeter.

In April 2021, I discovered an attack vector that could allow a malicious Pull Request to a Github repository to gain access to our production environment. Open source companies like us, or anyone else who accepts external contributions, are especially vulnerable to this. For the eager, the attack works by pivoting from a Kubernetes worker pod to the node itself, and from there exfiltrating credentials from the CI/CD system.

What would you do when a security incident is detected? Shut down the servers? Pull out the power cord from the data center? When an incident is detected, both the incident method and the time required to contain an incident are essential to limit the damage. The slower you are to react, the more damage an incident would incur. And a service downtime to contain an incident can cost businesses even more than a security incident itself.

Do you have what it takes to become a cybersecurity expert? We interviewed 3 security professionals to find out how they got their start and what advice they would give to someone starting their career in cybersecurity. With security threats increasing, much of business continuity has come to rely on data security. In particular, engineering teams building cloud software rely on access to an ever-growing number of computing resources.
