Use log auditing so that administrators can monitor activity and be alerted to potential malicious activity.

Use strong authentication and authorization to limit user and administrator access and limit the attack surface.

Use firewalls to limit unneeded network connectivity and encryption to protect confidentiality.

Use network separation to control the amount of damage a compromise can cause.

Run containers and pods with the least privileges possible.

Scan containers and pods for vulnerabilities or misconfigurations.

With the ever-changing technology landscape, it’s hard for organizations and teams to keep up with securing Cloud and container environments, as doing so requires them to understand the latest technology prior to solving security problems.” In the wake of the Colonial Pipeline ransomware outbreak and other recent supply chain attacks, the US National Security Agency (NSA) and the Cybersecurity and Infrastructure Security Agency (CISA) have released Kubernetes hardening guidance which includes various tips and best practices for securing Kubernetes. The recent Red Hat State of Kubernetes Security Report states that 94% of respondents experienced at least one security incident in their Kubernetes environments in the last 12 months, and concludes that security misconfigurations are to blame for the majority of these issues.” He elaborates, “These past few months have shown that supply chain attacks have serious implications when it comes to the security of modern infrastructure, as everything is codified including policies, infrastructure, applications - even security. In an recent interview with LinuxSecurity, Cloud Native Security Architect and instructor of the Black Hat USA 2021 course A Practical Approach to Breaking & Pwning Kubernetes Clusters Madhu Akula explained, “The challenges we see mostly arise from misconfiguration issues, which can have a big impact like the compromise of data and infrastructure. Cloud and container adoption is rapidly increasing, as these technologies and frameworks enable organizations to grow and evolve at a very high velocity compared to the traditional workloads.
