Container Security Essentials: Vulnerability Scanning and Change Detection Explained

Containers offer a streamlined application deployment and management approach. Thanks to their efficiency and portability, platforms like Docker and Kubernetes have become household names in the tech industry. However, a misconception lurks in the shadows as containers gain popularity - the belief that active vulnerability scanning becomes redundant once containers are implemented.

What you can't do with Kubernetes network policies (unless you use Calico): Node Specific Policies

In my previous blog post, What you can’t do with Kubernetes network policies (unless you use Calico): TLS Encryption, I talked about use case number two from the list of 9 things you cannot implement using basic Kubernetes network policy—anything TLS related. In this blog post, we’ll be focusing on use case number three: node specific policies.

The new standard of Kubernetes misconfiguration remediation

According to research done by ARMO, 100% of Kubernetes clusters that were tested contained at least one misconfiguration, while 65% had at least one high-severity misconfiguration. 50% of clusters had 14 or more failed security controls. According to Redhat research from 2023, 45% of respondents experienced security incidents or issues related to containers and/or Kubernetes due to misconfigurations.

Ensuring robust security of a containerized environment

In today’s rapidly evolving digital landscape, containerized microservices have become the lifeblood of application development and deployment. Resembling miniature virtual machines, these entities enable efficient code execution in any environment, be it an on-premises server, a public cloud, or even a laptop. This paradigm eliminates the criteria of platform compatibility and library dependency from the DevOps equation.

Detecting Network-Based Anomalies with Calico

In the vast digital landscape, the flow of data across networks is akin to water coursing through a city’s plumbing system. Just as impurities in water can signal potential issues, deviations in network traffic, termed as network inserted anomalies, can hint at cyber threats. These anomalies range from overt signs like unauthorized access attempts to subtler indicators like unusual data transfer patterns.
