Container Security — From Image Analysis to Network Segmentation, Options Are Maturing

Published: 28 August 2018

Summary

Containers and microservices architectures require DevSecOps, a protection strategy different from traditional VMs with monolithic applications. Technical professionals tasked with securing containers must harden the CI/CD pipeline so that everything that ran through it can be considered secure.
