Red Hat Advanced Cluster Security for Kubernetes

Microservices deployment in Kubernetes demands higher-level security needs and perception. The non-functional requirements of Microservices are unfolding in a complex manner. The two least focused areas in a Software Development Life Cycle are ‘Security’ and ‘Performance’.

Consider Development is on the ‘left’ and Operations is at the ‘right’. It is important to shift the security to the left; Therefore, organizations can enjoy the speed to market practice of DevOps to release their applications securely and stay competitive.

DevSecOps is the practice to enable the ‘shift security to the left’ concept. It is a collaborated automation framework that integrates Development, Operations and Security by adding security practices to the software development lifecycle at the development stage itself.

Red Hat and StackRox

Red Hat is the leader in DevOps and DevSecOps. They recently acquired StackRox, a California-based Kubernetes security company that concentrates on runtime security for Containers and Kubernetes. The acquisition strengthened Red Hat security portfolio in the Container market and complements Red Hat OpenShift by bringing critical security capabilities.

Paul Cormier, CEO of Red Hat said, ‘Securing Kubernetes workloads and infrastructure cannot be done in a piecemeal manner; security must be an integrated part of every deployment, not an afterthought.’

Advantages of StackRox Acquisition

The integrated DevOps and DevSecOps product model (Red Hat OpenShift + StackRox) provide the following benefits to the customers.

Technical support for Kubernetes and Security products

For those looking to secure complex environments, a customer needs a stable technical support from product vendors. With the StackRox acquisition, Red Hat will be able to further expand its Hybrid Cloud security leadership and reinforce their commitment to deliver a single, comprehensive platform for users to build, and deploy applications more securely across the Hybrid Cloud.

The Modern Shift-Left Security Strategy

A shift-left approach shifts initial security responsibilities to developers. A developer can catch vulnerabilities and misconfigurations before they are exploited to reduce the risk of breaches in production.

Integrated Orchestration

Integrated OpenShift Orchestration and StackRox Security platform to enable the application to utilize the best of the breed security practices. Detects and contain attacks and orchestrate Containers efficiently.

Hybrid Cloud Security

Several organizations choose one security platform and strategy for their private cloud and a different one for their public cloud, with the two often not being compatible with each other. Ideally, security and development teams need a unified platform that can simultaneously secure both environments while still providing an unfettered look at all traffic, and addressing the above-mentioned items. Red Hat bridges the gap.

Out of the box vulnerability and security scanning capabilities

With the StackRox acquisition and its complementary capabilities to strengthen integrated security across Red Hat Open Hybrid Cloud portfolio with greater simplicity and consistency, combined with the above-described advantages, Red Hat will further expand its ‘Security Leadership’.

StackRox is Red Hat Advanced Cluster

Security for Kubernetes.
