Kubernetes protection has grow to be the focal issue for guarding cloud-indigenous workloads among enterprises as they deploy containers and microservices in creation.
In the beginning, container protection specialists such as Aqua, Twistlock and StackRox concentrated on scanning container photos inside the DevOps pipeline, then extra container runtime scans for stay creation environments by brokers deployed on person hosts.
Extra not long ago, nevertheless, such equipment have shifted their concentration to the total Kubernetes system, adding network-primarily based protection controls and coverage-pushed mechanisms. A new crop of players such as Octarine has also emerged they plug in to the network service mesh layer of Kubernetes atmosphere to deepen protection visibility.
This craze demonstrates escalating maturity at enterprise firms as they handle the far-achieving protection implications of deploying microservices by way of Kubernetes.
“With microservices and containers in normal, you can find opportunity to multiply your protection threat exponentially, and they multiply the amount of details [in the infrastructure] that will need to be analyzed,” stated Jason Harris, VP of cloud architecture at Aptos, an Atlanta-primarily based computer software maker for stores. “Kubernetes is our indicates of offering microservices, and we’re hunting at it as a way to deploy apps securely as well.”

Aptos to start with rolled out container-primarily based microservices in support of their customers’ retail issue-of-sale (POS) techniques in late 2018. But in the latter fifty percent of 2019, Aptos began to glance for a resource that could precisely automate Kubernetes protection. It reviewed items from Aqua, Twistlock, Qualys and StackRox, and ultimately selected StackRox.
The StackRox resource beat out incumbent IT protection seller Qualys, which has characteristics for container impression scanning, mainly because of its concentration on container runtime protection in the context of the Kubernetes system, Harris stated. Some Qualys container runtime characteristics are nonetheless in beta.

“Microservices are genuinely levels of containers that deliver a service, and these comprise open up source parts or there may be rogue containers,” Harris stated. “[In] Kubernetes in normal, [means] shift, and that is the place StackRox provides benefit: hunting into Kubernetes in addition to the containers.”
The StackRox approach to Kubernetes protection integration was a further advertising issue for Aptos in excess of competition that also offer container runtime scanning, such as Twistlock and Aqua. StackRox deploys as a privileged DaemonSet inside Kubernetes clusters, which Aptos favored as a less difficult approach to Kubernetes protection set up.
“When we deploy a new cluster, it is just wrapped into that approach,” Harris stated. “Once you build that DaemonSet in the cluster, any new nodes are likely to inherit the daemon routinely.” The a lot more sophisticated substitute would call for StackRox to be deployed as a privileged container on each and every host.
People of Kubernetes protection items primarily based on host brokers deploy them to nodes routinely by infrastructure as code (IaC) equipment such as Terraform, but StackRox also available powerful visibility into Kubernetes cluster configuration. This has served Aptos with regulatory compliance in addition to Kubernetes protection, since it can very easily demonstrate auditors a comprehensive perspective of its atmosphere.
“StackRox not long ago extra a configuration management app that we’ve gotten far a lot more benefit out of than we envisioned, mainly because it is turning into a excellent reporting resource on our Kubernetes ecosystem,” Harris stated. “It truly is really hard to have visibility into just even very simple items like the amount of clusters [in creation] and the amount of nodes [inside them], and what is my Kubernetes version on all these clusters?”
Issues in Kubernetes protection and protection for microservices remain, as cloud-indigenous technology carries on to evolve at breakneck speed and retail consumers demand from customers microservices-primarily based mobile apps. This sort of apps will call for Aptos to support publicly hosted mobile app keep APIs and shopper payment info, upping the microservices protection stakes.
Any form of alter offers protection hazards, but as with other enterprise container customers, Aptos believes the blend of IaC automation for Kubernetes deployment and coverage-primarily based Kubernetes protection automation increases its protection posture in excess of equipment it used with regular monolithic apps.
“The visibility and the manage we have in this planet far outweighs the drift that you experienced in the older planet,” Harris stated. “I am going to choose the difficulties in the new planet any day in excess of our legacy difficulties.”
While Kubernetes protection was the primary advertising issue for StackRox, Harris stated he is hunting forward to future advancements in the tool’s container scanning characteristics for photos inside container registries, which has lagged that of some other container protection specialists and container registry equipment such as Red Hat Quay.
“The perspective we needed was, ‘OK, demonstrate me this vulnerability across all my photos, and if I flip to an impression, demonstrate me any vulnerabilities over a specific level,'” he stated. “Hopefully, we are going to get there quickly.”
A StackRox characteristic that demonstrates vulnerabilities in container photos inside a registry, like their severity level, was previewed at KubeCon in November, and will grow to be generally readily available this month, a firm spokesperson stated.
