Many organizations are beginning out on their Kubernetes and container journey, whereas others are encountering complexity points as they scale out their deployments. Containerized purposes convey many advantages, but additionally introduce new sorts of safety challenges.
Uptycs reduces threat in your cloud and on-premises container workloads by prioritizing your responses to threats, vulnerabilities, misconfigurations, delicate knowledge publicity, and compliance mandates—all from a single platform, UI, and knowledge mannequin. Uptycs supplies risk detection for container runtimes correlated with Kubernetes management airplane assaults. The product additionally helps scanning of container pictures in registries for vulnerabilities, malware, credentials, secret keys, and different delicate data. These capabilities can be found for self-managed Kubernetes deployments in addition to for managed providers similar to Amazon Elastic Kubernetes Service, Azure Kubernetes Service, and Google Kubernetes Engine.
These Uptycs options help elevated coordination throughout groups, elimination of information silos for Kubernetes and container deployments, quicker risk detection and response occasions, and fast identification of dangers similar to misconfigurations and vulnerabilities.
eBPF on Linux container deployments
The idea for Uptycs container runtime observability is the prolonged Berkeley Packet Filter (eBPF) know-how. The Uptycs sensor makes use of eBPF to seize course of, file, and socket occasions within the Linux kernel. eBPF gives real-time safety observability, velocity, and comfort for monitoring extraordinarily high-volume occasion knowledge. eBPF is a protected means of interacting with the Linux kernel and a most well-liked different to plugging into the auditd framework. It’s also a just-in-time (JIT) compiler. After the bytecode is compiled, eBPF is invoked somewhat than a brand new interpretation of the bytecode for each technique.
With eBPF, Uptycs inserts probes into the Linux kernel to observe occasions of curiosity. This occurs when the sensor begins up and passes data again to the userland course of, drastically lowering the useful resource utilization wanted for in-depth safety monitoring. eBPF is well configured for this course of and doesn’t create any delays in deployment.
eBPF offers you a single, highly effective, and accessible unified tracing framework for tracing processes. Utilizing eBPF helps improve the function richness of an atmosphere with out including further layers. Likewise, as a result of eBPF code runs straight within the kernel, it’s attainable to retailer knowledge between eBPF occasions as an alternative of dumping it like different tracers do.
Container runtime risk detection
Scaling container deployments means extra ephemeral belongings for groups to safe and defend. Utilizing the detailed telemetry gathered by eBPF, Uptycs is ready to detect malicious habits in actual time, mapping detections to the Mitre Assault framework. Uptycs detects threats on working nodes and containers, capturing granular container and node telemetry overlaying course of occasions, file occasions, DNS lookups, socket occasions, and extra.
Information is normalized in actual time into SQL tables, making it seamless to kind advanced detection frameworks that string collectively a whole lot of alerts. Greater than 200 Yara guidelines scan binaries for malware signatures whereas 1,300-plus behavioral guidelines monitor for alerts from real-time occasion telemetry.
Locking down the Kubernetes management airplane
The Kubernetes management airplane is a high-value goal for attackers to compromise. From the management airplane attackers can create privileged containers, seize configuration requirements, and hop deeper into your cloud infrastructure. Uptycs captures greater than 50 tables of telemetry overlaying all Kubernetes objects throughout pods, deployments, configmaps, ingress, RBAC, and extra.
This telemetry supplies multi-cluster visibility into compliance, threats, and vulnerabilities by a single supply. From a macro view all the way down to a granular view into namespaces, pods, and workloads, Uptycs telemetry goals to reply any infrastructure questions from compliance visibility to runtime threats.
For instance, from a compromised Kubernetes management airplane, attackers will hunt for privileged containers or create privileged containers themselves. Uptycs displays for instructions for privileged pods being created in your Kubernetes clusters, stopping attackers throughout the course of of making these assaults and inspiring customers to construct immutable containers with just-right permissions somewhat than over-privileged deployments.
Unifying management airplane and knowledge airplane knowledge
Attackers don’t assume in silos, so it’s important that knowledge from completely different sections of Kubernetes infrastructure be correlated for tracing attacker actions. Risk actors are continuously trying throughout infrastructure, making an attempt container escape assaults. Groups wrestle to correlate runtime threats from throughout working containers and the Kubernetes management airplane due to the issue with capturing, storing, and processing these two knowledge sources collectively.
Uptycs captures knowledge from the management airplane and the information airplane, bringing these sources collectively in actual time for instant-on detection capabilities.
Developer-friendly registry scanning
Registry scanning is an important a part of devops safety. Deployments have gotten quicker and it’s important that container pictures are “golden” earlier than they hit run time. The burden is shifting additional left, and safety groups want dependable and seamless methods to help devops processes. It’s now not sufficient to detect vulnerabilities. You want methods to prioritize them.
Coordinating remediation efforts throughout devops, operations, and safety groups is a tough process. To assist information these groups, Uptycs supplies essential context by sensible indicators to point not solely what vulnerabilities are current, but additionally easy methods to prioritize remediation efforts. Merely offering a severity rating shouldn’t be sufficient. Groups must know whether or not community ports are open to the web or if the software program in query is definitely working.
Uptycs can scan your container registry for 60,000 Linux CVEs and 7M indicators. Automated scanning incorporates new CVEs as they’re revealed to seamlessly monitor and replace a registry’s safety posture. Supported registries embody JFrog Artifactory, Amazon Elastic Container Registry, Google Container Registry, Azure Container Registry, and Docker Hub.
Uncovering embedded secrets and techniques
Public and embedded secrets and techniques are shortly changing into a typical entry level for attackers, a pattern underscored late in 2022 when attackers compromised Uber by stealing hard-coded credentials contained in PowerShell scripts.
With Uptycs, you may scan pictures for embedded secrets and techniques utilizing Yara guidelines and greater than 100 regex-based alerts, included into your CI/CD pipeline for Jenkins, GitLab, and GitHub Actions. You possibly can help devops staff even additional by failing picture builds from reaching manufacturing when secrets and techniques are found.
NSA hardening checks for Kubernetes deployments
Your Kubernetes management airplane is the central command-and-control API server in your container deployments. As such, it requires most safety, with pictures in runtime needing additional safety and hardening too. That’s why the NSA and CISA have launched in depth steering round hardening K8s and container runtime deployments by revealed configurations for pod safety and community segmentation.
These revealed requirements mitigate the risk from three core attacker targets: DDoS to convey down working containers, hijacking containers to show them into cryptominers, and knowledge exfiltration.
Uptycs has translated these NSA pointers guidelines into compliance guidelines. So, for instance, making use of a “Deny containers with HostPID entry” rule set turns into as straightforward as enabling the rule set. Then, after a container launches out of your Kubernetes management airplane, your runtime shall be constantly validated in opposition to the record of NSA hardening checks throughout run time to make sure that an attacker hasn’t modified the container to escalate privileges or that containers aren’t drifting from their golden picture.
Ganesh Pai is founder and CEO of Uptycs.
