What is KubeArmor?

KubeArmor is hardening its eBPF DNS visibility and supply chain security posture in the v1.7.5 pre-release cycle.

KubeArmor is in active pre-release for v1.7.5, having shipped three release candidates. The rc1 switched the BPF hook for DNS traffic from udp_sendmsg to udp_send_skb — a kernel-level change that captures DNS at the correct interception point for accurate visibility. The rc2 added SLSA Level 3 provenance, isolated container builds, and improved OpenSSF Scorecard compliance to the project's build and release pipeline. Support for Ubuntu 26.04, openEuler 24.03 LTS-SP3, and kernel 6.17 DNS tracking arrived in the 1.7.4-rc3 cycle.

What is Skipper?

Skipper adds Redis as a distributed L2 cache backend amid a high-frequency patch cadence.

Skipper is running in a maintenance-heavy patch cycle, shipping multiple versions per week focused on stability, test infrastructure, and minor performance work. The architectural addition this period is v0.27.92's Redis L2 storage for the cache() filter, which extends caching from node-local to cluster-shared. v0.27.95's parsed filter and predicate caching across RouteGroups is a performance improvement but stays within the current architecture.

KubeArmor is hardening its eBPF DNS visibility and supply chain security posture in the v1.7.5 pre-release cycle.

◆ Current state

KubeArmor is in active pre-release for v1.7.5, having shipped three release candidates. The rc1 switched the BPF hook for DNS traffic from udp_sendmsg to udp_send_skb — a kernel-level change that captures DNS at the correct interception point for accurate visibility. The rc2 added SLSA Level 3 provenance, isolated container builds, and improved OpenSSF Scorecard compliance to the project's build and release pipeline. Support for Ubuntu 26.04, openEuler 24.03 LTS-SP3, and kernel 6.17 DNS tracking arrived in the 1.7.4-rc3 cycle.

◆ Where it's heading

KubeArmor is running two parallel improvement tracks: eBPF policy enforcement quality (BPF hook changes, quota handling via NPE, hostname/TLD matching improvements) and supply chain security compliance (SLSA, Scorecard, pinned dependencies, isolated builds). The latter is increasingly a table-stakes requirement for enterprise Kubernetes security teams auditing their toolchain, not a differentiator. New kernel and OS support signals broadening the deployment surface — particularly for regulated environments with specific OS requirements.

◆ Prediction

v1.7.5 stable will ship shortly given three RCs already published. The eBPF DNS visibility change enables syscall-level DNS auditing for workloads that need it; the SLSA Level 3 provenance will be cited in enterprise security reviews as a prerequisite for adoption.

Skipper adds Redis as a distributed L2 cache backend amid a high-frequency patch cadence.

◆ Current state

Skipper is running in a maintenance-heavy patch cycle, shipping multiple versions per week focused on stability, test infrastructure, and minor performance work. The architectural addition this period is v0.27.92's Redis L2 storage for the cache() filter, which extends caching from node-local to cluster-shared. v0.27.95's parsed filter and predicate caching across RouteGroups is a performance improvement but stays within the current architecture.

◆ Where it's heading

The Redis L2 integration suggests the Skipper team is addressing the multi-replica cache coherence problem that large deployments encounter. If this pattern continues, distributed-state options—persistent rate limiting, distributed circuit breakers using the same Redis client abstraction—are the natural follow-ons. The high patch cadence signals active production deployment rather than feature-driven development.

◆ Prediction

The Redis client abstraction introduced in v0.27.92 will be extended to other stateful filters, particularly rate limiting, given that distributed rate limiting is the most common request for API gateways running at multi-replica scale.
