 ### Enabling Seccomp
 
-Seccomp can improve the security of your workloads by reducing the Linux kernel
-syscall attack surface available inside containers. The seccomp filter mode
-leverages BPF to create an allow or deny list of specific syscalls, named
-profiles. Those seccomp profiles can be enabled on individual workloads,
-[a security tutorial is available](/docs/tutorials/security/seccomp/). In
-addition, the [Kubernetes Security Profiles Operator](https://github.com/kubernetes-sigs/security-profiles-operator)
-is a project to facilitate the management and use of seccomp in clusters.
-
-For historical context, please note that Docker has been using
-[a default seccomp profile](https://docs.docker.com/engine/security/seccomp/)
-to only allow a restricted set of syscalls since 2016 from
-[Docker Engine 1.10](https://www.docker.com/blog/docker-engine-1-10-security/),
-but Kubernetes is still not confining workloads by default. The default seccomp
-profile can be found [in containerd](https://github.com/containerd/containerd/blob/main/contrib/seccomp/seccomp_default.go)
-as well. Fortunately, [Seccomp Default](/blog/2021/08/25/seccomp-default/), a
-new alpha feature to use a default seccomp profile for all workloads can now be
-enabled and tested.
+Seccomp stands for secure computing mode and has been a feature of the Linux kernel since version 2.6.12.
+It can be used to sandbox the privileges of a process, restricting the calls it is able to make
+from userspace into the kernel. Kubernetes lets you automatically apply seccomp profiles loaded onto
+a node to your Pods and containers.

+Since Kubernetes 1.27, you can enable the use of `RuntimeDefault` as the default seccomp profile
