Enhancing Workload Security in Kubernetes
#1about 3 minutes
Understanding the Kubernetes securityContext for workloads
The securityContext field in a pod specification allows you to define privilege and access control settings for a pod or container.
#2about 4 minutes
Restricting kernel system calls with seccomp profiles
Seccomp profiles enhance security by allowing you to explicitly define which kernel system calls a containerized workload is permitted to make.
#3about 4 minutes
Hardening file system access with AppArmor profiles
AppArmor provides mandatory access control by defining profiles that restrict application capabilities like file reads, writes, and network access.
#4about 6 minutes
Implementing fine-grained control with SELinux contexts
SELinux uses a labeling system to enforce mandatory access control policies, providing granular control over process and object interactions.
#5about 2 minutes
Automating security with the Security Profiles Operator
The Security Profiles Operator simplifies the management and distribution of seccomp, AppArmor, and SELinux profiles across all nodes in a Kubernetes cluster.
#6about 5 minutes
Demo of blocking an in-memory execution attack
A live demonstration shows how a seccomp profile can block the `memfd_create` system call to prevent a fileless malware execution attack.
#7about 3 minutes
Demo of managing seccomp with the operator
This demo illustrates how the Security Profiles Operator uses a `ProfileBinding` to automatically apply a seccomp profile to workloads based on their image.
#8about 8 minutes
Demo of troubleshooting SELinux permissions
A practical demonstration shows how SELinux denies access by default and how to use audit logs and tools like `audit2allow` to diagnose and create new policies.
#9about 8 minutes
Q&A on AppArmor, fileless attacks, and eBPF
The speakers answer audience questions about applying AppArmor profiles, the nature of fileless malware, discovering system calls, and the role of eBPF.
