• Understanding the context of a system is important in determining how much to spend on defending it and what the value of the thing being defended is
• Establishing trust in the foundation of a system is crucial before building on top of it
• Developing a framework for trust involves asking questions about what is being trusted and why, and what the consequences are if that trust is violated
• The blast radius of an incident should be kept small to minimize the impact of a breach or failure
• The concept of 'zero trust' should be renamed to 'zero implicit trust' to make it explicit that something is being trusted and to encourage proper analysis and risk assessment

• Secrets are essential for applications to function properly, but cannot be stored in Version Control Systems
• Kubernetes Secrets are the representation of secrets in Kubernetes
• By default, Kubernetes Secrets are stored unencrypted in etcd
• The Secret Store CSI Driver provides a more secure solution for managing secrets in Kubernetes
• The Secret Store CSI Driver integrates seamlessly into code and ensures robust security and least privilege access
• Other solutions for managing secrets in Kubernetes include Vault, environment variables, and Mozilla Subs

• Verifying identity and large entities is important in supply chain actions
• Working with the SKET project to build a transparency log and record identities and signatures
• Incorporating additional metadata around supply chains, such as S-BOMs and SPGX, to have more fine-grained controls
• Proposing a new sub-project of Notary to directly store TUF repository metadata in the registry
• Seeing Notary projects as a home for a set of standards around supply chain security

• Image scanning and S-bomb generation tools are sensitive to changes in metadata and the quality of the steps involved in building images, and inconsistent results can cause problems for organizations
• Malicious actors can manipulate the results of these tools, causing downstream effects and potentially compromising security
• To prevent attacks, tool makers should adopt a more adversarial approach and provide a more restrictive mode with detection coverage as the focus
• Users of these tools should check for unusual behavior, validate inputs and processes, and consider their threat model when making policy decisions
• Teams should work together to achieve larger goals and reduce toil

• Rootless containers can solve the issue of containers running as root, but there is a limitation in building OCI containers rootless
• The controllers in Kubeflow pipelines run as cluster admin, which is a security risk
• Namespace sharing can also be a security risk as collaborators gain access to service accounts
• Solutions proposed include reducing the complexity of controllers and using reduced cluster roles
• The presentation highlights the progress made in Kubeflow security, such as authentication and machine-to-machine authentication

• Gatekeeper project is a customizable Kubernetes admission web hook that uses Opa engine to enforce policies and enhance governance in organizations
• Gatekeeper is used to ensure that workloads deployed to Kubernetes clusters are compliant with governance and company policies
• Google Anthos and Microsoft Azure have embedded Gatekeeper in their policy engines
• Gatekeeper simplifies the process of building an admission web hook
• Gatekeeper uses Opa engine to enforce policies and enhance governance
• The presentation also discusses updates to Opa, including new built-in functions and upcoming features such as schema validation and a more user-friendly output for tests

• TUF and I10 are complementary projects that can be used together to secure the software supply chain
• TUF allows for the use of metadata to associate internal metadata with the artifact being distributed from the repository
• I10 provides enhanced capabilities for layouts that allow for the verification of the software supply chain execution
• Witness is a community-driven open source implementation of TUF that focuses on indoor attestations
• Witness has developed tools such as the witness run action and the policy tool to simplify the creation and consumption of attestations

• Continuous behavioral analysis can replace manual policy definitions
• Native policies allow for direct enforcement of security policies within Kubernetes
• Hands-on practices for implementing this approach are covered
• The presentation emphasizes the importance of leveraging innovative approaches to security in Kubernetes clusters

• Using metrics from Prometheus to detect anomalies in network traffic and CPU usage
• Manipulating data from Kubernetes metrics to generate topology diagrams of the cluster
• Using service-level metrics to create network topology diagrams
• These techniques can be useful for detecting and investigating security breaches
