Definition

Attestation in the context of cybersecurity refers to the process of verifying and validating the integrity and authenticity of a system or component. It involves generating evidence that a system is in a known good state, often using cryptographic techniques. Attestation can be used to ensure that software has not been tampered with and that it is running in a secure environment, providing assurance to stakeholders about the system’s trustworthiness.

Secure Settings Example

# Example of a secure attestation policy in a Kubernetes environment
apiVersion: security.k8s.io/v1
kind: PodSecurityPolicy
metadata:
  name: secure-attestation-policy
spec:
  allowPrivilegeEscalation: false
  runAsUser:
    rule: MustRunAsNonRoot
  fsGroup:
    rule: MustRunAs
    ranges:
    - min: 1
      max: 65535
  seLinux:
    rule: RunAsAny
  readOnlyRootFilesystem: true

Insecure Settings Example
