New Features:
- New RHACS dashboard and widgets
- New default policy for privilege escalation: detects if a deployment is running with a container that has allowPrivilegeEscalation set to true. This policy is enabled by default. The privilege escalation setting is enabled in Kubernetes pods by default.
- New default policy for externally exposed service: detects if a deployment has any service that is externally exposed through any methods. The policy is disabled by default.
- Ability to assign multiple RHACS roles to users and groups: Allows you to assign multiple roles using key-value pairs to a single user or group.
- List of network policies in Deployment tab for violations: A new information section has been added to help resolve a "missing Kubernetes network policy" violation that lists all the Kubernetes network policies applicable to the namespace of the offending deployment.
- Alpine 3.16 support for Scanner
Enhancements:
- Change to roxctl image scan behavior: The default value for the --include-snoozed option of the roxctl image scan command is set to false. If the --include-snoozed option is set to false, the scan does not include snoozed CVEs.
- Diagnostic bundles update: These now include notifiers, auth providers and auth provider groups, access control roles with attached permission set and access scope, and system configuration information. Users with the DebugLogs permission can read listed entities from a generated diagnostic bundle regardless of their respective permissions.
- Align OCP4-CIS scanning benchmarks control numbers: The CIS control number has been added to compliance scan results to enable customers to reference the original control from the CIS benchmark standard.
Notable technical changes:
- eBPF is now the default collection method: Updated the default collection method for Collector to eBPF.
Deprecated features:
- RenamePolicyCategory and DeletePolicyCategory API endpoints
- Permissions: AuthPlugin, AuthProvider, Group, Licenses, Role, User, Indicator, NetworkBaseline, ProcessWhitelist, Risk, APIToken, BackupPlugins, ImageIntegration, Notifier, SignatureIntegration, ImageComponent
