September 30, 2020 | Rule Changes Write below root: Similar to the rules that rely on a process name for exceptions, events will not be triggered if the process name is missing. For example, "". Delete or rename shell history. Ignore docker programs that would prevent modifying shell history, when the path is expressed within the container filesystem (/.bash_history) and host filesystem (/var/lib/docker/overlay/.../.bash_history). All Rules: Changes to the tags to add NIST 800-53 and SOC2 tags:

September 23, 2020 | Rule Changes Launch Sensitive Mount Container: Change image matching to correctly identify Sysdig images as compared to names starting with "sysdig..." Detect shell history deletion: Ignore paths below /var/lib/docker. For example, the container filesystem overlay images that are removed when a container is removed. The Packet socket created in container rule is now enabled by default.

September 10, 2020 | Rule Changes All Rules: Add user.loginuid as an output field. This uid is generally unchanging across sudo/su commands, and can more reliably identify users. Launch Privileged Container: Add additional images that can run with privileged=true. Launch Sensitive Mount Container: Fix a typo that allows docker.io/sysdig/agent-slim to perform sensitive mounts. Read sensitive file untrusted: Allow linux-bench to read sensitive files containing user information. Update Package Repository: Restrict checks to files below known package management directories. Write below etc: Add exceptions related to calico within containers. Write below root: Allow mysqlsh write to /root/.mysqlsh . Read sensitive file untrusted: Allow google_oslogin_{control} read sensitive files. Change thread namespace: Trigger only when the process name is known. Create HostNetwork Pod: Allow several images related to GKE + default metrics/routing services run with hostnetwork=true. Disallowed Kubernetes User: Add several known Kubernetes users to allowed list. Pod Created in Kube Namespace: Allow several images related to GKE + default metrics/routing services run in kube-system/kube-public namespaces. System ClusterRole Modified/Deleted: Allow modifications to the role system:managed-certificate-controller.

April 9, 2020 | Rule Changes Default Policy Changes Remove the default Policy Launch Privileged Container. The rule it used is also in the existing default policy Inadvised Container Activity, so there's no change in rule coverage. New default policies Payment Card Industry Data Security Standard (PCI DSS) and NIST 800-190 Application Container Security Guide, which are disabled by default, contain rules specifically related to PCI and NIST standards.
