Recently, a member of the Falco community privately disclosed a capacity related vulnerability which, under circumstances where a malicious actor has already gained access to your system, could allow the actor to further bypass Falco’s detection of abnormal activity. The final details are still being worked out, but we believe the CVE will be classified as Medium severity according to the CVSS methodology.

We are happy to announce the release of Falco 0.15.0. This release incorporates a number of improvements, as well as bug fixes, and rules updates. This release also includes a mitigation for CVE-2019-8339, and all users are encouraged to update to this release. You can find more details about the features and improvements in the release notes, but below are a few highlights.

Both OPA and Styra support either, so we have no real bias.

Kubernetes isn’t (just) fun and games anymore.

Unfortunately, the old tools for access control like RBAC simply aren’t up to the challenge.

In September 2017, the National Institute of Standards and Technology (NIST) released Special Publication (SP) 800-190, Application Container Security Guide.
