Identify outliers to find misconfigurations, missing patches, and rogue devices #

Our users tell us that they know the state of their standard-issue workstations pretty well, but are worried about the unknown unknowns. Attackers love these oddball systems: they are rarely well-managed or patched, and they can be easy targets. A signature-based approach is a game of catch-up that will always miss the most peculiar assets. A simple statistical analysis, however, effectively surfaces these types of systems. The dashboard now shows outliers according to specific attributes. Each card displays both the most and least seen values.

Outlier detection goes beyond the home dashboard. Rumble now includes an outlier score in the asset inventory that indicates how unique an asset and its configurations are. Security teams can filter and query by this score to surface assets worth investigating. This score, a number between 0 and 5, indicates how unique the asset is based on a number of different attributes, relative to the site it belongs to.

The asset details view highlights outlier attributes and indicates how often that value occurs.

While outlier scores are available in all editions, Rumble Enterprise users now also have access to two new reports:

  • The Outlier Overview Report - Lists the most anomalous values for all asset attributes that have a significant commonality. From here, security teams can pivot to an inventory view of only those specific assets.

  • The Specific Outlier Report - Generate this report for a specific asset or service attribute. This report includes a list of assets grouped by attribute value.


Trace potential network paths to verify network segmentation #

Network segmentation is a foundational security control that can be easily undermined by network misconfigurations and multi-homed machines. Rumble Enterprise users can now visualize potential network paths between any two assets in an organization using the Asset Route Pathing report.

This report generates a graph of multiple potential paths by analyzing IPv4 and IPv6 traceroute data in combination with subnet analysis of detected multi-homed assets–without requiring access to the hosts or network equipment. This unique methodology identifies surprising and unexpected paths between assets that may not be accounted for by existing security controls or reviews.

With a view of potential paths, security professionals can verify whether a low-trust asset, such as a machine on a wireless guest network, can reach a high-value target, such as a database server within a cardholder data environment (CDE). The new feature highlights potential network segmentation violations and opportunities for an attacker to move laterally from one segment to another.

Rumble Enterprise users can generate the Asset Route Pathing report to view potential network paths.

Streamline SSO user provisioning #

For Rumble Enterprise customers, single sign-on support now includes support for automatic role assignment through custom rules. Rumble administrators can now map users to groups using SSO attributes and custom rules to ease onboarding, removing the need to provision individual users. SSO group mapping centralizes authorization configuration to the customer's directory or identity provider. A user authorized by SSO can login and automatically be assigned correct permissions, all without pre-provisioning of their account. After evaluating all SSO group mapping rules, Rumble grants the user the highest privilege asserted for each organization. Rumble Enterprise users can set up SSO group mappings in the Rumble console.

Cloud connectors now available in Professional Edition #

Over the past year, Rumble has grown in scope to include cloud assets. Based on customer feedback, we have now made AWS and Azure integrations available in the Professional Edition. Pro customers can now connect to their AWS or Azure environment.

Release notes #

The Rumble 2.11 release includes a rollup of all the 2.10.x updates, which includes all of the following features, improvements, and updates.
