Network Situational Awareness via Recursive Network

Network Situational Awareness via Recursive Network Indexing
To properly manage and secure a network, IT managers need authoritative intelligence about their network infrastructure and
cybersecurity posture. Lumeta® IPsonar® provides a point-in-time view of every IP connected device on a network, as well as
inbound and outbound leak path identification.
Lumeta’s network situational awareness platform is
the authoritative source for network infrastructure and
a Lumeta IPsonar provides a clear understanding of entire
cybersecurity* analytics.
routed infrastructure and confirmation that all assets are under
security management.
Lumeta IPsonar provides comprehensive visibility into the
entire routed infrastructure of a network via recursive
network indexing – performing an active probe and mapping
every IP asset, host, node and connection on the network.
The data is then analyzed to understand policy violations and
security vulnerabilities.
How It Works
Through recursive network indexing, IPsonar identifies the
network perimeter, network topology and devices that
encompass a company’s infrastructure. It utilizes the following
a Network protocols (learning network information via
a Port responses (determining the services running in the
a Network packets (understanding the connectivity of a
network via sending lightweight, standard, properly formed
packets throughout the network)
aNetwork path tracing (reaching for devices within the
network via tracing data paths)
What is recursive network indexing? If, for example, IPsonar
finds a new router, one that wasn’t previously known
to the established scan, it will then drill into that new
network device to assess what it is attached to, pull route
tables, etc.
IPsonar provides a point-in-time view of a network, often
used in compliance audit situations. It is also often used
to provide a network ‘baseline’ for M&A activities or in
the case of a new IT executive taking over the security and
management functions of a network.

IPsonar Intelligence
Recursive network indexing and the various IPsonar scans provide intelligence regarding network segmentation and network
architecture: What network enclaves are able to reach others? What are the ‘unknowns’ in the network? What does the network
really look like? What devices are attached to the network and how? Does this violate policy?
Network Segmentation Analytics – advanced intelligence

needed to verify network segmentation and understand the
network architecture relative to an organization’s policy

network, and how)

IPsonar Scan Types
Lumeta IPsonar actively scans the network to collect all data related to Network, Host, Service, Leak Path, Layer 2, and Perimeter.
IPsonar also uses Device Profiling techniques to identify the type, vendor, model, operating system, and version of devices on the
network. Users can accurately visualize what is on the network, drill down to analyze potential areas of risk, and identify appropriate
corrective actions.
Network Discovery – Network Discovery gathers information
Layer 2 Discovery – Layer 2 Discovery finds endpoints, SNMP-
about the network connectivity, leading to the identification
of routing devices (including IPv6-enabled routers) and their
interconnection, the network perimeter and topology, and, in
general, the assets and stealth devices.
accessible switches, hubs, and bridges that are attached to
SNMP-accessible routers.
Host Discovery – Host Discovery identifies all IP addresses
that respond, in one way or another, to network protocols. Host
Discovery is a very important step as it leads to the creation of a
Target List that is further targeted to understand device profile
and details (Service Discovery and Leak Path Discovery).
Service Discovery – Service Discovery scans the ports of
devices to identify vulnerable or infectious ports that may be
open. One of the most common reasons that organizations fail
a compliance audit is the inability to report on and secure open
ports. IPsonar’s Service Discovery scans and reports across all
ports, addressing audit issues. This data can be further analyzed
within the context of IPsonar’s deep and broad network
Leak Path Discovery – Leak Path Discovery verifies that no
Device Profiling – Device Profiling helps determine the
device type, hardware, model, vendor and operating system of
all devices that have been indexed by IPsonar. Device Profiling is
performed via various methodologies:
a Looking for device information via SNMP protocol
a Gathering HTTP/HTTPS responses
a Determining the type of device via the combination of
running services
a Identifying windows devices via CIFS protocol and TCP
pattern matching
Enhanced Perimeter Discovery – Enhanced Perimeter
Discovery helps find Layer 2 attached devices that forward
traffic (just like endpoints, routers or switches) so that they
can be further investigated for forwarding traffic to unknown,
unauthorized or untrusted networks.
Layer 3 devices within the network are leaking to or from the
Internet or other segmented portions of the network. This scan
shows any device that has direct connectivity to the Internet or
a device that has an inbound/outbound connection through the
network perimeter.

IT administrators can receive email alerts on events that meet or exceed a severity tolerance threshold. Alerts are available in
a twice-daily digest form or individually, as they are identified in near real time – empowering users to respond immediately to
incidents and vulnerabilities.
Scalable to the World’s Largest Networks with Multi-tier Enterprise Architecture
Lumeta IPsonar is available in a Cloud or Virtual Machine deployment.
IPsonar does not disrupt operations in order to completely scan a network - no matter how far-flung or numerous the resources are.
IPsonar scales to handle large data sets as easily as it does small data sets. Thus, IPsonar is a true enterprise application, able to work
efficiently in both large and small deployments.
IPsonar’s three-tiered architecture is proven at the world’s most complex networks and has been used to scan the entire Internet:
a Sensors: Accurate, complete network scanning is achieved through the use of network entry points called Sensors. These entry
points are portable, providing flexibility to address even the most fast-changing networks. Sensors provide “scan and send results”
functionality, sending results back to either a Scan Server or a Report Server.
a Scan Servers: These resources are positioned at appropriate points in the network to assure that business applications and even
the lowest-speed network links are unaffected by IPsonar network traffic. Multiple scans can be run simultaneously. Scan Servers
provide “scan and store” functionality.
a Report Servers: A full package, a Report Server provides the functionality to scan the network, analyze the scan data, and display
the report based on the analysis. A single remote Report Server can support multiple Scan Servers.
Communication between IPsonar components is via HTTPS (SSL), so no changes to firewalls or network access control are required.
The user interface supports signed digital certificates.
The number of systems required, and software-licensing costs depend on the size, complexity and segmentation of the network. A
Lumeta consultant will work with you to determine the best architecture and product configuration for your environment.
Plugin Framework for Technology Partner Ecosystem
The intelligence gathered by IPsonar is a necessary foundation for comprehensive network situational awareness. It can be used
in conjunction with an organization’s existing security and network management tools, such as vulnerability management (VM),
security incident and event management (SIEM), intrusion prevention systems (IPS) and network access control (NAC) – enhancing
the value of an organization’s investment in those products. Network, security and compliance products can only be fully effective
when operating with 100% network visibility.
IPsonar contains a framework for embedding plugins with third-party products to facilitate integration. This allows customers to feed
the IPsonar authoritative network intelligence directly into third-party integrated applications. Plugins are available on the Lumeta
