CVE Vulnerability and
Exposure Management

Gaining Useful Visibility into CVEs 
Across Agency Environments

Forward Networks meets the challenges agencies face head-on as they encounter operating system vulnerabilities across distributed, complex hybrid environments. The Forward Enterprise network digital twin offers visibility and attack intent capabilities for the entire agency network estate. The at-a-glance insight available through the platform is critical for agency environments in which the sheer number of vulnerabilities arising each day can quickly outpace IT teams’ ability to respond.

The Cybersecurity and Infrastructure Security Agency (CISA) Binding Operational Directive (BOD) 22-01, Reducing the Significant Risk of Known Exploited Vulnerabilities, is driving progress around remediation of vulnerabilities. The Directive’s CISA-managed catalog of priority known exploited vulnerabilities is a step in the right direction for helping federal civilian agencies address mandates and remediate vulnerabilities within specific timeframes.
"Every day, our adversaries are using known vulnerabilities to target federal agencies. We are using our directive authority to drive cybersecurity efforts toward mitigation of those specific vulnerabilities that we know to be actively used by malicious cyber actors. The Directive lays out clear requirements for federal civilian agencies to take immediate actions to improve their vulnerability management practices.”
Jen Easterly, CISA Director
CISA is helping establish critical baseline priorities; however, the
escalating volume of CVE alerts is still daunting. Increasingly
complex, distributed environments with tens of thousands of
devices from different vendors make it even harder for federal
agencies to keep up with the constant stream of CVE alerts without
becoming overwhelmed. As vulnerabilities increase, assessing and
remediating alerts often fall to the back burner.

While many agencies regularly run network vulnerability scans,
these processes typically run only at night. It can take almost a
week for the information revealed to be transferred to network
engineering teams. With this difficulty in sharing prioritized and
actionable information, even when the team receives the reports,
they are not in actionable form. For protocol-specific alerts,
engineers will still need to manually locate impacted devices
within the network to evaluate risk. Without this level of detail, the
process remains time-consuming and prone to human error. A more
automated, efficient approach is needed to prioritize threats and
achieve CVE compliance both on-premises and in the cloud.

Know What, Where, and “How
Bad?” – CVE Alerts at a Glance

There is a better way for agencies to manage CVE alerts to protect
their security posture and reduce the burden on their IT staff. The
OS vulnerability mitigation functionality within Forward Enterprise
helps agencies prioritize and remediate CVEs for compliance with
CISA BOD 22-01.

Forward Enterprise’s network digital twin capability helps
agencies respond to the growth of hybrid work and the need
to secure collaboration and digital services within constantly
evolving network boundaries. These complexities typically block
understanding of network connectivity and obscure insight into
whether security policies are working and which vulnerabilities pose
the most significant risk.

Security and network engineers can manage and prioritize CVE
alerts easily and confidently with Forward Networks. Visibility into
on-premises, hybrid-cloud, private cloud, public cloud, and multicloud
gives agency IT teams a 360-degree view of networks across
physical and virtual environments. Teams also get a single pane of
glass for end-to-end in-depth connectivity analysis and policy and
security verification.

The operating systems (OS) vulnerability mitigation feature collects
information from the NIST CVE database and automatically
analyzes it against the device and configuration data collected by
the network digital twin for an instant security data call for CVE
remediation. In one dashboard, security operations teams can see
all the key details about the latest CVE alerts — from the severity
level of the alert to how many and which devices in an agency
network are impacted – as well as what sources or subnets can
reach the device to attack the vulnerability.

The example dashboard below shows how the OS vulnerability
mitigation functionality in the Forward Enterprise platform provides
pertinent details about CVE alerts that apply to an agency’s specific
network(s) at a glance. This information includes:
• Severity level of the alerts from critical to not applicable
• Description of each alert
• Vendors impacted by the alert
• OS impacted by the alert
• Which versions of the software are impacted
• How many devices in the network are impacted
The Forward Enterprise platform helps IT teams gain new
efficiencies for vigilant CVE monitoring, making it easier to stay
on top of recent vulnerabilities targeting remote workers and
cloud-based communications software. With access to up-todate,
actionable vulnerability insights automatically curated within
the platform, agency security and network teams can act fast to
prioritize and fix severe vulnerabilities. This capability is especially
important for agencies whose mission means handling sensitive
information where any risk – no matter how small – is too much

This interface lets security and network teams click on “Details” to
view the full configuration and state information for all impacted
devices. Using the Network Query Engine within Forward Enterprise,
engineers can run a query to instantly locate devices running
protocol-specific alerts and immediately determine their risk and
begin remediating it.

API Integration with ServiceNow

The ability to automate the monitoring of new NIST CVE alerts with
detailed information for fast prioritization and remediation makes
it easier for security and network teams to close those gaps before
bad actors exploit them. Automated monitoring can help maintain
compliance without overwhelming stretched staff.

Forward Networks’ API integration with ServiceNow generates
tickets that automate the entire process of addressing OS
vulnerabilities in response to CVE alerts, further reducing the
burden on IT teams. It takes only seconds to enable and configure
this integration. Engineers can automatically share relevant details
about network state, configuration, and behavior with everyone
working to resolve a security or compliance issue. This information
updates within both platforms, creating a detailed and current
single source of truth.

Case Study

Before Christmas 2020, Cisco sent out a field notice that
announced a major issue with many of its network devices. Due to
a bug with expiring self-signed certificates on Cisco devices, many
services and capabilities relying on those certificates would no
longer function.

This was a critical announcement, as the services impacted
included SIP connections, encrypted signaling, gateway calls
using MGCP or H.323 signaling, API calls, RESTCONF, HTTPS
sessions, SSL VPN sessions, IPSec connections, and much more.
Essentially, the chief functions of the network, including basic
internet browsing, would be significantly affected. Identifying all the
affected devices could easily represent weeks of work for impacted

Forward Networks’ users received an automatic update about
this field notice. They turned to the Network Query Engine (NQE)
from Forward Networks to create a custom query to identify the
impacted Cisco devices and report them to the network security
team within hours.

Analyze Network Vulnerabilities
with Mathematical Certainty

Forward Networks’ mathematical model creates a complete and
always current digital twin of your physical, virtual, and multicloud
network estate, including config and state information for all
network elements and your hybrid or multi-cloud environment. The
digital twin provides a comprehensive view of all network behavior,
with visibility into every possible path a packet can take. It brings
mathematical certainty to network security validations by enabling
security operations teams to:

VISUALIZE network layer 2 – 4 topology and all possible traffic
paths within a single pane of glass including on-premises, Cloud
(AWS, GCP, and Microsoft Azure), and virtualized environments.
Then, drill down to specific devices and traffic flows, including
configuration and state data. View the global network in a single
view or drill down to a single device.

SEARCH the entire estate as simply as a database. Our browser-like
search feature performs the industry’s most in-depth, end-to-end
path analyses across the network for both on-premises and cloud
infrastructure. This also enables you to locate devices and access
detailed information on their location, configuration, and state in

VERIFY that the security policies are extended to the cloud
using purpose-built (custom) intent checks. Forward Enterprise
offers the most advanced network segmentation tool available
with support for multi-vendor on-prem, hybrid-cloud and multicloud
environments. Continuously audit the network and receive
actionable alerts for non-compliance with your security policies.
Know that applications are compliant before provisioning them.

COMPARE network changes over time to understand their impact
on the network and prevent incidents from reoccurring. The network
collector frequently scans the network, taking and saving network
configurations, topology, and device state snapshots. These
“snapshots” become a searchable, historical record of network
behavior and compliance at any point in time. And the behavior
diffs feature makes it easy to quickly find and compare snapshots
to identify changes that may violate your security policy.
