In this list you will find answers to the most frequently asked
questions about SecureScout NX™.
The list will be
updated according to need.
What is SecureScout NX?
SecureScout NX is a network vulnerability assessment tool that
determines whether networks and firewalls are vulnerable to
attacks, and recommends corrective action for identified
vulnerabilities.
What is unique about SecureScout NX?
Most vulnerability assessment solutions are single point devices
designed to scan individual or multiple remote IP hosts.
SecureScout NX provides a distributed console-remote engine
architecture which allows multi-level, multi-segment scanning of
all subnets behind firewalls and a complete evaluation of the
firewall filtering rules between the scanning agent and the
console. This multi-level, multi-segment scanning enables
assessments of any size networks and is more efficient than other
solutions in the marketplace.
Why would a customer need to run a vulnerability assessment
tool inside the network?
IT systems are getting more complex over time. More applications
and features result in more bugs and risks due to configuration
mistakes. Out-of-the-box configurations are based on sound choices
that ease installation. However, these default choices are often
less secure. Security assessment of all IP connected devices in a
network reduces these business risks.
What is included with SecureScout NX?
SecureScout NX is made up of several modules:
The Vulnerability Database contains Test Cases that are
continually updated.
The Console provides a centralized location for conducting and
managing security assessment and firewall tests of one or more
networks.
The Report Generator produces an integrated HTML or PDF report on
test results and fixes for any number of tested network segments.
The SecureScout NX Engine injects packets on the network to test
for vulnerabilities or security weaknesses.
The SecureScout NX Firewall Scan tests firewalls for policy
compliance in order to prevent illegal traffic.
The SecureScout NX Remote Agent enables distribution of the test
load in an enterprise-wide network.
What is the SecureScout NX Engine?
The Engine is the core technology of SecureScout NX. It plays what
we call 'test cases'; The SecureScout NX version of a hacker
attack script. The Engine is able to inject packets onto the
network, receive answers from remote systems, check if they are
still running, determine whether security policies are
appropriate, and detect vulnerabilities. The efficient SecureScout
NX Engine uses modern programming techniques such as
multi-threading to make the best use of the computing power, and a
dedicated network driver to inject packets at a very high rate on
the network. Test cases are implemented in DLLs. Other solutions
have interpreted scripts that usually prove slower and more CPU
intensive.
What is the Vulnerability Database?
The Vulnerability Database is the collection of all installed test
cases.
A test case includes:
a text description of the vulnerability, and its consequences.
suggestions to solve the issue,
access to additional information such as reference URLs on the
World Wide Web, and
a coded script played by the SecureScout NX Engine, to determine
if a target system is vulnerable.
Test cases are stored in a local ODBC-compliant database. An
embedded MS-SQL engine is supplied with SecureScout NX, and its
installation is completely integrated in the SecureScout NX
installation.
What is the Console?
The Console is the powerful, yet easy-to-use graphical user
interface of SecureScout NX. From the unified centralized Console,
a user can manage all SecureScout NX activities, including
network, firewall, and remote segment security testing via
distributed engines. Sessions can be created that recall all
configuration choices. This process allows the user to run jobs
with identical parameters and compare changes. Session results are
stored in the local database for easy retrieval.
What is the Report Generator?
All job results can be saved in a set of HTML or PDF reports,
easily read through any Web browser.
The reports include:
the Executive Overview, which gives an overview of the prioritized
vulnerabilities
the Administrator View, which provides all the technical details
of test session results
the hosts view, that gives information about the hosts.
What is the Firewall Scan?
The SecureScout NX has mode that test firewalls. In a typical
configuration, the remote agent is located inside the firewall,
while the Console is outside the firewall (e.g., on the Internet
side of the firewall). The Console and the Remote Agent
communicate with a secure encrypted communication channel that
passes transparent through the firewall.
The key points of the firewall session are:
reverse engineer filtering rules,
policy compliance to verify that no illegal traffic can go through
the firewall, and
check the protection offered by the firewall in application
protocols
The SecureScout NX architecture does not make particular
assumptions about the firewall technology and supports any kind of
configuration, including homemade and shrink-wrapped products.
What is the Remote SecureScout NX Engine?
The Remote SecureScout NX Engine allows users to setup additional
testing engines on remote segments, instead of running all test
cases from the Console. These engines act like the conventional
SecureScout NX Engines, only the Console has been suppressed. In
other words, an administrator can control a Remote SecureScout NX
Engine from his/her own SecureScout NX Console, even if the engine
is located far away on a remote segment.
Benefits of this solution are:
All SecureScout NX activities are centralized in a single
location, reducing the burden on scarce security resources.
A single SecureScout NX report or job can include systems from
several segments: this eases follow-up.
The scan of a remote segment has a lower network overhead as test
cases are played locally. Real-time feedback from the remote
engine to the console is buffered to optimize network
transmission.
The remote engine packet injection is not altered by the WAN
performance, or any packet filtering that could take place between
the console and the remote segment.
Sessions with remote engines can be scheduled via regular OS
features,
Updates of remote engines are supported via the SecureScout NX Web
site.
How should an organization evaluate and compare security
assessment offerings?
According to some vendors, the quality of a security assessment
solution is based on its number of test cases, i.e., the number of
vulnerabilities it can detect. This is only partially true.
An organization should also ask the following about the
implemented test cases:
How many are obsolete, testing for outdated versions of systems
and servers?
How many are disguised redundant tests and not network tests?
How many are NT4 or Windows specific (an organization may have
heterogeneous networks to scan)?
Other important questions to ask are:
Is the test case implementation accurate?
How complete is the test analysis?
How frequently are the test cases updated?
With SecureScout NX, the focus is on adding test cases that are
relevant to current configurations. The accuracy of SecureScout NX
is ensured by testing a large number of configurations and adding
new test cases for relevant vulnerabilities as they are
discovered.
What is a SecureScout NX "Network Session"?
In a typical use of SecureScout NX, the Network Session:
Scans a network segment for existing hosts.
Scans for services (TCP, UDP and RPC) and provides an exact
picture of services running on the target system.
Plays test cases, running all (or just a subset selected by the
user) of the test cases supplied with SecureScout NX.
Stores results in the SecureScout NX Database.
Generates reports as required by the user.
What is a SecureScout NX "Firewall Session"?
The Firewall Session:
Discovers active systems on its segments and reports to the
Console.
Determines the filtering rules on the firewall, i.e., which
packets can go through the firewall? - Does it filter by internal
destination (machine / port)? Does it block illegally built
packets? Does it prevent inbound and outbound IP spoofing?
Checks whether internal systems have been seriously affected by
test cases, (e.g., system crash).
In order to initiate a Firewall session, a SecureScout NX remote
agent is installed inside the firewall (e.g., private network,
DMZ.) and the SecureScout NX Console is outside the firewall
(e.g., Internet side).
The Remote Agent and the Console communicate with each other via a
channel that is established across the firewall. In the Firewall
Session, the Console injects test cases against targets inside the
firewall.
Is encryption built into SecureScout NX?
Yes. The Probe or Remote Engine to Console dialog is encrypted
using SSL v3. Traffic sniffing cannot be exploited by an
attacker.
How is SecureScout NX protected?
A unique license key protects SecureScout NX. The license is
issued using:
The MAC address of the system used to host the SecureScout NX
console
the customer company name as well as the individual using the
scanner, and
the IP address range(s) the customer will be scanning
This means that:
a user cannot scan segments outside of the initial segments
supplied, and
a user cannot scan an outside network (e.g., via Internet, try and
test a competitor's network.)
What are the invaluable features of SecureScout NX that are not
available with other network security assessment solutions?
The unique and valuable features of SecureScout NX include the
following:
Faster Assessment: All activities are centrally managed in one
single location enabling faster assessment of medium to large
enterprise-wide networks.
Consolidated Reporting: A single SecureScout NX report can include
results from one or more network segments.
Low Network Overhead: Test cases are played locally and real-time
reports are buffered to optimize network transmission.
Efficient Testing: WAN performance or packet filtering mechanism
never affects a Remote Test Engine's activities.
Easy Scheduling: Sessions with remote engines can be scheduled via
regular OS features.
In-depth Firewall Configuration Testing: includes reverse
engineering filtering rules with active probing on all types of
firewalls.
Automated On-line Updates: Test cases and dynamic report
generation are updated regularly.
The traditional approach for network vulnerability assessment has
reached its limits. Point-in-time and segment-by-segment scanners
are extremely time consuming for security professionals, as they
generate only snapshots and unrelated per segment reports. The
SecureScout NX distributed 3rd generation architecture combines
consoles, remote test engines and proactive probes, and introduces
a real technological breakthrough designed to meet the security
assessment needs of any size organization.
