Network Security Platforms Deep Incite

 Unified Threat Management and Next­Generation Network Security Platforms Executive Summary Sponsored by: Network Security Platforms Executive Summary 2 Overview
The majority of IT organizations have historically relied on a patchwork of
point products to construct the technology pillar of their information security
architectures. For practically every new class of threat, the routine has been to
purchase, deploy, and maintain yet another agent, appliance, or, perhaps
managed service. But the pressure has been steadily mounting, and now the
pot is boiling over.
For a variety of reasons, today’s organizations must account for: (a) more
points of entry into their networks, (b) a greater number and variety of
resources that require protection, and (c) a substantially faster, more elusive,
and more diverse population of threats poised to exploit any exposed
weaknesses. And, of course, they must do so without breaking the bank.
In this regard, Unified Threat Management (UTM) and Next-Generation
Network Security Platforms (NNSPs) can provide a measure of relief. The
reductions in cost and complexity, and improvements in security effectiveness
achieved by having multiple countermeasures available in a single device are
clearly advantageous. Furthermore, steady improvements in the areas of
manageability and performance are expanding the number of use cases for
which these solutions are suitable.
Security Incite believes that organizations of all types and sizes – not just
SMBs – should be evaluating the UTM devices and NNSPs for use in their
computing environments. When doing so, however, it is important to keep
two points in mind. First, all products in this category are not created equal.
There will inevitably be a lot of variation among available solutions,
especially when it comes to price/performance, security stopping power, and
the degree of true “unification” that has been achieved. And the second point
is that even though a lot of progress has been made, this does not mean UTM
will be the right approach for all scenarios or, for that matter, all
End User Requirements Prevailing conditions relative to the threat, business, and technology
landscapes have changed the nature and scope of information security
requirements. For instance, establishing comprehensive protection for
computing systems and associated information assets is not just a good
business practice; in many cases it is now mandated by any number of
regulations and corporate policies. In addition, what constitutes
“comprehensive” has expanded substantially in recent years. The net result it
Full report available at:‐NetworkSecurityPlatforms © 2008 Security Incite. All rights reserved. Network Security Platforms 3 that security practitioners need to consider three distinct dimensions –
functional, logical, and physical – when architecting their organization’s
Functional requirements
Today’s hackers are less interested in gaining notoriety than they are in
making money. Consequently, for the past several years there has been a
noticeable spike in threat development and greater focus on successfully
evading commonly deployed countermeasures in order to “obtain” valuable
information (like intellectual property and credit card data). New threats are
being generated more rapidly than ever before, diminishing the effectiveness
of conventional reactive countermeasures such as patching and antivirus
software. And the concerns of the past (e.g., file-level viruses, worms, and
denial-of-service attacks) are now being over-shadowed by an array of newer
attacks, such as spyware, spear phishing, keylogging Trojans, rootkits, and
even targeted attacks.
In response, organizations need to establish defenses that provide greater
functional coverage. Positive-model countermeasures that operate on the basis
of specifying allowed traffic and then blocking everything else (e.g., firewalls)
should be “blended” with negative-model controls that subsequently filter the
allowed traffic for any malicious, known attack elements (e.g., intrusion
prevention). Purely preventive mechanisms used to block unwanted traffic
should be complemented by capabilities geared more toward monitoring for
suspicious activity or recovering from attacks that have already occurred. And
type-specific countermeasures should also be included to address threats that
warrant focused attention, such as spyware and rootkits, due to the need for
specialized inspection techniques.
In terms of network-based security solutions, this translates into having to
implement the following types of countermeasures and capabilities:
Core functionality includes network firewall, IPSec VPN, intrusion
detection/prevention, and network antivirus;
Common functionality includes URL filtering, anti-spyware/malware,
application control (e.g., for instant messaging, Skype, BitTorrent
clients, etc.), SSL VPN, and host integrity checking; and,
Extended functionality includes web application firewall, applicationspecific security (e.g., for VoIP), and data leak prevention.
Logical requirements
Another consequence of the shift in hacker motivation to fraud is threats are
steadily migrating up the computing stack. By focusing on system and
application-layer weaknesses hackers can enable their creations to slip
Full report available at:‐NetworkSecurityPlatforms © 2008 Security Incite. All rights reserved. Network Security Platforms 4 through traditional network-centric countermeasures deployed by most
organizations. Of course, it doesn’t help matters that web applications, in
particular, have proven to be notoriously vulnerable and are widely
recognized as promising “front doors” to all sorts of lucrative data.
In any event, the implication is that establishing comprehensive defenses
depends on implementing countermeasures that provide complete logical
coverage. Threats and vulnerabilities need to be addressed at all layers of the
computing stack. In other words, protection is necessary not only for network
and system-level components but also for:
Application services
(e.g., layer-7 protocols
such as HTTP, FTP, and
Utility applications
(e.g., web, directory,
and database servers);
Business applications
(e.g., Word, Outlook,
and SAP); and
Individual data
elements (e.g., social
security numbers
(SSNs), personal
healthcare information).
Physical requirements
PERVASIVE PERIMETERIZATION “De‐perimeterization” has garnered a lot of attention. But is it really a practical approach to pursue? Pervasive perimeterization, just like de‐
perimeterization, acknowledges that conventional perimeter defenses have been eroded. But it does not call for their dissolution. Nor does it rely on futures such as “inherently secure communications” and “data‐level authentication”. Instead, by deploying countermeasures to establish additional “perimeters” throughout the internal network and on individual endpoints as well, organizations effectively evolve their defenses to more fully embrace the practice of defense‐in‐depth. The third dimension deals with
the glaringly obvious fact that a
primarily on defending an
boundaries is no longer sufficient. Threats now have more points of entry into
enterprise networks due to increasing user mobility, the proliferation of
remote offices, and greater degrees of interaction and collaborative business
processes between businesses and their customers and partners. There has also
been recognition, particularly in the form of industry regulations that the risk
of internal threats is far from negligible. The result is the need for
organizations to establish comprehensive physical coverage by pursuing a
strategy of “pervasive perimeterization.” In other words, appropriate
countermeasures should be deployed not only at primary connections to the
Internet, but ideally at multiple points within the “internal” network as well.

Branch office Internet and WAN connections;
The interface to high-profile segments and sensitive enclaves;
The core of the enterprise network;
Within the data center (e.g., front-ending virtualized desktop server
Consumer-to-business connections;
Business-to-business connections;
Employee-to-business connections (e.g., for remote access); and
Employee-to-internet connections (e.g., web and email security
Solution Architectures When evaluating solutions to address the tall order of establishing
comprehensive functional, logical, and physical coverage for network-based
security, there are a number of alternatives that security practitioners can
consider. A brief treatment of the available options is as follows:
Do nothing – Achieving perfect security is impossible. At the same
time, however, failing to implement countermeasures to prevent and/or
react faster to widely recognized threats borders on negligence. It’s
safe to say that no business wants to be the next TJX or Hannaford
Brothers; so even though doing nothing is an option, it’s clearly not a
good one.
Use point products – Maintaining the status quo and relying solely on
a vast collection of point products causes the solution to directly
mirror the diversity and complexity of the problem. This is simply not
a sustainable approach. It is inefficient, expensive, and ultimately
ineffective. The cost to operate an ever-expanding set of tools steadily
rises even as threats continue to penetrate through the inevitable gaps
that characterize this type of patchwork defense. That said point
products typically afford the greatest levels of performance, functional
specialization, and configurability. Quite often they are also the only
option for dealing with new classes of threats when they first emerge.
Full report available at:‐NetworkSecurityPlatforms © 2008 Security Incite. All rights reserved. Network Security Platforms 3.
Implement conventional UTM – Early generation UTM devices are
familiar to most organizations. These products typically started “life”
as firewalls and subsequently accumulated a wide range of additional
capabilities (VPN, IPS, etc.). Although they provide a decent measure
of consolidation – thereby reducing infrastructure complexity and
costs – they often have limitations in terms of the robustness of the
included countermeasures, the degree of integration and
configurability, and/or overall performance and scalability. As such,
the products in this category have had limited traction outside of
SMBs and the branch office locations for larger enterprises.
Deploy enterprise-class UTM – The latest UTM products differ from
their predecessors in that they have new architectures. In particular, the
underlying hardware and software is being designed specifically to
meet the needs for UTM. Simple things are now accounted for, such as
having disk space to support quarantining of spam and viruses. More
importantly the hardware has been beefed up considerably, and first
stabs are being made to optimize associated software, including the
interactions between different countermeasures. As former limitations
are incrementally addressed, this opens the door for UTM devices to
be used in a much wider variety of large company scenarios.
Use Next-Generation Network Security Platforms (NNSPs) – Not
satisfied with just addressing technical limitations, the purveyors of
this relatively recent entry on the scene have also instituted a name
change to help escape the connotation between “UTM” and low
volume, low criticality use cases. The chief difference relative to
enterprise-class UTM solutions lies in the approach that is being taken,
of which there are two main varieties:
6 o Emphasis on “less being more” refers to those solutions that
combine a smaller set of operationally related countermeasures
(e.g., firewall, VPN, and IPS for an access control gateway) in
order to provide greater performance and/or controls that are
more robust. In general, the tighter focus also affords the
opportunity for greater degrees of integration, software
optimization, and configurability.
o Emphasis on “the platform” refers to those solutions that are
focused predominately on the underlying plumbing needed to
make things go. Hardware and a collection of system-level
capabilities – such as native load balancing and failover,
internal switching, and a virtualization subsystem – are
provided to support a wide variety of countermeasures
(typically sourced from third parties) that can be arranged
practically any way the customer wants. The goal is to deliver
levels of performance, scalability, adaptability, resilience, and
Full report available at:‐NetworkSecurityPlatforms © 2008 Security Incite. All rights reserved. Network Security Platforms 7 choice that exceed those possible with conventional fixedformat UTM products.
Clearly there are some valid differences between these product categories, but
it is important to realize that many of the distinctions are vendor-driven and
the lines continue to blur. For instance, true, single-function point products are
actually quite rare commodities in today’s network security market. Just about
every firewall available today includes VPN capabilities, and most incorporate
at least rudimentary intrusion prevention. It is also increasingly common for
the underlying hardware/platform to be “purpose-built”, “architected
specifically for UTM”, or otherwise “specialized” in some manner.
At the end of the day, this means enterprises may find that more than one type
of solution is capable of meeting their needs. Still, if a best-fit approach is
pursued, then the outcome will most likely be a combination of most, if not
all, of the options listed above. This is particularly true for larger shops where
there are more total scenarios to account for and the differences between them
are typically more substantial. Again, the key is for each organization to focus
on their specific situation and come up with the mix that best fits their cultural
mindset, at the same time that it achieves a balance between security
effectiveness, operational efficiency, and total cost of ownership.
Value Propositions For architects, engineers, and administrators in the trenches the appeal of
UTM devices and NNSPs is fairly obvious. Bigger pieces of the functional
and logical security puzzle can be achieved with fewer physical devices.
However, convincing senior executives controlling the budget that this
represents a worthwhile investment is a completely different matter. So here
are a few aspects of the UTM/NNSP concept that support the core objectives
of every member of the senior management team, i.e., making more money or
spending less.
Reduce infrastructure complexity – Taking a pure, point product
approach to information security inevitably entails many devices. And
not just the ones that run the requisite security functions. Additional
infrastructure is needed to link them all together, such as switches,
routers, and load balancers. In fact, herein lies one of the fallacies with
regard to the scalability of point products. Although, each individual
unit may support greater throughput, if multiple units are still needed
for each type of countermeasure, then the resulting series of
“sandwiches” (of load balancers, switches, and security devices) can
get insanely complex – not to mention costly. Typically, UTM also
affords the tangential benefit of needing to work with fewer vendors,
as well as being able to gain some associated economies of scale when
Full report available at:‐NetworkSecurityPlatforms © 2008 Security Incite. All rights reserved. Network Security Platforms 8 it comes to purchasing products.
Simplify operations – In addition to having fewer boxes to maintain,
initial installation, integration, and ongoing configuration and
operation of the security devices themselves is simpler and more
efficient. This holds true and varies in direct proportion to the extent
that the solution eliminates the need to install and harden operating
system and associated security software, and to the extent that the
vendor has integrated the different functions and their management.
Enhance security effectiveness – In general, employing these solutions
enables organizations to bring more security capabilities into play in
more locations than would otherwise be the case. Additional gains are
also possible depending on the nature and extent to which the
individual countermeasures are integrated. In any event, the result
should be a stronger defensive posture and, therefore, fewer incidents.
This means less downtime for crucial business systems, less exposure
of sensitive data, and fewer resources needed to put things back in
order, including the company’s reputation.
Foster greater flexibility – Deploying UTM devices and NNSPs
provides a measure of adaptability and allows customers to use
capabilities at their own pace. Some features may go unused upon
deployment, but then can be turned on in the event the need arises
(e.g., if a main AV gateway fails, or a certain business unit decides it
needs its very own WLAN) – all without having to purchase, deploy,
and maintain an entirely new product.
Solidify compliance posture – A good deal of achieving compliance
with applicable security and privacy regulations comes down to being
able to demonstrate the presence of a “reasonable and appropriate” set
of defenses. In this regard, multi-function appliances can help cover a
lot of ground or, in other words, check boxes on auditor’s inspection
Selection Criteria The potential benefits for UTM solutions can be considerable. Yet, users are
cautioned to pay careful attention during the procurement process because
there is still a lot of feature and function variability. The market has not
commoditized to the point that all the solutions are the same. Thus,
organizations have a clear opportunity to find a best-fit alternative. But this
also means there are still some lemons out there as well.
Full report available at:‐NetworkSecurityPlatforms © 2008 Security Incite. All rights reserved. Network Security Platforms 9 Accordingly, Security Incite recommends organizations use the following
criteria to guide their evaluation of candidate solutions.
Security functionality. Does the product include a reasonable set of
security services, i.e., ones you need today and ones that may be
needed in the future, but not a lot that are superfluous? If not best in
class, are the countermeasures at least “good enough”, particularly in
terms of detection/prevention strength, coverage (e.g., for protocols,
applications, and technologies), and feature set? Do the individual
components work together to provide a greater level of aggregate
Performance. Does the product use a general-purpose operating
system and ordinary server hardware, or is the system/hardware
“specialized” for performance purposes (e.g., with dedicated
processors for cryptographic and/or content processing operations, or
custom ASICs)? To what extent has the software been optimized for
performance (e.g., are packets “cracked” multiple times, are inspection
techniques applied selectively or to every packet/session regardless of
its type)? Are published performance ratings for real-world conditions
(i.e., with mixed traffic types and high availability, NAT, dynamic
routing, and logging all turned on)? Do independent test results
support vendor throughput and latency claims?
Reliability. Does the product portfolio include one or more models that
support features such as: a dedicated management port; native failover
and clustering; an out-of-band management interface and separate
control and data planes so that the system is manageable even when
under duress; redundant components, such as fans, power supplies, and
disks; and a configurable option for failing open or closed?
Management. Does the associated management application include
the ability to remotely manage multiple devices at once, as well as
other scalability features such as hierarchical policies, delegated
administration, object re-use, and flexible grouping? Is more than one
management application needed to account for different
countermeasures or device models? Is there a high degree of
intuitiveness and ease of use pervasive across the full set of lifecycle
troubleshooting, and reporting)? Is there support for granular, rolebased administration to maintain separation of duties? Are the
configuration controls sufficiently granular and are there virtual
systems capabilities to support complex deployment scenarios?

Flexibility and Compatibility. Will the devices be able to fit
seamlessly into the organization’s computing environment based on
support for various networking and security capabilities, such as:
ports/interfaces, routing protocols, VLANs, QoS, directories, and
authentication mechanisms? Will the solution be able to adapt to
changing conditions, both in the near term (e.g., via frequent, dynamic
content updates) as well as over the long haul (e.g., based on having a
modular/extensible design)?
Integration and Unification. To what extent have the included
countermeasures been combined to maximize processing efficiency?
Are there sensible internal handoffs between countermeasures to
enhance the ability to detect and respond to threats?
management functions such as logging and reporting been
consolidated, and has rule configuration been sensibly integrated to
simplify policy instantiation and to minimize the potential for errors
and omissions?
10 Summary The scope of the security problem continues to grow, and fighting the battle
with point products alone is clearly a losing proposition. Ultimately, IT
organizations must find more effective and efficient ways to establish
defenses that provide comprehensive functional, logical, and physical
Security Incite believes UTM solutions are poised to be a big part of the
answer and, therefore, deserve close consideration. Significant strides have
been made to deliver greater performance, more robust security capabilities,
and better manageability – in part by offering a spectrum of different
solutions, including newer, enterprise-class products and Next-Generation
Network Security Platforms. This does not mean these products are
appropriate for every enterprise use case. But it does mean that the number of
roles they can adequately fill has grown considerably; and this is a trend that
enterprises can expect to continue.
