X5 AND X506 UNIFIED SECURITY PLATFORMS

KEY BENEFITS

PROACTIVE NETWORK SECURITY

The 3Com X5 and X506 devices leverage the best-in-class TippingPoint

IPS Threat Suppression Engine currently used to protect thousands of

enterprise-class networks throughout the world.

The IPS continually cleanses the network at layers 2-7, checking both

Internet and intranet traffic, eradicating threats and helping to prevent

bandwidth hijacking and malicious traffic—spyware, worms, viruses,

trojans, phishing attempts, VoIP threats and other harmful activities.

Statistical, protocol and application anomaly protection safeguards the

network against traffic surges, buffer overflows and unknown attacks

and vulnerabilities (zero-day threats).

To provide protection against new and evolving security threats, updated

attack filters are incorporated into Digital Vaccine

Attack Filter Update

Services, provided by TippingPoint, which are automatically distributed

to all subscribing 3Com X5 and X506 devices, providing pre-emptive

protection against new and zero-day vulnerabilities. The Digital Vaccine

service offers this protection and prevention on a weekly (or more

frequent) basis.

Recommended settings for IPS filters enable preconfigured policies

that can automatically and accurately block attacks without any tuning,

significantly reducing the time and resources required to protect and

maintain a healthy network. This ensures that no "good" traffic is

blocked and no "bad"' traffic is permitted, with no security expertise

or fine-tuning of settings required.

ADVANCED VPN CONNECTIONS

While most security implementations do not address security within a

VPN connection, 3Com Unified Security platforms take a uniquely com-

prehensive approach to VPN-based security by providing the ability to

look inside VPN IPSec tunnels for threats. This thorough inspection pre-

vents propagation of exploits and other malware between sites and can

also be used to provide protection from security risks that occur when

laptop users terminate VPN connections while traveling.

Another unique feature is prioritization of bi-directional traffic inside the

VPN tunnel, enabling high-quality secure VoIP services and optimizing

other site-to-site applications. Threats that once gained access via a VPN

tunnel are now eliminated by this unique approach, offering complete

security protection, ensuring that remote VPN clients or branch offices

cannot be used to propagate threats into the LAN.

APPLICATION PRIORITIZATION AND OPTIMIZATION

Using a single X5 or X506 device for application prioritization and

optimization of network traffic, instead of separately managing multiple

switches and routers, reduces complexity and cost while providing

greater flexibility.

To control the amount of bandwidth allotted to applications and deliver

the appropriate quality of service (QoS), 3Com X5 and X506 devices

can throttle down non-critical applications such as FTP, and throttle

up business-critical and latency-sensitive ones such as VoIP. Bandwidth

can be allocated in both inbound and outbound directions for maxi-

mum control.

This policy-based traffic-shaping capability helps prevent network

congestion, giving administrators a powerful tool for making sure that

network services meet user expectations and adhere to the policies set

by network managers.
