ANDOVER, MA–( EMWNews – April 1, 2008) – Enterasys Networks Inc., the Secure Networks

Company™, announced today a new Distributed Intrusion Prevention System

(IPS) to automatically sense and respond to threats in real-time across

multi-vendor wired and wireless networks. Rather than restricting IPS

visibility and control to a subset of network connections, IPS proactive

protections are extended to every LAN edge access port and all WLAN 802.11

frequencies to detect threats, mitigate or stop any attack and, most

importantly, automatically contain and/or remove the source of the threat

from the network. The solution integrates with switches and intrusion

detection/prevention appliances from multiple vendors to leverage existing

infrastructure investments while automating responses to security

incidents.

“Network security needs to be built-in everywhere, rather than bolted-on

somewhere,” said Mike Fabiaschi, Enterasys President and CEO. “Enterasys

advanced security software delivers fully distributed protection from both

internal and external threats without having to deploy appliances on every

wire. Rather than just telling you that a threat exists — we make it easy

to immediately remove the threat from any multi-vendor network without

impacting performance.”

IT operations can avoid the performance bottleneck and scalability

limitations of traditional in-line IPS appliances by deploying Enterasys

Distributed IPS. Unlike traditional IPS solutions that cannot provide

critical threat identification, location, containment, and removal

capabilities; the Enterasys Distributed IPS solution removes the source of

the attack’s access to the network and reconfigures network devices from

Cisco, Enterasys, Foundry, HP ProCurve, Juniper, Nortel, and other vendors

to prevent future access. Depending on the capabilities of existing

switches, automatic responses can range from throttling inappropriate

traffic and/or blocking individual user/device access (for Enterasys

policy-enabled switches), assigning packets to a quarantine VLAN (for all

RFC 3580 compliant switches) or turning off the port (for any SNMP MIB II

compliant switches).

“Self-securing networks are one step closer to reality with this

cost-effective approach,” said Charlotte Dunlap, Current Analysis Senior

Analyst, Enterprise Security. “As network security evolves from access

control to content control, enterprises need a way to dynamically protect

the network infrastructure from accidental and malicious attacks — without

deploying expensive security appliances everywhere.”

The Enterasys Distributed Intrusion Prevention System is the industry’s

first comprehensive IPS solution to cost-effectively address real-world

operational requirements by:

--  Identifying a vulnerability, threat or security event

--  Mitigating an attack by dropping the attack packet(s)

--  Reporting the details of the attack

--  Locating the exact physical source of the attack

--  Containing the threat by removing the source from the network

    

Enterasys Distributed IPS can also play a key role in post-connect Network

Access Control (NAC) for continuous threat analysis, network behavioural

analysis and deep packet inspection to assist in data leakage protection.

Deploying the Enterasys Distributed Intrusion Prevention System reduces the

exposure of IT resources to internal and external threats due to targeted

business disruptions, opportunistic predators, or accidental malware

infections. When dealing with fast-propagating threats to the enterprise

like malware, time is of the essence. It is imperative to react quickly and

effectively in mitigating a threat to prevent critical business processes

from being impacted, ensuring continuity of operations, and reducing

overall risk to the business.
