Managing network security gets harder every day as the number and types of threats multiply. Security is also a double-edged sword, and an incorrectly implemented or mismanaged security policy can prevent network commerce and stand in the way of the mission of the enterprise.

But if an intruder penetrates the network perimeter, your company’s data and reputation could be forever compromised. To ramp up levels of security, network admins are turning to intrusion detection solutions. These packages constantly monitor network traffic, looking for evidence that points to malicious intent and blocking threats before they cross the network boundary. Enterasys Networks has rolled out Dragon Network Defense, an addition to its existing Dragon Security Suite and Secure Networks product line.
