SummaryHere's what we know. Corporate networks have been fundamentally changed by the growth in networked communications. The Internet, providing information to an exponentially growing number of users and providers, has changed the profile of corporate networks from a closed model to an open vehicle for commerce and communication. At the same time, corporate networks have become mission-critical repositories and mediums for data, assets, and services. Along with that growth have come certain risks that traditional security methods are not fully prepared to address. Firewalls and perimeter protection are no longer enough for a global communications model based on convenient access. Network security personnel can no longer hope that a perimeter fence will secure their network against savvy, patient attackers or threats from the inside.For a corporate network to attain a more assured level of protection, a more active, intelligent technology is necessary. One that actively monitors the network and recognizes the obvious as well as subtle signs of network compromise, whether originating from the outside or inside. One that responds in a time frame that allows for immediate protective action to be taken. One that assists the network security manager at all points in the attack cycle, from initial attempt through the last stages of recovery and case-building. And one that can be implemented and maintained without an excessive burden on either personnel, network structure or network resources. No technology can promise a "silver bullet" solution of iron-clad guarantees and promises of permanent worry-free security. But security methods that recognize the new realities of network communications are more effective than security methods that ignore these realities. Active intrusion detection technology addresses the new realities. When paired with perimeter protection, intrusion detection can provide the level of protection necessary for safeguarding one of the corporation's most valuable mission-critical assets: its own network.
