Network Security
NetDetector – Network Intrusion Forensic System (NIFS)
A NIKSUN White Paper
www.niksun.com
Abstract
Every system connected to the Internet is a potential candidate for a malicious attack. Even the most secure Internet sites, corporations, and government agencies have experienced security violations and network attacks. To deal with those risks, organizations are deploying network infrastructure devices such as firewalls and intrusion detection systems (IDSs) to increase the security of their networks. However, the notion of an impenetrable network is equivalent to the notion of an unsinkable ship, and one need not be reminded of the lessons learned from the Titanic!
Due to the complexity of network attacks and the extent of the damage they cause, organizations are spending considerably more time and resources in recovering from security incidents than in the past. Viruses and worms, such as Nimda and Code Red, have caused major disruptions of service on corporate networks and operation. It has become critical that organizations deploy technologies that help reduce the time and cost of recovering from security incidents.
In order to protect computer networks against unauthorized access, intrusion attempts, and network attacks, best practices dictate deploying multiple layers of devices and technologies to ensure that networks are secure and can recover rapidly from security breaches.
