Network Intrusion Detection: Evasion, Traffic Normalization, and End-to-End Protocol Semantics
White Paper A fundamental problem for network intrusion detection systems is the ability of a skilled attacker to evade detection by exploiting ambiguities in the traffic stream as seen by the monitor. This paper discusses the viability of addressing this... [21 May 2008]
Network Intrusion Detection: Evasion, Traffic Normalization, and End-to-End Protocol Semantics
White Paper A fundamental problem for network intrusion detection systems is the ability of a skilled attacker to evade detection by exploiting ambiguities in the traffic stream as seen by the monitor. We discuss the viability of addressing this problem by... [24 Feb 2004]
Traffic Analysis: From Stateful Firewall to Network Intrusion Detection System
White Paper This paper investigates traffic analysis techniques need in stateful firewall and Network Intrusion Detection System (NIDS). This calls for the necessity of analyzing the traffic (packets) on the network. [24 Apr 2008]
A Parallel Architecture for Stateful Intrusion Detection in High Traffic Networks
White Paper These issues are critical especially for Network Intrusion Detection Systems (NIDS) that need to trace and reassemble every connection, and to examine every packet flowing on the monitored link(s), to guarantee high security levels. [21 May 2008]
Using sFlow and InMon Traffic Server for Intrusion Detection and Other Security Applications
White Paper With organizations becoming more and more dependent on network infrastructure for business critical applications, unauthorized access to networks can have a significant impact on the ability of a business to function. [10 Jul 2008]
An Intrusion Detection System for Security Protocol Traffic
White Paper The Internet has emerged as a medium for wide-scale electronic communication involving financial transactions and other sensitive information. Encrypted exchanges between principals are widely used to ensure data security. [30 Jun 2008]
Cisco Security Advisory: Cisco Secure Intrusion Detection System Signature Obfuscation Vulnerability
White Paper Intrusion Detection Systems inspect network traffic for suspect or malicious packet formats, data payloads and traffic patterns. Intrusion detection systems typically implement obfuscation defense - ensuring that suspect packets cannot easily be... [10 Apr 2008]
A Distributed Intrusion Detection Prototype Using Security Agents
White Paper The design and implementation of the Distributed Intrusion Detection prototype relies on Security Agents which monitor network traffic and report intrusion alerts to a central management node. Intrusion Detection is the problem of identifying... [01 Jul 2008]
Generic Intrusion Detection Evaluation Guide
White Paper Network-based intrusion detection software monitors and evaluates network traffic for two types of problems - 1) Attacks, either from outside or inside the network, and 2) network misuse as it is defined by your organization’s security policy. [24 Feb 2004]
IDGraphs: Intrusion Detection and Analysis Using Histographs
White Paper For a statistical Intrusion Detection System (IDS), it is crucial to detect at the flow-level for accurate detection and mitigation. IDGraphs is an interactive visualization system for intrusion detection that addresses these challenges. [03 Jul 2008]
Detecting Abnormal Network Activities With Netflow
White Paper Some organizations also use Intrusion Detection Systems (IDS) on border routers to analyze incoming traffic for patterns that indicate specific problems. But firewall or intrusion detection system is used primarily on borders with the Internet... [05 Oct 2006]
Target-Based TCP Stream Reassembly
White Paper The authors revealed that intrusion detection systems cannot be effective and accurate because they do not necessarily process, or perhaps, even observe network traffic exactly as the destination host that receives the message does. [26 Dec 2007]
On the Design and Use of Internet Sinks for Network Abuse Monitoring
White Paper In contrast to traditional intrusion detection systems or firewalls, iSink includes an active component that generates response packets to incoming traffic. Monitoring unused or dark IP addresses offers opportunities to significantly improve and... [08 Jan 2008]
Globix offers protection against brute force net attacks
News Hosting services company Globix has turned to Top Layer Networks to offer intrusion detection to customers whose online services are vulnerable to attacks We view intrusion detection systems as smart firewalls, so for the past nine months we've... [21 Jul 2004]
A Framework for an Adaptive Intrusion Detection System With Data Mining
White Paper The goal of a network-based Intrusion Detection System (IDS) is to identify patterns of known intrusions (misuse detection) or to differentiate anomalous network activity from normal network traffic (anomaly detection). [01 Jul 2008]
