whitepaper 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.
[22 May 2008]
whitepaper 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...
[22 May 2008]
whitepaper Network intrusion detection systems have become one of several invaluable tools to safeguard critical infrastructure and information. Publicly available Network Intrusion Detection Systems (NIDS) such as Snort and Bro as well as a large number of...
[22 May 2008]
whitepaper To demonstrate the capability of MACE, the paper provides an analysis of stress tests conducted on a popular firewall and two popular network intrusion detection systems. Malicious traffic from self-propagating worms and denial-of-service attacks...
[22 May 2008]
whitepaper Intrusion Detection Systems are important tools for system administrators to protect their network. The method has been successfully implemented as an extension of the Intrusion Detection System "Snort".
[22 May 2008]
whitepaper This paper describes a system for automated generation of attack signatures for network intrusion detection systems. The system applies pattern-matching techniques and protocol conformance checks on multiple levels in the protocol hierarchy to...
[22 May 2008]
whitepaper Intrusion Detection Systems (IDS) suffer from be being overloaded as network rates increase. Attackers can take advantage of this bottleneck by "Blinding" it with innocuous traffic and try to slip the attack traffic by the system without detection.
[22 May 2008]
whitepaper The webcast outlines how Symantec Endpoint Protection for Windows XP Embedded provides a multilayered security approach that includes an application-centric firewall, application control, intrusion prevention and detection, antivirus and policy...
[18 May 2008]
whitepaper Analogous to traffic normalization for network intrusion detection systems, the proposed RouteNormalizer patches ambiguities and eliminates semantically incorrect routing updates to protect against routing protocol attacks.
[15 May 2008]
whitepaper Web servers require patches and updates to be protected from internal and external attacks, and firewalls and intrusion detection and prevention devices are often needed to prevent attacks on the application.
[15 May 2008]
whitepaper 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]
whitepaper Whenever an intrusion occurs, the security and value of a computer system is compromised. This can be done by sending large amounts of network traffic, exploiting well-known faults in networking services, and by overloading network hosts.
[11 Apr 2008]
whitepaper Voices over IP (VoIP) systems are gaining in popularity as the technology for transmitting voice traffic over IP networks. Along with the anticipated widespread adoption of VoIP systems comes the possibility of security attacks targeted against...
[11 Apr 2008]
whitepaper 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]
whitepaper Measuring and testing performance on Intrusion Prevention Systems requires both an understanding of the characteristics of the network environment targeted in the IPS deployment, as well as an awareness of the challenges in building an effective...
[03 Apr 2008]
whitepaper Especially the employed statistical methodologies allow the usage of History for various applications in network security such as intrusion detection and traceback. The complete architecture relies on standardized protocols such as IPFIX and PSAMP...
[04 Mar 2008]
whitepaper Many of the applications are complex (e.g.reconstruct TCP/IP sessions), query layer-7 data (find streaming media connections), operate over huge volumes of data (Gigabit and higher speed links), and have real-time reporting requirements (e.g.to...
[04 Mar 2008]
whitepaper The methods of data analysis and pattern recognition presented are the basis of a technology study for an automatic intrusion detection system that detects the attack in the reconnaissance stage. Applying complex systems theory for information flow...
[03 Mar 2008]
whitepaper This paper presents a novel approach for improving the performance of a large class of CPU and memory intensive passive network monitoring applications, such as intrusion detection systems, traffic characterization applications, and NetFlow export...
[03 Mar 2008]
whitepaper A common notion is that an Intrusion Prevention System (IPS) is nothing more than an Intrusion Detection System (IDS) deployed in-line with blocking capabilities. Although IPS and IDS both examine traffic looking for attacks, there are critical...
