Undermining an Anomaly-Based Intrusion Detection System Using Common Exploits
White Paper To date, however, there appears to be no study which has identified a systematic method that could be used by an attacker to undermine an anomaly-based intrusion detection system. It presents a method... [09 Jul 2008]
Analysis of Distributed Intrusion Detection Systems Using Bayesian Methods
White Paper However, it is not the attack but rather the attacker against which the networks must be defended. In computer and network security, standard approaches to intrusion detection and response attempt to... [09 Jul 2008]
Dynamic Best Practices of Vulnerability Management
White Paper Once vulnerability is discovered, it is only a matter of time before an attacker develops the worm, virus or intrusion that can take advantage of the defect. The goal of the security team is to reduce... [03 Jul 2008]
Techniques to Validate Host-Connectivity
White Paper Advanced host mapping bypasses many forms of intrusion detection systems, filters, and routers, essentially enabling an attacker to map and discover previously unknown firewalled hosts. This can let an... [03 Jul 2008]
Using Independent Auditors as Intrusion Detection Systems
White Paper Integrity tools to date rely on the operating system to function correctly, so once the operating system is compromised even a novice attacker can easily defeat these tools. A basic method in computer security is to... [30 Jun 2008]
A Game Theoretic Analysis of Intrusion Detection in Access Control Systems
White Paper A security game between the attacker and the intrusion detection system is investigated both in finite and continuous-kernel versions, where in the latter case players are associated with specific cost... [19 Jun 2008]
Adaptive Alert Throttling for Intrusion Detection Systems
White Paper If this channel can become overwhelmed with bogus data, an attacker can quickly achieve complete neutralisation of intrusion detection capability. Each time an intrusion detection system... [19 Jun 2008]
Strategic Alert Throttling for Intrusion Detection Systems
White Paper Alert flood attacks may be used to conceal malicious activity by hiding it among a deluge of false alerts sent by the attacker. Network intrusion detection systems are themselves becoming targets of... [18 Jun 2008]
A Bayesian Game Approach for Intrusion Detection in Wireless Ad Hoc Networks
White Paper It studies the achievable Nash equilibrium for the attacker/defender game in both static and dynamic scenarios. In wireless ad hoc networks, although defense strategies such as Intrusion Detection... [18 Jun 2008]
A Target-Centric Ontology for Intrusion Detection
White Paper The ontology is based upon an analysis of over 4,000 classes of computer intrusions and their corresponding attack strategies and is categorized according to: system component targeted, means of attack, consequence of attack and location... [12 Jun 2008]
Mimicry Attacks on Host-Based Intrusion Detection Systems
First, it introduces the notion of a mimicry attack, which allows a sophisticated attacker to cloak their intrusion to avoid detection by the Intrusion Detection Systems (IDS). This... [03 Jun 2008]
Mimicry Attacks on Host-Based Intrusion Detection Systems
White Paper First, it introduces the notion of a mimicry attack, which allows a sophisticated attacker to cloak their intrusion to avoid detection by the Intrusion Detection Systems (IDS). This... [03 Jun 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. This paper... [21 May 2008]
Real-Time Multistage Attack Awareness Through Enhanced Intrusion Alert Clustering
White Paper For many networks and their system administrators, the alerts generated by Snort are the primary indicators of network misuse and attacker activity. Correlation and fusion of intrusion alerts to provide... [11 Apr 2008]
Weaknesses in Wireless LAN Session Containment
White Paper Using the traffic analysis techniques described in this paper, an attacker can fingerprint the type of wireless LAN intrusion detection system deployed to monitor and protect the wireless network, and... [06 Dec 2007]
