ZDNet Dictionary Definition
- Anomaly
- Abnormality or deviation. Pronounced "uh-nom-uh-lee," it is a favorite word among computer people when complex systems produce output that is inexplicable. See software conflict and anomaly detection.

- Compass for iPhone 1.0 (Mobile)
- You just have to see the sun and know the time to determine the north direction. Use it for all your outdoor activities whether it is hiking, biking or for a boy scout camp. This compass is not affected by magnetic anomalies.

- Anomaly Intrusion Detection System Using Hierarchical Gaussian Mixture Model
- Intrusion Detection Systems have been widely used to overcome security threats in computer networks and to identify unauthorized use, misuse, and abuse of computer systems. Anomaly-based approaches in Intrusion Detection Systems have the advantage of being able to detect unknown attacks; they look for patterns that deviate from the normal...

- How OpenDNS, PowerDNS and MaraDNS remained unaffected by the DNS cache poisoning vulnerability
- The short answer is being paranoid about tackling a known vulnerability. It's 2001, and Daniel J. Bernstein DJB, author of the then popular djbdns security-aware DNS implementation, is applying basic math principles to raise awareness on what's to turn into the "sky is falling" critical Internet vulnerability in 2008, in...

- Boosting Web Intrusion Detection Systems by Inferring Positive Signatures
- This paper presents a new approach to anomaly-based network intrusion detection for web applications. This approach is based on dividing the input parameters of the monitored web application in two groups: the "Regular" and the "Irregular" ones, and applying a new method for anomaly detection on the "Regular" ones based...

- IDGraphs: Intrusion Detection and Analysis Using Histographs
- Traffic anomalies and attacks are commonplace in today's networks and identifying them rapidly and accurately is critical for large network operators. For a statistical Intrusion Detection System IDS, it is crucial to detect at the flow-level for accurate detection and mitigation. However, existing IDS systems offer only limited support for...

- Bayesian Event Classification for Intrusion Detection
- Intrusion Detection Systems IDSs attempt to identify attacks by comparing collected data to predefined signatures known to be malicious (misuse-based IDSs) or to a model of legal behavior (anomaly-based IDSs). Anomaly-based approaches have the advantage of being able to detect previously unknown attacks, but they suffer from the difficulty of...

- ATLANTIDES: An Architecture for Alert Verification in Network Intrusion Detection Systems
- This paper presents an architecture1 designed for alert verification (i.e., to reduce false positives) in network intrusion-detection systems. The technique in this paper is based on a systematic and automatic anomaly-based analysis of the system output, which provides useful context information regarding the network services. The false positives raised by...

- SPHINX: An Anomaly-Based Web Intrusion Detection System
- This paper presents Sphinx, an anomaly-based web intrusion detection system. Sphinx analyzes the parameters sent to the web server, infers the "Type" of each parameter and combines different techniques to detect attacks, specifically designed to cope with each parameter type. Sphinx like the widely known ModSecurity is implemented as an...

- Compatibility Is Not Transparency: VMM Detection Myths and Realities
- Recent work on applications ranging from realistic honeypots to stealthier rootkits has speculated about building transparent VMMs - VMMs that are indistinguishable from native hardware, even to a dedicated adversary. This paper surveys anomalies between real and virtual hardware and consider methods for detecting such anomalies, as well as possible...

- A Bayesian Networks in Intrusion Detection Systems
- Intrusion Detection Systems IDSs have been widely used to overcome security threats in computer networks. Anomaly-based approaches have the advantage of being able to detect previously unknown attacks, but they suffer from the difficulty of building robust models of acceptable behaviour which may result in a large number of false...

- TCP Anomalies: Identification and Analysis
- Passive measurements have recently received large attention from the scientific community as a mean, not only for traffic characterization, but also to infer critical protocol behaviors and network working conditions. This paper focuses on passive measurements of TCP traffic, main component of traffic. In particular, it proposes a heuristic technique...

- Firewall Rules Analysis
- This paper proposes a method to analyze the firewall policy or rule-set using Relational Algebra and Raining 2D-Box Model. It can discover all the anomalies in the firewall rule-set in the format that is usually used by many firewall products such as Cisco Access Control List, IPTABLES, IPCHAINS and Check...

- POSEIDON: A 2-Tier Anomaly-Based Network Intrusion Detection System
- Intrusion Detection Systems IDSs were introduced by Anderson and formalized later by Denning. Nowadays, there exist two main types of network intrusion detection methods: anomaly-based and signature-based. In signature-based methods, a characteristic trait of the intrusion is developed off-line, and then loaded in the intrusion database before the system can...
