Book excerpt: Internet worms are self-replicating malware programs that use the Internet to replicate themselves and propagate to other vulnerable nodes without any user intervention. In addition to consuming the valuable network bandwidth, worms may also cause other harms to the infected nodes and networks. Currently, the economic damage of Internet worms' attacks has reached a level that made early detection and mitigation of Internet worms a top priority for security professionals within enterprise networks and service providers. While the majority of legitimate Internet services rely on the Domain Name System (DNS) to provide the translation between the alphanumeric human memorizable host names and their corresponding IP addresses, scanning worms typically use numeric IP addresses to reach their target victims instead of domain names and hence eliminate the need for DNS queries before new connections are established by the worms. Similarly, modern mass-mailing worms employ their own SMTP engine to bypass local mail servers security measures. However, they still rely on the DNS servers for locating the respective mail servers of their intended victims. Creating host-based Mail eXchange (MX) requests is a violation of the typical communication pattern because these requests are supposed to only take place between mail servers and DNS servers. Several researchers have noted that the correlation of DNS queries with outgoing connections from the network can be utilized for the detection zero-day scanning worms and mass-mailing worms. In this work, we implement an integrated system for the detection and mitigation of zero-day scanning and mass-mailing worms. The detection engine of our system utilizes the above mentioned DNS anomalies of the worm traffic. Once a worm is detected, the firewall rules are automatically updated in order to isolate the infected host. An automatic alert is also sent to the user of the infected host. The system can be configured such that the user response to this alert is used to undo the firewall updates and hence helps reduce the interruption of service resulting from false alarms. The developed system has been tested with real worms in a controlled network environment. The obtained experimental results confirm the soundness and effectiveness of the developed system.

Available in PDF, EPUB and Kindle. Book excerpt: As wireless networks become more commonplace, it is important to have methods to detect attacks against them. We have surveyed current open source and commercial wireless intrusion detection systems, and we present our findings. An intrusion detection system utilizing cross-layer detection, which has been designed and implemented, is described. Kismet, in conjunction with Snort and a custom developed CPU usage monitoring tool, is used to detect worm attacks on wireless networks. The process of designing and implementing a computer worm to test the accuracy of the developed system is detailed. The design, implementation, and configuration of the wireless intrusion detection system are presented. After testing how well this system detects the worm, the results are given and discussed, which indicate that the tools we use work well together and can accurately detect a worm attack. We include a discussion on how our intrusion detection system can be broadened into a more useful general framework that can be used in different environments to detect different attacks. Conclusions about the performance of this system and directions of future research are included at the end.

Book excerpt: Abstract: "The polymorphic variety of Internet worms presents a formidable challenge to network intrusion detection and methods designed to extract payload signatures for worm containment. Recently, several systems, including Earlybird and Polygraph, have been proposed, based on efficient processing of payloads to extract signatures that are either explicitly indicative of an attack (exploit code strings) or which have unusual statistical character (content prevalence, address dispersion) consistent with worm activity. While these works are seminal, these systems have limitations that affect accuracy of the extracted signatures and/or practicability of the system's deployment. Earlybird's signature extraction is fragile to polymorphism, while Polygraph makes assumptions about data availability and the accuracy of front-end flow classification. This method also possesses high complexity. We propose a new method which, fundamentally, integrates header-based multidimensional flow clustering as front-end processing, with signature extraction performed, separately, solely on each cluster in the (small) subset of identified suspicious clusters. Front-end clustering improves purity of the (separate) signature pools and also reduces complexity. We apply a 'suffix tree' approach to signature extraction, gleaning both length and frequency information. We demonstrate efficacy of our approach on a (background) trace taken from a /24 in Taiwan, which we salt with worm traffic based on two realistic polymorphic mechanisms that we propose. Since there is a dearth of public data for such testing, we have also made an anonymized version of this trace available, based on randomized headers and fingerprinted payloads."

Available in PDF, EPUB and Kindle. Book excerpt: ABSTRACT: In the recent decade, network system and e-commerce models can go to every "corner" of our world. While people enjoy such unprecedented convenience and happiness, hackers unceasingly "crack" the security of the network. In particular, Denial of Service (DoS) attacks have become a very concerning issue of network security. Research on network intrusion detection systems has been widely undertaken, including the development of several feasible systems such as AAFID, EMERALD and GrIDS. This thesis seeks to design and implement a host-based and event-based detector, which is a part of the intrusion detection system in CONS lab. The designed detector can provide an upper level controller, such as a coordinator, with the capacity to start, stop or reconfigure the system. The detector conducts a fast detection and response based on its tree-like data buffer. An aging policy is applied to increase the durable detection capacity and usage time of the fast detection data buffer. Besides detecting the failure of login events by the host, the analysis and detection of successful login events draws the designed detector's interest. A combination of two detection results can enhance the intrusion detection possibilities and accuracy. A compressed log file created and maintained by the detector makes it possible to recover a detection system and launch a post-event polling analysis, if needed. An object-oriented language makes the detector more generic and scalable for further development.
