Book excerpt: ABSTRACT: Malware, or malicious software such as viruses, worms, trojan horses or rootkits, pose a grave challenge to the computer user community by obtaining unauthorized access to computer resources. Among various malware, worms interest computer security researchers immensely due to their ability to infect millions of computers in a short period of time and cause hundreds of millions of dollars in damage. Unlike other malware, worms can replicate themselves over the Internet without requiring any human involvement, which makes their damage potential very high. Security researchers strive to prevent, detect and contain worms, as well as model their propagation patterns over the Internet. Our study is primarily directed at effective detection, propagation modeling and design of worms. First, we work towards devising a detection mechanism for an advanced worm called ASCII worm which has a very high damage potential due to its ability to compromise servers that are otherwise not vulnerable to common worms. Second, we derive an exact analytical model for the propagation of permutation-scanning worms, a class of worms that employ a sophisticated propagation strategy called permutation scanning. Finally, we re-examine the classical worm propagation models in light of the pseudo-random nature of the output generated by the random number generators used by the worms, and design a worm that exploits the pseudo-randomness to achieve an optimal scanning strategy with high speed of infection, fault tolerance and low detectability.

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: The worldwide reach of the Internet allows malicious cyber criminals to coordinate and launch attacks on both cyber and cyber-physical infrastructure from anywhere in the world. This purpose of this handbook is to introduce the theoretical foundations and practical solution techniques for securing critical cyber and physical infrastructures as well as their underlying computing and communication architectures and systems. Examples of such infrastructures include utility networks (e.g., electrical power grids), ground transportation systems (automotives, roads, bridges and tunnels), airports and air traffic control systems, wired and wireless communication and sensor networks, systems for storing and distributing water and food supplies, medical and healthcare delivery systems, as well as financial, banking and commercial transaction assets. The handbook focus mostly on the scientific foundations and engineering techniques – while also addressing the proper integration of policies and access control mechanisms, for example, how human-developed policies can be properly enforced by an automated system. Addresses the technical challenges facing design of secure infrastructures by providing examples of problems and solutions from a wide variety of internal and external attack scenarios Includes contributions from leading researchers and practitioners in relevant application areas such as smart power grid, intelligent transportation systems, healthcare industry and so on Loaded with examples of real world problems and pathways to solutions utilizing specific tools and techniques described in detail throughout

Available in PDF, EPUB and Kindle. Book excerpt: As computer and communication networks become prevalent, the Internet has been a battlefield for attackers and defenders. One of the most powerful weapons for attackers is the Internet worm. Specifically, a worm attacks vulnerable computer systems and employs self-propagating methods to flood the Internet rapidly. The objective of this research is to characterize worm attack behaviors, analyze Internet vulnerabilities, and develop effective countermeasures. More specifically, some fundamental factors that enable a worm to be designed with advanced scanning methods are presented and investigated through mathematical modeling, simulations, and real measurements.
