Malicious activity represents a credible and growing threat to the confidentiality, integrityand availability of information assets in modern computing environments. Intrusion detection, which studies the detection and mitigation of cyber-attacks, is a mature area of researchthat has led to the development of widely used applications called Intrusion Detection Systems(IDS). These IDSs typically focus on analyzing low-level system and network data (e.g., systemcalls, network packets) using rule-based and anomaly-based techniques to detect obviousmalicious activity such as probes (e.g., portscanning) and denial-of-service (DoS) attacks. However, with the evolution of computer systems, networks and the accompanying growth of theInternet and its user base, the nature of cyber-attacks has become more sophisticated.^Thereis an increasing prevalence of attacks that are multi-stage and goal oriented - the attacks arenot designed simply to take down a system and affect its availability, but may involve intrusionfollowed by actions that affect confidentiality and integrity (e.g., accessing unauthorized data)of the system or network in question. Several techniques for the detection of such attacks havebeen proposed in the literature, mainly as aids to forensic analysis (i.e., they are not online). There has also been a lack of in-depth study into recognizing the semantics of attack scenarioprogression. As a consequence, prior approaches have not been able to provide analysts withadequate awareness of evolving attacks which might enable timely mitigation. The thrust of this dissertation is the development of cyber-attack detection and comprehensiontechniques that focus on high-level application data (IDS events, logfile entries, userqueries etc.) as opposed to network packets and system calls.^By restricting analysis to high-leveldata, attack semantics are better captured and represented; this benefit is leveraged to provideimproved awareness of attacks. Online detection techniques using rule-based and learning-based approaches are developed that aim to provide security analysts with the means for attack recognition(when is an attack happening?) and comprehension (attack semantics). In the first part of this dissertation, attack scenario detection is approached from aSituation Awareness (SA) perspective. Events from IDS sensors are considered as atomic elementsthat define a situation (Level 1 SA) and a semantics-based attack modeling framework isused to understand the overall meaning conveyed by situation elements (Level 2 SA).^A rulebasedapproach to event correlation and suitable visualization tools enable effective comprehensionthat provides analysts with a predictive and mitigative capability (Level 3 SA).A learning-based approach to attack scenario comprehension in a distributed networkis the focus of the second part of the dissertation. Macro-level activity in a computernetwork is analyzed with a view to detecting abnormal behavior that may indicate possible maliciousactivity.^Events generated by multiple heterogeneous sensors such as IDSs and systemlogs are used to define a high-dimensional state vector representing overall activity; PrincipalComponent Analysis is used to learn characteristic patterns of activity and aid in anomaly detection. A suitable modeling framework and visualization techniques are also presented for thisapproach. In the final part of this dissertation, a very specific attack model in a specific applicationenvironment is analyzed - that of insider attacks against relational databases. A datacentricapproach that models queries based on the data returned by their execution, as opposed totheir SQL-expression syntax (syntax-centric), is the thrust of this work.^Various types of queryanomalies are analyzed from the data-centric viewpoint and efficient techniques for detectingpotential attacks are developed. The techniques that are presented as part of this dissertation are tested and validated with test and attack datasets generated in realistic environments. Attack detection through applicationdata analysis is found to offer significant benefits to the practice of cyber-security - easeof data handling and improved ability to capture the semantics of malicious activity are some ofthe important contributions.

This textbook presents a proven, mature Model-Based Systems Engineering (MBSE) methodology that has delivered success in a wide range of system and enterprise programs. The authors introduce MBSE as the state of the practice in the vital Systems Engineering discipline that manages complexity and integrates technologies and design approaches to achieve effective, affordable, and balanced system solutions to the needs of a customer organization and its personnel. The book begins with a summary of the background and nature of MBSE. It summarizes the theory behind Object-Oriented Design applied to complex system architectures. It then walks through the phases of the MBSE methodology, using system examples to illustrate key points. Subsequent chapters broaden the application of MBSE in Service-Oriented Architectures (SOA), real-time systems, cybersecurity, networked enterprises, system simulations, and prototyping. The vital subject of system and architecture governance completes the discussion. The book features exercises at the end of each chapter intended to help readers/students focus on key points, as well as extensive appendices that furnish additional detail in particular areas. The self-contained text is ideal for students in a range of courses in systems architecture and MBSE as well as for practitioners seeking a highly practical presentation of MBSE principles and techniques.

Every day, people interact with numerous computer systems, networks, and services that require the exchange of sensitive data. However, the Internet is a highly distributed system operated by many different entities and as such should not be trusted by end users. Users, whether consumers or businesses, retain no control over how their information is routed among the many networks that comprise the Internet. Therefore, there is a strong need for cryptographic protocols to authenticate, verify trust, and establish a secure channel for exchanging data. This chapter presents a series of projects and demonstrations for systems and networking professionals who want to increase their comprehension of security concepts and protocols. The material presented here is derived from existing courses taught by the authors in the areas of cryptography, network security, and wireless security.
