As data represent a key asset for today's organizations, the problem of how to protect this data from theft and misuse is at the forefront of these organizations' minds. Even though today several data security techniques are available to protect data and computing infrastructures, many such techniques--such as firewalls and network security tools--are unable to protect data from attacks posed by those working on an organization's "inside." These "insiders" usually have authorized access to relevant information systems, making it extremely challenging to block the misuse of information while still allowing them to do their jobs. This book discusses several techniques that can provide effective protection against attacks posed by people working on the inside of an organization. Chapter 1 introduces the notion of insider threat and reports some data about data breaches due to insider threats. Chapter 2 covers authentication and access control techniques, and Chapter 3 shows how these general security techniques can be extended and used in the context of protection from insider threats. Chapter 4 addresses anomaly detection techniques that are used to determine anomalies in data accesses by insiders. These anomalies are often indicative of potential insider data attacks and therefore play an important role in protection from these attacks. Security information and event management (SIEM) tools and fine-grained auditing are discussed in Chapter 5. These tools aim at collecting, analyzing, and correlating--in real-time--any information and event that may be relevant for the security of an organization. As such, they can be a key element in finding a solution to such undesirable insider threats. Chapter 6 goes on to provide a survey of techniques for separation-of-duty (SoD). SoD is an important principle that, when implemented in systems and tools, can strengthen data protection from malicious insiders. However, to date, very few approaches have been proposed for implementing SoD in systems. In Chapter 7, a short survey of a commercial product is presented, which provides different techniques for protection from malicious users with system privileges--such as a DBA in database management systems. Finally, in Chapter 8, the book concludes with a few remarks and additional research directions.
