Insider Attack and Cyber Security: Beyond the Hacker defines the nature and scope of insider problems as viewed by the financial industry. This edited volume is based on the first workshop on Insider Attack and Cyber Security, IACS 2007. The workshop was a joint effort from the Information Security Departments of Columbia University and Dartmouth College. This book sets an agenda for an ongoing research initiative to solve one of the most vexing problems encountered in security, and includes the following topics: critical IT infrastructure, insider threats, awareness and dealing with nefarious human activities in a manner that respects individual liberties and privacy policies of organizations while providing the best protection of critical resources and services. In some sense, the insider problem is the ultimate security problem. This volume concludes with technical and legal challenges facing researchers who study and propose solutions to mitigate insider attacks.

Every type of organization is vulnerable to insider abuse, errors, and malicious attacks: Grant anyone access to a system and you automatically introduce a vulnerability. Insiders can be current or former employees, contractors, or other business partners who have been granted authorized access to networks, systems, or data, and all of them can bypass security measures through legitimate means. Insider Threat – A Guide to Understanding, Detecting, and Defending Against the Enemy from Within shows how a security culture based on international best practice can help mitigate the insider threat, providing short-term quick fixes and long-term solutions that can be applied as part of an effective insider threat program. Read this book to learn the seven organizational characteristics common to insider threat victims; the ten stages of a malicious attack; the ten steps of a successful insider threat program; and the construction of a three-tier security culture, encompassing artefacts, values, and shared assumptions. Perhaps most importantly, it also sets out what not to do, listing a set of worst practices that should be avoided.

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 One introduces the notion of insider threat and reports some data about data breaches due to insider threats. Chapter Two covers authentication and access control techniques, and Chapter Three shows how these general security techniques can be extended and used in the context of protection from insider threats. Chapter Four 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 Five. 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 Six 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 Seven, 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 Eight, the book concludes with a few remarks and additional research directions.

Insider Threat Prevention Cyber Security (ITPCS) is scary. In the first place, ITPCS challenges the most knowledgeable people in the organization. In the second, ITPCS is disastrous when it fails. A single criminal incident can completely ruin a company and render the company completely out of business (OOB). As far as I can remember, we have always faced the challenge of Insider Threat Prevention. Cyber Security, however, is the complicating factor today. Today, ITPCS has become a chronic problem for executives and the organizations they lead. You would probably be correct to guess that about forty percent of all Cyber Security incidents result from malicious insider attacks. Insider cyber-attacks are more expensive than the attacks of external hackers. While "credentialed" Insider attacks leave the most damage behind, the malicious insider attacks perpetrated by malicious outsiders through coercion often cause the most damage. Here is a perennial fact: Insider Threat Prevention is fundamentally behavioral and psychological. Highly secure technology assists ITPCS, but it is not enough. ITP begins with people, moves to process, and terminates with technology, always facilitated by people. ITP is a direct attack on an organization's information resources. Anything can be a target such as data, Intellectual Property, Trade Secrets, and Knowledge Applications. Malicious success requires Cyber Terrorists to discover where the organization's targeted information resources are located as well as the rules governing access and usage. These rules enable teams to manage data classification, access governance, data sharing, monitoring, procedures and controls, legal and cultural considerations. The missing key to stopping malicious insiders is, of course, not hiring them and selecting them out early during the customary probationary period. Since malicious insiders can operate more silently and inflict more damage than outsiders, designated managers have to pay attention to the "lateral movement" activities of their employees as they access the information systems internally and externally.

An organization‘s employees are often more intimate with its computer system than anyone else. Many also have access to sensitive information regarding the company and its customers. This makes employees prime candidates for sabotaging a system if they become disgruntled or for selling privileged information if they become greedy. Insider Comput

The malicious insider threat is one of the most nefarious of potential cyber security breaches. There have been egregious insider data thefts in the last 10 years within the government. The Unintentional Insider Threat (UIT)-the individual who is incompetent or careless and accidentally divulges sensitive information-is also a major concern. Today, the Department of Defense (DoD) expends considerable effort to identify both forms of insider threats. Meanwhile, the DoD hopes to recruit innovative information technology personnel to better meet current and emerging cyber threats to national security. Although in its infancy, organizations like the Defense Innovation Unit represent this focused effort. This thesis investigates whether innovative personnel will pose increased insider threat potential. Our preliminary conclusion is that innovative people would not pose more of a malicious insider threat, but the UIT and innovator share one trait together: risk taking. Furthermore, mental health issues and disgruntlement are two traits shared by UIT and malicious insiders. The DoD should explore screening personnel for risk-taking traits, for example with the Balloon Analogue Risk Task (BART). Finally, the DoD should continue to be alert to mental health issues, and first line supervisors should intervene quickly to help disgruntled employees.This compilation includes a reproduction of the 2019 Worldwide Threat Assessment of the U.S. Intelligence Community.Personnel with authorized access are potentially the biggest threat to the Department of Defense (DoD). The cyber actor operating from outside the DoDIN is not as dangerous. The attacker without insider access has to circumvent world-class technology, firewalls, access control lists, intrusion detection systems, and encryption just to potentially access sensitive data. In fact, in 2018, insider threats accounted for 28% of all cyber-attacks. Trusted personnel already have the access; they have permission to be "inside the wire." The trusted insider is where the most dangerous threat lies. Meanwhile, the rapid pace of cyber innovation within the DoD is necessitating recruitment of a new type of personnel. As cyber technology continues to evolve, the cyber workforce will need to evolve with it; the DoD will need innovative people to work in it and lead it. The commonplace association of innovative high tech workers with quirky personality types naturally raises the question of whether hiring an innovative workforce will foster more insider threats. The research question this thesis examines in depth is: Do innovative thinkers pose an increased insider threat? A rigorous assessment of this question, going beyond superficial impressions and stereotypes, is necessary to guide DoD policy as it builds a personnel base to meet future information security challenges.

Cyber attacks against companies and organizations can result in high impact losses that include damaged credibility, exposed vulnerability, and financial losses. Until the 21st century, insiders were often overlooked as suspects for these attacks. The 2010 CERT Cyber Security Watch Survey attributes 26 percent of cyber crimes to insiders. Numerous real insider attack scenarios suggest that during, or directly before the attack, the insider begins to behave abnormally. We introduce a method to detect abnormal behavior by profiling users. We utilize the k-means and kernel density estimation algorithms to learn a user's normal behavior and establish normal user profiles based on behavioral data. We then compare user behavior against the normal profiles to identify abnormal patterns of behavior.

Today's malware mutates randomly to avoid detection, but reactively adaptive malware is more intelligent, learning and adapting to new computer defenses on the fly. Using the same algorithms that antivirus software uses to detect viruses, reactively adaptive malware deploys those algorithms to outwit antivirus defenses and to go undetected. This book provides details of the tools, the types of malware the tools will detect, implementation of the tools in a cloud computing framework and the applications for insider threat detection.
