Computer security : principles and practice
free download

The course covers classic security topics, such as applied cryptography, authentication, authorization and basic security principles. Furthermore, it covers some recent topics such as web security and virtual machines security. The topics

CSI computer crime and security survey
free download

For several years, this survey perhaps the most widely quoted set of statistics in the industry showed a steady drop in average estimated losses due to cybercrime. It seemed counterintuitive to some experts, accustomed to seeing the worst of the crime thats out there.

Sequence matching and learning in anomaly detection for computer security
free download

Two problems of importance in computer security are to 1) detect the presence of an intruder masquerading as the valid user and 2) detect the perpetration of abusive actions on the part of an otherwise innocuous user. We have developed an approach to these problems that

Computer security incident handling guide
free download

Computer security incident response has become an important component of information technology (IT) programs. Because performing incident response effectively is a complex undertaking, establishing a successful incident response capability requires substantial

Introduction to computer security
free download

Catalog Description (3 credits) Develop an understanding of the principles of computer systems security (confidentiality, integrity and availability), especially as it crosses layers of abstraction (application layer, operating system, hardware and network). Students will learn

Guide to computer security log management
free download

A log is a record of the events occurring within an organizations systems and networks. Logs are composed of log entries; each entry contains information related to a specific event that has occurred within a system or network. Many logs within an organization contain

Robust Support Vector Machines for Anomaly Detection in Computer Security .
free download

MITs Lincoln Labs to study intrusion detection systems, the performance of robust support vector machines (RVSMs) was compared with that of conventional support vector machines and nearest neighbor classifiers in separating normal usage profiles from intrusive profiles

Improving computer security using extended static checking
free download

We describe a method for finding security flaws in source code by way of static analysis. The method is notable because it allows a user to specify a wide range of security properties while also leveraging a set of predefined common flaws. It works by using an automated

Computer security strength risk: A quantitative approach
free download

When attacking a software system is only as difficult as it is to obtain a vulnerability to exploit, the security strength of that system is equivalent to the market price of such a vulnerability. In this dissertation I show how security strength can be measured using market means, how

How much is enough A risk management approach to computer security
free download

The research for this working paper was sponsored in part by the Consortium for Research on Information Security and Policy (CRISP). CRISP was created at Stanford University to develop a better analytical and policy understanding of national and international security In the mid-1990s, when I was a graduate student studying machine learning, someone broke into a deans computer account and behaved in a way that most deans never would: There was heavy use of system resources very early in the morning. I wondered why there

Approaches to Online Learning and Concept Drift for User Identification in Computer Security .
free download

The task in the computer security domain of anomaly detection is to characterize the behaviors of a computer user (the valid, or normaluser) so that unusual occurrences can be detected by comparison of the current input stream to the valid users profile. This task

The best available technologies for computer security
free download

For more than a decade, government, industry, and academic centers have investigated techniques for developing computer systems that can be trusted to enforce military security rules. A good deal has been learned about the problem, and a number of approaches have

The CISSP prep Guide: Mastering the ten domains of Computer Security
free download

You hold in your hand a key, a key to unlocking the secrets of the world of information systems security. This world will present you with many new challenges and rewards, because information systems security is the latest frontier in mans continuing search for

Mental Models of Computer Security Risks.
free download

Improved computer security requires improvements in risk communication to naive end users. Efficacy of risk communication depends not only on the nature of the risk, but also on the alignment between the conceptual model embedded in the risk communication and the

Concepts and terminology for computer security
free download

The essay begins by defining what is meant by computer security and describing why it is important to constrain the definition to protection that can be meaningfully provided with a significant degree of assurance within computer systems. The theory of computer security ³

A structured approach to computer security
free download

Security and dependability are two closely connected areas. Recently, some attempts have been made to integrate the two concepts by integrating security into the more general topic of dependability. This paper describes security concepts and gives a survey of security

The National Institute of Standards and Technology (NIST) developed this document in furtherance of its statutory responsibilities under the Federal Information Security Management Act (FISMA) of 2002, Public Law 107-347. NIST is responsible for developing

An undergraduate track in computer security
free download

To better prepare our graduates to face the challenges in computer and information security, in Fall 2002, Towson University launched an undergraduate track in computer security for the computer science majors. This paper describes the motivation behind this track and

Security across the curriculum: using computer security to teach computer science principles
free download

Insuring that individuals who obtain computer science degrees have a sound foundation in security principles is becoming increasingly important as the worldwide connectivity of our networks grows and the number of security incidences increases. Increasing the number of
