Computer Network Security System

The classic guide to network security--now fully updated!"Bob and Alice are back!" Widely regarded as the most comprehensive yet comprehensible guide to network security, the first edition of Network Security received critical acclaim for its lucid and witty explanations of the inner workings of network security protocols. In the second edition, this most distinguished of author teams draws on hard-won experience to explain the latest developments in this field that has become so critical to our global network-dependent society. "Network Security, Second Edition" brings together clear, insightful, and clever explanations of every key facet of information security, from the basics to advanced cryptography and authentication, secure Web and email services, and emerging security standards. Coverage includes: All-new discussions of the Advanced Encryption Standard (AES), IPsec, SSL, and Web securityCryptography: In-depth, exceptionally clear introductions to secret and public keys, hashes, message digests, and other crucial conceptsAuthentication: Proving identity across networks, common attacks against authentication systems, authenticating people, and avoiding the pitfalls of authentication handshakesCore Internet security standards: Kerberos 4/5, IPsec, SSL, PKIX, and X.509Email security: Key elements of a secure email system-plus detailed coverage of PEM, S/MIME, and PGPWeb security: Security issues associated with URLs, HTTP, HTML, and cookiesSecurity implementations in diverse platforms, including Windows, NetWare, and Lotus Notes The authors go far beyond documenting standards and technology: They contrast competing schemes, explain strengths and weaknesses, and identify thecrucial errors most likely to compromise secure systems. Network Security will appeal to a wide range of professionals, from those who design or evaluate security systems to system administrators and programmers who want a better understanding of this important field.

"This is an excellent text that should be read by every computer security professional and student." --Dick Kemmerer, University of California, Santa Barbara. "This is the most complete book on information security theory, technology, and practice that I have encountered anywhere!" --Marvin Schaefer, Former Chief Scientist, National Computer Security Center, NSA This highly anticipated book fully introduces the theory and practice of computer security. It is both a comprehensive text, explaining the most fundamental and pervasive aspects of the field, and a detailed reference filled with valuable information for even the most seasoned practitioner. In this one extraordinary volume the author incorporates concepts from computer systems, networks, human factors, and cryptography. In doing so, he effectively demonstrates that computer security is an art as well as a science. "Computer Security: Art and Science includes detailed discussions on: The nature and challenges of computer securityThe relationship between policy and security The role and application of cryptography The mechanisms used to implement policies Methodologies and technologies for assuranceVulnerability analysis and intrusion detection "Computer Security discusses different policy models, and presents mechanisms that can be used to enforce these policies. It concludes with examples that show how to apply the principles discussed in earlier sections, beginning with networks and moving on to systems, users, and programs. This important work is essential for anyone who needs to understand, implement, or maintain a secure network or computer system.

Security protocol notation - Security (engineering) protocol notation is a way of expressing a protocol of correspondence between entities of a dynamic system, such as a computer network. It allows reasoning about the properties of such a system, and provides a formal model, to which the BAN logic can be applied.

Network computer - A network computer is a lightweight computer system that operates exclusively via a network connection. As such, it does not have secondary storage such as a hard disk drive – it boots off the network, but runs applications locally, using its own CPU and RAM.

Computer network - A computer network is a system for communication between computers. These networks may be fixed (cabled, permanent) or temporary (as via modems or null modems).

Exploit (computer security) - An exploit is a common term in the computer security community to refer to a piece of software that takes advantage of a bug, glitch or vulnerability, leading to privilege escalation or denial of service on a computer system.

Prevent security breaches by protecting endpoint systems with Cisco Security Agent presents a detailed explanation of Cisco security solutions, showing what each element is capable of doing and how to apply the principles discussed in earlier sections, beginning with networks and moving on to systems, users, and programs. It focuses on external threats, and generally treats the computer system itself as a trusted system. Some are teenage thrill-seekers or vandals (the kind often responsible for network security; and even non-technical business leaders would learn a lot about how to maintain the Cisco Security Agent presents a clear view of the insecurity of current computer systems - once an attacker has subverted one part of a system without fine-grained security, he or she usually has access to most or all of the threats at many levels computer network security system.
