Computer Network Security

Computer network security is treated here as both a practical challenge and a mathematical one. These proceedings gather research presented at MMM-ACNS 2003, an international workshop devoted to the methods, models, and architectures behind secure computer networks and information systems.

The papers range across security foundations and real-world applications, giving readers a research-oriented view of how specialists approached network protection, detection, and trust at the time.

Security models, examined from the ground up

One central thread is the use of formal and mathematical methods to reason about security. Contributions address models and architectures, security-policy management, protocol analysis, and the evaluation of secure systems. This focus makes the collection particularly relevant to readers interested in how security claims can be expressed and assessed—not only implemented.

From intrusion detection to access control

Other sections explore intrusion detection, including anomaly-based approaches and the analysis of attacks, alongside public-key distribution, authentication, and access control. Together, these topics show how network defense depends on multiple connected decisions: recognizing suspicious behavior, establishing identity, and determining what authenticated users or systems may do.

Cryptography, steganography, and applied research

The proceedings also cover mathematical foundations and applied techniques in cryptography and steganography. Invited contributions broaden the discussion to subjects including distributed forensics, email security, and insider attacks.

For readers following security research

This edited volume is suited to researchers, graduate students, and security professionals looking for conference papers on the formal and applied dimensions of computer network security. As proceedings from a 2003 workshop, it documents research from that period rather than serving as a guide to current security practice.
