There is a spate of papers and tools on using Modeling and Simulation (M&S) for testing Denial of Service - (DoS), virus and worm (Propagation, attacks) against computer networks, but this is not the whole story, there are no explicit M&S tools for testing computer/network security and network attack modeling. In other words, it seems that Computer Simulation was studied and investigated in many areas but the field of Computer Security has not produced significant research results in this area to date!
Simplicity is a pillar of good cryptography. In this article, we'll cover several "acts" of simplicity, ranging from independence in modularity, reduction of complexity, and conservative threat modeling, along with a final spiel on the importance of using message authentication.
In response to the growing torrent of unsolicited bulk email, many technical schemes have been proposed and implemented to distinguish spam from legitimate mail and to block delivery of spam while letting legitimate mail through. Although none of the schemes is the "magic bullet" some of them, particularly when used in combination with each other, can help limit the amount of spam that users receive.
In Part 1 of this article series we went over some of the physical threats confronting networks. We will continue, in Part 2, to cover various other ways to help secure the workstation, and thereby further help harden the internal network from attack.
Both the Active Directory and Windows in general offer a huge degree of flexibility. Although it’s really nice to have a security model that can be custom tailored to meet your exact security needs, there is a definite downside to the way that Windows security works; it can be really complicated. Fortunately, there is a way to tell exactly what the outcome of all of those policy elements is. You can run a Resultant Set of Policy (RSOP) query. In this article, I will show you how.
SPAM is one of the biggest challenges facing Internet consumers, corporations, and service providers today. Part 1 of this article explores the Issues and Impact of Spam. Part 2 provides some insight into methods for reducing Spam.
Using the familiar Alice and Bob model, we'll take a look at the concept of integrity preservation, through the use of a MAC, or Message Authentication Code. This article will define what it is, what it does, and why it's vital in the majority of cases, although often overlooked in most of them.
In an effort to stem the fast-growing tide of web application security breaches, Acunetix today announced that it is offering free website security audits to 5,000 enterprise organizations.
This document discusses the issues and concerns that organizations may face when they apply the LUA approach to computers that run Microsoft Windows XP. This paper also describes the high-level issues that affect implementation of the LUA approach and provides useful links to other online resources that explain these concepts in more detail.
