Abstract

Usually, network security issues are of major concern for all businesses that want to keep the affirmation they are usually dealing with under strict confidentiality. These issues are not very recent, ever since information was transferred among senders and recipients, data transition has been prone to, so as to speak, attacks in order to undermine the protection and to reach out relevant or useful pieces of information. In essence, these attacks are the results of tough competition. Even though network security issues are these days associated with computerized solutions, as a matter of act, this procedure has an impressive background. As long as information has a certain value, it is undeniably prone to attack.

Chapter One: Introduction

Aim

In this thesis we describe model called Diagram of security, which extends existing UML models, specifically Deployment diagram, which is intended for modeling architecture of network systems and it is a model of cooperation between hardware and software components. In our thesis we describe the security requirements of company managers and we suggest methodology of modeling of network systems in terms of security. Diagram of security is comprehensive tool, which will examine network systems to find weaknesses in terms of security and will estimate correct security risk in the deploying or existing network system.

Research Objectives

Assessing the actual state in modeling security the following objectives were defined in the thesis:

- define a model to determine the boundaries of network system and security risk factors of network system,

- create definition of Diagram of security, allowing mathematical and graphical interpretation of the modeled system in terms of network security and will be based on the definition of UML model, namely the Deployment diagram,

- define the attributes of Diagram of security that make it possible to evaluate security properties of modeled elements,

- define analysis algorithms to detect vulnerabilities and critical path in terms of security and determine the potential risk of threats of attacks and ability of system to respond,

- implement a basic cost analysis addressing the security policy. The result of the analysis will be to serve as a basis for management decisions and enable risk management to decide on further investments in security features and method of system development.

Problem Description

Designed security model is endowed by real data from various components such as servers, firewalls, workstations and various other components and ...
