DepCoS – RELCOMEX is an annual series of conferences organized by the Institute of Computer Engineering, Control and Robotics (CECR), Wrocław University of Technology, since 2006. Its idea came from the heritage of the other two cycles of events: RELCOMEX Conferences (1977 – 89) and Microcomputer Schools (1985 – 95) which were then organized by the Institute of Engineering Cybernetics, the previous name of CECR. In contrast to those preceding meetings focused on the conventional reliability analysis, the DepCoS mission is to develop a more comprehensive approach to computer system performability, which is now commonly called dependability. Contemporary technical systems are integrated unities of technical, information, organization, software and human resources. Diversity of the processes being realized in the system, their concurrency and their reliance on in-system intelligence significantly impedes construction of strict mathematical models and calls for application of intelligent and soft computing methods. The submissions included in this volume illustrate variety of problems that need to be explored in the dependability analysis: methodologies and practical tools for modeling, design and simulation of the systems, security and confidentiality in information processing, specific issues of heterogeneous, today often wireless, computer networks, or management of transportation networks.

Intrusion detection is not for the faint at heart. But, if you are a network administrator chances are you're under increasing pressure to ensure that mission-critical systems are safe--in fact impenetrable--from malicious code, buffer overflows, stealth port scans, SMB probes, OS fingerprinting attempts, CGI attacks, and other network intruders.Designing a reliable way to detect intruders before they get in is a vital but daunting challenge. Because of this, a plethora of complex, sophisticated, and pricy software solutions are now available. In terms of raw power and features, SNORT, the most commonly used Open Source Intrusion Detection System, (IDS) has begun to eclipse many expensive proprietary IDSes. In terms of documentation or ease of use, however, SNORT can seem overwhelming. Which output plugin to use? How do you to email alerts to yourself? Most importantly, how do you sort through the immense amount of information Snort makes available to you?Many intrusion detection books are long on theory but short on specifics and practical examples. Not Managing Security with Snort and IDS Tools. This new book is a thorough, exceptionally practical guide to managing network security using Snort 2.1 (the latest release) and dozens of other high-quality open source other open source intrusion detection programs.Managing Security with Snort and IDS Tools covers reliable methods for detecting network intruders, from using simple packet sniffers to more sophisticated IDS (Intrusion Detection Systems) applications and the GUI interfaces for managing them. A comprehensive but concise guide for monitoring illegal entry attempts, this invaluable new book explains how to shut down and secure workstations, servers, firewalls, routers, sensors and other network devices.Step-by-step instructions are provided to quickly get up and running with Snort. Each chapter includes links for the programs discussed, and additional links at the end of the book give administrators access to numerous web sites for additional information and instructional material that will satisfy even the most serious security enthusiasts.Managing Security with Snort and IDS Tools maps out a proactive--and effective--approach to keeping your systems safe from attack.

A practical, example-driven guide to configuring even the most advanced features of pfSense 2.x Key FeaturesBuild a high-availability fault-tolerant security system with pfSense 2.xLeverage the latest version of pfSense to secure your cloud environmentA recipe-based guide that will help you enhance your on-premise and cloud security principlesBook Description pfSense is an open source distribution of the FreeBSD-based firewall that provides a platform for flexible and powerful routing and firewalling. The versatility of pfSense presents us with a wide array of configuration options, which makes determining requirements a little more difficult and a lot more important compared to other offerings. pfSense 2.x Cookbook – Second Edition starts by providing you with an understanding of how to complete the basic steps needed to render a pfSense firewall operational. It starts by showing you how to set up different forms of NAT entries and firewall rules and use aliases and scheduling in firewall rules. Moving on, you will learn how to implement a captive portal set up in different ways (no authentication, user manager authentication, and RADIUS authentication), as well as NTP and SNMP configuration. You will then learn how to set up a VPN tunnel with pfSense. The book then focuses on setting up traffic shaping with pfSense, using either the built-in traffic shaping wizard, custom floating rules, or Snort. Toward the end, you will set up multiple WAN interfaces, load balancing and failover groups, and a CARP failover group. You will also learn how to bridge interfaces, add static routing entries, and use dynamic routing protocols via third-party packages. What you will learnConfigure the essential pfSense services (namely, DHCP, DNS, and DDNS)Create aliases, firewall rules, NAT port-forward rules, and rule schedulesCreate multiple WAN interfaces in load-balanced or failover configurationsConfigure firewall redundancy with a CARP firewall failoverConfigure backup/restoration and automatic configuration-file backupConfigure some services and perform diagnostics with command-line utilitiesWho this book is for This book is intended for all levels of network administrators. If you are an advanced user of pfSense, then you can flip to a particular recipe and quickly accomplish the task at hand; if you are new to pfSense, on the other hand, you can work through the book chapter by chapter and learn all of the features of the system from the ground up.
