Computer networks are indispensible, but they also are not secure. With the proliferation of security threats, many people and companies are looking for ways to increase the security of their networks and data. Before you can effectively implement security technologies and techniques, you need to make sense of this complex and quickly evolving world of hackers and malware, as well as the tools to combat them. Network Security First-Step, Second Edition explains the basics of network security in easy-to-grasp language that all of us can understand. This book takes you on a guided tour of the core technologies that make up and control network security. Whether you are looking to take your first step into a career in network security or simply are interested in gaining knowledge of the technology, this book is for you!

Authored by a leading networking instructor and bestselling author, "Network Security First-Step" is a novice-friendly introduction to the world of network security. It tackles the different terminology, products, services, and elements of networking security, including both the threats and the defenses.

Learn about network security, including the threats and the ways a network is protected from them. The book also covers firewalls, viruses and virtual private networks.

There is no sorcery to implementing proper information security, and the concepts that are included in this fully updated second edition are not rocket science. Build a concrete foundation in network security by using this hands-on guide. Examine the threats and vulnerabilities of your organization and manage them appropriately. Includes new chapters on firewalls, wireless security, and desktop protection. Plus, plenty of up-to-date information on biometrics, Windows.NET Server, state laws, the U.S. Patriot Act, and more.

This book provides a practical, up-to-date, and comprehensive survey of network-based and Internet-based security applications and standards. This books covers e-mail security, IP security, Web security, and network management security. It also includes a concise section on the discipline of cryptography--covering algorithms and protocols underlying network security applications, encryption, hash functions, digital signatures, and key exchange. For system engineers, engineers, programmers, system managers, network managers, product marketing personnel, and system support specialists.

In the five years since the first edition of this classic book was published, Internet use has exploded. The commercial world has rushed headlong into doing business on the Web, often without integrating sound security technologies and policies into their products and methods. The security risks--and the need to protect both business and personal data--have never been greater. We've updated Building Internet Firewalls to address these newer risks. What kinds of security threats does the Internet pose? Some, like password attacks and the exploiting of known security holes, have been around since the early days of networking. And others, like the distributed denial of service attacks that crippled Yahoo, E-Bay, and other major e-commerce sites in early 2000, are in current headlines. Firewalls, critical components of today's computer networks, effectively protect a system from most Internet security threats. They keep damage on one part of the network--such as eavesdropping, a worm program, or file damage--from spreading to the rest of the network. Without firewalls, network security problems can rage out of control, dragging more and more systems down. Like the bestselling and highly respected first edition, Building Internet Firewalls, 2nd Edition, is a practical and detailed step-by-step guide to designing and installing firewalls and configuring Internet services to work with a firewall. Much expanded to include Linux and Windows coverage, the second edition describes: Firewall technologies: packet filtering, proxying, network address translation, virtual private networks Architectures such as screening routers, dual-homed hosts, screened hosts, screened subnets, perimeter networks, internal firewalls Issues involved in a variety of new Internet services and protocols through a firewall Email and News Web services and scripting languages (e.g., HTTP, Java, JavaScript, ActiveX, RealAudio, RealVideo) File transfer and sharing services such as NFS, Samba Remote access services such as Telnet, the BSD "r" commands, SSH, BackOrifice 2000 Real-time conferencing services such as ICQ and talk Naming and directory services (e.g., DNS, NetBT, the Windows Browser) Authentication and auditing services (e.g., PAM, Kerberos, RADIUS); Administrative services (e.g., syslog, SNMP, SMS, RIP and other routing protocols, and ping and other network diagnostics) Intermediary protocols (e.g., RPC, SMB, CORBA, IIOP) Database protocols (e.g., ODBC, JDBC, and protocols for Oracle, Sybase, and Microsoft SQL Server) The book's complete list of resources includes the location of many publicly available firewall construction tools.

Introduces the authors' philosophy of Internet security, explores possible attacks on hosts and networks, discusses firewalls and virtual private networks, and analyzes the state of communication security.

Your first step into the world of TCP/IP No TCP/IP experience required Includes clear and easily understood explanations Makes learning easy Your first step to understanding TCP/IP begins here! Learn TCP/IP basics Discover the power of TCP/IP components and subcomponents Use hands-on activities to understand TCP/IP Benefit from examples that illustrate the power of TCP/IP Welcome to the world of TCP/IP! TCP/IP is the world’s de facto communications protocol. It is the official protocol of the Internet and, consequently, has become the predominant communications protocol suite in many private networks and internetworks. No TCP/IP experience needed! TCP/IP First-Step explores TCP/IP concepts in a reader-friendly manner that assumes no previous experience. Learn about packetized data transfer, open networking, reference models, and standards bodies. Understand the architecture of the TCP/IP protocol suite and learn about its components, functions, and respective uses. TCP/IP First-Step helps you understand TCP/IP’s role in the network.
