Download or read book Building Internet Firewalls written by Elizabeth D. Zwicky and published by "O'Reilly Media, Inc.". This book was released on 2000-06-26 with total page 897 pages. Available in PDF, EPUB and Kindle. Book excerpt: 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.

Download or read book On the Modular Verification and Design of Firewalls written by Hrishikesh Bhattacharya and published by . This book was released on 2012 with total page 210 pages. Available in PDF, EPUB and Kindle. Book excerpt: Firewalls, packet filters placed at the boundary of a network in order to screen incoming packets of traffic (and discard any undesirable packets), are a prominent component of network security. In this dissertation, we make several contributions to the study of firewalls. 1. Current algorithms for verifying the correctness of firewall policies use O(n[superscrip d]) space, where n is the number of rules in the firewall (several thousand) and d the number of fields in a rule (about five). We develop a fast probabilistic firewall verification algorithm, which runs in time and space O(nd), and determines whether a firewall F satisfies a property P. The algorithm is provably correct in several interesting cases -- notably, for every instance where it states that F does not satisfy P -- and the overall probability of error is extremely small, of the order of .005%. 2. As firewalls are often security-critical systems, it may be necessary to verify the correctness of a firewall with no possibility of error, so there is still a need for a fast deterministic firewall verifier. In this dissertation, we present a deterministic firewall verification algorithm that uses only O(nd) space. 3. In addition to correctness, optimizing firewall performance is an important issue, as slow-running firewalls can be targeted by denial-of-service attacks. We demonstrate in this dissertation that in fact, there is a strong connection between firewall verification and detection of redundant rules; an algorithm for one can be readily adapted to the other task. We suggest that our algorithms for firewall verification can be used for firewall optimization also. 4. In order to help design correct and efficient firewalls, we suggest two metrics for firewall complexity, and demonstrate how to design firewalls as a battery of simple firewall modules rather than as a monolithic sequence of rules. We also demonstrate how to convert an existing monolithic firewall into a modular firewall. We propose that modular design can make firewalls easy to design and easy to understand. Thus, this dissertation covers all stages in the life cycle of a firewall -- design, testing and verification, and analysis -- and makes contributions to the current state of the art in each of these fields.
