Kerberos, the single sign-on authentication system originally developed at MIT, deserves its name. It's a faithful watchdog that keeps intruders out of your networks. But it has been equally fierce to system administrators, for whom the complexity of Kerberos is legendary.Single sign-on is the holy grail of network administration, and Kerberos is the only game in town. Microsoft, by integrating Kerberos into Active Directory in Windows 2000 and 2003, has extended the reach of Kerberos to all networks large or small. Kerberos makes your network more secure and more convenient for users by providing a single authentication system that works across the entire network. One username; one password; one login is all you need.Fortunately, help for administrators is on the way. Kerberos: The Definitive Guide shows you how to implement Kerberos for secure authentication. In addition to covering the basic principles behind cryptographic authentication, it covers everything from basic installation to advanced topics like cross-realm authentication, defending against attacks on Kerberos, and troubleshooting.In addition to covering Microsoft's Active Directory implementation, Kerberos: The Definitive Guide covers both major implementations of Kerberos for Unix and Linux: MIT and Heimdal. It shows you how to set up Mac OS X as a Kerberos client. The book also covers both versions of the Kerberos protocol that are still in use: Kerberos 4 (now obsolete) and Kerberos 5, paying special attention to the integration between the different protocols, and between Unix and Windows implementations.If you've been avoiding Kerberos because it's confusing and poorly documented, it's time to get on board! This book shows you how to put Kerberos authentication to work on your Windows and Unix systems.

SSH The Secure Shell The Definitive Guide

Release Date: 2005-05-10
Genre: Computers

Are you serious about network security? Then check out SSH, the Secure Shell, which provides key-based authentication and transparent encryption for your network connections. It's reliable, robust, and reasonably easy to use, and both free and commercial implementations are widely available for most operating systems. While it doesn't solve every privacy and security problem, SSH eliminates several of them very effectively.Everything you want to know about SSH is in our second edition of SSH, The Secure Shell: The Definitive Guide. This updated book thoroughly covers the latest SSH-2 protocol for system administrators and end users interested in using this increasingly popular TCP/IP-based solution.How does it work? Whenever data is sent to the network, SSH automatically encrypts it. When data reaches its intended recipient, SSH decrypts it. The result is "transparent" encryption-users can work normally, unaware that their communications are already encrypted. SSH supports secure file transfer between computers, secure remote logins, and a unique "tunneling" capability that adds encryption to otherwise insecure network applications. With SSH, users can freely navigate the Internet, and system administrators can secure their networks or perform remote administration.Written for a wide, technical audience, SSH, The Secure Shell: The Definitive Guide covers several implementations of SSH for different operating systems and computing environments. Whether you're an individual running Linux machines at home, a corporate network administrator with thousands of users, or a PC/Mac owner who just wants a secure way to telnet or transfer files between machines, our indispensable guide has you covered. It starts with simple installation and use of SSH, and works its way to in-depth case studies on large, sensitive computer networks.No matter where or how you're shipping information, SSH, The Secure Shell: The Definitive Guide will show you how to do it securely.

Genre: Computers

Sie können noch so viel in Hardware, Software und Abwehrmechanismen investieren, absolute Sicherheit für Ihre IT-Infrastruktur wird es nicht geben. Wenn Hacker sich wirklich anstrengen, werden sie auch in Ihr System gelangen. Sollte das geschehen, müssen Sie sowohl technisch als auch organisatorisch so aufgestellt sein, dass Sie die Gegenwart eines Hackers erkennen und darauf reagieren können. Sie müssen in der Lage sein, einen Zwischenfall zu deklarieren und die Angreifer aus Ihrem Netzwerk zu vertreiben, bevor sie erheblichen Schaden anrichten. Das ist Network Security Monitoring (NSM). Lernen Sie von dem leitenden Sicherheitsanalytiker Sanders die Feinheiten des Network Security Monitoring kennen. Konzepte verstehen und Network Security Monitoring mit Open-Source-Tools durchführen: Lernen Sie die drei NSM-Phasen kennen, um diese in der Praxis anzuwenden. Die praktische Umsetzung der NSM erfolgt mit vielen Open-Source-Werkzeugen wie z. B. Bro, Daemonlogger, Dumpcap, Justniffer, Honeyd, Httpry, Netsniff-NG, Sguil, SiLK, Snorby Snort, Squert, Suricata, TShark und Wireshark. Anhand von ausführlichen Beispielen lernen Sie, die Tools effizient in Ihrem Netzwerk einzusetzen.
