New to UNIX and looking for a book to help you get acquainted with UNIX?
Not so new to UNIX but looking to expand your knowledge?
A programmer looking for a guide to UNIX as a reference and a teaching guide for
Perl, awk, and the shells?
A beginning system administrator looking to learn how to install UNIX or how to
connect your UNIX to a network?
A system administrator looking for a reference guide or maybe just wanting to expand
A curious soul wanting to know everything about UNIX?
If any of these is true, you are holding the right book.
"Network and system security" provides focused coverage of network and system security technologies. It explores practical solutions to a wide range of network and systems security issues. Chapters are authored by leading experts in the field and address the immediate and long-term challenges in the authors’ respective areas of expertise. Coverage includes building a secure organization, cryptography, system intrusion, UNIX and Linux security, Internet security, intranet security, LAN security; wireless network security, cellular network security, RFID security, and more.

Note that we are intentionally leaving out certain systems because they are too complicated to be
appropriately handled in the time permitted. These services are covered in detail in courses from the
SANS Unix Security curriculum:
• NTP, Apache, DNS, and Sendmail are all covered in the Running Unix Applications Securely
course (day four of the curriculum).
• Topics in Unix Security (day three) spends half a day talking about SSH.
• RPC-based applications (including NFS and NIS) and vulnerabilities are covered in more detail in
the Common Unix Vulnerabilities class (day one)....
Unix was developed by AT&T in the late 1960s and early 1970s, and was freely
distributed among a number of major universities during this time. Concurrently,
these universities were developing the network that evolved into the Internet.
The protocol wars are over and TCP/IP won. TCP/IP is now universally recognized as the pre-eminent
communications protocol for linking together diverse computer systems. The importance of interoperable
data communications and global computer networks is no longer debated. But that was not always the
case. When I wrote the first edition of this book, IPX was far and away the leading PC communications
protocol. Microsoft did not bundle communications protocols in their operating system.
Sử dụng Windows cho các dịch vụ Unix
Bạn có muốn chạy các ứng dụng tốt nhất trên cả hai hệ điều hành Windows và Unix? Trong bài viết này chúng tôi sẽ giới thiệu cho các bạn về một tùy chọn cho công việc này: Thành phần Posix của Microsoft. Nó sẽ khiến các ứng dụng của Unix cho rằng chúng đang sử dụng các ứng dụng Unix nhưng thực sự khi đó chúng đang sử dụng Windows.
Build your network once using cfengine, and the network build will work, without user intervention, on any hardware you prefer. Automating Linux and Unix System Administration, Second Edition is unique in its focus on how to make the system administrator’s job easier and more efficient: instead of just managing the system administrator’s time, the book explains the technology to automate repetitive tasks and the methodology to automate successfully.
This second edition of Network security hacks offers 125 concise and practical hacks, including more information for Windows administrators, hacks for wireless networking (such as setting up a captive portal and securing against rogue hotspots), and techniques to ensure privacy and anonymity, including ways to evade network traffic analysis, encrypt email and files, and protect against phishing attacks. System administrators looking for reliable answers will also find concise examples of applied encryption, intrusion detection, logging, trending and incident response.
Networking with UNIX-Type of Operating Systems
Describe the origins and history of the UNIX operating system
Identify similarities and differences between popular implementations of UNIX
Describe the features and capabilities of servers running Solaris, Linux, and Mac OS X Server
Explain and execute essential UNIX commands
Install and configure Linux on an Intel-based PC

Explain how computers running other operating systems can connect to UNIX servers...
Welcome to Unix and Linux, security for these operating systems is a complete paradigm shift from
Windows. Unix has been around a lot longer. The source code for Linux is freely available, so
would be attackers are free to examine it and test it for holes such as buffer overflows and deadlock
Like most operating systems in the last 40 years, Unix uses a hierarchical "tree-structured" file
system (interestingly, tree-structure and other aspects of the Unix file system are a direct result of
the original Unix developers being influenced by the Multics project they had been working on).
Directories contain files and subdirectories which, may in turn, contain other files and
subdirectories, and so on.
Every aspect of a network-storage, file transfers, backup-depends on the filesystem for structure, functionality, and integrity. Surprisingly, UNIX-the operating system of choice for mission-critical networks-has historically had little documentation on its filesystem structures. Written by Steve Pate, a sen-ior member of the VERITAS Filesystems Group, this book sheds light on the inner workings of UNIX filesystems and gives you the know-how to fine-tune your UNIX filesystems for optimal performance.
We will review backup strategies, techniques and other practices that make system and data recovery
a reliable and viable option when data loss occurs.
Superb backup tools exist for the Windows platform. A recent SANS Institute survey indicates that
several backup programs are in wide use. Veritas’ (formerly Seagate’s) BackupExec and Computer
Associates’ ARCServe programs were the most popular products in this survey. Legato’s Networker
is also represented and is a good tool for managing backups in a combined Windows/Unix network....
Debugging là nghệ thuật của loại bỏ các lỗi từ phần mềm. Các phần mềm có thể được code, tài liệu, hoặc bất kỳ
sản phẩm trí tuệ khác. Ở đây, chúng tôi sẽ xem xét lý lỗi của chương trình máy tính (hoặc thư viện)
viết bằng C hoặc C + + trong môi trường Unix. Hầu hết nó cũng áp dụng đối với các thủ tục và biên soạn
ngôn ngữ hướng đối tượng như Pascal, Modula và Mục tiêu C.
There are hundreds--if not thousands--of techniques used to compromise both Windows and Unix-based systems. Malicious code and new exploit scripts are released on a daily basis, and each evolution becomes more and more sophisticated. Keeping up with the myriad of systems used by hackers in the wild is a formidable task, and scrambling to patch each potential vulnerability or address each new attack one-by-one is a bit like emptying the Atlantic with paper cup.
