Free Real World Linux Security
I am a senior engineer for network security operations. I read "Real World Linux Security" (RWLS) to learn more about best practices for securing Linux servers. Author Bob Toxen has clearly "been around the block," and in some cases he even helped "build" it. Not everyone had the fortune to study at Berkeley with the giants of UNIX! While parts of RWLS are too advanced for some (I was overwhelmed at times), it deserves to be read by serious security practioners.Anyone administering Linux systems will learn at least one security improvement from RWLS. For example, I applied Bob's suggestion to prevent X from listening on the 6000-series TCP ports. Youngsters will learn why password files incorporate a "salt" and how the "sticky bit" prevents file deletion under certain conditions. Graybeards may enjoy the tech history, like the origin of the word "spam" for unsolicited commercial email.
RWLS' strongest feature is Bob's commitment to defending his security suggestions. He doesn't just provide instructions. He states the problem, its origin, how to resolve it, other options, and finally defends his solution. One might disagree with his conclusions but appreciate his reasoning.
Bob can make these arguments because he's comfortable discussing Linux at the user interface level (GUI or command line), at the network level (protocols, sockets, ports) and at the operating system and programming levels (system calls, C programming, etc.) This reminded me of Radia Perlman's "Interconnections" networking book, where she explains protocols she invented, such as the spanning tree algorithm.
RWLS is not perfect. The "one way credit card data path" proposal needs a diagram. Page 500's says a ".
A poll taken in July 2001 for Network World asked 100 network executives what their biggest technology concerns were in 2001. It turns out that their biggest concern was "making sure the network is hackerproof." I?ll ignore for now the fact that there is no such word as hackerproof; I?ll take license and substitute the term bulletproof, which dictionary.com informally defines as impervious to assault, damage, or failure; guaranteed. With that, can network security and commercial off-the-shelf operating systems ever be impervious to assault, damage, or failure? Not even the largest seller of security snake oil would say yes to such a statement. Information security adversaries are already at the gate, posing legitimate threats; it is not a question of if networks will be attacked, but when. It is within this framework that Bob Toxen presents Real World Linux Security, a superb overview of how to comprehensively secure a Linux system.
Toxen is one of the original developers of Berkeley Unix, and his book is full of interesting historical tidbits from the computer science halls of UC Berkeley in the early 1970s. When it comes to Unix security, Toxen?s mantra is certainly "been there, done that." Toxen is one of a very few writers who can write in the first person about developing operating systems while dropping names such as Bill Joy and Ken Thompson.
Although it comprises nearly 700 pages, Real World Linux Security is light on filler and bursting with important information on how to secure a Linux host. In reference to space filler, other books often have about a third of their content made up of screen prints and source code listing. Toxen's book fortunately does not use that route and instead directs readers to either a Web site or the companion CD-ROM for source code.
