While the volume addresses architectural aspects of CORBA Security and provides a healthy discussion of object-specific security issues, it is really about a much more pervasive subject. Namely, how the fundamental tenant of Security Policy design can and should be woven through Identity, Authentication, Privilege, and Access Control. It also tackles two of the most misunderstood, yet critical security issues in modern N-tier distributed systems: Delegation and Non-Repudiation.
The writing style, like the author himself (whom I'm acquainted with on a processional level) is modest, direct, and inclusive. All terminology is progressively defined and clearly communicates the underlying concepts. As a budding security architect and veteran software engineer I highly recommend this book to managers, system designers, security administrators, and members of the legal and causality communities. In short anyone needing a deeper understanding of policy-driven, distributed computer security systems, CORBA or no CORBA.
"CORBA Security" is very much in the classic vein of "The Elements of Style" (E.B. White) - concise, accessible, and durably relevant. A true classic!
Despite the title, this book is not focused on CORBA, but is more a general introduction to the issues of security. In that area, it is a very good book. The basic problems and general solutions to security issues are presented in a manner well within the grasp of non-technical readers.
The three main areas of protection: authorization, accountability and availability are explained in detail, using an example that is both practical and instructive. Submitting a tax return electronically is a serious business and the explanation of how every party to the transaction satisfies these three criteria is the best explanation of the process that I have read.
If your goal is to learn the basics of computer security in the context of, but not exclusive to a CORBA environment, then this book is exactly what you are looking for. If your interest is in a detailed explanation of CORBA, then you must look elsewhere.
In my view, the most important part of the book is its last chapter (i.e., Chapter 10 entitled "Questions to Ask Your Secure Object System Vendor"). Why? Because this chapter outlines thirteen questions that end user organizations can ask their vendors (in this case, Object Request Broker (ORB) vendors and referred to in the book as "secure object system vendors"). These thirteen questions are simple security questions that will get to the bottom line of capabilities of what ORB vendors may or may not supply with their ORB's security service. Thus, it can be used as a buyers guide to the types of security capabilities that your organization may desire with an ORB product.

Michael Todaro writes from a left-of-center perspective and is more ideological than most textbook writers. However, he presents other points of view and presents them pretty fairly in my opinion. And I have to say that he scores some pretty big points against the neoclassical theorists by showing that their assumptions are frequently at odds with reality.
While some of Todaro's more stridently ideological statements can be annoying, I know of no other book that provides such a comprehensive, well organized, and engagingly written introduction to economic development.

That aside, this is a wonderful book. it is not well written, but Hardin never claimed to be a writer. This is the only known autobigraphy by an actual American West gunslinger, and Hardin, according to both himself and history, was one of the greatest.
There seems to be a fair amount of exaggeration and plain old tale telling, but I think you'd find that in any autobiography. This is both an insightful view into a time long gone and an entertaining read. If you've ever watched a western, read one, or just plain pretended you were an outlaw when you were a kid, then you owe it to yourselfd to have a copy of Hardin's book on your shelves.

The good things of this dictionary are very simple, kind and clear.(not too many grammer codes and labels, definitions easy to understand and easy to see editing--> I feel so fresh this editing, my eyes are not tired..!)
Especially the best thing that I think is the USAGE NOTE! For example , "USAGE NOTE- desire, want, and wish- Use WANT to talk about things you would like to do or have....-Use DESIRE and WISH only in very formal writing or in literature:......(X) DON'T SAY-desire to do someting(X)"
Nobody who was my English teachers told me that things.. (of course I respect my English teachers...:) I think this dictionary is best one for foreigner who learns English as a second language like me. If you buy this one, you will NOT regret your choice... Good luck to your English learning.. from KOREA
If you like reading about tough, no non-sense lawmen of the west or historical accounts of Texas Rangers, you will really enjoy this book. This man had character, integrity, and a single-minded focus on upholding the law. He usually worked alone, most times outnumbered and rarely was outwitted by his adversaries.
This should be a required reading for students in Louisiana schools...they should revere and remember the heroes that help build their state.

Pauline Brent, a doctor's receptionist, is found hanging from a yew tree in the local graveyard. A preliminary examination reveals that she may have been strangled and then strung up onto the tree. Not too far from the crime scene, Neil Watson of the County Archaeological Unit has just uncovered the grave of a woman who was buried at the crossroads (an unhallowed grave) about 5 centuries ago. Local legend has it that the woman was publicly hanged from the very same tree that Pauline Brent was discovered in -- it was believed that she had committed a horrific murder. Could Pauline Brent's murder be linked to a 500 year old lynching? D.S. Peterson wonders as he considers the fact that Pauline's murderer must have known of the tree's reputation. This would then make Pauline's death some kind of execution. What wrong could Pauline have committed to merit such a theatrical end? Peterson must discover all he can about Pauline, but she soon proves to be an enigma -- a woman who was well liked but not fully excepted by the villagers because she was an 'incommer', she also seems to have very few friends and practically no history prior to her arrival at the village. It looks as if Pauline Brent was hiding from something, but what and why? In the meantime, Neil Watson tries to discover more about the young woman who was executed 500 years ago, and of the crime for which she was hanged. Tension mounts as both men home in on the backgrounds of the the two women and of the crimes that they allegedly committed.
This novel was truly well crafted: the manner in which Ellis switches seamlessly between the centuries, and the way in which the solution of one mystery points to the solution of the other -- that was brilliant. I was well and truly hooked by "An Unhallowed Grave" and recommend as riveting reading.
Ellis' characters are definitely characters. I love Wesley's boss, a lonely widower who is looking for friends. Part of the ability to draw realistic characters is the ability to observe real human beings and their reactions to normal life, which includes loved ones dying from cancer and the subsequent need of those left behind to find something to do with themselves besides work. If the reader can sympathize with the character, then the author has done a good job.
As always, I enjoy reading British writers and really enjoy reading mysteries with a historical bent. I had no idea about the existence of art called "Jesse Trees" which are an artistic rendering of the geneaology of Jesus. I am so intrigued by this I plan to look up some more information on these 'trees'...

As the mystery unfolds, Wesley discovers Pauline's secret. Now, rather than to few people with motive, there are too many. It turns out that relying on the historical parallels (being dug up by archeologist-buddy Neil) is key to solving the murder.
I enjoyed Ellis's earlier book THE ARMADA BOY but found AN UNHALLOWED GRAVE even better. Ellis writes well--definitely English but with little enough dialect that the novel is approachable by an American audience. Better yet, she doesn't write down to the reader, yet brings a thoughtful approach to both the mystery and the characters.
Somewhere between a cozy and gritty urban mystery, Ellis writes of bucolic but dangerous small-town England. Excellent.
