Hello, Everyone!

I am looking for a good book, Internet resource that can clearly explain these terms. Really, I would not like to read any Microsoft books or any book about windows or other operation systems. I really need the theoretical explanations.

I am appreciated to get any help.

• That should be a good book. It is on information security, and has chapters on system security.

  Gilles : [Rob Slade's review is quite positive](http://victoria.tc.ca/int-grps/books/techrev/bkcmscpp.rvw).

  igor : @skhushalani. +1 any help, welcome!

  Sagar : We had this book for our Information Security class and I remember covering the topics you are talking about. It is probably the only textbook I actually enjoyed reading.

• Look at at Rob Slade's reviews. His reviews are very good, because he doesn't hesitate to point out the defects in a book, and he explains what the book can bring to various audiences.

  An excellent book covering security in general is Ross Anderson's. An older edition is available online. He covers a wide range of topics, so after you've read the relevant chapters, you may want to follow some bibliographic references.

  igor : +1 Thanks, Gilles. It is a good starting point!
