When I began writing this book, the first question I asked myself was how to install Linux on a server, and be sure that no one from the outside, or inside, could access it without authorization. Then I wondered if any method similar to the one on windows exists to improve the computer’s performance. Subsequently, I began a search on the Internet and read several books to get the most information on security and performance for my server. After many years of research and studies I had finally found the answer to my questions. Those answers were found all throughout different documents, books, articles, and Internet.
