دانلود کتاب امنیت سایبری – راهنمای کامل تهدیدات و حفاظت سایبری

While conducting my research for this (and the first edition of this) book, I have noted literally hundreds of cyber security incidents – some relatively trivial, some rather more serious. What has never ceased to amaze me is not that they keep happening, but that the same kinds of incident keep happening, and that some people do not appear to learn the lessons of others’ mistakes and occasionally even of their own. In the 21st century, we are almost totally reliant upon information technology, and in particular the interconnectedness that allows us to conduct our lives more efficiently. We now regard access to the connected world as a basic utility along with gas, electricity and water. As business, commerce and government continue to place their services online, we have become increasingly dependent upon something that few people truly understand, and to which some for whatever reason are denied access.
