"Gone are the days when computer security was just a big-company problem. Ensuring safe and secure communications, transactions, and data transfer is now an issue for everyone doing business online. This versatile book is a step-by-step guide to solving both the common and the more complex security issues (and protecting your precious information). Thorough, yet practical and plain-spoken, the book is accessible to both novices and computer professionals, and covers every base, including: analyzing and eliminating vulnerabilities and risks; file-sharing issues; virus threats; SPAM; e-mail security; Public Key Infrastructure; digital signatures; "Pretty Good Privacy"; and, hardware and software firewalls. Other key issues include the security risks of different Internet connections, particularly the vulnerability of the new "always-on" broadband technology. Readers also get information on safe Web browsing and "cookie" technology, remote connectivity and wireless Web technology - plus the future of the Internet and online security."
