Computer viruses and security leaks make the news almost every month. Local area networks are particularly vulnerable, in less than one second, a tiny virus can erase megabytes of data and wipe out weeks of work performed by dozens of people. Now Stephen Cobb has compiled a complete guide to PC and LAN security, covering everything computer users need to guard their systems from today's most common threats. Cobb explains how to protect hardware through multiple means, including alarm and security systems, product registration and insurance, fault tolerance, and more. He covers software protection, discussing encryption systems, passwords, add-ons, alternative power supplies, and back-up strategies. Then, a final section focuses on securing networks against unwanted intruders, with an entire chapter devoted to virus prevention.
