    Essential reading for e-business and home Internet security

    There may be many good books on computer Security but few are written for the average person. I found Cyber Threat is a light, enjoyable read and packed with the information I realised I needed. The chapters are spiced with real world examples that will hit close to home. Highly recommended to anyone woring or playing on-line.
