This wide-ranging, up-to-date, conversational guide to network security focuses on the most important success factors: process and mindset. Security expert Thomas Wadlow shows exactly what it means to be a successful network security manager within a large business organization. Learn how to define what an organization's security goals ought to be -- and how to implement an effective security policy quickly, without endless committee meetings or company politics. Understand who may be attacking you, and how to think pathologically about your network, putting yourself in the shoes of your attacker. Evaluate which information resources are most worth protecting; learn how to build an effective security team; and discover how to build security systems that protect the enterprise as a whole, not just individual devices. Learn how to fortify your network components and design; monitor and audit your network; even quantify the value of security. The book also presents five exceptionally detailed chapters on how to respond effectively to an attack -- from forensics and log analysis to damage control. For every manager and executive concerned with network security, including sysadmins, netadmins, security managers, CIOs, CFOs, and CEOs.
