If you re a security or network professional, you already know the do s and don ts: run AV software and firewalls, lock down your systems, use encryption, watch network traffic, follow best practices, hire expensive consultants . . . but it isn t working. You re at greater risk than ever, and even the world s most security-focused organizations are being victimized by massive attacks. In ' Thinking Security, ' author Steven M. Bellovin provides a new way to think about security. As one of the world s most respected security experts, Bellovin helps you gain new clarity about what you re doing and why you re doing it. He helps you understand security as a systems problem, including the role of the all-important human element, and shows you how to match your countermeasures to actual threats. You ll learn how to move beyond last year s checklists at a time when technology is changing so rapidly. You ll also understand how to design security architectures that don t just prevent attacks wherever possible, but also deal with the consequences of failures. And, within the context of your coherent architecture, you ll learn how to decide when to invest in a new security product and when not to. Bellovin, co-author of the best-selling Firewalls and Internet Security, caught his first hackers in 1971. Drawing on his deep experience, he shares actionable, up-to-date guidance on issues ranging from SSO and federated authentication to BYOD, virtualization, and cloud security. Perfect security is impossible. Nevertheless, it s possible to build and operate security systems far more effectively. ' Thinking Security ' will help you do just that.'
