About this product

Product Information

Once your security is breached, everyone will ask the same question: now what? Answering this question has cost companies hundreds of thousands of dollars in incident response and computer forensics fees. This book reduces the investigative workload of computer security incident response teams (CSIRT) by posturing organizations for incident response success. Firewalls can fail. Intrusion-detection systems can be bypassed. Network monitors can be overloaded. These are the alarming but true facts about network security. In fact, too often, security administrators' tools can serve as gateways into the very networks they are defending. Now, a novel approach to network monitoring seeks to overcome these limitations by providing dynamic information about the vulnerability of all parts of a network. Called network security monitoring (NSM), it draws on a combination of auditing, vulnerability assessment, intrusion detection and prevention, and incident response for the most comprehensive approach to network security yet. By focusing on case studies and the application of opensource tools, the author helps readers gain hands-on knowledge of how to better defend networks and how to mitigate damage from security incidents.
