This book's concise and consistent approach breaks down security into logical parts, giving actions to take immediately, information on hardening a system from the top down, and finally when to go back and make further upgrades.
Research on Internet security over the past few decades has focused mainly on information assurance, issues of data confidentiality and integrity as explored through cryptograph algorithms, digital signature, authentication code, etc. Unlike other books on network information security, Network Infrastructure Security addresses the emerging concern with better detecting and preventing routers and other network devices from being attacked or compromised. Network Infrastructure Security bridges the gap between the study of the traffic flow of networks and the study of the actual network configuration. This book makes effective use of examples and figures to illustrate network infrastructure attacks from a theoretical point of view. The book includes conceptual examples that show how network attacks can be run, along with appropriate countermeasures and solutions.
This book's concise and consistent approach breaks down security into logical parts, giving actions to take immediately, information on hardening a system from the top down, and finally when to go back and make further upgrades.
Provides insights on maintaining security of computer networks, covering such topics as identity management systems, Web services, mobile devices, data encryption, and security patching.
Plug the gaps in your network’s infrastructure with resilient network security models Key FeaturesDevelop a cost-effective and end-to-end vulnerability management programExplore best practices for vulnerability scanning and risk assessmentUnderstand and implement network enumeration with Nessus and Network Mapper (Nmap)Book Description Digitization drives technology today, which is why it’s so important for organizations to design security mechanisms for their network infrastructures. Analyzing vulnerabilities is one of the best ways to secure your network infrastructure. This Learning Path begins by introducing you to the various concepts of network security assessment, workflows, and architectures. You will learn to employ open source tools to perform both active and passive network scanning and use these results to analyze and design a threat model for network security. With a firm understanding of the basics, you will then explore how to use Nessus and Nmap to scan your network for vulnerabilities and open ports and gain back door entry into a network. As you progress through the chapters, you will gain insights into how to carry out various key scanning tasks, including firewall detection, OS detection, and access management to detect vulnerabilities in your network. By the end of this Learning Path, you will be familiar with the tools you need for network scanning and techniques for vulnerability scanning and network protection. This Learning Path includes content from the following Packt books: Network Scanning Cookbook by Sairam JettyNetwork Vulnerability Assessment by Sagar RahalkarWhat you will learnExplore various standards and frameworks for vulnerability assessments and penetration testingGain insight into vulnerability scoring and reportingDiscover the importance of patching and security hardeningDevelop metrics to measure the success of a vulnerability management programPerform configuration audits for various platforms using NessusWrite custom Nessus and Nmap scripts on your ownInstall and configure Nmap and Nessus in your network infrastructurePerform host discovery to identify network devicesWho this book is for This Learning Path is designed for security analysts, threat analysts, and security professionals responsible for developing a network threat model for an organization. Professionals who want to be part of a vulnerability management team and implement an end-to-end robust vulnerability management program will also find this Learning Path useful.
This Springer Brief examines the tools based on attack graphs that help reveal network hardening threats. Existing tools detail all possible attack paths leading to critical network resources. Though no current tool provides a direct solution to remove the threats, they are a more efficient means of network defense than relying solely on the experience and skills of a human analyst. Key background information on attack graphs and network hardening helps readers understand the complexities of these tools and techniques. A common network hardening technique generates hardening solutions comprised of initially satisfied conditions, thereby making the solution more enforceable. Following a discussion of the complexity issues in this technique, the authors provide an improved technique that considers the dependencies between hardening options and employs a near-optimal approximation algorithm to scale linearly with the size of the inputs. Also included are automated solutions for hardening a network against sophisticated multi-step intrusions. Network Hardening: An Automated Approach to Improving Network Security is a valuable resource for researchers and professionals working in network security. It is also a useful tool for advanced-level students focused on security in computer science and electrical engineering.
