Securing Network Infrastructure

By: Sairam Jetty, Sagar Rahalkar

Overview of this book

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 Jetty •Network Vulnerability Assessment by Sagar Rahalkar

Metrics


An organization may have a very robust vulnerability management program in place. However, there has to be some way by which the progress, success, or failure of the program can be measured. This is when metrics come in handy. Metrics are the key indicators of performance of the vulnerability management program. The organization leadership can take key decisions on strategy and budgeting based on the metrics. Metrics also help to showcase the overall security posture of the organization and raise an alarm for issues that need to be addressed as a priority.

Metrics can be derived based on the various compliance standards or can be completely customized based on the specific organizational needs. The section ahead describes a few such metrics and their relevance. These metrics can be reported at a frequency as per the organizational policy. These metrics can be best represented when shown using various charts, such as bar graphs, pie charts, line graphs, and so on.
