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

Auditing and logging


Checking for the completeness of application audit logs is one of the most important procedural aspects of application security assessment. Audit logs are categorized as detective controls which come handy in the case of a security incident. An enterprise application is typically complex in nature and interconnected with several other systems such as a database server, load balancer, caching server and many more. In the case of a breach, audit logs play the most important role in reconstructing the incident scenario. Audit logs with insufficient details would limit the incident investigation to a greater extent. So the capability of an application to generate event logs must be carefully examined to find any shortcomings as applicable.

OWASP mapping

Auditing and logging-related vulnerabilities are part of the OWASP Top 10 2017. They are covered under A10:2017 Insufficient Logging and Monitoring. Some of the vulnerabilities listed under this category are as follows:
