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

Clearing tracks and trails


A penetration test consists of a sequence of complex tasks executed against the target. The execution of these tasks impacts the target system in many ways. Several configuration files may get modified, a lot of audit records may get recorded in log files, and there might be changes in the registry in the case of Windows systems. All these changes may help the investigators or blue team members to trace back the attack vector.

After completing a penetration test, it would be good to clear all the residual files that were used during the compromise. However, this needs to be in agreement with the blue team. Another intent behind clearing out all the tracks could be testing the post-incident response methods of an organization. However, the real-world attackers would simply use this to cover their tracks and stay undetected.

 

Metasploit has certain capabilities that help with clearing tracks. First, we need to exploit a vulnerability and give Meterpreter access to...
