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

Social engineering using SET


In the very first section of this chapter we saw two possible scenarios of exploitation. Either the attacker has direct access to the target system or the target system is behind the router/firewall and the attacker can reach only till the public interface of router/firewall.

In the case of the second scenario, the attacker has to send some kind of payload to the victim and trick him into executing the payload. Once executed, it will establish a reverse connection back to the attacker. This is a covert technique and involves the use of social engineering.

Kali Linux offers an excellent framework for performing various social engineering attacks. The social engineering toolkit can be accessed at Applications | Exploitation Tools | SET.

The initial screen of SET gives various options related to social engineering attacks as shown in the following image:

We select option 1) Social-Engineering Attacks and then we are presented with an array of attacks as shown in the...
