Cybersecurity - Attack and Defense Strategies

By: Yuri Diogenes, Dr. Erdal Ozkaya

Overview of this book

The book will start talking about the security posture before moving to Red Team tactics, where you will learn the basic syntax for the Windows and Linux tools that are commonly used to perform the necessary operations. You will also gain hands-on experience of using new Red Team techniques with powerful tools such as python and PowerShell, which will enable you to discover vulnerabilities in your system and how to exploit them. Moving on, you will learn how a system is usually compromised by adversaries, and how they hack user's identity, and the various tools used by the Red Team to find vulnerabilities in a system. In the next section, you will learn about the defense strategies followed by the Blue Team to enhance the overall security of a system. You will also learn about an in-depth strategy to ensure that there are security controls in each network layer, and how you can carry out the recovery process of a compromised system. Finally, you will learn how to create a vulnerability management strategy and the different techniques for manual log analysis.

Securing remote access to the network


No networking segmentation planning would be complete without considering the security aspects of remote access to your corporate network. Even if your company does not have employees that work from home, chances are that at some point, an employee will be traveling and will need remote access to the company's resources. If this is the case, you need to consider not only your segmentation plan, but also a network access control system that can evaluate the remote system prior to allowing access to the company's network; this evaluation includes verifying the following details:

  • That the remote system has the latest patches
  • That the remote system has antivirus enabled
  • That the remote system has a personal firewall enabled
  • That the remote system is compliant with mandate security policies

The following diagram shows an example of a network access control (NAC) system:

In this scenario, the NAC is responsible not only for validating the current health state of...
