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.

Detection capabilities


The current threat landscape demands a new approach to detection systems, relying on the traditional complexity to fine-tuning initial rules, thresholds, baselines and still deal with lots of false positives is becoming unacceptable for many organizations. When preparing to defend against attackers, the Blue Team must leverage a series of techniques that include:

  • Data correlation from multiple data sources
  • Profiling
  • Behavior analytics
  • Anomaly detection
  • Activity evaluation
  • Machine learning

It is important to emphasize that some of the traditional security controls, such as protocol analysis and signature-based antimalware, still have their space in the line of defense, but to combat legacy threats. You shouldn't uninstall your anti-malware software just because it doesn't have machine learning capability, it is still one level of protection to your host. Remember the defense in depth approach that we discussed in the last chapter? Think of this protection as one layer of defense...
