Overview of this book

Cybersecurity – Attack and Defense Strategies, Second Edition is a completely revised new edition of the bestselling book, covering the very latest security threats and defense mechanisms including a detailed overview of Cloud Security Posture Management (CSPM) and an assessment of the current threat landscape, with additional focus on new IoT threats and cryptomining. Cybersecurity starts with the basics that organizations need to know to maintain a secure posture against outside threat and design a robust cybersecurity program. It takes you into the mindset of a Threat Actor to help you better understand the motivation and the steps of performing an actual attack – the Cybersecurity kill chain. You will gain hands-on experience in implementing cybersecurity using new techniques in reconnaissance and chasing a user’s identity that will enable you to discover how a system is compromised, and identify and then exploit the vulnerabilities in your own system. This book also focuses on defense strategies to enhance the security of a system. You will also discover in-depth tools, including Azure Sentinel, to ensure there are security controls in each network layer, and how to carry out the recovery process of a compromised system.

Conclusion and lessons learned

We learned about the two approaches of privilege escalation: horizontal and vertical. Some attackers will use the horizontal privilege escalation methods because they are less taxing. However, veteran hackers who have a good understanding of the systems that they target will use vertical privilege escalation methods. This chapter has gone through some of the specific methods within these two Escalation categories.

It was clear from most methods that hackers had to utilize legitimate processes and services in order to escalate privileges. This is because most systems are built using the least privilege concept, that being that users are purposefully given the least privileges that they require to accomplish their roles. Only the legitimate services and processes are given high-level privileges and, therefore, attackers have to compromise them in most cases.
