As organizations continue to add more technology into their environment to support the growing demand of their workforce and meet their business objectives, they’re also increasing their attack surface from a cybersecurity perspective. While many companies have either an internal Information Technology (IT) unit or are outsourcing their technical services to a thirdparty provider, these teams are responsible for configuring systems and network architectures. However, quite often IT professionals may not always apply best practices such as using secure baselines or ensuring systems have the latest firmware or patch installed. Such malpractices create security vulnerabilities that enable threat actors to exploit those flaws and compromise the confidentiality, integrity, and/or availability of the system or network. Therefore, organizations can implement a proactive approach by performing regular security assessments on their assets and network architecture to determine the risk if a real cyberattack or threat were to materialize. Security assessments help organizations identify gaps in their security architecture, determine whether their existing security controls are configured and operating correctly to prevent or mitigate various cyber-attacks. Additionally, security assessments help senior management such as the executive team to better understand the type and severity of cyber-risks that exists and the potential impact to their business if a real threat were to occur. Hence, the need for ethical hacking remains essential as organizations continue to use technology to enhance their operations. Ethical hackers use their skillset to legally help organizations identify hidden security vulnerabilities in their systems and provide recommendations on how to improve their security posture. Yet, there are many organizations that are developing new solutions, expanding their network architectures and implementing new devices but aren’t performing regular ethical hacking assessments to determine whether they are introducing new vulnerabilities within their network or not. Spending over a decade as an information security professional in various industries, I’ve seen many organizations implement various systems, from servers and networking devices to even network security solutions, with misconfigurations and running outdated firmware. As a cybersecurity educator, I’ve met and taught many aspiring and seasoned IT professionals who often admit their oversight of the need for ethical hacking and understanding how this skillset can help them improve their cyber defenses. Furthermore, meeting with many business leaders and having insightful discussions on how their infrastructure can be compromised helps them to better appreciate the proactive approach and need for security assessments and ethical hackers on their technical teams. I’ve written this book to help IT professionals who are interested in ethical hacking and simulating real-world cyber-attacks and threats to identify hidden security vulnerabilities on systems and networks. It builds practical ethical hacking skills through realistic attack scenarios that reflect how security assessments are performed in real organizations. It helps learners move beyond theory by showing how vulnerabilities are discovered, exploited responsibly, and reported clearly. This book begins by introducing the fundamentals of information security such as the importance of protecting confidentiality, integrity, and availability of assets. It explores how ethical hackers adopt common attack frameworks that are mapped to the Tactics, Techniques and Procedures (TTPs) of real adversaries. Using these TTPs helps ethical hackers simulate similar attacks and threats on organizations to determine whether security vulnerabilities exist and better understand their security posture. Then, we take a deep dive into both passive and active reconnaissance techniques and learn how ethical hackers use common tools to assist with collecting and analyzing sensitive information about their targets. You will explore common scanning techniques to identify misconfigurations, vulnerabilities in running services, open ports, and operating system versions of live hosts on a network. Furthermore, you will be delving into vulnerability management to understand how ethical hackers perform vulnerability assessments on targeted systems and networks while using common vulnerability scanners in the industry. The information collected during vulnerability assessment phases helps ethical hackers move to the system hacking phase. During the system hacking phase, you will discover how common tools and techniques enable you to exploit discovered security vulnerabilities, gain unauthorized access, set up, and establish persistent access on compromised devices and networks. You will explore the fundamentals of malware threats and how threat actors use evasion techniques to bypass security controls, and intercept communication channels to capture sensitive information that leads to unauthorized access to systems and networks. The last part of the book explores the security vulnerabilities that exist within wireless networks and how ethical hackers can determine whether their organization is susceptible and apply recommended countermeasures. Lastly, this book concludes by providing you with a structural framework for writing a security assessment report that contains your findings during each phase of your ethical hacking engagement.
