Lesson 3: Vulnerabilities
In this lesson, we will examine the different types of vulnerabilities that attackers exploit to compromise systems, applications, and data. Vulnerabilities can exist in software, hardware, mobile devices, operating systems, cloud platforms, and third-party supply chains, often resulting from weak configurations, coding flaws, or outdated components. Understanding these weaknesses is essential for reducing risk, strengthening defenses, and preventing security incidents.
By the end of this lesson, you should be able to:
- Identify and explain application vulnerabilities such as buffer overflows, injection flaws, and insecure libraries.
- Recognize hardware and mobile device vulnerabilities, including firmware weaknesses, side-channel attacks, jailbreaking, sideloading, and insecure data storage.
- Understand virtualization and operating system vulnerabilities, including VM escape, hypervisor flaws, misconfigurations, and default accounts.
- Describe cloud and web-based vulnerabilities such as insecure APIs, misconfigured storage, XSS, SQL injection, CSRF, and directory traversal.
- Explain supply chain vulnerabilities, including backdoored updates and counterfeit components.
