Understanding the danger landscape is crucial for defense. In this chapter, we'll survey the most common forms of application vulnerabilities and episodes seen in typically the wild today. You will discuss how that they work, provide practical types of their écrasement, and introduce greatest practices to avoid all of them. This will lay the groundwork for later chapters, which will delve deeper straight into how to build security into the development lifecycle and specific defense. Over the yrs, certain categories regarding vulnerabilities have come about as perennial problems, regularly appearing inside security assessments plus breach reports. Market resources such as the OWASP Top 10 (for web applications) and even CWE Top 25 (common weaknesses enumeration) list these typical suspects. Let's discover some of typically the major ones: ## Injection Attacks (SQL, Command Injection, etc. ) - **Description**: Injection flaws take place when an app takes untrusted type (often from the user) and feeds it into the interpreter or control in a way that alters typically the intended execution. Typically the classic example is definitely SQL Injection (SQLi) – where end user input is concatenated into an SQL query without correct sanitization, allowing you put in their own SQL commands. Similarly, Order Injection involves treating OS commands, LDAP Injection into LDAP queries, NoSQL Injections in NoSQL directories, and so on. Essentially, the application fails to distinguish data from code recommendations. - **How that works**: Consider a simple login kind that takes a good account information. If the server-side code naively constructs a question such as: `SELECT * THROUGH users WHERE logi
