Introduction Cross-Site Request Forgery (CSRF) is a critical web security vulnerability that exploits the trust a web application has in a user’s browser. By leveraging authenticated sessions, attackers can trick users into performing unintended actions on web applications without their consent. This article delves into the mechanics of CSRF attacks, real-world examples, and effective prevention […]

Introduction Cross-Site Scripting (XSS) is a major web security vulnerability that allows attackers to inject malicious scripts into trusted websites. These scripts execute in the victim’s browser, leading to data theft, session hijacking, phishing, and unauthorized actions. Based on Fogie et al., Chapter 2, this article explores XSS attack types, real-world examples, and effective prevention

Introduction Cross-Site Scripting (XSS) and Cross-Site Request Forgery (CSRF) are two of the most dangerous security vulnerabilities affecting web applications today. Understanding how these attacks work and how to defend against them is critical for developers, security professionals, and web application maintainers. Cross-Site Scripting (XSS) What is XSS? XSS vulnerabilities arise when web applications fail

Introduction Web applications are a primary target for cyberattacks, making penetration testing (pen testing) a crucial security practice. Web application penetration testing involves simulating attacks to identify vulnerabilities and weaknesses in an application before malicious actors can exploit them. This article explores the methodologies, tools, and key testing techniques based on Purewal (2014), OWASP guidelines,

Introduction SQL Injection (SQLi) is a critical cybersecurity threat that allows attackers to manipulate database queries and gain unauthorized access to sensitive data. While basic SQL injection exploits are well-known, attackers use advanced SQL injection strategies to bypass security measures and escalate their attacks. This article explores advanced SQLi techniques based on Galluccio et al.,

Introduction to SQL Injection SQL Injection (SQLi) is a critical cybersecurity vulnerability that allows attackers to manipulate an application’s SQL queries to gain unauthorized access to databases. This flaw occurs when user input is improperly sanitized before being included in SQL statements. If exploited, SQL injection can lead to data breaches, unauthorized modifications, and even

Understanding Databases A database is a structured system for storing, managing, and retrieving data efficiently. It serves as the foundation for modern applications, from websites and mobile apps to enterprise systems. Databases organize information in a structured way, allowing users to access and manipulate data securely. Types of Databases Introduction to SQL (Structured Query Language)

Introduction to Databases A database is a structured collection of data that allows for efficient storage, retrieval, and management of information. Think of it as a digital library where data replaces books, and a database management system (DBMS) acts as the librarian, helping to organize and access information. Databases come in various types, but the

Understanding Web Security Threats In the realm of web security, SQL Injection (SQLi) and Cross-Site Scripting (XSS) are two of the most prevalent and dangerous vulnerabilities. These attacks can lead to unauthorized access, data theft, and even full system compromise. Understanding their mechanisms and mitigation techniques is crucial for developers, security professionals, and ethical hackers.

Introduction Secure software development is essential for mitigating security vulnerabilities and ensuring software resilience against cyber threats. The Software Assurance Forum for Excellence in Code (SAFECode) provides key guidelines for integrating security into the Software Development Lifecycle (SDL). These best practices help organizations build secure software by addressing security risks proactively. This article outlines the
