WEB APPLICATION SECURITY

What is web application security

Web application security is about protecting websites and online applications from cyber attacks. These attacks can target vulnerabilities in the website’s code or its server, allowing hackers to steal data, disrupt services, or gain unauthorized access. To secure a web application, developers use various tools and practices, such as encryption, firewalls, and regular security updates. The goal is to ensure that users’ information stays safe and the application runs smoothly without being compromised.

Common web application attacks

SQL Injection: This attack involves inserting harmful SQL code into a query to access or manipulate the database. For example, an attacker might gain access to all users’ data by modifying a login form.

Cross-Site Scripting (XSS): In XSS attacks, an attacker injects malicious scripts into a website, which then run in the user’s browser. This can be used to steal user information, like cookies, or to trick the user into taking unwanted actions.

Cross-Site Request Forgery (CSRF): In a CSRF attack, the attacker tricks a user into performing actions they didn’t intend to, like transferring money or changing account details, by exploiting the user’s session with a trusted website.
