Introduce web application security and penetration testing with Kali Linux for beginners. Build a hands-on lab to practice testing, vulnerability assessment, and securing web applications.
Explore web application security basics, including common vulnerabilities and W.A.S.P. top 10, server misconfigurations, and secure development, with Kali Linux-based testing and client engagement to improve security posture.
Explore the OWASP top 10 vulnerabilities for web apps. Learn risks such as injection, broken authentication, external entities, and insecure deserialization, plus cross-site scripting, and insufficient logging.
Compare vulnerability assessment and penetration testing, explaining threats, vulnerabilities, and risks, and show how exploitable vulnerabilities drive ethical hacking and risk-based security reporting.
Identify security issues within the contract scope and communicate clearly with the customer to improve the application's security posture. Maintain confidentiality, seek management approval, and fully disclose findings and fixes.
Build a test lab for web app security on a physical PC with 64-bit Windows and 8 GB RAM; install VirtualBox, Kali Linux, and a prepackaged vulnerable web app.
Design and configure a Kali Linux test lab in VirtualBox with a DVWA machine on a host-only network, importing the Kali OVA and DVWA ISO, and ensure connectivity.
Explore the DVWA web interface, access the login page via the DVWA IP 192.168.56.200, create or reset the database, and set security to low for practical attack practice.
Explore brute force, CSRF, and file inclusion attacks by showing how URL parameters can reveal credentials, allow password changes, and expose unauthorized files in a web interface.
Discover how sql injection exploits web applications to access or alter databases, including blind sql injection, and how true statements can reveal user information.
Explore cross-site scripting attacks that inject scripts into web applications with weak input validation, test using an XSS reflector, and understand potential impacts like script execution and session data exposure.
Explore command execution vulnerabilities in web applications, demonstrating how arbitrary shell commands can be run, view sensitive files, and even take full control of a server using netcat.
Leverage the open source OWASP ZAP to perform vulnerability testing on web applications, using a local proxy, running active scans, and reviewing alerts for vulnerabilities.
Configure OWASP ZAP to perform scans using safe, protected, standard, and attack modes. Automate login with form-based authentication, contexts, and forced user mode to discover URLs and identify SQL injection.
Explore Burp Suite, a Java-based graphical tool for web application security testing, featuring proxy, spider, and scanner modules, plus free versus paid versions with traffic interception and crawling.
Learn to use Burp Suite part 2 to perform advanced testing with intruder for brute-force attacks and repeater to modify and inspect HTTP requests, uncovering vulnerable parameters and responses.
Develop secure web applications by performing risk analysis and applying input validation, authentication, authorization, and configuration controls to prevent SQL injection, XSS, and command execution, while securing sessions.
Explore how web application firewalls act as a proxy between users and applications, intercepting traffic to block sql injection, xss, and top attacks using signatures and learning policies.
Install more security, a free Apache web application firewall, configure it with rule sets, activate rules, and switch to blocking to protect your web applications.
A website vulnerability is a weakness or misconfiguration in a website or web application code that allows an attacker to gain some level of control of the site, and possibly the hosting server. Most vulnerabilities are exploited through automated means, such as vulnerability scanners and botnets. There are a lot of common web application vulnerabilities as a result of insecure code development practices or using vulnerable software, some examples are: SQL Injection, Cross Site Scripting (XSS), Command Execution, File Injection, Cross Site Request Forgery (CSRF), etc.
Kali Linux is a Linux distribution that is specialized for cybersecurity. It is an open-source product that involves a lot of customization for penetration testing, which helps companies to understand their vulnerabilities. It is maintained and funded by Offensive Security.
A web application firewall (WAF) protects web applications from a variety of application layer attacks such as cross-site scripting (XSS), SQL injection, and cookie poisoning, among others. Attacks to apps are the leading cause of breaches—they are the gateway to your valuable data.
In this course, you will learn about web application ethical hacking techniques including using some Kali Linux tools:
Introduction to web penetration testing and ethical hacking
Designing and building a lab environment for pen testing
Understanding website vulnerabilities and general attacks
Understanding how to protect your website against attacks
Secure coding and web application firewalls
