Testing a sample website for vulnerabilities

-

 

1. What is Web Vulnerability Testing? 🌐⚠️

Web vulnerability testing is the process of identifying security weaknesses in a website or web application before attackers can exploit them.
Goal: Ensure website security, prevent data breaches, and maintain trust. ✅

2. Common Web Vulnerabilities 🛡️

  • SQL Injection (SQLi) 🐍 – Attackers manipulate database queries

  • Cross-Site Scripting (XSS) 💻⚡ – Inject malicious scripts into web pages

  • Cross-Site Request Forgery (CSRF) 🔄 – Tricks users into performing unwanted actions

  • Insecure Direct Object References (IDOR) 🔑 – Unauthorized access to resources

  • File Inclusion Vulnerabilities 📂 – Upload or include malicious files

  • Broken Authentication 👤 – Weak passwords, session hijacking

3. Preparation Before Testing 📝

  1. Get permission ⚖️ – Always test websites legally or in a lab environment

  2. Set up a test environment 🖥️ – Use a sample website or staging server

  3. Gather tools 🛠️ – Vulnerability scanners, proxies, browsers, etc.

4. Popular Tools for Web Vulnerability Testing 🛠️

  • OWASP ZAP 🕷️ – Free web app vulnerability scanner

  • Burp Suite 🏗️ – Proxy tool for intercepting and manipulating traffic

  • Nikto 🔎 – Web server vulnerability scanner

  • SQLmap 🐍 – Automated SQL injection testing

  • Nmap 🌐 – For network & port scanning

5. Basic Testing Steps 🔍

1. Reconnaissance 🧐

  • Gather information about the website: domain, server, technologies used

  • Tools: whois, nslookup, nmap

2. Scanning 📡

  • Scan for open ports, services, and exposed endpoints

  • Tools: Nmap, Nikto

3. Vulnerability Identification ⚠️

  • Test for SQLi, XSS, CSRF, file uploads, authentication issues

  • Tools: OWASP ZAP, Burp Suite, SQLmap

4. Exploitation (Safe Testing Only) 🛡️

  • Confirm vulnerabilities exist without harming the system

  • Example: Inject test payloads in a lab environment

5. Reporting 📝

  • Document vulnerabilities found, their impact, and recommended fixes

  • Include screenshots, logs, and suggested remediation

6. Best Practices ✅

  • Always test in authorized environments ⚖️

  • Use non-destructive payloads 🛡️

  • Keep testing systematic & documented 📝

  • Prioritize high-risk vulnerabilities first 🔥

  • Stay updated with OWASP Top 10 🌐

Computers are electronic devices that are designed to process, store, and retrieve data. They are used for a wide variety of purposes, from personal computing to complex scientific simulations and industrial automation. A computer consists of various hardware components, including a central processing unit (CPU), memory, storage devices, input/output (I/O) devices such as keyboards, mice, and displays, and various other peripherals. Computers communicate with each other over networks, which are interconnected groups of computers that share resources and information. The internet is a global network that connects millions of computers around the world and enables communication and information sharing on an unprecedented scale. The field of computer science is concerned with the study of computers and computational systems, including their design, development, and application. It encompasses many subfields, including artificial intelligence, computer graphics, databases, programming lang...

Computer Generation

 There are five generations of computer:  First generation– 1946 - 1958  Second generation– 1959 - 1964  Third generation– 1965 - 1970  Fourth generation– 1971 - today  Fifth generation– Today to future The First Generation   The first computers used vacuum tubes for circuitry and magnetic drums for memory, and were often enormous, taking up entire rooms.  They were very expensive to operate and in addition to using a great deal of electricity, generated a lot of heat, which was often the cause of malfunctions. The Second Generation   Transistors replaced vacuum tubes and ushered in the second generation of computers.  One transistor replaced the equivalent of 40 vacuum tubes.    Allowing computers to become smaller, faster, cheaper, more energy-efficient and more reliable.  Still generated a great deal of heat that can damage the computer. The Third Generation  The development of the integrated circuit was ...
