Introduction to ethical hacking
What is penetration testing?
Penetration testing, or pen testing, is the process of attacking an enterprise's network to find any vulnerabilities that could be present to be patched. Ethical hackers and security experts carry out these tests to find any weak spots in a system’s security before hackers with malicious intent find them and exploit them. Someone who has no previous knowledge of the system's security usually performs these tests, making it easier to find vulnerabilities that the development team may have overlooked. You can perform penetration testing using manual or automated technologies to compromise servers, web applications, wireless networks, network devices, mobile devices, and other exposure points.
FAQ regarding Ethical Hacking on Udemy:
What are the different stages of penetration testing?
Penetration tests have five different stages. The first stage defines the goals and scope of the test and the testing methods that will be used. Security experts will also gather intelligence on the company's system to better understand the target. The second stage of a pen test is scanning the target application or network to determine how they will respond to an attack. You can do this through a static analysis of application code and dynamic scans of running applications and networks. The third stage is the attack phase, when possible vulnerabilities discovered in the last stage are attacked with various hacking methods. In the fourth stage of a penetration test, the tester attempts to maintain access to the system to steal any sensitive data or damaging systems. The fifth and final stage of a pen test is the reporting phase, when testers compile the test results.

How to install win7 on Vmware?
Alternatively, you can type, "VMware" in the instant search field and select VMware Workstation from the list of programs (Figure 1). Next, click File | New | Virtual Machine. A wizard appears to create a new virtual machine as shown in Figure 2. Click "Next" and choose how you want to load Windows 7.
Here is the brief tutorial on installing Windows 8 on VMware Workstation. It is better to install Windows 8 virtually before installing on the PC. Any way this is only developer preview not retail version, so install on VMware Workstation and try the features virtuall
Before proceeding with the installation steps, you need to install the VMware virtualization program on your computer. After installation, download the XP ISO file to your host computer by clicking the button below and create a new VM by following the steps below.
VMware is a program vendor for cloud computing and virtualization. They utilize virtualization technology in which a hypervisor is installed on the physical server, allowing the operation of numerous virtual machines (VMs) on the same physical server.
When you install Workstation Pro on a Windows or Linux host system, a NAT network (VMnet8) is set up for you. When you use the New Virtual Machine wizard to create a typical virtual machine, the wizard configures the virtual machine to use the default NAT network.
With NAT, a virtual machine does not have its own IP address on the external network. Instead, a separate private network is set up on the host system. In the default configuration, virtual machines get an address on this private network from the virtual DHCP server.
Penetration testing skills make you a more marketable IT tech. Understanding how to exploit servers, networks, and applications means that you will also be able to better prevent malicious exploitation. From website and network hacking, to pen testing in Python and Metasploit, Udemy has a course for you.
A penetration test, also known as a pen test, is a simulated cyber attack against your computer system to check for exploitable vulnerabilities. In the context of web application security, penetration testing is commonly used to augment a web application firewall (WAF).
What are the types of penetration tests?
An information security audit is an audit on the level of information security in an organization. Within the broad scope of auditing information security there are multiple types of audits, multiple objectives for different audits, etc.
I was an absolute novice when it came to anything related to penetration testing and cybersecurity. After taking this course for over a month, I'm much more familiar and comfortable with the terms and techniques and plan to use them soon in bug bounties.
What is vulnerability scanning?
threat vs. vulnerability. In a nutshell, risk is the potential for loss, damage or destruction of assets or data caused by a cyber threat. Threat is a process that magnifies the likelihood of a negative event, such as the exploit of a vulnerability.
The penetration tester will most likely use automated penetration test tools to scan for initial vulnerabilities. Static analysis and dynamic analysis are two types of approaches used by the penetration tester. Static analysis inspects an application's code in an attempt to predict how it will react to an incursion.

Ethical hacking involves a hacker agreeing with an organization or individual who authorizes the hacker to levy cyber attacks on a system or network to expose potential vulnerabilities. An ethical hacker is also sometimes referred to as a white hat hacker. Many depend on ethical hackers to identify weaknesses in their networks, endpoints, devices, or applications. The hacker informs their client as to when they will be attacking the system, as well as the scope of the attack. An ethical hacker operates within the confines of their agreement with their client. They cannot work to discover vulnerabilities and then demand payment to fix them. This is what gray hat hackers do. Ethical hackers are also different from black hat hackers, who hack to harm others or benefit themselves without permission.

There are many types of penetration testing. Internal penetration testing tests an enterprise's internal network. This test can determine how much damage can be caused by an employee. An external penetration test targets a company's externally facing technology like their website or their network. Companies use these tests to determine how an anonymous hacker can attack a system. In a covert penetration test, also known as a double-blind penetration test, few people in the company will know that a pen test is occurring, including any security professional. This type of test will test not only systems but a company's response to an active attack. With a closed-box penetration test, a hacker may know nothing about the enterprise under attack other than its name. In an open-box test, the hacker will receive some information about a company's security to aid them in the attack.

The IPv4 address is a 32-bit number that uniquely identifies a network interface on a system, as explained in How IP Addresses Apply to Network Interfaces in ethical hacking .
An Internet Protocol version 4 packet header (IPv4 packet header) contains application information, including usage and source/destination addresses for ethical hackers.
A classful network is a network addressing architecture used in the Internet from 1981 until the introduction of Classless Inter-Domain Routing in 1993.
For IPv4, a network may also be characterized by its subnet mask or netmask, which is the bitmask that when applied by a bitwise AND operation to any IP address in the network, yields the routing prefix. Subnet masks are also expressed in dot-decimal notation like an address.
To understand subnetting, you should first understand the decimal and binary structure of an IP address. An IPv4 address is a 32-bit number.
IPv4 address exhaustion is the depletion of the pool of unallocated IPv4 addresses in web hacking .
In IP networking, a private network is a computer network that uses private IP address space.

Network address translation (NAT) is a method of mapping an IP address space into another by modifying network address information in the IP header of packets while they are in transit across a traffic routing device.
An IPv6 packet is the smallest message entity exchanged using Internet Protocol version 6 (IPv6). Packets consist of control information for addressing and routing and a payload of user data. The control information in IPv6 packets is subdivided into a mandatory fixed header and optional extension headers.
DHCP works at the application layer to dynamically assign the IP address to the client and this happens through the exchange of a series of messages called DHCP transactions or DHCP conversation.
The Internet Control Message Protocol (ICMP) is a supporting protocol in the Internet protocol suite.

TCP wraps each data packet with a header containing 10 mandatory fields totaling 20 bytes (or octets). Each header holds information about the connection and the current data being sent. The 10 TCP header fields are as follows: Source port – The sending device's port. Destination port – The receiving device's port.
Comparison of UDP and TCP — In computer networking, the User Datagram Protocol (UDP) is one of the core members of the Internet protocol suite.
Application layer is where the actual communication is initiated and reflects. Because this layer is on the top of the layer stack, it does not serve any other layers. Application layer takes the help of Transport and all layers below it to communicate or transfer its data to the remote host.

By default, Nmap only performs heavy probing such as port scans, version detection, or OS detection against hosts that are found to be up.
To change this behavior, we use option -Pn (no ping option). With this option, nmap continues to perform its function, as if the host is active.

In computer networking, a port is a communication endpoint. At the software level, within an operating system, a port is a logical construct that identifies a specific process or a type of network service in ethical hacking, hacking , penetration testing , bug bounty , hack , cyber security , kali linux , android hacking
A stealth scan is a type of network scanning technique that allows an attacker to remain undetected as it never completes the TCP connection. This type of scan (SYN) is the default when using the -sS option in Nmap port scanner.
In computer networking, a port is a communication endpoint. At the software level, within an operating system, a port is a logical construct that identifies a specific process or a type of network service in nmap.
TCP scan is one of the most popular techniques used in port scanning tasks. It uses the first half of the three-way handshake, which leads to faster network port exploration times as the handshake is never completed in NMAP .
While TCP scans are the most common types of port scans in nmap , ignoring the UDP protocol is a common mistake made by security researchers, one that can offer sensitive information through exposed network services, which can be likewise as exploited as the TCP services.
The Nmap version scanning subsystem obtains all of this data by connecting to open ports and interrogating them for further information using probes that the specific services understand.
One of Nmap's best-known features is remote OS detection using TCP/IP stack fingerprinting. Nmap sends a series of TCP and UDP packets to the remote host and examines practically every bit in the responses. After performing dozens of tests such as TCP ISN sampling, TCP options support and ordering, IP ID sampling, and the initial window size check, Nmap compares the results to its nmap-os-db database of more than 2,600 known OS fingerprints and prints out the OS details if there is a match.
Output files may also be used to resume aborted scans. Nmap makes output available in five different formats.
The Nmap Scripting Engine (NSE) is one of Nmap's most powerful and flexible features. It allows users to write (and share) simple scripts to automate a wide variety of networking tasks. Those scripts are then executed in parallel with the speed and efficiency you expect from Nmap. Users can rely on the growing and diverse set of scripts distributed with Nmap, or write their own to meet custom needs.

Occasionally people suggest that Nmap should not offer features for evading firewall rules or sneaking past IDSs. They argue that these features are just as likely to be misused by attackers as used by administrators to enhance security. The problem with this logic is that these methods would still be used by attackers, who would just find other tools or patch the functionality into Nmap. Meanwhile, administrators would find it that much harder to do their jobs. Deploying only modern, patched FTP servers is a far more powerful defense than trying to prevent the distribution of tools implementing the FTP bounce attack.
So Nmap offers a simpler approach, with six timing templates. You can specify them with the -T option and their number (0–5) or their name.
While Nmap attempts to produce accurate results, keep in mind that all of its insights are based on packets returned by the target machines (or firewalls in front of them). Such hosts may be untrustworthy and send responses intended to confuse or mislead Nmap. Much more common are non-RFC-compliant hosts that do not respond as they should to Nmap probes. FIN, NULL, and Xmas scans are particularly susceptible to this problem.
In Idle Scan, the Zombie computer -as the name implies- has to be an “idle” host which cannot be found so easy sometimes.nmap

Welcome to the "Penetration Testing and Ethical Hacking Complete Hands-on" course
The full path from first scan to finished report: networking, scanning, exploitation, post-exploitation, password cracking, OSINT, web app hacking, social engineering, and Layer 2 attacks, all in one course.
Most ethical hacking courses cover one piece of a penetration test. This one covers the whole thing. You start before the first scan, with the theory of what a penetration test is, and you finish auditing network devices after you've already attacked them, with every major stage of a real engagement in between.
You build your lab first, with Kali Linux, Metasploitable, OWASP Broken Web Applications, BeeBox, and Windows targets. Then you work through the full path: penetration testing fundamentals and legal boundaries, networking from Layer 2 to Layer 7, passive and active network scanning with Nmap, vulnerability scanning with Nessus, exploitation and post-exploitation with Metasploit and Meterpreter, password cracking, OSINT and information gathering, a bug bounty primer, full web application penetration testing (XSS, SQL injection, authentication and session attacks), social engineering and phishing with custom malware, and finally Layer 2 and Layer 3 attacks against real Cisco topologies you build in GNS3.
Whether you're starting from zero and want one course that takes you all the way through, or you've taken pieces of this elsewhere and want them connected into a single, coherent path, this course is built for that. You don't need previous penetration testing experience. Enroll today and begin with lesson one.
What Skills Will You Learn in This Course?
Lab and Penetration Testing Fundamentals: Build a full lab, and learn penetration test types, phases, approaches, and the legal boundaries around them.
Networking from the Ground Up: The OSI and TCP/IP models, Layer 2 through Layer 7, IPv4/IPv6 addressing, subnetting, NAT, DHCP, and the core protocols.
Scanning and Vulnerability Discovery: Passive and active network scanning, Nmap in full depth, and vulnerability scanning and reporting with Nessus.
Exploitation and Post-Exploitation: Exploiting targets with the Metasploit Framework and Meterpreter, Pass the Hash, persistence, and Meterpreter's post-exploitation extensions.
Password Cracking and OSINT: Cracking Windows and Linux password hashes with Hydra, Cain & Abel, and John the Ripper, and gathering intelligence with Shodan, FOCA, theHarvester, and Maltego.
Web Application Penetration Testing: XSS, SQL injection, authentication, authorization, session management, and CSRF, with Burp Suite and ZAP, plus an introduction to bug bounty.
Social Engineering and Malware: Creating and embedding custom malware with MSFVenom, Veil, and TheFatRat, and running phishing campaigns with Empire and the Social Engineering Toolkit.
Network Layer and Device Attacks: Building real Cisco topologies in GNS3, then running MAC flooding, ARP spoofing, DHCP starvation, VLAN hopping, and auditing network devices for weak passwords and SNMP exposure.
Who Is This Course For?
Complete Beginners to Ethical Hacking: Learners who want one course that goes from zero to a full penetration testing skill set, without piecing it together from several courses.
Aspiring Penetration Testers: People preparing for a penetration testing role who want every stage of an engagement covered in order.
Students Who've Taken Pieces Elsewhere: Learners who know some of these tools already and want them connected into one complete, structured path.
Security Analysts and IT Professionals: People who want to understand the full attacker path, from reconnaissance to post-exploitation, to defend against it better.
Bug Bounty Beginners: Learners who want web application and OSINT skills covered thoroughly before they start hunting.
Career Changers into Cybersecurity: People who want a single, comprehensive, hands-on course to build a foundation from.
You don't need previous penetration testing experience. You do need a computer that can run virtual machines. The course starts with networking and lab fundamentals, so even a complete beginner can follow it through to the advanced sections.
Why Learn Complete Penetration Testing?
A penetration test isn't one skill, it's a sequence: understand the network, find what's exposed, exploit it, keep access, gather what matters, and report it so it gets fixed. Learning each stage in isolation leaves gaps at exactly the points where they connect. This course is built around that full sequence, not around any single tool.
These skills apply directly to penetration tester, red team, and security analyst roles, where you're expected to understand the whole engagement, not just the tool you're most comfortable with. Networking fundamentals, exploitation, and reporting judgment are the skills that outlast any specific tool version.
Why Choose This Course?
One course, the whole engagement. Networking, scanning, exploitation, post-exploitation, password cracking, OSINT, web app hacking, social engineering, and network layer attacks, in the order a real penetration test actually runs.
Nothing skipped for time. At close to 20 hours, each stage gets real depth, not a summary, including full sections on Metasploit's post-exploitation extensions and Layer 2 attacks that shorter courses leave out.
Built on real infrastructure. You build real Cisco switch and router topologies in GNS3 and attack them, not just pre-scripted targets.
Web application hacking included in full. XSS, SQL injection, authentication, session, and CSRF attacks are covered as thoroughly as a dedicated web hacking course.
A logical build, not a tool list. Each section assumes what came before it, so exploitation makes more sense because you've already scanned, and post-exploitation makes more sense because you've already exploited.
Free tools only. Every tool in this course is free, so you don't need to buy anything to follow along.
Frequently Asked Questions
Is this course enough on its own, or do I need other courses too?
This course is built to be complete on its own. It covers networking fundamentals, scanning, exploitation, post-exploitation, password cracking, OSINT, web application hacking, social engineering, and network layer attacks in one structured path.
Do I need previous experience with Nmap, Metasploit, or Burp Suite?
No. The course introduces each tool before using it and builds from networking fundamentals upward, so no prior experience with any of these tools is required.
Does the course cover web application penetration testing in depth?
Yes. A full section covers XSS, SQL injection, authentication and authorization flaws, session management, and CSRF, using Burp Suite and ZAP.
Does the course cover network layer and Layer 2 attacks?
Yes. You build real network topologies in GNS3 and run MAC flooding, ARP spoofing, DHCP starvation, and VLAN hopping, then audit the devices for weak passwords and SNMP exposure.
What's the difference between this course and a single-topic course like Nmap or Metasploit?
A single-topic course goes deep on one tool or technique. This course covers the full sequence of a penetration test, so you see how scanning, exploitation, and reporting connect, with meaningful depth at each stage.
How long is the course?
Close to 20 hours of video, organized into the stages of a full penetration testing engagement.
Do I need to buy any tools?
No. Every tool used in this course, including Nmap, Nessus, Metasploit, Burp Suite, and the OSINT and password cracking tools, is free.
Is it legal to practice these techniques?
Practicing on your own lab or on systems you're authorized to test is legal. Using these techniques against systems you don't own or have permission to test is not. This course is built entirely around a lab you set up yourself.
