From website and network hacking, to pen testing in Python and Metasploit, Udemy has a course for you.
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 is Ethical Hacking and what is it used for ?
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.
FAQ regarding Penetration Testing on Udemy:
What are the different types of penetration testing?
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.
A bug bounty program, also called a vulnerability rewards program (VRP), is a crowdsourcing initiative that rewards individuals for discovering and reporting software bugs.
Setting up the laboratory in ethical hacking
Is Ethical Hacking a good career?
Yes, ethical hacking is a good career because it is one of the best ways to test a network. An ethical hacker tries to locate vulnerabilities in the network by testing different hacking techniques on them. In many situations, a network seems impenetrable only because it hasn’t succumbed to an attack in years. However, this could be because black hat hackers are using the wrong kinds of methods. An ethical hacker can show a company how they may be vulnerable by levying a new type of attack that no one has ever tried before. When they successfully penetrate the system, the organization can then set up defenses to protect against this kind of penetration. This unique security opportunity makes the skills of an ethical hacker desirable for organizations that want to ensure their systems are well-defended against cybercriminals.

Why do hackers use Linux?
Many hackers use the Linux operating system (OS) because Linux is a free and open-source OS, meaning that anyone can modify it. It’s easy to access and customize all parts of Linux, which allows a hacker more control over manipulating the OS. Linux also features a well-integrated command-line interface, giving users a more precise level of control than many other systems offer. While Linux is considered more secure than many other systems, some hackers can modify existing Linux security distributions to use them as hacking software. Most ethical hackers prefer Linux because it's considered more secure than other operating systems and does not generally require the use of third-party antivirus software. Ethical hackers must be well-versed in Linux to identify loopholes and combat malicious hackers, as it’s one of the most popular systems for web servers.

What is the Certified Information Security Manager ( CISM ) exam?
Passing the Certified Information Security Manager (CISM) exam indicates that the credentialed individual is an expert in the governance of information security, developing security programs and managing them, as well as managing incidents and risk. For someone to be considered “certified,” they must have passed the exam within the last five years, as well as work full-time in a related career, such as information security and IT administration. The exam tests individuals’ knowledge regarding the risks facing different systems, how to develop programs to assess and mitigate these risks, and how to ensure an organization's information systems conform to internal and regulatory policies. The exam also assesses how a person can use tools to help an organization recover from a successful attack.

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.

Whereas TheHarvester is a script which quickly does something, Recon-ng builds its own database and has many more modules, it even comes with a nice CLI to query the database and/or script actions to do on each item in different tables of the database.
When it comes to getting a clear information gathering concept, the simplest way to define it would be the process of collecting information about something you are interested in.
For those in the cybersecurity industry, this is the first step to take during the earlier stages of any hacking activity (both cracking and ethical hacking), when any black- or white-hat researcher needs to gain as much information as possible about the desired target.
While it’s a fun activity for some researchers, information gathering is also one of the most time-consuming tasks during the intel-recon process, and that is why time management is so important.

In computer networking, ARP spoofing, ARP cache poisoning, or ARP poison routing, is a technique by which an attacker sends (spoofed) Address Resolution Protocol (ARP) messages onto a local area network.
ARP Cache Poisoning with Ettercap
ARP poisoning methods can go undetected on a network if proper detection methods are not in place. Network administrators are usually aware that sniffing is possible on network segments that are connected via network hubs but not all administrators know that there are tools freely available that allow attackers to sniff on switched networks as well
Nmap ("Network Mapper") is a free and open-source (license) utility for network discovery and security auditing.
Whether you want to get your first job in IT security, become a white hat hacker, or prepare to check the security of your own home network, Udemy offers practical and accessible ethical hacking
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.

Becoming an ethical hacker involves learning at least one programming language and having a working knowledge of other common languages like Python, SQL, C++, and C. Ethical hackers must have strong problem-solving skills and the ability to think critically to come up with and test new solutions for securing systems. Ethical hackers should also understand how to use reverse engineering to uncover specifications and check a system for vulnerabilities by analyzing its code.

Ethical hacking is a good career because it is one of the best ways to test a network. An ethical hacker tries to locate vulnerabilities in the network by testing different hacking techniques on them. In many situations, a network seems impenetrable only because it hasn’t succumbed to an attack in years. However, this could be because black hat hackers are using the wrong kinds of methods. An ethical hacker can show a company how they may be vulnerable by levying a new type of attack that no one has ever tried before. When they successfully penetrate the system, the organization can then set up defenses to protect against this kind of penetration. This unique security opportunity makes the skills of an ethical hacker desirable for organizations that want to ensure their systems are well-defended against cybercriminals.
In addition to proficiency in basic computer skills and use of the command line, ethical hackers must also develop technical skills related to programming, database management systems (DBMS), use of the Linux operating system (OS), cryptography, creation and management of web applications and computer networks like DHCP, NAT, and Subnetting. Becoming an ethical hacker involves learning at least one programming language and having a working knowledge of other common languages like Python, SQL, C++, and C. Ethical hackers must have strong problem-solving skills and the ability to think critically to come up with and test new solutions for securing systems. Ethical hackers should also understand how to use reverse engineering to uncover specifications and check a system for vulnerabilities by analyzing its code.

Ethical hacking is legal because the hacker has full, expressed permission to test the vulnerabilities of a system. An ethical hacker operates within constraints stipulated by the person or organization for which they work, and this agreement makes for a legal arrangement. An ethical hacker is like someone who handles quality control for a car manufacturer. They may have to try to break certain components of the vehicle such as the windshield, suspension system, transmission, or engine to see where they are weak or how they can improve them. With ethical hacking, the hacker is trying to “break” the system to ascertain how it can be less vulnerable to cyberattacks. However, if an ethical hacker attacks an area of a network or computer without getting expressed permission from the owner, they could be considered a gray hat hacker, violating ethical hacking principles.

Open-source intelligence (OSINT) is a multi-factor (qualitative, quantitative) methodology for collecting, analyzing and making decisions about data accessible in publicly available sources to be used in an intelligence context. In the intelligence community, the term "open" refers to overt, publicly available sources (as opposed to covert or clandestine sources). OSINT under one name or another has been around for hundreds of years. With the advent of instant communications and rapid information transfer, a great deal of actionable and predictive intelligence can now be obtained from public, unclassified sources. It is not related to open-source software or collective intelligence.

Windows password hashes are stored in the SAM file; however, they are encrypted with the system boot key, which is stored in the SYSTEM file. If a hacker can access both of these files (stored in C:WindowsSystem32Config), then the SYSTEM file can be used to decrypt the password hashes stored in the SAM file.
Many hackers use the Linux operating system (OS) because Linux is a free and open-source OS, meaning that anyone can modify it. It’s easy to access and customize all parts of Linux, which allows a hacker more control over manipulating the OS. Linux also features a well-integrated command-line interface, giving users a more precise level of control than many other systems offer. While Linux is considered more secure than many other systems, some hackers can modify existing Linux security distributions to use them as hacking software. Most ethical hackers prefer Linux because it's considered more secure than other operating systems and does not generally require the use of third-party antivirus software. Ethical hackers must be well-versed in Linux to identify loopholes and combat malicious hackers, as it’s one of the most popular systems for web servers.

FAQ regarding Ethical Hacking on Udemy:
What is Ethical Hacking and what is it used for ?
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
Is Ethical Hacking a good career?
Yes, ethical hacking is a good career because it is one of the best ways to test a network An ethical hacker tries to locate vulnerabilities in the network by testing different hacking techniques on them In many situations, a network seems impenetrable only because it hasn’t succumbed to an attack in years However, this could be because black hat hackers are using the wrong kinds of methods An ethical hacker can show a company how they may be vulnerable by levying a new type of attack that no one has ever tried before When they successfully penetrate the system, the organization can then set up defenses to protect against this kind of penetration This unique security opportunity makes the skills of an ethical hacker desirable for organizations that want to ensure their systems are well-defended against cybercriminals

FAQ regarding Penetration Testing on Udemy:
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
What are the different types of penetration testing?
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
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
