The different types of hackers include white hat hackers who are ethical hackers and are authorized to hack systems, black hat hackers who are cybercriminals, and grey hat hackers, who fall in-between and may not damage your system but hack for personal gain. There are also red hat hackers who attack black hat hackers directly. Some call new hackers green hat hackers. These people aspire to be full-blown, respected hackers. State-sponsored hackers work for countries and hacktivists and use hacking to support or promote a philosophy. Sometimes a hacker can act as a whistleblower, hacking their own organization in order to expose hidden practices. There are also script kiddies and blue hat hackers.

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.

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.

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 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.

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.

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.

Hands-on lab exercises implementation of DoS and MiM attacks using ARPEthical 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.

The Internet Protocol (IP) is the principal communications protocol in the Internet protocol suite for relaying datagrams across network boundaries.

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.

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 ethical

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.

Just like Windows, iOS, and Mac OS, Linux is an operating system. In fact, one of the most popular platforms on the planet, Android, is powered by the Linux operating system.

What is Linux and why should I use it?
Linux is an operating system (OS), which is the primary software that a computer uses to execute tasks and communicate directions to its hardware. The operating system that competes the most with Linux is Windows. Linux is a popular and widely-used OS because it is open-source, meaning that it is free to the public, and anyone can modify and customize Linux software as they wish. The reasons to use Linux can vary from developing an app or building a video game to learning how to hack computer systems. As Linux is one of the most popular operating systems, many developers use it to develop their web applications and software programs. This means knowledge of Linux is important for anyone working with computers and software in general. Learning how to work with Linux is a necessary skill for anyone pursuing a career in ethical hacking or penetration testing

Linux has a number of different versions to suit any type of user. From new users to hard-core users, you’ll find a “flavor” of Linux to match your needs. These versions are called distributions (or, in the short form, “distros”). Nearly every distribution of Linux can be downloaded for free, burned onto disk (or USB thumb drive), and installed (on as many machines as you like).

Why do hackers use Linux?
Both ethical (white hat) hackers and malicious (black hat) hackers often prefer to use the Linux operating system (OS) over Windows OS. The biggest reason hackers turn to Linux is because it is far more accessible to a wider range of people than Windows OS offers. Linux is free, open-source, and provides a well-integrated command-line interface for users to customize the OS. This means anyone can modify Linux to create their own programs and software. Malicious hackers often opt for Linux because it gives them more control when using Linux, and ethical hackers need to be well-versed in Linux because it’s so popular among black hat hackers. Ethical hackers also often prefer using Linux as it has better existing security measures than Windows and doesn’t usually require third-party antivirus software.

Address Resolution Protocol (ARP) is the method for finding a host's Link Layer (MAC) address when only its IP address is known. The level 1 scan is passive and looks at connections or ARP cacheWhether 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 courses to help keep your networks safe from cybercriminals.

Passive scanning is a method of vulnerability detection that relies on information gleaned from network data that is captured from a target computer without direct interaction. - Wireshark Passive Monitoring, networking

Following Protocol Streams, To filter to a particular streamEthical 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.

Wireshark is a GUI network protocol analyzer. It lets you interactively browse packet data from a live network or from a previously saved capture file. Wireshark's native capture file format is pcapng format, or pcap which is also the format used by tcpdump and various other tools.

Listening to the traffic. Man in the middle attack, sniffing, spoofing, denial of service, compromising. 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.

Sniffing is a process of monitoring and capturing all data packets passing through given network.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.

Switch: A switch is smarter than a hub. Similar to the hub, it is a connection point for all the devices in the network. ... If the destination address is not available, the switch sends the data packet to all the devices across the network. Router: It is the most intelligent of the three networking devices. Setup hub, setup switch, setup router.

In a typical MAC flooding attack, a switch is fed many Ethernet frames, each containing different source MAC addresses, by the attacker. The intention is to consume the limited memory set aside in the switch to store the MAC address table in ethical hacking

DHCP supports three mechanisms for IP address allocation: Automatic allocation—DHCP assigns a permanent IP address to a client. Dynamic allocation—DHCP assigns an IP address to a client for a limited period of time, which is called a lease (or until the client explicitly relinquishes the address).· metasploit
