Ethical Hacking is the testing methodologies carried out by white hat hackers to identify potential threats and vulnerabilities of a computer system, application software or network in order to ensure optimal security. Ethical Hacking is also known as White Hat Hacking or Penetration Testing and it's being performed by a certified ethical hacker with full permission.
Ethical Hackers check and test system vulnerabilities. They give advice on how these loopholes or vulnerabilities can be properly fixed.
An Ethical Hacker, who is also known as a white-hat hacker, is an information security expert who with permission attempts to penetrate a computer system, network, application or another computing resource on behalf of its owners in order to find security vulnerabilities that a malicious hacker could potentially exploit.
Ethical Hackers basically attempt to bypass system security and look for any weak points that could be exploited by malicious hackers. The gathered information is then used by the organization to improve the system security, to minimize or eliminate any potential attacks.
The purpose of Ethical Hacking is to evaluate the security of and identify vulnerabilities in systems, networks or system infrastructure.
For hacking to be deemed ethical, the hacker must obey rules below:
1. Hackers must respect the individual's or company's privacy.
2. Hackers must express (often written) or have permission to probe the network and attempt to identify potential security risks.
3. Hackers must secure their work, not leaving anything open for you or someone else to exploit at a later time.
4. Hackers must notify the individual or company for any known security vulnerabilities you discovered in their systems, software or server, if not already known by the company.
5. Hackers must carry out hacking activities only to the benefit of the company and not for personal use or gains.
White Hat Hackers or Ethical Hackers are security specialists who specialize in penetration testing methodologies to identify vulnerabilities of an organization's information systems, software or network to ensure adequate security.
Black Hat Hackers are those individuals who attempt to find a computer or software security vulnerabilities and exploit them for personal gains.
Grey Hat Hackers are the computer security expert who sometimes violates laws or ethical standards, but does not have the intention of exploiting them for personal gains.
Ethical Hacking varies based on the system and devices involved.
The following are types of Ethical Hacking:
Web Application Hacking: A web application is an application that is accessed by users over a network such as the Internet or an intranet. They provide an interface between end-users and web servers through a set of web pages generated at the server end or that contain script code to be executed dynamically within the client Web browser. So web application hacking to the exploitation of applications via HTTP which can be done by manipulating the application via its graphical web interface, tampering the Uniform Resource Identifier (URI) or tampering HTTP elements not contained in the URI. Methods that can be used to hack web applications are SQL Injection attacks, Cross-Site Scripting (XSS), Cross-Site Request Forgeries (CSRF), Insecure Communications, etc.
System Hacking: System hacking is the compromise of computer systems and software to gain access to the target computer and steal or misuse the stolen sensitive information without the owner's permission. This is simply the way hackers get access to individual computers on a network using different techniques.
Web Server Hacking: A web server is either the hardware or software dedicated to run a computer application that helps to deliver content that can be accessed through the Internet and World Wide Web. Web server simply to deliver web pages or data on the request to clients using the Hypertext Transfer Protocol (HTTP). Web Server Hacking is simply the act of gaining access to a web server in order to steal information, stop its operation or delete the database with no permission using various methods. Most hackers attack web servers to steal credential information, passwords, and business information by using DoS (DDoS) attacks, SYN flood, ping flood, port scan, sniffing attacks, and social engineering attacks.
Wireless Network Hacking: A wireless network is a set of two or more devices connected with each other via radio waves within a limited space range. Wireless networks are widely used and it is quite easy to set them up. They come with excellent advantages- connectivity beyond walls, wireless connection, easy to access the internet even in areas where laying cables is difficult, speed and sharing. However, they still have a lot of issues when it comes to security. Wireless Network hacking refers to gaining access to your wireless router password and able to have access to the internet through it or been able to steal data from other computers connected to the router. There are various publicly know ways to hack wireless networks e.g WEP and WPA cracking, Man in the Middle (MITM) Attack, Sniffing, Denial of Service Attack, etc.
Social Engineering: This is basically the art of manipulating people to give out confidential information. Its a type of confidence trick and psychological manipulation with the purpose of gathering information, frauding its victims, or gaining system access. These attacks usually happen in one or more steps. The hacker, first of all, investigates the targetted victim to gather necessary background information, such as potential points of entry and weak security protocols, needed to proceed with the attack. Afterward, the hacker gains the victim's trust and prompt the victim for details against security practices, such as revealing sensitive information or granting access to critical resources.
Some of the advantages of Ethical Hacking include:
1. It helps to build a reliable security system that helps to prevent unauthorized access.
2. It helps to secure our computers, gadgets and networks against black hat hackers.
3. It helps to fight against national security and terrorism breaches.
4. It helps to identify and fix vulnerabilities to protect against real hackers.
5. It provides the required financial security in financial sectors.
6. It helps to prevent loss of information and valuable data.
Some of the advantages of studying Ethical Hacking include:
1. It helps students to understand the basics of hacking as a legal profession.
2. It equips students with the knowledge of the various types of hacking as classified based on their intents.
3. It helps students to understand the potential threat to computers, software or network systems together with protective measures.
4. It helps to understand testing security measures and finding vulnerable areas to prevent exploit.
5. It helps to gain the various skills required to become a professional ethical hacker such as the knowledge of programming languages, knowledge of search engines, etc.
6. It creates job opportunities for Ethical Hackers.
7. It creates a self-employment opportunity.
8. Ethical hacking certification opens up a lot of career opportunities with a higher pay scale.
Some of the things you will learn in this course include:
The benefits of becoming an Ethical Hacker, its advantages and how your organization can benefit from it. You will understand the pros and cons of Ethical Hacking and the purpose. Also if and when a vulnerability is found, how the Ethical Hacker documents the issue and offers advice on how to fix these issues.
Analysis of a company's information security status, as an Ethical Hacker you must always scan for weaknesses, prioritize targets, test entry points and develop a strategy that best secures your company's resources. You will understand that to be a competent Ethical Hacker you must understand how to check, test and offer advice on fixes promptly.
You will learn how intruders or black hat hackers use loopholes or vulnerabilities to gain access and privileges and how to secure them. Also the ability to conduct robust vulnerability assessments such as Intrusion detection, policies, cyber laws, social engineering, DDoS attacks and virus detections.
You will learn about terms like trojans, viruses, backdoors, malware, worms in relationship with ethical hacking and the activities which the attacker engages in to perform various attacks including the countermeasures such as the use of Anti-viruses, firewalls, etc.
Other areas covered are ARP poisoning techniques, IP and MAC addresses, and their various representations and formats. Also the ARP poisoning countermeasures and how to configure ARP entries in windows, networks, password sniffing and various protocols that are vulnerable.
