    Ethical Hacking vs Penetration Testing: Discover the Differences!

    Both ethical hacking and penetration testing provide similar functionalities and are classified as "Offensive Security,". But when it comes to internal cyber security tests, the terms "penetration testing" and "ethical hacking" are frequently used interchangeably, although they're not the same. Cybersecurity specialists often misunderstand the distinctions between the two. Since they are employed in different situations to achieve various purposes, knowing the differences between ethical hacking vs penetration testing is crucial for anyone and everyone responsible for securing business systems and networks.

    The differences between ethical hacking and penetration testing are so striking that you do not want to hire an ethical hacker when you need a penetration tester, and vice versa. This is because you'll get a service that doesn't fit your needs. On top of these two, we also have social engineering, red teaming, software reverse engineering, and other offensive security professionals as well. But here, we'll discuss the differences between Ethical Hacking and Penetration Testing.

    What is Ethical Hacking?

    Ethical hacking refers to hacking motivated by ethical or moral values rather than harmful intent. Ethical hacking is any sort of hacking that the target system's owner has approved. It can also refer to putting proactive security measures to guard against malicious hackers.

    Ethical hacking has become a popular and preferred approach to analyzing a company's security systems and practices. An ethical hacker with a CEH course certification combines security judgment, red teaming, intrusion testing, and vulnerability assessment. Consider the following points as you learn more about hacking and its importance.

    Types of Ethical Hackers

    1. Black Hat Hackers

    Black Hat Hackers are skilled hackers who gain access to a system without permission and take advantage of a system's security for nefarious purposes or financial gain. Organized crime groups are common partners for black hat hackers, and crackers are another name for them. They may also use malware to steal personal information and credit card information, corrupt files, and disrupt the security network.

    2. White Hat Hackers

    Ethical hackers are another term for white hat hackers. As part of penetration testing and vulnerability assessments, they never intend to harm a system; instead, they strive to uncover holes in a computer or network system. Ethical hacking is not a crime and is one of the most challenging positions in the IT sector. Many businesses use ethical hackers to do penetration tests and vulnerability assessments.

    3. Grey Hat hackers

    They combine elements of both black and white hat hacking. They act without malice, but for amusement, they exploit a security flaw in a computer system or network without the permission or knowledge of the owner. Their goal is to bring the weakness to the owners' attention and gain gratitude or a small reward.

    Importance of Ethical Hacking

    • Ethical hacking is quite beneficial in the workplace for testing security solutions. It ensures that all systems are safe from black hat hackers. Hacking assaults are becoming more common, so ethical hacking is an in-demand skill.
    • Ethical hacking is used to protect sensitive information from adversaries. It protects your computer from extortion by those looking to exploit a weakness. A corporation or organization can discover security vulnerabilities and hazards using ethical hacking.
    • Trained ethical hackers are a key strength of any corporation. For instance, ethical hackers with cybersecurity certifications can do rapid security tests under extreme and ordinary settings to ensure that the software performs properly.
    • Ethical hacking in the workplace helps you detect software security flaws. You can examine your security from a hacker's perspective and correct any abnormalities before they become a problem for the company's business.

    What Is Penetration Testing?

    Pen testing is ethical hackers launching pre-planned attacks against a company's security infrastructure to identify security flaws that need to be addressed. Pen testing is a crucial component of a comprehensive web application security approach, and it refers to the methods that hackers use to test an application. Pen-testing is carried out to have no impact on the application's regular operation.

    Types of Penetration Testing

    1. Open-box pen test

    In this type of penetration testing, the hacker receives some information about the target company's security ahead of time.

    2. Covert pen test

    A 'double-blind' pen test is another term for this test. This is a circumstance in which nearly no one in the firm, including the IT and security professionals responsible for defending against the attack, is aware that the pen test is taking place. To minimize complications with law enforcement, covert testers need to have the scope and other parameters of the test written down ahead of time.

    3. External Pen Test

    A security examination of an organization's perimeter systems is known as external penetration testing (also known as external network penetration testing). All systems directly accessible from the internet are included in your perimeter.

    4. Internal Pen Test

    Internal penetration testing simulates a situation in which an attacker has already gained access to a compromised machine or is physically present in the facility. It's usually best to start with the basics and only consider internal testing after regular vulnerability scanning and external penetration testing have been completed.

    Importance of Penetration Testing

    Penetration testing is a technique for evaluating the security mechanisms in a system. It aids organizations in improving the effectiveness of their security processes and controls. Any cyber security strategy should include penetration testing as well. Penetration testing ensures that an organization's systems, applications, and networks are secure. It is used to detect security flaws before criminals discover them. Penetration testers (sometimes known as "pentesters") mimic assaults to uncover security flaws. This procedure aids an organization in identifying and correcting weaknesses before a criminal can exploit them.
