Ethical Hacking

What is mean by Hacking, what is ethical hacking? , how to do ethical hacking?

 

In the modern, technologically connected world, hacking has emerged as a hot topic.  Many people connect the word "hacking" with hackers taking advantage of system vulnerabilities to steal information, disrupt operations, or breach networks. The act of recognising and altering a system's functionality for a specific objective is known as hacking, yet hacking itself is a neutral activity. Hacking is either malicious or helpful depending on its purpose.

Frequent leaks of information and accounts of ethical hackers helping to stop cyberattacks This blog provides an overview of ethical hacking, defines what hacking is, and provides a starting point guide, demonstrate how important it is to distinguish between hacking and ethical hacking.

Different hacker types can be identified based on their intentions and the legality of their conduct.

 

Black Hat Hackers: 

They are hackers who commit crimes or illegal activities. For nefarious reasons, they compromise networks to steal confidential information, spread malware, or interfere with services. These kinds of actions are typical of cybercrimes.

White Hat Hackers:

The expertise of ethical hackers, often known as white hat hackers, is used to assist organisations in safeguarding their networks. The vulnerabilities are found and fixed before malevolent hackers may take use of them.

Gray Hat Hackers: 

Between black hat and white hat hackers, these hackers are in the between. Instead of creating damage, they frequently expose the vulnerabilities they discover, sometimes for a charge, even though they may breach networks without permission. Their activities are technically prohibited even if their purpose is usually not malevolent.

Hacktivists:

Hacking is a tool used by hacktivists to protest or advance environmental, social, or political issues. The targets of their attacks are frequently companies, government agencies, or other groups they believe to be immoral.

 

Ethical Hacking- What is it?

 

The intentional search for flaws in systems to safeguard them, as opposed to using them maliciously, is known as ethical hacking. Ethical hackers, also referred to as "white-hat hackers," are experts who strengthen system security by using their hacking abilities in a legitimate and approved way. Finding flaws in a system, reporting them, and helping to create remedies to fortify its defences are their responsibilities.

Ethical hacking usually entails conducting controlled cyberattacks on a business's software, apps, or network. With the express consent of the system owner, ethical hackers are able to carry out assaults that are intended to resemble those of black hat hackers.

 

Some of the frequent actions of ethical hackers are:

 

Penetration Testing: Pen-testing, often known as penetration testing, is a technique used by ethical hackers to replicate a system attack. It helps them in locating weak points that malicious hackers may take advantage of.

Vulnerability Assessment: Ethical hackers look for known weaknesses in systems, including out-of-date software or weak passwords, and then provide solutions.

Social Engineering: Ethical hackers, like black hat hackers, may employ social engineering techniques to coerce others into exposing private information. To evaluate how vulnerable staff members are to phishing schemes or assaults, ethical hackers, however, take this approach.

Security Auditing: In order to make sure that security guidelines are being followed and that there are no security vulnerabilities in a system's design, ethical hackers frequently examine code and infrastructure.

 

How to Do Ethical Hacking?

 

To enter the field of ethical hacking, one needs a combination of technical expertise, system knowledge, and a thorough comprehension of cybersecurity concepts. Strict legal and ethical regulations must also be followed by ethical hackers. A detailed tutorial on becoming an ethical hacker is listed here:

 

1. Learn the Fundamentals of Operating Systems and Networking:

 

Before becoming an ethical hacker, you must comprehend how operating systems and networks work. To comprehend how data moves across networks and how systems function together, one must be familiar with protocols like TCP/IP, HTTP, FTP, and DNS.

> Networking: Understanding the fundamentals of network protocols, firewalls, routers, switches, and how data is sent across the internet is essential for ethical hackers.

> Operating Systems: Operating system knowledge is required for Windows, Linux, and macOS. Because Linux provides a range of pre-installed tools for security testing, the majority of ethical hackers employ Linux-based tools for penetration testing, such as Kali Linux.

 

2. Learn Programming and Scripting: 

 

In order to test systems and exploit mistakes, ethical hackers need to be proficient in programming. Understanding code will help you identify flaws in software, comprehend how it operates, and create tools for automated testing. The following are a few programming languages that ethical hackers can use:

> Python: Used to automate processes, analyse data and write hacking programs.

> C and C++: Understanding operating systems' and applications' low-level processes is made easier using C and C++.

> JavaScript: Because web-based systems have a lot of vulnerabilities, it is essential for testing online applications.

> SQL: Understanding SQL aids ethical hackers in recognising and preventing SQL injection threats.

 

3. Study Cybersecurity Fundamentals:

 

Ethical hackers need to be well-versed in cybersecurity concepts, such as:

> Encryption and Decryption: The process by which data is safeguarded using encryption techniques such as AES and RSA.

> IDS/IPS and firewalls: Intrusion Prevention Systems (IPS) and Intrusion Detection Systems (IDS) are essential for keeping an eye out for hostile behaviour on networks.

> Authentication and Authorisation: Learning about various authentication methods that protect user access, such as single sign-on (SSO) and multi-factor authentication (MFA), is part of authentication and authorisation.

 

4. Get Hands-On Experience:

 

Being a successful ethical hacker requires more than just theoretical understanding. You must develop your abilities in practical settings. To practise ethical hacking in a safe and legal setting, aspiring hackers can use several platforms and resources:

> Hack The Box: A well-known website that lets you practise penetration testing and other hacking techniques in virtual laboratories is called Hack The Box.

> TryHackMe: Another engaging website that provides organised cybersecurity and ethical hacking courses and challenges.

> Capture the Flag (CTF) Challenges: To earn points and discover ethical hacking techniques, take part in CTF competitions where you must answer security-related problems.

 

5. Use Ethical Hacking Tools:  

 

Ethical hackers do penetration tests and look for vulnerabilities using a range of techniques. Among the most often used tools are:

> Nmap: A network scanner for finding open ports and detecting devices and services on a network.

> Metasploit: The well-known framework Metasploit is used to create and run exploit code against a distant target computer.

> Wireshark: An ethical hacker can use Wireshark, a network protocol analyser, to record and examine network traffic in order to identify weaknesses.

 

Wrapping Up

 

Because hacking is often associated with cybercrime, the term has a negative connotation in its classical definition. To improve security systems, however, ethical hacking is essential because it finds flaws before malevolent hackers can take advantage of them. Networking, cybersecurity, programming, and the use of different penetration testing tools are all necessary to become an ethical hacker. Aspiring hackers may make useful contributions to the field of cybersecurity and assist organisations in safeguarding their systems and precious data by adhering to ethical principles.
