Ethical hacking is often a process commonly accepted by big players in the technology industry in order to safeguard their organizations from future investigations by malicious hackers. Under this Ethical Hacking Tutorial, I'll go over some of the most important aspects of this globally practiced discipline. The following topics will be covered such as ethical hacking, ethical hacker roles, why ethical hacking security threat, ethical hacking skills, tools, etc in an elaborate manner.
What is ethical hacking?
The act of hacking is defined as the process of identifying and exploiting a set of vulnerabilities in a target system. Ethical hacking distinguishes itself from hacking by incorporating a critical component into the process – 'consent.' The addition of the term "consent" to this process serves two purposes:
Ethical hacker roles:
Ethical hackers play a variety of roles within the organizations for which they work. Given that ethical hacking is used by both public and private organizations, the objectives could be diverse, and they can be comes down to some few important aspects –
Why is ethical hacking important?
Data has evolved into a valuable resource. As a result, the preservation of privacy and data integrity has grown dramatically. In core, this makes ethical hacking critical today!This is significant to mention that virtually every company seems to have a website. The internet was used as a form of media for public relations, digital marketing, and sales. As a result, any end state used to represent the platform is potentially vulnerable.
Besides that, hackers of today have demonstrated to be creative geniuses whenever it comes to breaking into a system. Battling fire with fire may not work in real life, but a system needs others with the same thought process to combat a hacker of this caliber.Latest hacking outages have resulted in millions of dollars in losses. These incidents have served as a wake-up call to businesses all over the world, prompting them to reconsider the importance of ethical hacking and cybersecurity.
After laying the groundwork for ethical hackers by defining their roles and significance to an organization, let's all keep moving on to evaluate some critical components of ethical hacking throughout this ethical hacking tutorial.
What is a security threat?
As an ethical hacker, you would have to deal with a variety of security threats on a daily basis.
A security threat would be any risk which has the ability to ruin a system or a company as a whole. Let's go through the kinds of security threats.
Types of threats:
There are two kinds of threats:
Physical threats are further classified into three types.
Non-physical threats are any threats that do not have a physical manifestation. They are also referred to as logical threats. On a daily basis, an ethical hacker deals with non-physical threats, and it is his responsibility to devise preventive measures for these threats.
Preventive measures for security threats:
Since most protection strategies used by ethical hackers vary by organization due to unique needs, individuals can be ultimately boils down to a few key methodologies which are universally followed –
After discussing the kinds of threats that an ethical hacker encounters on a regular basis, let's go over the skills required to deal with the threats discussed in this ethical hacking tutorial.
Ethical hacker skills:
A computer programmer who focuses on networking and penetration testing is known as an ethical hacker. This typically necessitates the following skill set –
Why do we need programming languages?
Since I've discussed that programming is a requirement for ethical hacking, I've been asked why. This is primarily due to people's lack of understanding of the roles and responsibilities of an ethical hacker. Here are a few of the reasons why programming knowledge is essential for an ethical hacking career:
Ethical hackers seem to be problem solvers and tool builders; learning to code will assist you in implementing solutions to problems.
Programming also aids in the automation of tasks that would otherwise take up valuable time to complete.
Writing programs could also assist you in identifying and exploiting programming flaws in the applications you will be targeting.
Programming knowledge can also be used to customize pre-existing tools to meet your specific requirements. For example, Metasploit is written in Ruby, and if you know how to write one in Ruby, you can add a new exploit to it.
Now we will discuss the ethical hacking tools in a more detailed way.
Ethical hacking tools:
Because it is difficult to prevent every ethical hacking tool available in a single article, I will only cover some of the most well-known ones in this section:
Now we will talk about social engineering in a detailed way.
Among many other malicious attacks, social engineering will have demonstrated to become a very important manner of hacking. The term encompasses a wide range of malicious activities carried out through human interactions. It employs psychological manipulation to dupe users into making security mistakes or disclosing sensitive information.The process of social engineering is multi-step. An offender first explores the alleged target to collect more information, such as prospective entry points and strict security procedures, that will be required to carry out the attack.
The attacker then wants to obtain the victim's trust as well as provide stimulation for consequent actions that violate security practices, such as disclosing information or giving access to system systems.
Social Engineering techniques:
Let us now discuss the various methods used for social engineering in this ethical hacking tutorial.:
This is an ethical hacker's responsibility to raise awareness about such techniques within the organization for which he or she works. Now, in this ethical hacking tutorial, let's talk about cryptography and cryptanalysis.
The art of converting text into an unreadable format is known as cryptography. If your data falls into the wrong hands, you can rest easy as long as it is properly encrypted. Only the person in possession of the decryption key will be able to view the data. An ethical hacker is more interested in the operation of algorithms that allow him to decipher data without the use of a key. This is known as cryptanalysis.
Cryptanalysis is the analysis of evaluating systems in order to research the processor architectures' important features. Cryptanalysis is a technique for breaching cryptographic security measures and gaining access to the information of encrypted messages, even when the cryptographic key is unknown. Cryptanalysis has given rise to techniques such as brute force, dictionary attacks, and rainbow table attacks.The achievement of cryptanalysis is determined by the amount of time available, the computational power accessible, and the amount of storage available.
Important cryptographic algorithms:
Here we will learn about the most common cryptographic algorithms. They are:
2.SHA-1 generates hash values of 160 bits. It's similar to previous versions of MD5. It has cryptographic flaws and has not been recommended for use since 2010.
3.SHA-2 is a hash function that has two hash functions: SHA-256 and SHA-512. SHA-256 employs 32-bit words, whereas SHA-512 employs 64-bit words.
4. SHA-3: Keccak was the formal name for this algorithm.
RC4 – this algorithm is used in the creation of stream ciphers. It is most commonly used in protocols like Secure Socket Layer (SSL) to encrypt internet communication and Wired Equivalent Privacy (WEP) to secure wireless networks.
This concludes our discussion of ethical hacking.
