Ethical Hacking: The Art of Securing Systems by Thinking Like a Hacker


The world of technology has exponentially grown, providing numerous benefits that have simplified people’s day-to-day lives. However, alongside these benefits also come potential vulnerabilities for malicious hackers to exploit. As a result, it has become necessary to have ethical hackers who can help identify and patch vulnerabilities before hackers with malicious intent can exploit them. This article dives into ethical hacking and its significance in securing systems.

Definition of ethical hacking

Ethical hacking is a process where a security professional, commonly referred to as a “white hat hacker”, uses the same techniques and tools as a malicious hacker to locate vulnerabilities in a system and report them back to the organization to fix. It is a proactive approach to identify weak spots in the system and fix them before the system is exploited by malicious hackers. Ethical hacking aims to secure the system and prevent attacks from happening.

Importance of ethical hacking in securing information

The importance of ethical hacking is immeasurable, as it plays a critical role in identifying and eventually fixing potential security breaches. Cybersecurity incidents are increasing, and companies can avoid any breaches by hiring ethical hackers to assist them in identifying vulnerabilities in their system. Ethical hacking is not only crucial to protect the organization’s data but also the individual’s personal information available on the system.

Understanding the Mind of a Hacker

To think like a hacker, it’s essential to understand their motivation. Hackers are driven by different factors like financial gain, curiosity, revenge, and political motivation, among many others. Understanding the types of hackers and what motivates them, enables security professionals to develop practical approaches to identify and counter their attacks before they happen. The different types of hackers include white hat hackers, black hat hackers, grey hat hackers, and hacktivists.

The Phases of Ethical Hacking

Ethical hacking has different phases that help security professionals identify and counter potential threats in the system. These include:


Reconnaissance is also known as footprinting. In this phase, the hacker gathers information about the system. The information includes the target system’s IP range, system architecture, employee information, and company information.


Scanning is the process of discovering open ports and vulnerabilities of the target system. The information gathered helps the hacker identify the right tools and techniques to use in gaining access to the system.

Gaining Access

This phase involves the hacker trying to access the target system. The hacker may use multiple techniques like password cracking, social engineering, or exploiting system vulnerabilities to gain access to the system.

Maintaining Access

The hacker will try to maintain access to the system by creating backdoors or using remote access tools. The purpose of this phase is to make sure the hacker will still be able to access the system even after the organization has patched the vulnerability.

Covering Tracks

The hacker will try to cover their tracks by deleting logs and removing any indication that they accessed the system. Their aim is to avoid being traced back to the breach.

Ethical Hacking Tools and Techniques

Ethical hacking tools and techniques are essential for security professionals to identify vulnerabilities and test their security measures. It is crucial to use ethical hacking tools and techniques to ensure tests are carried out safely and securely. These include:

Overview of ethical hacking tools

Ethical hacking tools are software programs created explicitly for identifying vulnerabilities in a system. These tools help security professionals identify loopholes in the system, ultimately resulting in a more secure system.

Some popular ethical hacking tools include Nmap, Metasploit, the Open Web Application Security Project (OWASP), and Burp Suite. These tools are used for scanning, testing web application vulnerabilities, and breaking in or exploiting the system’s weakness.

Techniques used in ethical hacking

The different types of techniques used in ethical hacking are network scanning, vulnerability scanning, password cracking, social engineering, physical testing, and various other techniques to exploit vulnerabilities.

Common Network Security Vulnerabilities

Network security vulnerabilities are a hotspot for malicious attackers because they enable them to exploit a system in various ways. The most common network security vulnerabilities are:

Network vulnerabilities and their exploitation

Network vulnerabilities can be exploited through several methods. These include denial of service attacks, packet sniffing, session hijacking, MAC Spoofing, DNS Spoofing, and various other methods.

Types of attacks possible

Some of the most common attacks include man-in-the-middle attacks, brute force attacks, phishing attacks, and malware attacks.

Web Application Security

With the growth of web applications in businesses, comes an increase in vulnerabilities that can be exploited. Understanding web application security helps in identifying and fixing potential security breaches.

Understanding Web Applications

Web applications are software applications running on web servers or accessed by the client through a web browser. Understanding how web applications work and operate helps in identifying potential vulnerabilities and securing the application.

Common web application vulnerabilities and how to exploit them

Some common web application vulnerabilities include SQL Injection, Cross-Site Scripting, File Inclusion, and other vulnerabilities that can be exploited by using different techniques and tools.

Social Engineering: The Art of Human Hacking

Social engineering is an attack method aimed at manipulating individuals into divulging sensitive information that can be used to exploit network security.

Introduction to social engineering

Social engineering is an attack method widely used by hackers to gain access to systems by exploiting human psychology. The technique involves extensive knowledge of social interactions and communicating with people to obtain sensitive information.

Types of social engineering attacks

The most common social engineering attacks are phishing, pretexting, baiting, tailgating, and quid pro quo.

Password Cracking Techniques

Password cracking techniques are used by hackers to obtain passwords and access systems illegally.

Need for password cracking techniques

Passwords can be the weakest link in the security chain. It is thus essential to understand the different password cracking techniques used by hackers and employ countermeasures to prevent them.

Popular password cracking techniques include Brute Force attacks, Dictionary attacks, Rainbow Tables, and Hybrid attacks.
