Understanding Ethical Hacking 

Ethical Hacking is the authorised attempt to bypass security systems and identify vulnerabilities in computer systems, networks, or applications. Its scope extends to testing and enhancing security measures, protecting against potential cyber threats, and assuring the integrity of digital assets.   

Understanding the definition, scope, and various types of hackers, along with the legal and moral aspects, offers a foundation for comprehending the role of legalised hacking in Cyber Security.

Types of Hackers

The concept of Hacking is quite simple, but it isn’t limited to one role or category. There are various roles in Ethical and Non-ethical Hacking. The three most prominent categories of Hackers are the following: 

a) White Hat Hackers: These Ethical Hackers work with the proper legal methods and guide organisations by detecting the weaknesses in their systems and enhancing security. 

They are usually the ones to whom the bug testing of the applications and website is assigned before releasing them to the public. All Types of Ethical Hacking come under White Hat Hacking.

b) Black Hat Hackers: These hackers are Considered the most notorious cyber-criminals. They are also known as Malicious Hackers who perform illegal activities using the vulnerabilities for malicious purposes or personal benefit. 

They are usually the ones responsible for the Cyber Security breaches and stolen data that cause huge losses to the organisation.

c) Grey Hat Hackers: This group operates in a morally ambiguous space, exploiting vulnerabilities without explicit permission but intending to notify organisations about the weaknesses discovered.

As a result, Grey Hat Hackers are often unpredictable, as the intent behind their actions tends to be unknown.

Legal aspects of Ethical Hacking  

White Hat Hacking operates under strict legal and ethical guidelines, requiring proper authorisation before conducting any security assessments. Once they Become an Ethical Hacker, they must adhere to these principles, respect privacy, and ensure their actions do not disrupt systems or networks or cause harm.

 Once certified, they are expected to follow these standards diligently.

Key skills and knowledge required for Ethical Hackers  

White Hat Hackers require a diverse skill set to identify vulnerabilities and secure systems effectively. The key skills include programming languages, network protocols, and Operating Systems proficiency. They must know hacking techniques, security tools, risk assessment, and strong problem-solving abilities.

White Hat Hackers should also possess excellent communication skills to report findings and collaborate with stakeholders effectively. Furthermore, recognising the essential skills and knowledge needed for Ethical Hacking highlights the expertise and dedication needed to contribute effectively to maintaining digital security.

The process of Ethical Hacking

White Hat Hacking process follows a systematic approach divided into multiple phases. Each phase plays an important role in identifying and addressing security weaknesses. These phases enhance the overall security posture of the target system or network.

Pre-engagement phase

In the pre-engagement phase, the White Hat Hacker establishes clear communication with clients to understand their objectives, scope, and specific requirements. This includes specifying the rules of engagement, obtaining proper authorisation, and signing necessary agreements. Gathering relevant information about the target system or network is necessary before proceeding.

Reconnaissance

 Reconnaissance is also known as footprinting or information gathering. This preparatory phase aims to collect as much information as possible about the target. Before attempting any attack, Ethical Hackers gather essential details like passwords and employee information.  

They might use tools like HTTPTrack to download entire websites or search engines like Maltego to research individuals through various links, job profiles, and news. Reconnaissance is a critical phase in Ethical Hacking. It helps identify potential attacks and assesses how vulnerable the organisation’s systems might be to those attacks.

Vulnerability assessment

During the vulnerability assessment phase, the White Hat Hacker uses various tools and techniques to identify weaknesses in the target system or network. This includes conducting vulnerability scans, analysing configuration weaknesses, and evaluating the effectiveness of security controls. The goal is to find potential vulnerabilities that attackers could exploit.

Exploitation

In the exploitation phase, the White Hat Hacker leverages identified vulnerabilities to gain unauthorised access or escalate privileges within the target system or network. This involves using various hacking techniques and tools to breach defences and assess the impact of the vulnerabilities. The objective is to understand the potential damage an attacker could cause.

Post-exploitation  

After successfully gaining access to the target system or network, the White Hat Hacker focuses on maintaining persistence and exploring the compromised environment further. This stage involves lateral movement, privilege escalation, data extraction, and potentially gaining control over critical systems or sensitive information. It aims to simulate real-world scenarios and analyse the extent of harm that an attacker could cause.

Reporting  

The reporting phase is essential for effective communication between the White Hat Hackers and the client. A comprehensive report detailing the findings, vulnerabilities, potential risks, and recommended countermeasures is generated. The report should be clear, concise, and actionable, providing the client with a roadmap to address and mitigate the recognised vulnerabilities.

Common Ethical Hacking techniques 

White Hat Hackers use various methods to assess the security of systems, networks, and applications. Here are some techniques they use to help organisations identify vulnerabilities, strengthen defences, and ensure the integrity and confidentiality of digital assets.

Network scanning and enumeration  

Network scanning includes systematically exploring a target network to collect information about active hosts, open ports, and services running on them. Enumeration further extracts details like user accounts, shares, and network resources. These techniques help White Hat Hackers identify potential entry points and vulnerabilities in the network infrastructure.

Social engineering  

Social engineering is a strategy that exploits human psychology to manipulate individuals into performing certain actions or revealing sensitive information. It involves tactics like phishing emails, pretexting, baiting, or impersonation. Ethical Hackers utilise social engineering to test an organisation’s awareness and educate employees about the risks associated with such attacks.

Password cracking  

Password cracking involves discovering passwords by systematically trying combinations or using specialised tools. Ethical Hackers use this strategy to test the strength of user passwords and identify weak or easily guessable passwords. This helps organisations enforce stronger password policies and improve authentication security.

Denial of Service (DoS)  

Denial of Service attacks aims to disrupt the availability of a system or network by jamming it with a flood of traffic or exploiting vulnerabilities to exhaust system resources. Ethical Hackers perform DoS attacks to test the resilience and responsiveness of the target infrastructure, allowing organisations to implement appropriate mitigation measures.

Wireless Hacking

Wireless hacking is the exploitation of vulnerabilities in wireless networks, such as Wi-Fi, to gain unauthorised access or intercept network traffic. Ethical Hackers use tools and techniques like brute-forcing Wi-Fi passwords, exploiting weak encryption, or conducting Man-in-the-Middle attacks to identify security weaknesses and enhance wireless network security.

Web Application Hacking

Web Application Hacking focuses on identifying vulnerabilities and weaknesses in web applications, including websites and web services. Ethical Hackers use techniques like SQL Injection, Cross-Site Scripting (XSS), and Session Hijacking to assess the security of web applications. This helps organisations address potential risks and protect sensitive data.
