A massive Yahoo data breach in 2013 compromised billions of user accounts. WannaCry ransomware attack in 2017 affected computers in over 150 countries, resulting in huge losses of millions of dollars. These incidents show the dark side of hacking, where vulnerabilities are exploited to cause widespread damage. 

To combat these threats and attacks, Big companies like Google and Facebook hire ethical hackers, also known as white hat hackers. With permission, they rigorously test their systems for weaknesses and vulnerabilities. This sums up what an ethical hacking professional does. These hackers are armed with various ethical hacking tools and techniques to fight against potential data breaches and threats to the company. 

Ethical Hacking

Ethical hackers' jobs are not just about fixing holes but about staying several steps ahead of malicious black hat hackers, who exploit vulnerabilities for nefarious purposes. By identifying and addressing security issues, ethical hackers help safeguard the digital fortress, preventing potential disasters and saving companies from the kind of breaches that have made headlines in the past.

What is Ethical Hacking?

Ethical hacking is the practice of intentionally trying to break into computer systems or networks to find and fix security vulnerabilities. Unlike malicious hackers, ethical hackers operate with permission from the organization they are testing. Their goal is to improve security by identifying weaknesses before they can be exploited by attackers. In lay terms, ethical hackers help make systems safer by thinking like a hacker but acting to protect the system.

Key Concepts of Ethical Hacking

Here are the key concepts of ethical hacking:

Key Concepts of Ethical Hacking Details
Stay Legal Ensure proper approval is obtained before accessing systems or conducting security assessments.
Define the Scope Clearly establish the boundaries of the assessment to keep the work legal and within approved limits.
Disclose Findings Report all identified vulnerabilities to the organization and provide recommendations for fixing them.
Respect Data Sensitivity Adhere to data sensitivity rules, including signing nondisclosure agreements and meeting other requirements set by the organization.

Difference Between Ethical Hackers and Malicious Hackers

Here's the key differences between ethical hackers and malicious hackers:

Aspect Ethical Hackers Malicious Hackers
Purpose Secure and improve organizational technology. Gain unauthorized access for financial gain, personal fame, or harm.
Actions Identify vulnerabilities, report them to the organization, and suggest fixes. Exploit vulnerabilities for personal benefit without reporting them.
Impact Help strengthen security and prevent breaches. Damage systems, deface websites, or cause financial and reputational harm.
Follow-Up Perform retests to ensure vulnerabilities are resolved. Do not assist in improving security or resolving issues.
Ethics Work legally with approval to protect resources and data. Operate illegally, often targeting sensitive data for malicious purposes.

Skills and Certifications for Ethical Hacking

Common Vulnerabilities Discovered by Ethical Hackers

Here are some of the common vulnerabilities that ethical hackers try to fnd:

Vulnerability Description
Injection Attacks Occur when untrusted data is sent to an interpreter, leading to unauthorized access or data leakage.
Vulnerability Chaining Exploiting multiple vulnerabilities together to achieve a more significant security breach.
Sensitive Data Exposure Happens when sensitive information, like personal or financial data, is not properly protected.
Security Misconfigurations Result from improper settings in applications or servers, exposing systems to attacks.
Business Logic Vulnerabilities Exploiting flaws in the application's workflow to bypass intended processes or gain access.
Broken Authentication and Authorization Weak or flawed mechanisms that allow attackers to impersonate users or access restricted resources.
Use of Components with Known Vulnerabilities Using outdated or insecure software components that can be exploited by attackers.
