What Is Ethical Hacking & What Does An Ethical Hacker Do?

Ethical hacking involves authorized experts testing systems to find and fix security flaws. Unlike malicious hackers, ethical hackers work with permission to strengthen defenses.

They identify vulnerabilities before criminals can exploit them. This proactive approach helps prevent data breaches and cyberattacks.

In today’s digital age, protecting information is crucial. Ethical hackers play a key role in safeguarding sensitive data and maintaining trust in technology.

Ethical Hacking: Hack Like A Hero

What Is Ethical Hacking?

The goal is to identify weaknesses that malicious hackers could exploit and they also recommend measures to strengthen security.

Ethical hackers use the same tools and techniques as cybercriminals use but with the owner’s permission and for defensive purposes.

This proactive approach helps organizations protect their data and maintain trust with their users.

Is Ethical Hacking Legal?

It is legal when done with proper authorization. The Ethical hacker definition is that they are also known as white hat hackers which are professionals hired to identify and fix security vulnerabilities in systems.

They operate with the consent of the system’s owner which ensures their activities comply with laws and regulations.

The unauthorized hacking even with good intentions is still illegal and can lead to severe penalties. Obtaining explicit permission before engaging in any hacking activities is essential.

Types of Ethical Hacking

→ Web Application Hacking: Assessing the security of web applications by identifying vulnerabilities like SQL injection, cross-site scripting (XSS) and insecure configurations.

→ Network Hacking: Evaluating the security of an organization’s network infrastructure to detect issues such as open ports, weak passwords and potential entry points for attackers.

→ System Hacking: Focusing on gaining access to individual computers within a network to test for vulnerabilities like weak user credentials and unpatched software.

→ Social Engineering: Manipulating individuals into divulging confidential information or performing actions that compromise security, highlighting the human element in cybersecurity.

→ Wireless Network Hacking: Testing the security of wireless networks to prevent unauthorized access and data breaches.

Each type requires a unique approach and set of tools, but all aim to enhance an organization’s security posture by identifying and addressing potential threats before malicious actors can exploit them.

What Is Unethical Hacking?

Unlike ethical hackers who help secure systems, unethical hackers exploit weaknesses for personal gain or to cause harm.

Their actions can lead to data theft, financial loss and widespread disruption.

Is Unethical Hacking Legal?

Unethical hacking is 100% illegal. It means breaking into systems without permission.

Hackers steal data, spread viruses and crash websites. Laws worldwide strictly punish cyber criminals. Unlike ethical hacking which protects systems, unethical hacking causes harm.

If caught, hackers can face heavy fines and jail time.

Types of Unethical Hacking

There are many ways hackers attack. Phishing tricks people into giving passwords. Malware attacks infect computers with harmful software. DDoS attacks flood websites which makes them crash.

Identity theft steals personal data for fraud. Unlike ethical hacking, these methods have no legal use. With cybercrime on the rise, understanding data security threats is essential.
