Q & A

What is cybersecurity and why is it necessary?

Cybersecurity is the practice of protecting systems, networks, and data from cyberattacks, theft, and damage. It is necessary because it helps protect personal information, online transactions, and sensitive data, ensuring privacy and security in the digital world.

How does the internet pose a threat to personal data?

The internet connects devices that store personal data, such as phones and computers. Cybercriminals can exploit vulnerabilities in these devices or applications, stealing sensitive information like passwords, credit card details, and personal identities.

What are some common online risks that cybersecurity protects against?

Cybersecurity protects against a variety of risks, such as viruses, hacking, identity theft, data breaches, and cyberattacks that can compromise personal and corporate information.

What is the role of ethical hackers in cybersecurity?

Ethical hackers, also known as white hat hackers, are hired to identify and fix vulnerabilities in systems. They help protect companies and users by reporting weaknesses before malicious hackers can exploit them.

What is the difference between a hacker and an ethical hacker?

A hacker is someone who breaks into systems without authorization, often for malicious purposes, while an ethical hacker works with organizations to identify and fix security vulnerabilities legally and professionally.

What are the different types of hackers?

There are three main types of hackers: black hat hackers (malicious hackers), white hat hackers (ethical hackers), and gray hat hackers (those who may exploit vulnerabilities without malicious intent but without permission).

What is the role of black hat hackers?

Black hat hackers engage in illegal activities such as stealing data, breaking into systems, and causing damage for personal gain or other malicious reasons. They operate outside the law and can cause significant harm.

What is a 'bug bounty' program and how does it work?

A bug bounty program is a reward system where companies pay ethical hackers for identifying and reporting vulnerabilities in their systems. This helps companies fix issues before they are exploited by malicious hackers.

What are script kiddies, and how do they differ from experienced hackers?

Script kiddies are inexperienced individuals who use pre-written hacking tools to exploit vulnerabilities. Unlike experienced hackers, they lack the skills to create their own exploits and typically cause minor disruptions.

What is the difference between state-sponsored hackers and regular hackers?

State-sponsored hackers are employed by government agencies to conduct espionage or cyber defense activities. They have legal access to data and resources. In contrast, regular hackers may engage in illegal activities for personal gain or political motives.
