Careers in Cybersecurity and Ethical Hacking

What is Cybersecurity?

Cybersecurity refers to the practice of protecting computers, networks, and data from unauthorized access, attacks, and damage. It plays a critical role in safeguarding digital assets, ensuring privacy, and maintaining the integrity of systems.

• Definition of Cybersecurity: Cybersecurity involves the use of technologies, processes, and practices designed to defend against cyber threats.
• Role in Protecting Digital Assets: It ensures the confidentiality, integrity, and availability of information by preventing unauthorized access, data breaches, and cyberattacks.
• Analogy of Cybersecurity as a Digital Lock: Think of cybersecurity as a digital lock on your home. Just as a lock protects your physical belongings, cybersecurity protects your digital information.
• Examples of Cyber Threats:
• Hackers: Individuals who exploit vulnerabilities to gain unauthorized access.
• Malware: Malicious software designed to damage or disrupt systems.
• Phishing: Fraudulent attempts to steal sensitive information through deceptive emails or websites.

What is Ethical Hacking?

Ethical hacking is the practice of intentionally probing systems for vulnerabilities to identify and fix security weaknesses before malicious hackers can exploit them.

• Definition of Ethical Hacking: Ethical hacking involves authorized attempts to bypass security measures to improve system defenses.
• Comparison to Malicious Hacking: Unlike malicious hackers, ethical hackers operate with permission and aim to strengthen security rather than exploit it.
• Role of Ethical Hackers: They act as "good guys" who test systems, much like a security expert testing a bank vault to ensure it’s impenetrable.
• Analogy of Ethical Hackers as 'Good Guys': Ethical hackers are like security consultants who test locks and alarms to ensure they work effectively.
