Introduction to Cybersecurity

Cybersecurity involves protecting systems, networks, and data from digital attacks. It encompasses a wide range of practices to ensure the integrity, confidentiality, and availability of information. Essential for individuals and organizations, it safeguards against potential cyber threats.

Beyond common viruses, threats include 'zero-day attacks' where hackers exploit software vulnerabilities before developers can fix them. Another threat, 'cryptojacking,' uses your computer's resources to mine cryptocurrencies without your consent, impacting performance and security.

Human error accounts for approximately 95% of cybersecurity breaches. Phishing attacks trick users into revealing sensitive information. Educating employees on recognizing threats and practicing strong password hygiene significantly reduces the risk of breaches.

Beyond firewalls and antivirus software, techniques like 'behavioral analytics' detect anomalies in user behavior that may indicate a breach. 'Honey pots' are decoy systems designed to lure attackers, allowing security teams to study and mitigate malicious activities.

Artificial Intelligence (AI) and Machine Learning (ML) are revolutionizing cybersecurity. They can predict potential threats by analyzing vast amounts of data in real-time. However, cybercriminals also use AI to develop more sophisticated attacks, creating an ongoing cybersecurity arms race.

The first computer virus was created in 1983 by a 15-year-old high school student as a prank, highlighting early vulnerabilities in computer systems.
