Explore cyber threats, ethical hacking, cryptography, and network security.
Cybersecurity refers to the protection of digital systems, networks, and data from cyber threats like hacking, malware, and data breaches.
Cybersecurity is crucial for safeguarding personal, corporate, and government data against cyberattacks.
Cybersecurity measures protect systems, data, and users from threats:
Ensuring cybersecurity involves multiple layers of protection and continuous monitoring:
The evolution of cybersecurity has been driven by the need to protect digital systems from emerging threats. Below is a timeline highlighting key milestones.
With the rise of computers, the first security threats appeared. The first computer worm, "Creeper," was created in the 1970s, leading to the first antivirus program.
As the internet grew, cyber threats like malware, phishing, and network breaches emerged. The first firewall was developed to protect networks.
Major cyberattacks led to security laws like HIPAA, PCI-DSS, and GDPR. Organizations started investing in cybersecurity strategies.
Cybercriminals used advanced techniques like ransomware, DDoS attacks, and AI-driven hacking, increasing the need for stronger security defenses.
With cloud computing and IoT growth, Zero Trust security models and AI-driven cybersecurity solutions are now essential.
Quantum computing and AI will revolutionize security, enabling both stronger encryption and more sophisticated cyber threats.
Learn how to secure networks using firewalls, VPNs, and encryption.
