Introduction
Cyber Security is the discipline focused on protecting digital systems, networks and data from unauthorized access, disruption and malicious exploitation. As digital transformation accelerates, cyber threats have evolved from simple malware into highly organized, persistent and automated attack campaigns.
What is Cyber Security
Cyber Security encompasses technologies, processes and policies designed to defend information systems. It integrates cryptography, network security, application security and human risk management into a unified defense strategy.
Evolution of Cyber Threats
Early cyber attacks focused on viruses and worms. Modern threats include ransomware-as-a-service, advanced persistent threats (APTs), supply chain attacks and AI-powered phishing campaigns.
Malware
Malicious software designed to infiltrate, damage or disable systems, including viruses, trojans and spyware.
Ransomware
Encrypts victim data and demands payment for decryption, often combined with data exfiltration.
Phishing
Social engineering attacks that deceive users into revealing credentials or installing malware.
Core Domains of Cyber Security
Network Security
Protects network infrastructure through firewalls, intrusion detection systems and traffic monitoring.
Application Security
Secures software by identifying vulnerabilities during development and deployment.
Cloud Security
Focuses on protecting cloud workloads, identities and configurations.
Modern Cyber Defense Architecture
Modern cyber defense relies on layered security models such as Zero Trust Architecture, continuous monitoring and threat intelligence integration. Automation and AI are increasingly used to detect anomalies in real time.
Future of Cyber Security
The future of cyber security lies in adaptive defense, quantum-resistant cryptography and AI-driven threat hunting. As attackers become more sophisticated, security strategies must evolve continuously.
