- Confidentiality: Ensuring that sensitive information is accessible only to authorized individuals.
- Integrity: Safeguarding data from being altered or tampered with.
- Availability: Guaranteeing that systems and data are accessible when needed.
⚙️ Key Areas
- Network Security: Protecting communication channels from intrusions and misuse.
- Information Security: Securing data in storage and transit.
- Application Security: Building software resistant to threats and vulnerabilities.
- Operational Security: Managing processes and decisions to protect assets.
- Disaster Recovery & Business Continuity: Planning for resilience after cyber incidents.
🚨 Common Threats
- Malware (viruses, worms, ransomware)
- Phishing attacks
- Denial-of-Service (DoS) attacks
- Insider threats
- Zero-day exploits
🧰 Defense Strategies
- Firewalls and intrusion detection systems
- Encryption
