Understanding AI in Cybersecurity
What is AI in Cybersecurity?
Artificial Intelligence (AI) in cybersecurity refers to the use of machine learning (ML), deep learning, and automation to detect, prevent, and mitigate cyber threats. AI systems can analyze massive datasets, detect anomalies, and respond to threats without human intervention.
How AI Differs from Traditional Cybersecurity?
| Feature | Traditional Cybersecurity | AI-Powered Cybersecurity |
|---|---|---|
| Threat Identification | Reactive (detects known threats) | Proactive (predicts new threats) |
| Data Processing Speed | Slower due to manual analysis | Processes data in real time |
| Attack Mitigation | Human intervention required | Automated mitigation |
| Scalability | Limited to predefined rules | Learns and scales dynamically |
Unlike traditional security that relies on rule-based detection, AI leverages data patterns, predictive analytics, and automation to neutralize cyber threats before they cause damage.
