Challenges of AI in Cybersecurity
Adversarial AI: Cyber-criminals are also using AI to craft sophisticated attacks.
Bias in AI Models: Poorly trained models can overlook genuine threats or generate false positives.
Dependence on Data: AI’s effectiveness is limited by the quality and quantity of data it learns from.
Cybersecurity has transformed from simple antivirus software to an intricate, AI-enhanced shield protecting our digital world. As threats grow in complexity, cybersecurity will remain a cornerstone of technological progress. Whether it’s safeguarding personal data, national infrastructure, or emerging technologies like IOT and quantum computing, the need for strong, adaptive, and intelligent security systems is both urgent and eternal.
Cybersecurity isn't just a profession—it’s a necessity for the digital age.
