2. Bias and Fairness:

• AI models can inherit biases present in the data they are trained on, potentially leading to discriminatory outcomes.
• Ensuring fairness and transparency in AI algorithms is crucial, especially in sensitive areas such as user authentication and criminal profiling.

3. Privacy Concerns:

• The collection and analysis of vast amounts of data for AI-driven cybersecurity may raise privacy concerns among individuals.
• Striking a balance between security measures and respecting user privacy is essential.

4. Lack of Explainability:

• AI algorithms, particularly in deep learning, are often considered “black boxes” with limited explainability.
• The lack of transparency may hinder trust and understanding, especially in critical decision-making processes.

5. Over-Reliance on AI:

• Over-reliance on AI without human oversight may lead to a false sense of security, potentially overlooking nuanced threats that require human intuition and context.

6. Legal and Regulatory Challenges:

• The legal framework around AI in cybersecurity is still evolving, presenting challenges in terms of liability, accountability, and compliance with regulations.

The Future of AI in Cybersecurity:

1. Evolution of Adversarial Techniques:

• As AI in cybersecurity advances, adversaries are likely to develop more sophisticated techniques to evade detection.
• The perpetual cat-and-mouse game between defenders and attackers will drive continuous innovation.
