What is the role of artificial intelligence and machine learning in enhancing cybersecurity for 5G networks, and what are the limitations?</h2>Role of AI and ML in Enhancing Cybersecurity for 5G Networks: Threat DetectionAI and ML are used to detect and identify cybersecurity threats in real-time by analyzing network traffic patterns and behavior anomalies. They can recognize abnormal activities that may indicate a cyberattack, such as unusual data flows, unauthorized access, or malware activity. Anomaly DetectionMachine learning models can establish baselines of normal network behavior and then identify deviations from these baselines. This approach is particularly useful for identifying novel or zero-day attacks that may not be covered by traditional rule-based systems.  Limitations of AI and ML in Cybersecurity for 5G NetworksFalse PositivesAI and ML models can generate false positives, flagging legitimate activities as potential threats. This can lead to alert fatigue and decreased trust in automated systems. Adversarial AttacksAdversaries can manipulate AI and ML models by feeding them misleading data to evade detection. Ensuring model robustness against adversarial attacks is a significant challenge. Data PrivacyML models require access to large datasets to learn effectively. This raises concerns about data privacy and compliance with regulations like GDPR when processing sensitive information.
