## TL;DR
AI for network security helps classify traffic, detect anomalies, prioritize alerts, and automate parts of response. It should be framed as decision support inside a security architecture, not as a complete replacement for layered controls and analyst review.

## Core Explanation
Network-security workflows include intrusion detection, DDoS mitigation, user and entity behavior analytics, and zero-trust access decisions. Machine learning can help analyze large traffic volumes and behavioral signals, but the output still needs policy, context, logging, and incident response.

## Detailed Analysis
Datasets such as CIC-IDS2017 are useful for research, but production networks differ in topology, traffic mix, encrypted payloads, and attacker behavior. Strong claims should identify the dataset, traffic type, model role, and operational deployment assumptions.
