Domains & Why they suit AI research

Below are cybersecurity domains where AI methods typically add value, the common data types and typical tasks for each domain.

Phishing & URL analysis

Data: URLs, HTML, WHOIS, TLS, landing page screenshots. Tasks: binary classification, clustering of campaigns, token attribution. Good for NLP/sequence and tabular ML; abundant labeled datasets.

Malware detection & attribution

Data: static features (imports, strings), dynamic telemetry, assembly traces. Tasks: malicious/benign classification, family attribution, clustering. Suited to multimodal models combining static + dynamic inputs.

Network & host anomaly detection

Data: NetFlow, PCAP, logs, host telemetry. Tasks: unsupervised anomaly detection, time-series forecasting. Large-scale time-series fits deep sequence models and unsupervised methods.

Fraud detection

Data: transactions, device fingerprints, session logs. Tasks: classification, sequence scoring, risk ranking. Operationally important; class imbalance and cost-sensitive learning required.

Threat intelligence & TTP extraction

Data: reports, feeds, passive DNS, indicator graphs. Tasks: entity extraction, link prediction, knowledge graph population. Well-suited to NLP and graph ML.

Insider threat & user analytics

Data: activity logs, access patterns, email metadata. Tasks: anomaly detection, sequence modeling, risk scoring—requires privacy-aware methods and concept-drift handling.

Darknet / Darkweb

Data: forum posts, marketplace listings, crypto traces. Tasks: illicit vs benign classification, seller clustering, link prediction. (Legally sensitive)

Deepfakes & multimedia

Data: images, video, audio, metadata. Tasks: deepfake detection, provenance, localization. (High compute, privacy constraints)

IoT & Smart City

Data: sensor telemetry, device logs, SCADA traces. Tasks: device compromise detection, sensor anomaly, predictive maintenance.

Datasets, features & practical tips

Common features used in security tasks
