Introduction to Machine Learning in Cyber Security
1 Supervised Learning in Security
Supervised learning algorithms learn from labeled historical security data where threat outcomes are known. In cyber defense, this translates to training models on datasets containing both benign and malicious traffic patterns.
Classification: Detect intrusions (binary or multi-class)
Regression: Predict threat severity scores
Examples: Random Forest, SVM, Neural Networks
2 Unsupervised Learning in Security
Unsupervised learning discovers hidden patterns in unlabeled security data without predefined threat labels. This approach excels at identifying novel attack vectors that don't match known signatures.
Clustering: Group similar network behaviors
Dimensionality Reduction: Compress feature space
Examples: K-Means, DBSCAN, Isolation Forest
3 Why ML Enhances SOC Detection
Traditional rule-based systems generate alert fatigue through static signatures. Machine learning models adapt to evolving threats, reduce false positives by 40-70%, and enable security analysts to focus on high-confidence threats rather than processing thousands of low-signal alerts daily.

Security Data Sources for ML Models
Network Logs & Flow Data
NetFlow/sFlow captures aggregated network traffic patterns. Features include source/destination IPs, ports, protocols, byte counts, and packet rates. Ideal for detecting port scanning, DDoS patterns, and data exfiltration.
Features: src_ip, dst_ip, src_port, dst_port, protocol, bytes_in, bytes_out, duration, packet_count
Endpoint Telemetry
Process execution logs, file modifications, registry changes, and system calls from EDR solutions. Captures host-level behavioral indicators for malware detection and lateral movement identification.
Features: process_name, command_line, parent_process, file_path, registry_key, user_account, timestamp
Authentication Events
Login attempts, privilege escalations, and access tokens from identity management systems. Detects compromised credentials, brute force attacks, and unauthorized privilege changes.
Features: user_id, source_ip, auth_method, success_flag, privileges_before, privileges_after, timestamp
// SECTION_03
Anomaly Detection Concepts
Baseline Modeling
Anomaly detection begins with establishing baseline profiles of normal system and network behavior. Models learn statistical distributions of legitimate traffic and user activities during a "quiet" period when threats are assumed minimal.
- → Temporal Patterns: Learn peak hours, weekly cycles, seasonal trends
- → Statistical Profiles: Mean, variance, and distribution parameters per feature
- → Peer Relationships: Compare entity behavior against organizational cohorts
Outlier Identification
Once baselines are established, the model flags statistical deviations. Outliers represent behaviors that deviate significantly from learned patterns and warrant investigation as potential security incidents.
Statistical Methods
- • Z-score / Standard deviation
- • Interquartile range (IQR)
- • Mahalanobis distance
ML-Based Methods
- • Isolation Forest
- • Local Outlier Factor
- • Autoencoders

Enterprise Perspective: SOC Efficiency
Reducing Alert Fatigue
SOC analysts face 10,000+ daily alerts from traditional rules. ML models:
- Reduce false positive rate by 50-70%
- Correlate events intelligently
- Prioritize high-confidence threats
- Enable deeper threat investigation
Improving Detection Efficiency
ML enhances security operations through:
- Real-time anomaly scoring
- Automated incident response
- Behavioral threat hunting
- Compliance reporting automation
