Cyber Threat Detection
This application area focuses on detecting malicious activity in networks, systems, and applications by analyzing security telemetry such as logs, network flows, and endpoint events. Instead of relying solely on static signatures and manual rules, these systems learn patterns of normal and abnormal behavior to identify intrusions, malware, lateral movement, and other cyber-attacks in real time or near real time. They are typically implemented in or alongside intrusion detection systems (IDS), SIEMs, and modern security analytics platforms. It matters because traditional rule-based tools struggle with the scale, speed, and evolving nature of today’s threats, leading to high false positives, missed novel attacks, and analyst overload. Advanced models—ranging from classical machine learning to deep learning, transformers, and large language models—are used to improve detection accuracy, adapt to new attack techniques, correlate signals across large, noisy data sets, and automate parts of triage and response. The result is more effective, timely detection with less manual effort for security teams.
The Problem
“Detect intrusions in real time from logs, flows, and endpoint events”
Organizations face these key challenges:
SIEM alerts are noisy; analysts chase false positives and miss real attacks
New or living-off-the-land attacks bypass signature-based IDS rules
Telemetry is siloed (EDR, network, identity, cloud), making correlation slow
Detection rules drift as infrastructure and attacker behaviors change
Impact When Solved
The Shift
Human Does
- •Write and maintain IDS/SIEM rules, signatures, and correlation logic manually
- •Review and triage the majority of alerts one by one in SIEM/IDS consoles
- •Manually correlate events across logs, endpoints, and network tools to reconstruct attacks
- •Investigate user and device anomalies by hand (IP reputation checks, log searches, pivoting)
Automation
- •Basic pattern matching using static signatures (e.g., known malware hashes, IOC lists)
- •Threshold-based alerts on simple metrics (e.g., login failures, traffic volume spikes)
- •Simple correlation of events based on fixed rule chains within SIEM or IDS
- •Scheduled reporting and dashboards without intelligent prioritization
Human Does
- •Define risk appetite, escalation criteria, and review policies for AI-driven detections
- •Investigate and respond to high-severity, AI-prioritized incidents and complex cases
- •Validate and refine AI models’ outputs, handle edge cases, and approve containment actions
AI Handles
- •Continuously learn baselines of normal behavior across users, hosts, applications, and networks
- •Detect anomalies, suspicious patterns, and multi-stage attack chains across large telemetry streams
- •Auto-enrich alerts with context (threat intel, asset criticality, historical behavior) and severity scoring
- •De-duplicate, cluster, and prioritize alerts to reduce noise and focus analyst attention

Quick Win
Rule-Backed Alert Triage Scorer
Start by prioritizing existing SIEM/IDS alerts using simple statistical baselines and a lightweight risk score (e.g., unusual login location + high privilege + rare process). This reduces alert fatigue without changing underlying controls. Outputs are a ranked alert queue and a daily digest for analysts.

Machine Learning for Cybersecurity Threat Detection, Prevention, and Response
This is like giving your company’s security cameras and fire alarms a brain that learns. Instead of waiting for a fixed list of ‘bad things’ to happen, machine learning watches all activity on your network, learns what “normal” looks like, and then flags and blocks suspicious behavior in real time—often before humans would even notice.
Machine-Learning & Deep-Learning Based Intrusion Detection Systems (IDS)
This is a research survey that acts like a “buyers guide plus textbook” for using AI to catch hackers. It reviews how different machine‑learning and deep‑learning techniques can watch network and system traffic, learn what normal looks like, and automatically flag or block suspicious behavior in real time.
Transformers and Large Language Models for Efficient Intrusion Detection Systems
This work is like a field guide for security teams on how to use ChatGPT‑style AI brains to spot hackers on a network. It doesn’t build one product; it reviews and compares many ways researchers are using transformer and large language models to detect intrusions faster and more accurately than traditional rule-based systems.
Survey of Machine Learning Approaches for Cyber-Attack Detection
This is a research paper that acts like a ‘buyer's guide’ for cybersecurity AI models. It reviews and compares different machine learning methods used to spot cyber-attacks in network traffic and systems logs, highlighting what works best in which situations.
