A system that ingests, normalizes, scores, and distributes threat data from multiple sources so that analysts and security controls can consume consistent, deduplicated intelligence.
- Confidence and Severity Scoring
- Related: Threat Intelligence Platform, Alert Triage, False Positive
The practice of rating intelligence and alerts by how trustworthy the source is and how much impact the activity would have, so responders can triage limited attention toward the highest-risk findings.
- Diamond Model of Intrusion Analysis
- Related: MITRE ATT&CK, Threat Actor Attribution, Threat Hunting
An analytic framework relating four core features of any intrusion, namely adversary, capability, infrastructure, and victim, with edges that reveal how the features interact and where pivoting is possible.
- Threat Actor Attribution
- Related: Diamond Model of Intrusion Analysis, Tactics, Techniques, and Procedures, Threat Intelligence Platform
The analytic judgment of which group or sponsor is responsible for an intrusion, based on infrastructure overlap, tooling, targeting, and timing, usually expressed with explicit confidence levels rather than certainty.
- Threat Hunting
- Related: Indicators of Attack, Behavioral Analytics, MITRE ATT&CK
A proactive, hypothesis-driven search through telemetry for adversary activity that existing detections missed, ending with new detections, tuning, or a documented conclusion that no activity was found.
- Behavioral Analytics
- Related: Threat Hunting, Indicators of Attack, Baseline
Detection methods that model normal patterns of user, host, or network activity and flag statistically unusual deviations, catching novel techniques that signature matching cannot recognize.
- Baseline
- Related: Behavioral Analytics, Anomaly Detection, NetFlow
A recorded reference state of expected system, network, or user behavior gathered over a defined period, against which later activity is compared to identify meaningful deviation.
- Anomaly Detection
- Related: Baseline, False Positive, Behavioral Analytics
A technique that flags observations deviating from an established model of normal behavior, trading higher sensitivity to unknown threats for a greater volume of benign findings to investigate.
- False Positive
- Related: Alert Triage, Anomaly Detection, Detection Tuning
An alert raised on activity that is actually benign, which consumes analyst time and erodes trust in detection tooling when not tuned out.
- Detection Tuning
- Related: False Positive, Sigma Rule, Alert Triage
The iterative adjustment of rule logic, thresholds, and exclusions to reduce false positives and false negatives while preserving coverage of the behaviors a detection was written to catch.
- Alert Triage
- Related: Confidence and Severity Scoring, False Positive, Incident Response Lifecycle
The first-pass review of an alert to determine whether it represents real malicious activity, its scope and severity, and whether it should be escalated, closed as benign, or investigated further.
- SIEM
- Related: Log Normalization, Correlation Rule, SOAR
A platform that collects logs from many sources, normalizes and correlates them against rules, and surfaces alerts and dashboards, serving as the central console for monitoring and investigation.
- SOAR
- Related: Playbook, SIEM, Containment
A tooling category that executes automated playbooks for enrichment, notification, and containment, reducing manual steps in alert handling and enforcing consistent response actions.
- Log Normalization
- Related: SIEM, Correlation Rule, NetFlow
The conversion of heterogeneous log formats into a common schema with consistent field names and value types, enabling correlation and search across sources in a SIEM.
- Correlation Rule
- Related: SIEM, Log Normalization, Sigma Rule
Logic that combines multiple events across sources or time windows to detect a pattern, such as repeated failed logins followed by a success, that no single event reveals alone.
- Sigma Rule
- Related: Detection Tuning, Correlation Rule, YARA Rule
A vendor-neutral, YAML-based format for describing log-based detection logic that can be converted into queries for many SIEM and EDR platforms, supporting portable and shareable detections.
- YARA Rule
- Related: Indicators of Compromise, Sigma Rule, Malware Sandboxing
A pattern-matching rule, built from strings and conditions, used to identify and classify malware samples and suspicious files during scanning or forensic review.
- EDR
- Related: Process Tree Analysis, Containment, Living off the Land
Endpoint software that continuously records process, file, registry, and network telemetry, applies behavioral detections, and offers response actions such as isolating a host or killing a process.
- NetFlow
- Related: Beaconing, Network Traffic Analysis, Baseline
Summarized metadata about network connections, including source, destination, ports, byte counts, and timestamps, useful for spotting beaconing, data transfer, and lateral movement without full packet capture.
- Network Traffic Analysis
- Related: NetFlow, Beaconing, Command and Control
The inspection of packet captures and flow records to identify malicious communication, protocol abuse, exfiltration, and command-and-control channels that endpoint tools may not observe.
- Beaconing
- Related: Command and Control, NetFlow, Network Traffic Analysis
Regular, periodic outbound connections from an infected host to attacker infrastructure, whose consistent timing and small repeated payloads are a strong signal of remote access malware.
- Command and Control
- Related: Beaconing, Living off the Land, Cyber Kill Chain
The channel an attacker uses to send instructions to and receive results from compromised hosts, often disguised as normal web, DNS, or cloud traffic to blend into the environment.
- Living off the Land
- Related: Command and Control, Process Tree Analysis, EDR
An adversary approach that abuses legitimate built-in tools such as PowerShell, WMI, or certutil instead of dropping custom malware, making activity harder to distinguish from administration.
- Lateral Movement
- Related: Privilege Escalation, Process Tree Analysis, Cyber Kill Chain
Techniques an attacker uses to move from one compromised host to others, such as remote service creation or credential reuse, expanding access toward high-value targets.
- Privilege Escalation
- Related: Lateral Movement, Persistence, Cyber Kill Chain
The step in which an attacker gains higher permissions than initially obtained, through credential theft, misconfiguration abuse, or exploitation, to reach protected data and systems.
- Persistence
- Related: Eradication, Lateral Movement, Cyber Kill Chain
Mechanisms an attacker installs so access survives reboots, credential changes, or cleanup, such as scheduled tasks, services, or startup entries that must be found and removed during response.
- Process Tree Analysis
- Related: EDR, Living off the Land, Lateral Movement
Examining the parent-child relationships and command-line arguments of running processes to spot suspicious lineage, such as a word processor spawning a scripting interpreter.
- Malware Sandboxing

- Related: Containment, Persistence, Recovery
The response phase that removes the root cause of an incident, including malware, persistence mechanisms, and exploited vulnerabilities, so the threat cannot simply resume.
- Recovery
- Related: Eradication, Lessons Learned, Incident Response Lifecycle
The response phase that restores affected systems and services to normal operation, validates that they are clean, and monitors closely for signs of reinfection before returning to steady state.
- Lessons Learned
- Related: Incident Response Lifecycle, Playbook, Detection Tuning
A post-incident review that documents what happened, what worked, and what failed, producing concrete changes to detections, playbooks, and controls rather than a narrative report alone.
