Skill Profile
Threat Detection & Analysis
"The observable action of monitoring system logs, network traffic, and security alerts to identify indicators of compromise or malicious activity — correlating events across data sources, distinguishing genuine threats from false positives, and escalating confirmed incidents for containment and response."
YOUR SKILLS
Problems This Skill Solves
- Breaches that go undetected for months because no one is actively monitoring for signs of intrusion — systematic threat detection reduces dwell time (the period between initial compromise and detection) which is the primary driver of breach severity.
- Alert fatigue that causes genuine threats to be missed — applying triage and correlation logic to thousands of daily alerts prioritises the genuine threats requiring investigation from the noise of routine false positives.
- Insider threats and compromised credentials going undetected — user and entity behaviour analytics (UEBA) identifies anomalous behaviour patterns that indicate account compromise or malicious insider activity.
- Post-incident analysis that cannot reconstruct the attack chain — systematic log collection and retention means forensic investigators can reconstruct the timeline and method of an attack for lessons learned and legal purposes.

Cybersecurity / Technology / Finance
"If you have a SIEM, you have threat detection covered — the tool does the work."
A SIEM is a data aggregation and correlation platform — it produces the alerts that trained analysts investigate. Without skilled analysts writing effective detection rules, triaging alerts accurately, and investigating confirmed threats correctly, a SIEM generates noise rather than intelligence. The most expensive SIEM implementation with no skilled analysts is less effective than a modest tool operated by a capable team.
Research & Outlook
AI and machine learning are improving detection accuracy — reducing false positive rates and identifying subtle anomaly patterns that rule-based detection misses. Automated SOAR (Security Orchestration, Automation and Response) platforms are handling tier-1 alert triage at machine speed, shifting human analysts towards investigation, hunting, and detection engineering. The volume and sophistication of threats continues to increase, maintaining strong demand for skilled threat detection professionals despite automation.

Growth Path
Monitors a SIEM dashboard and triages incoming alerts against defined playbooks. Distinguishes known false positive patterns from genuine threats. Escalates confirmed incidents to Tier 2 analysts with a clear summary of the evidence. Understands the MITRE ATT&CK framework at a conceptual level.
Investigates complex multi-stage attacks across endpoint, network, and identity data sources. Writes and tunes SIEM detection rules to improve signal quality. Uses threat intelligence to contextualise alerts with actor attribution and campaign context. Contributes to post-incident analysis and detection improvement. Conducts threat hunting exercises to proactively search for undetected threats.
Designs the detection architecture for a SOC — selecting tools, building the data pipeline, defining detection priorities aligned to the organisation's threat model, and establishing the operating procedures. Leads threat hunting programmes. Develops custom detection logic for advanced persistent threats targeting the organisation's sector. Contributes threat intelligence to industry sharing communities (ISACs).
How to Practise
- 1.Set up a home lab SIEM (using the free tiers of Elastic SIEM or Microsoft Sentinel) and ingest logs from a virtual machine — practise writing detection rules for common attack techniques and investigating the alerts they generate.
- 2.Work through MITRE ATT&CK tactics systematically — for each tactic (Initial Access, Execution, Persistence...) understand what attacker behaviour looks like, what logs would capture it, and what a detection rule would look like.
- 3.Complete CTF (Capture the Flag) competitions and platforms (TryHackMe, HackTheBox, Blue Team Labs Online) — these provide realistic threat detection and investigation scenarios with guided learning paths.
- 4.Practise log analysis: take a sample of Windows event logs, Linux auth logs, or web server access logs and manually identify anomalous entries that could indicate attack activity.
