• Collaborate with security operations teams to investigate suspicious activity and support incident triage and escalation.
• Analyse network traffic at the packet level to identify potential threats and malicious behaviours.
• Configure and maintain network traffic capture and mirroring solutions including taps and packet brokers.
• Validate and deploy new signatures, behavioural detection rules, and platform updates across IDS and IPS systems.
• Monitor platform health, performance, and capacity to ensure reliable detection coverage across the network environment.
• Develop detection logic based on threat intelligence, indicators of compromise, and emerging attack techniques.
• Document tuning decisions, configuration changes, and detection improvements to support operational traceability.
