Day-to-Day Responsibilities
Form hypotheses about how attackers could be getting in, based on current threat intelligence and the organisation's own systems.
Search endpoint, network and log data for signs of intrusion, such as unusual logins, odd outbound traffic or persistence mechanisms.
Analyse suspicious files, scripts and running processes to understand what an attacker did and how they did it.
Use SIEM platforms, endpoint detection and response (EDR) tools and network analysis software to write and run queries.
Map findings to frameworks such as MITRE ATT&CK so that gaps in detection can be identified and closed.
Turn confirmed threats into new detection rules and playbooks shared with the SOC and incident response teams.
Write clear reports for technical teams and non-technical leaders on what was found, its impact and what to fix.
