- Monitor and investigate potential security threats using tools such as Kibana/OpenSearch and Snowflake.
- Analyze security logs and investigate suspicious or unusual activity, including spikes in traffic, unexpected changes in attack patterns, and new or disappearing attack signals.
- Determine whether detected activity is malicious or benign and identify the appropriate response, including detection engineering to block malicious activity when needed.
- Develop, tune, and deploy detection rules based on traffic behavior, HTTP request attributes, headers, device fingerprints, and other indicators to mitigate malicious activity.
- Monitor existing detections and known attack patterns to make sure they continue to work as expected and identify any unusual changes in volume, sources, IPs, domains, or other indicators.
- Support customer onboarding by analyzing web application traffic flows and configuring baseline detection and protection rules.
- Investigate customer-reported incidents and missed detections, analyze attack traffic, and implement mitigations to improve protection coverage.
- Document newly discovered threats and attacks, including evidence, findings, and indicators.
- Communicate findings to Engineering and other stakeholders and provide the necessary technical details to support remediation and improvements to detection and protection mechanisms.
- Partner directly with counterparts through a ticketing system and support portal to investigate issues, provide updates, and resolve security-related requests.
