A day in the life
A typical day for a Security Engineer may involve

Responding to new detections: Monitor security alerts in real-time, investigate suspicious activities by analysing logs and network traffic, determine if incidents are legitimate threats or false positives, and coordinate immediate response actions including containment and remediation when threats are confirmed.

Write security detections: Develop and implement custom detection rules based on emerging threat intelligence, tune existing security signatures to reduce false positives while maintaining coverage, and create automated alerts for specific attack patterns or indicators of compromise relevant to the organization's environment.

Threat hunt: Proactively search through network logs, endpoint data, and system activities for signs of advanced persistent threats that may have evaded automated detection systems, using threat intelligence feeds and behavioural analysis to identify potential security breaches before they cause significant damage.

Work with service teams on security issues: Collaborate with IT, network, and application teams to remediate identified vulnerabilities, coordinate security patches and system hardening efforts, provide security guidance during incident response, and ensure proper implementation of security controls across all infrastructure components.

Generate metrics and dashboards: Create and maintain security performance indicators including incident response times, threat detection rates, and system availability metrics, develop executive-level reports summarizing security posture and trends, and build real-time dashboards for continuous monitoring of security operations effectiveness.
