Cybersecurity Operations & Incident Response Intern

About the Role

We are looking for a Cybersecurity Operations & Incident Response Intern to join our security team and gain hands-on experience in Security Operations Centre (SOC) activities, threat detection, alert investigation, incident response, and digital forensics.

This internship is designed for candidates who want to build practical cybersecurity skills by working with security telemetry, investigating alerts, analysing suspicious activity, developing detections, and supporting incident response activities.

The role provides exposure to industry-standard cybersecurity tools and methodologies, including SIEM platforms, MITRE ATT&CK;, Sigma, threat intelligence, endpoint telemetry, network monitoring, cloud security, and forensic investigation .

Key Responsibilities

- Monitor and analyse security alerts from SIEM and security monitoring platforms.
- Perform initial alert triage and determine whether activity is benign, suspicious, or malicious.
- Investigate security events using endpoint, network, identity, and cloud telemetry.
- Search and correlate security data using platforms such as Splunk, Elastic, and Microsoft Sentinel .
- Document investigation findings, evidence, severity, impact, and recommended actions.
- Assist with incident response activities, including identification, containment, eradication, and recovery.
- Map observed attacker behaviour to the MITRE ATT&CK; framework.
- Assist in creating, testing, and tuning security detection rules using Sigma and other detection technologies.
- Participate in threat-hunting exercises based on defined hypotheses and available security telemetry.
- Support digital forensic investigations involving Windows systems, disk evidence, memory evidence, and relevant system artefacts.




- Assist with analysing cloud and identity security events, including Microsoft Entra ID and AWS CloudTrail logs.
- Contribute to incident timelines, investigation reports, shift handover notes, and executive-level summaries.
- Participate in purple-team and simulated incident exercises.
- Help identify opportunities to improve detection coverage, reduce false positives, and strengthen security monitoring.
- Maintain accurate documentation of investigations and follow established security procedures.

Tools & Technologies During the internship, you may work with technologies including:

- SIEM: Splunk, Elastic Stack/Kibana, Microsoft Sentinel
- Endpoint & Network: Sysmon, Windows Event Logs, Zeek, Suricata, Wireshark
- Detection: Sigma, MITRE ATT&CK;, ATT&CK; Navigator
- Forensics: Velociraptor, Volatility 3, KAPE, Plaso, Timesketch
- Threat Intelligence: MISP, STIX/TAXII
- Incident Management: TheHive, Cortex
- Automation: Shuffle / SOAR technologies
- Cloud & Identity: AWS CloudTrail, Microsoft Entra ID
- Security Testing: Atomic Red Team

These technologies are aligned with the practical cybersecurity operations curriculum provided for the role.

What You Will Learn

By the end of the internship, the intern should be able to:
- Understand how a SOC operates and how security events progress from event → alert → investigation → incident → resolution .
- Analyse and correlate security logs from multiple sources.
- Conduct structured alert investigations using evidence rather than assumptions.
- Write transparent and defensible investigation notes.
- Apply MITRE ATT&CK; to real-world attack activity.
- Develop and tune basic detection rules.
- Understand the NIST incident response lifecycle .
- Support incident containment and investigation activities.
- Perform introductory host, disk, and me
