Cyber Defense Senior Analyst

Overview

As a Cyber Defense Senior Analyst, you will join the frontline of the Cyber Fusion Center, performing in-depth analysis, triage, and response to security threats by following documented policies, processes, and playbooks to meet Service Level Objectives (SLOs). The frontline team provides global 24x7 security operations and monitoring for cybersecurity events impacting Experian and is a division of Experian's Cyber Fusion Center (CFC) which is organized under the Experian Global Security Office (EGSO). It acts as the first line of defense in Experian's broader incident response and incident management functions and is responsible for receiving, triaging, and prioritizing cybersecurity alerts, including being the dedicated point of contact for potential security incidents reported by users (e.g., Experian employees). Depending on the results of triage, this team is then responsible for investigating, containing, eradicating, and recovering from events falling in its purview or escalating higher-risk events to dedicated incident response and management teams in the CFC as necessary.

This role is critical in ensuring the effective handling of potential threats and plays a part in driving continuous improvement in security operations.

• Maintain all case documentation, including notes, analysis findings, containment steps, and root cause for each assigned security incident. Ensure incident updates or contact with end users are performed in a timely manner and documented accordingly and that case hand-off processes are completed as appropriate, such as completing / verifying shift logs
• When requested, assist in training and onboarding of new team members to help their transition to our processes
