Core Responsibilities

Primary Functions

Actively monitor and meticulously analyze security alerts originating from a diverse set of sources, including Security Information and Event Management (SIEM) systems, Intrusion Detection/Prevention Systems (IDS/IPS), and Endpoint Detection and Response (EDR) platforms.
Execute the initial triage and in-depth investigation of security events to rapidly determine their severity, scope, and potential business impact on the organization's network, systems, and data.
Systematically follow and execute established incident response playbooks for the containment, eradication, and recovery from confirmed security incidents such as malware outbreaks, sophisticated phishing campaigns, and unauthorized access attempts.
Conduct preliminary static and dynamic malware analysis on suspicious files, attachments, and executables to understand their behavior, extract indicators of compromise (IOCs), and assess their threat level.
Perform deep-dive analysis of raw data, including network traffic captures (PCAP), endpoint process logs, and other system data using tools like Wireshark and Splunk to meticulously trace the full lifecycle of a security incident.
Manage the security incident lifecycle by appropriately escalating complex or high-severity incidents to senior analysts, specialized response teams, or leadership according to predefined criteria.
Author detailed, high-quality incident reports and maintain comprehensive case documentation that clearly outlines the investigation process, key findings, actions taken, and concrete recommendations for future prevention.
Proactively identify, collect, and catalog Indicators of Compromise (such as malicious IP addresses, file hashes, and C2 domains) and feed them into threat intelligence platforms and security controls to bolster automated defenses.
Provide real-time, expert support and clear guidance to IT infrastructure teams and business end-users during security incidents to coordinate effective remediation and prevent further compromise.
Actively hunt for latent and emerging threats within the environment by developing and running custom queries and analytics against large-scale security datasets to uncover suspicious patterns and anomalous activity that evade traditional alerting.
Analyze and respond to phishing emails and other social engineering attempts reported by employees, using the findings to both educate users and enhance technical email security controls.
Participate in the continuous tuning, configuration, and optimization of security monitoring tools and systems to improve the fidelity of alerts, increase detection accuracy, and reduce false positives.
Operate as a key member of a 24/7 rotational shift schedule, ensuring that the Security Operations Center (SOC) maintains continuous, around-the-clock monitoring and response capabilities.
Conduct foundational digital forensics by properly preserving and analyzing evidence from compromised systems in a forensically sound manner to support deeper investigations and post-mortem analysis.
Maintain a sharp and current understanding of the latest cybersecurity threats, novel attack vectors, and critical vulnerabilities through continuous professional development, threat intelligence feeds, and industry publications.
Review and diligently assess security alerts from cloud environments (AWS, Azure, GCP), investigating potential service misconfigurations, unauthorized API access, and other cloud-native threats.

Secondary Functions

Support ad-hoc data requests and exploratory data analysis to assist senior analysts and threat hunters in more complex, long-term investigations.
Contribute to the organization's overarching security strategy by providing valuable frontline feedback on the real-world effectiveness of existing tools, policies, and procedures.
Collaborate with various IT and business units to translate security incident findings and operational needs into actionable engineering or policy requirements.
Participate actively in sprint planning, daily stand-ups, and retrospective meetings as a member of the agile cybersecurity team.
Assist in the development, review, and refinement of incident response playbooks, standard operating procedures (SOPs), and other critical technical documentation.
Participate in post-incident review meetings to help identify root causes and lessons learned, contributing directly to the continuous improvement of the security program.
Help mentor junior team members or interns by generously sharing knowledge, reviewing investigative work, and providing constructive guidance on SOC best practices and tradecraft.
Support the vulnerability management program by assisting in the validation, risk assessment, and prioritization of vulnerabilities identified by automated scanning tools.
