As a Cyber Security Analyst, I was responsible for identifying, analyzing, and mitigating potential cyber threats targeting enterprise systems and networks. My daily responsibilities included monitoring SIEM dashboards, analyzing logs, investigating security incidents, and coordinating responses to minimize risk and downtime.

I conducted regular vulnerability assessments and worked closely with the IT and DevOps teams to implement security best practices, patch critical systems, and harden environments against attack vectors. I also developed detection rules and response playbooks to enhance the SOC’s efficiency.

Key technologies used: Splunk, Wazuh, ELK Stack, Nessus, Nmap, CrowdStrike, Windows Event Logs, and MITRE ATT&CK framework.

As a Network Security Engineer, I was responsible for designing, implementing, and maintaining secure network infrastructures. I worked extensively with firewalls, VPNs, intrusion detection/prevention systems (IDS/IPS), and network access controls to protect sensitive data and ensure business continuity.

My role involved continuous monitoring of threats, performing risk assessments, configuring security appliances, and collaborating with IT and compliance teams to enforce security policies. I also participated in security audits and incident response planning.

Key tools and technologies I used include: Fortinet, Cisco ASA, Palo Alto, Wireshark, and Splunk.
