About Me
I am a Cyber Security Analyst at Temika Cyber, focused on Blue Team operations, security monitoring, threat detection, and incident investigation. My work involves analyzing security alerts, investigating suspicious activities, correlating events across security telemetry, and supporting incident response to help organizations identify and respond to potential threats.
Previously, I worked as an Endpoint Security Engineer supporting PT Bank Negara Indonesia (Persero), Tbk., where I managed and maintained enterprise endpoint security solutions across Windows, macOS, and Linux environments. I gained hands-on experience with EDR, DLP, and NAC technologies, endpoint and server hardening, security policy enforcement, troubleshooting, and remediation. This experience gave me a strong understanding of how defensive security is implemented and operated in a large enterprise environment.ments.
My technical foundation extends beyond endpoint security. I have a strong understanding of networking and security fundamentals, including TCP/IP, OSI layers, routing, switching, NAT, VPN, LAN/WAN, network architecture, and common attack patterns. I have also worked with SIEM platforms such as IBM QRadar, endpoint security platforms including CrowdStrike, Cortex XDR, and Cybereason, as well as threat intelligence and threat hunting activities
