What I'm looking for

I'm looking to strengthen organizational security posture through hands-on security monitoring, incident response, vulnerability management, endpoint security, cybersecurity governance, and continuous learning.

At LCB Finance PLC, I support security monitoring, vulnerability management, endpoint protection, incident response, compliance, and policy implementation in a financial-sector environment.

I investigate security events through SIEM, endpoint security tools, log management, and Windows Event Logs. I also contribute to PAM and DLP operations, firewall policy reviews, audits, risk assessments, vendor reviews, and employee security-awareness training.

Previously, as a NOC Intern at the Information and Communication Technology Agency of Sri Lanka, I monitored and responded to LGN2 incidents and supported secure network, cloud, DNS, wireless, and government-hosted infrastructure operations. I worked with F5 Web Application Firewall monitoring, SSL certificate renewal, patch management, access control, and infrastructure documentation.

I'm focused on strengthening organizational security posture through practical monitoring, secure operations, cybersecurity governance, and continuous learning. My technical interests include SIEM operations, endpoint security, PAM, DLP, network security, and protecting critical digital services.
