Raja Sekar A

I am a computer science engineer with hands-on experience in network engineering and cybersecurity, specializing in securing LAN/WAN environments and conducting threat analysis and penetration testing. I have practical exposure to configuring routers, switches, firewalls, and common network services such as DHCP, DNS, NAT, and VLANs.

I have used security tools including Wireshark, Nmap, Metasploit, and worked with SIEM, EDR, IDS/IPS platforms, applying best practices in access control and incident-aware monitoring during internships and projects. My academic project on Forensic Data Encryption implemented strong encryption, auditable key management, and role-based controls to preserve evidence integrity while enabling authorized forensic access.

I hold a B.Tech in Computer Science and am eager to apply my skills to protect organizational IT assets, grow in hands-on cybersecurity roles, and contribute to defensive security operations and secure network design.
