HUSSEIN SUDI LEMA
Biography
I am a Tanzanian ICT researcher specialising in VoIP security, with a focus on detecting and preventing Caller ID spoofing attacks. My work includes enhancing SIP communication through MAC address integration, and I have hands-on experience with network security, Linux administration, and managing FreePBX/Asterisk servers. I conduct live server experiments to evaluate detection accuracy and resource efficiency, aiming to develop practical solutions with national and global impact in secure communications.
Research Interest
My research interests focus on the intersection of network security, VoIP communication, and protocol enhancement, emphasizing the design and implementation of practical, resource-efficient solutions for real-world communication systems.

Publications
"Preventing IP Spoofing Attacks in a Shared Resources Network” was published in the International Journal of Cyber-Security and Digital Forensics in January 2019 (Vol. 8, Issue 2, pp. 144–151). The paper addresses the challenge of IP spoofing in shared network environments and proposes innovative methods to detect and prevent such attacks, contributing to enhanced network security and protection of shared resources.
“Security Enhancement of SIP Protocol in VoIP Communication” was published in the Journal of ICT Systems on December 29, 2023, through Independent Academia. The study focuses on strengthening the SIP protocol used in VoIP communications against vulnerabilities, aiming to enhance authentication and maintain the integrity of VoIP calls, aligning closely with research in secure real-time communication systems.
