Personal profile


Professor Sezer is the Director of Research and the Head of the Networked System Security at the Centre for Secure Information Technology (CSIT). He is a world-renowned authority in high-performance network processing and Internet security technologies. His research is leading major advances in the field of high-performance content and security processing, spanning cybersecurity related topics in malware, embedded systems, IoT, ICS and network security, in collaboration with leading corporations in the US and UK.   Professor Sezer is also co-founder and CTO of Titan IC Systems Ltd, and is a member of various research and executive committees.

Research Statement

Research targets various aspects of information and network security technologies. The main focus has been the acceleration of network security related functions by exploring novel hardware based parallel processing architectures, System on Chip (SoC), NPU/NFP (Netronome) and programmable technologies, including MPSoC and FPGA. Most of my research projects are funded by a number of research funding bodies including EPSRC, ESRC, FP7, Innovate UK, InvestNI, and Industry. The broader topic of active research projects include:

  • High-performance parallel network traffic and content analysis circuits and processing architectures

  • Mobile security, Android malware analysis and detection methods based on static analysis and machine learning algorithms

  • Industrial Control and Critical Infrastructure protection (protection of networked ICS / SCADA Security, SCADA specific IDS/IPS)

  • Software Defined Networking and Virtual Network Function (SDN/VNF) security

  • Cloud security surrounding the security of cloud client applications, virtual security appliances and the security of cloud infrastructures

  • Host based and Cloud based malware analysis and real-time threat detection and mitigation technologies (Ransomware, Bots, APT)

  • Network based detection of Advanced Persistent Threats (APT)

  • Real-time detection, mitigation/prevention technologies for various forms of cyberattacks, including Application Layer DDoS attacks, intrusion-based attacks, SQL injection, etc..

  • IoT device security and IoT security policy monitoring and enforcement technologies.

Research output in high-performance network security processing led to the development of the world's fastest content (RegEx) processor for inspecting Internet traffic at 100Gbit/s. Research output, competencies and know-how in IP packet and flow classification led to multimillion dollar research contracts with industry and the transfer of technology. International research collaboration with ETRI and Hanyang University in Korea led to numerous key research outputs in malware detection and produced new cybersecurity technology tailored for highly virtualised Cloud Computing Services. Underpinning innovations in IP traffic feature extraction and classification combined with highly optimised machine learning algorithms are core research skills and capabilities defining the research output and research projects.
