Creating a safer digital environment

In an era where cybersecurity threats are constantly evolving, Dr Maryam Varnaseri is committed to making a significant contribution to the cybersecurity field after graduation.

By proactively detecting cyber-attacks, Maryam hopes to not only catch hackers in the act but also to learn from them and predict their next moves.

Interested in the complex nature of cybersecurity, Maryam first completed a Master’s degree in information assurance at the University of Technology Malaysia. The opportunity to develop critical thinking skills, contribute to impactful research, and collaborate with supportive peers and mentors made it a no-brainer for Maryam to pursue postgraduate study.

“My decision was driven by a clear understanding of the role that advanced education plays in achieving professional excellence and leadership in the tech industry. Tackling the most pressing cybersecurity challenges requires not just technical skills but a nuanced understanding of the strategies and technologies at the cutting edge of the field. Postgraduate study offered me the opportunity to immerse myself in research that has the potential to shape the future of cybersecurity practices and policies.”

Having recently completed her PhD at Te Herenga Waka—Victoria University of Wellington, Maryam has dedicated her research to improving deception systems called honeypots, which act as a trap to detect and deceive cybercriminals. Her research focused on integrating advanced technologies into these deception systems to make them smarter and more adaptive, in the hope that computer systems will be able to learn from hackers and prevent future attacks. To achieve this, Maryam used a system called Cowrie.

“Cowrie acts like a decoy, mimicking vulnerable parts of a computer network to attract attackers. The addition of AI and Reinforcement Learning—an agent that teaches software to make decisions—allows this system to adapt to the attacker's methods in real time, leading to a more extended interaction. This way, we can learn more about their techniques and strategies.

“My research has shown promising results. By using smarter technology to stay several steps ahead of cybercriminals, we’re getting better at understanding how they operate. This proactive approach to cybersecurity could significantly reduce the damage caused by cyberattacks and make the internet a safer place for all of us.”

Having witnessed the destructive effects of cyberattacks firsthand, Maryam emphasises that the importance of enhancing cybersecurity systems cannot be overstated. As we become more reliant on digital technology, the threat of cyberattacks can impose risks to individual privacy, corporate assets, and even national security.

“The benefits of this work are far-reaching. For individuals, it means better protection of their personal information online. For companies, it translates into safeguarding their data and operations from cyber threats. On a national level, it helps protect important infrastructure, which is vital for maintaining economic and social stability.”

Initially attracted to the University’s renowned research capabilities and emphasis on innovation, Marayam says she is grateful for the support she received from her supervisors, Associate Professor Ian Welch, Dr Masood Mansoori, and Dr Harith Al-Saha.

“What truly set me on this specific path was my supervisors' extensive knowledge and passion. Their expertise in the field inspired me to explore how these cybersecurity systems could be enhanced to outwit attackers more effectively.

“Through seminars, workshops, and conferences, I've had the chance to learn from and interact with professionals and academics whose insights have profoundly influenced my perspective and research direction. It's through collaborations like these that great strides in research are made, and I am proud to be part of such a dynamic and supportive community.”

As for her future aspirations, Maryam hopes to make a significant contribution to the cybersecurity field. She plans to either join the tech industry, follow an academic career, or pursue roles within the public sector.

“Regardless of the path I choose, I'm committed to lifelong learning and collaboration. The field of cybersecurity is rapidly evolving, and staying updated with the latest research, technologies, and strategies will be key to my ongoing success and impact.”
