The competition was held at the university's premises on Wednesday and required participants to present fresh ideas on cyber security.
A statement from Kaspersky said Tam made a presentation on cyber security in small business for which she received the top prize of $1000.
Said Tam: "I am pleasantly surprised to win this challenge. I believe I can help small businesses start their journey to build a cyber security posture.
RMIT University cyber security design manager Prapurna Uppuluri, who was on the judging panel, said: "Tracy’s idea was very clear in addressing current problems small businesses face in cyber security. We believe her project can help small businesses in the future and with the right approach, her idea will allow for positive legislative change.

The other judges were Dr Joanne Hall, RMIT lecturer in Mathematical Sciences; Kaspersky senior security researcher Noushin Shabab; and Kaspersky ANZ general manager Margrith Appleby.
The runners-up prize, a sum of $500, went to a group of cyber security and data science students who outlined risk management controls with a machine learning implementation to predict student performance in educational institutions.
The judges were said to have been impressed by the team’s timely predictions of student performance which would then help tutors allocate the right resources for those needing further academic help.
Dr Hall, who was behind the idea, said: "Our students are going to go out to make the world a better place, so we need to invite the world into universities.
"We hope to explore opportunities to work with more industry partners in cyber security."
Next year, Kaspersky plans to encourage more students to take part in its internationally recognised Secur'IT Cup competition. The winner of this competition gets US$10,000 and an invitation to the annual Kaspersky Security Analyst Summit.
