The Waikato Cyber Security Research Group (CROW)

What we do

Cyber security (or simply systems security) is the practice of protecting systems, networks, and data from digital attacks, unauthorised access, damage, or theft. It involves implementing technologies, processes, and controls to secure access to information and services, ensuring its confidentiality, integrity, and availability. Cyber security is cross-sectional to computer science, ranging from hardware security to social engineering techniques.

Our group, Cybersecurity Researchers of Waikato (CROW), tackles pressing research problems and covers some of the most relevant areas in Cybersecurity, such as (alphabetical order):

Research areas

Applied cryptography
Honeypots, IDSes, and active sensing for attack characterisation
Cyber deception
Data provenance and sovereignty
Distributed Denial-of-Service (DDoS) attack and mitigation
Industrial Cyber-Physical Systems (ICPS) Security
Industrial Internet of Things (IIoT) Security
Internet measurements and experimentation
Internet scanning and network security assessment
Machine Learning Approaches for Cybersecurity
Malware Analysis and Detection, including Ransomware
Privacy in Vehicular Ad Hoc Networks (VANETs)
Routing security
Software-defined networks (programmable data planes) for Network Security

Papers and courses

The key research group personnel is four faculty with expertise on the topics previously, complemented by a strong team of Research Programmers, PhD students, Master of Cybersecurity (MCS) students, and Honours students.

Our team expertise supports a range of cyber security papers/courses at all levels, including:

Our infrastructure

The infrastructure of our research group includes a spacious lab space regularly attended by the team, a powerful server to crunch large datasets (e.g. network traces and system logs), and a cluster of 40+ Internet-facing machines that we use for experimentation and measurements, including in demonstrations and practical work part of our lectures.

Community and partnerships

Since 2014, we have organised the NZ Cybersecurity Challenge, helping to spark interest in Cybersecurity in young students as well as provide a forum for the discussion of cybersecurity trends in NZ. It has attracted a large number of students every year, of all levels, industry participants, and sponsors, which help us grant awards for the winners.

Together with New Zealand industry partners, multi-national companies and international consortia, we work on discovering and disclosing vulnerabilities that expose user data to dangers in both systems and networks.

Our people

Associate Professor Marinho Barcellos
Senior Lecturer, Programme Lead Computer Science

Since October 2019 I have been with the University of Waikato. In the past, I worked at INF/UFRGS Federal University (Associate Professor, 2010–2019), UNISINOS University (Adjunct Professor, 1993–2008), PUC-RS University (2008–2009), as well as an Invited Adjunct Professor at UNAL, Colombia.

I have regularly contributed to the network research community by serving in multiple committees. I was the general co-chair of ACM SIGCOMM 2016 and have been serving as Program Committee co-chair of ACM CoNEXT 2022. I have contributed as a member of several Technical Program Committees of conferences: ACM CoNEXT, IEEE INFOCOM, IEEE ICNP, ACM HotNets, ACM IMC, IFIP Networking, etc. I was a member of the ACM SIGCOMM Executive Committee 2017-2021, and have been a co-chair of the ACM SIGCOMM CARES committee. I also contributed as a member of the steering committees of ACM CoNEXT and the PAM conference, and chairing the Advisory Board of the ACM PACM-NET journal.

I am fortunate to have supervised many bright students (and hope some new ones look for me in the future). Contact me if you are interested, but to be sure I am a good fit for you, please first read my recent papers and be ready to talk about the ones that interested you: it’s a proof-of-work without which you may not get a response :) If you are unaware of my work, I may not respond to your email.

Dr Vimal Kumar
Senior Lecturer

I studied Computer Science & Engineering at IP University in New Delhi before working for a couple of years with Computer Sciences Corporation in India. I moved to Missouri, US in 2008 for further study, where I worked on various problems surrounding secure data aggregation in sensor networks with Prof. Sanjay Madria. I received a PhD in Computer Science from the Missouri University of Science & Technology in 2014. My first academic position was with the University of West Florida in Pensacola after which I moved to University of Waikato in mid 2015, where I have been since, first as a Lecturer and then as a Senior Lecturer from 2020.

Notice regarding NZCSC 2021:
After the culmination of NZCSC'21 it was brought to our attention that some challenges were plagiarized from sources on the internet. The NZCSC organisers reported this to the employer of the person who created and submitted the challenges to be used in NZCSC. The employer took swift and strictest possible action for the misconduct. The NZCSC values integrity above everything else and the team was deeply saddened with the discovery. We apologise to all NZCSC'21 participants for this oversight and assure everyone that we have now put measures in place to ensure this does not happen again.

WHAT HAPPENED?

The NZ Cyber Security Challenge 2018 (NZCSC'18) hovered into action with a drone challenge for Round 1 & 2 contestants at the University of Waikato campus. Challengers tested their hacking skills as they attempted to take charge of a drone controlled by a host's smartphone and intercept photos taken by the drone's camera. Prizes were awarded to the successful hackers. NZCSC'18 action also included training sessions with some of the best, opportunities to kickstart a cyber security career at the job fair and talks by some of the movers and shakers in the industry. Round 0 online qualifying round took place from June 18-29, with the top 150 moving on to Rounds 1 and 2 on July 14 at the University.

CSC 2017

FIRST PLACE

2017 challenge known for Challenge Winner Repeat Performance .
It was a repeat performance by the overall champions team Arcton, Nathaniel Watson, Jeremy Symon and Grady Hooker took out last year's Challenge.

Representing industry, they walked away with a cheque for $2500 and NetHui fellowships. Jeremy is currently doing a Masters of Computer Science at Waikato and working at Gallagher, and Grady and Nathaniel are former Waikato Computer Science students now working in the computer science industry.

RUNNERS UP

Overall runners-up 418ShortAndStout - Michael Robertson and Brent Vollebregt - placed top in the tertiary division and took home $1800.

Top performers in the high school division after Rounds 1 and 2, SQL Sharks twins Sam and Josh Hogan also took out first place in the new Policy Round. Contestants were tested on responsible disclosures, asked to critique a really badly-written cyber policy, and suggest incident response next steps for a fictitious event.

The winning team from the industry division after Rounds 1 and 2 were Jack Haystead, Daniel Tebbutt and Declan ter Veer-Burke. They took home a cheque for $1800.

WHAT HAPPENED?

NZCSC'17 hit all the right keys with VIPs from the Government Communications Security Bureau (GCSB) and INTERPOL attending. GCSB director Andrew Hampton told the Challengers it wasn't long ago that people were saying cyber security should be on the agenda but now the agenda is cyber security.

Although, In this year's Challenge CROW collaborated with Japan's National Institute of Communications and Information Technology ( NICT ) to up the ante in the visualisation of the attack and defend networks of the competition. CROW member Cameron Brown worked with Koei Suzuki to customise the NIRVANA Kai visualisation to show network traffic between the Round 3 servers. The collaboration is mutually beneficial as NICT will utilise CROW technology in the future. NICT supply the visualisations for Japan's largest cyber security competition SECCON.

NZCSC'15 was open to all of New Zealand and participants were split into 3 categories: Secondary, Tertiary, and Industry/Open.

The competition had 2 rounds: Round 1 was a capture-the-flag style challenge. Round 2, open to the top 5 teams of Round 1, was a Red team vs. Blue team style challenge where 5 Blue teams defended their systems against the Red team, which included Industry professionals from Insomnia Security and PWC Digital.

CSC 2014

The first instalment of the Cyber Security Challenge was open to University of Waikato students only.

CSC'14 had a single round - a capture-the-flag style challenge where the students participants solved challenges to acquire flags. The event served its purpose: to gauge students' interest in a Cyber Security-themed competition. Over 70 students registered, attended the training and paticipated in the competition, which encouraged the organisers to plan the next CSC.
