Chuck Brooks

Co-founder and CEO, Brooks Consulting International

Chuck Brooks has more than 25 years of experience in cyber security, technology, and government relations, over the course of a career that has led him to form his own consultancy firm and teach courses in homeland security and cyber security at Georgetown University in Washington DC.

As a consultant, his clients have included Fortune 1000 companies, governments and even the Vatican (the Pope’s headquarters are not immune to cyber risk), and he has received presidential appointments for executive service by two US Presidents.

Brooks is regularly named as a top cyber security expert to follow by trade press, and he contributes to a number of publications including Forbes, the Washington Post, Homeland Security Today and The Hill.

“In reflecting over the span of my career in security government and in the private sector, I have come to a recognition that there are several valuable elements for reaching you career goals,” Brooks told us. “These include: 1) being able to network and build relationships; 2) having the ability to effectively write and speak; and 3) to be able to dedicate yourself to learning and developing an expertise on key issues, concepts, and policies encompassing your work.”

Dr Blake Curtis

Senior technical program manager, security assurance, Amazon

As a research scientist specializing in quantitative correlational research, Dr Blake Curtis focuses on identifying the knowledge and abilities that lead to superior performance for cyber security professionals.

He gained great acclaim with The Next Generation Cybersecurity Auditor, a study that revealed the gap between the theoretical knowledge and practical skills of auditors working at the Big Four. One of his key findings was that task-based experience holds greater objectivity than length of experience.

In addition, Curtis is a specialist in creating global information assurance programs for government, commercial and healthcare sectors. He has led security and compliance at Vanderbilt University and Cigna, before moving to Deloitte where he eventually became global cyber security strategy and program manager. Most recently he has taken on the role of senior technical program manager in security assurance at Amazon.

He sees the greatest challenges for 2024 as being promoting digital trust, objectively assessing technical competence and creating governance and risk management practices for emerging technologies. “Notably, our industry will need an objective way to ensure we’re hiring professionals with the appropriate levels of task-based experience and removing barriers from hiring and promotion practices like mandating arbitrary years of experience to address our industry-wide skills shortage,” he says.

Kirsten Davies

CISO, Unilever

As the global chief information security officer (CISO) for one of the largest companies in the world, Kirsten Davies has her work cut out. However even before her appointment to Unilever in 2021, Davies had amassed a wealth of experience in her roles as CISO at Estée Lauder, Barclays Africa Group, Hewlett-Packard and Siemens.

She has led transformative projects at these organizations, including establishing a security academy at Barclays which re-skilled people to enter the cyber security sector, and achieving a landmark cyber security agreement with the German Workers Council that is now replicated across Hewlett Packard’s other work councils across EMEA.

She is on the advisory council of NYU’s Tandon School of Engineering, and is passionate about diversity and inclusion – her cosmetovigilance and Data Integrity Program at Estee Lauder beat cyber security and IT industry averages for the inclusion of individuals across genders, ethnicities, age and nationalities.

Parag Deodhar 

Managing director – global IT audit, Accenture

Parag Deodhar is part of the internal audit leadership team at Accenture based in Karnataka, India, where he is responsible for global technology and cyber-security assurance. He joined the company in 2022 after a stint as regional CISO for Asia Pacific at outdoor clothing company VF Corporation.

Before this he spent many years in the finance and insurance industries, working at AXA and Deutsche Bank. As a result he has accumulated more than 20 years of experience in enterprise risk management, operational risk, and fraud risk management, making him highly in-demand at conferences where he is invited to speak about fraud and cyber threats, particularly those emerging as a result of advancing technologies.

“The threat landscape will continue to evolve with the rapid adoption of new technologies like AI and ML by businesses, and also by adversaries to devise new attack vectors,” Deodhar told us. “The challenge for cyber security practitioners will be to help businesses adopt these technologies securely, by design and also keep defending against the new attack vectors.”

Lynn Dohm

Executive director, Women in Cybersecurity

Lynn Dohm has worked in various capacities in the cyber security education sector, holding the role of director of communications at the National CyberWatch Center, the Community College Cyber Summit and the National Cyber League.

In 2019 she joined Women in Cybersecurity (WiCyS) as executive director, which has since positioned itself as a leading model of how a multi-organizational approach can strengthen the cyber security workforce.

She has received numerous awards including the People’s Choice award for Cybersecurity Woman of the Year and has been named among the Top 100 Women in Cybersecurity by Cyber Defense Magazine.

Dohm is particularly passionate about diversity and inclusion, and how DEI policies can bridge the workforce gap and improve the recruitment, retention and advancement of women in cyber security. “One of the challenges continues to be the critical cyber security workforce shortage,” Dohm told us. “As technology increasingly intertwines with everyone’s day-to-day lives, the need for experienced cyber security professionals expands. Some reports expect it to grow 31 percent annually until 2029.

“While nonprofits like Women in CyberSecurity (WiCyS) continue building the pipeline for the cyber workforce, we must also focus on the leaky pipe. Inclusion within the workforce is essential for women and underrepresented individuals to know that they not only belong but can thrive and advance in lucrative cyber security careers because of it. That’s why the WiCyS mission to recruit, retain and advance women in cyber security is so important.”

Hardy recently say down with Cyber Security Hub to discuss how CISOs and their teams can navigate changing regulations. “First of all, I would say get a list of applications, do an inventory, and determine what’s out there,” he said. “Then what we want to take a look at is the area of operation, in what nations are these operating in, and in what state, etc? Because what we find out then is that where you are processing your data, where you are storing your data and where your customers are, are three different questions.”

Niel Harper 

Board director, ISACA

In this dual position she is responsible for leading and developing eSentire’s cyber resilience strategy and driving adoption of the company’s SaaS platform.

We asked Hopkins what threats to look out for in 2024. “I view the most imminent threat as more of a compounding effect – emerging technologies and rapid adoption, the cyber security skills gaps, and the constant evolution of threat and attack types. As we continue to rely more and more on interconnected systems, the opportunity for large-scale, multi-vector attacks only grows, and many organizations will struggle to keep pace.”

She adds: “Now more than ever it’s critical that security leaders focus on building programs and strategies that target organizational resilience as an outcome because simply managing risk is no longer enough.”

In addition to her day-to-day job, Hopkins is adjunct professor of cyber security at Katz School at Yeshiva University and a guest lecturer at the Wharton School. In 2020 she founded Empow(H)er Cybersecurity, a non-profit organization aimed at encouraging and supporting women of color to pursue cyber security careers.

Leading security policy at the world’s biggest cryptocurrency platform means Lau is well versed in getting ahead of emerging threats, so we asked him what he thinks the biggest challenge for cyber security will be next year.  “Undoubtedly the rapid and unpredictable advancements in AI,” he told us.  “While AI offers tremendous potential for enhancing our defense mechanisms, it also presents sophisticated attack vectors.

“Adversaries are leveraging AI to automate attacks, craft deceptive phishing campaigns, and bypass traditional security measures with alarming speed and precision. The dual-edged nature of AI means that while we can harness its power to bolster our defenses, we must also be perpetually prepared for its use in novel and increasingly sophisticated cyber attacks. The race between AI-driven defense and offense will define the cyber security landscape in 2024.”

Walls said the best professional advice he has had is to “be a coach in every situation. What is meant by that is, as an executive, your job is to inspire others to innovate. You don’t have to be the smartest person in the room, you should aspire to be the wisest and ask questions that help other people reach their own breakthrough outcomes.”

“Wise leaders know how to get people to give them 200 percent without ever having to ask for more than that first 100,” he adds. “Once you’ve got that 200 percent make sure your people are recognized and appreciated for their work and innovation. This creates a culture where the job feels more like a space to create and innovate than just a job. In cyber security this is especially important. The best practitioners are innovative in their approaches and steadfast in their desire to find new ways to protect and defend the organization.”
