How can cybersecurity transform to accelerate value from AI?

Today, Secure Creators are integrating AI into their detection, response and recovery processes in new ways, allowing them to stay ahead of adversaries, who themselves are using AI attack methods unhindered by regulations or use policies.

By rapidly analyzing enterprise-scale data, AI can automatically detect different attack signatures and new attack methods. With the proper architecture, AI can plug into existing cyber approaches across IT and OT systems to detect incidents faster than people alone.

Advances in deep learning and neural networks now enable the parsing of larger and more heterogeneous datasets in real time. The ability to self-train and learn is accelerating automation, helping cyber teams continuously monitor networks and applications, detect and forecast threats in near real-time, and respond to incidents faster. Deep learning also improves cyber accuracy and efficiency. A meta-analysis of 69 research studies shows an average accuracy of over 92% in detecting spam, malware and network intrusions.²

Gajan Ananthapavan, Global Head of Security Operations, Intelligence and Influence at Australia and New Zealand Banking Group Limited (ANZ Bank), says around 30% of the organization’s incident response has been automated, thanks largely to ML and AI. “We ingest more than 10 billion data events each day as part of monitoring, detecting and responding to potential security events and incidents across our environment,” he said. “We wouldn't be able to manage that volume without ML and AI.”

A CISO at a large North American asset management firm says the company has cut its mean time to detect and respond by at least 50%. Data from the 2023 study shows that Secure Creators saved over 150 days on average detecting and responding to a data breach. 

AI helps cyber teams be more effective with the same or fewer resources, presenting an opportunity to satisfy the CFO by doing more with less. Early EY analysis points to efficiency gains from the use of AI in cyber defense that can range from 15% to 40%. To get the most efficiency gains, CISOs need to first ensure they reduce complexity and consolidate legacy cyber infrastructure. As the group CISO at Bupa notes, “You need to transform your tech stack before thinking about profiting with things like automation and GenAI. It doesn't make sense try to automate a broken process.”

Actions for CISOs:

• Expand the scope of automation: Produce a detailed audit of the cyber team’s automatable tasks and consider where people insight is best focused while ensuring attention to explainability and appropriate thresholds. Assess automation capabilities of third-party vendor products, prioritizing the implementation of functionality within vendor-partner software above custom automation use case.
• Consider the entire enterprise when evaluating AI for cybersecurity: This includes corporate environments, plants and field-level assets.
• Stay up to date on emerging applications of AI in threat detection and recovery: While not yet emerging in a meaningful way, EY topic clustering analysis shows threat detection and recovery are active areas of inquiry. Considerations should be given to applications in these areas, such as recovery planning, analysis of incident reports, and prevention of zero-day attacks.
• Follow the data: AI and ML investments are going to be most profitable where there is cyber data density. Focus on areas such as identity management, threat and vulnerability, and security operations where large-scale data is difficult to manage.
• Build for reuse: Certain functions will have broad applicability within cybersecurity and across the enterprise – avoid development and maintenance duplication by centrally managing intake and development. For example, context-based prioritization of event, incident, threat, risk, vulnerability and any other remediation activity should be standardized, built once and used many times.
• Catch and block, review and release: Implement a model where AI automates tedious, error-prone, high-volume “catch and block” tasks and curates events for cybersecurity professionals' “review and release” decisions that require judgment and authorization.

With organizations implementing AI across the business, the cybersecurity function has a near-term opportunity to become a trusted partner to help others realize the value creation potential from AI-based solutions.

Rapid adoption of AI can leave an organization vulnerable to new cyber-attacks and compliance risks. Cyber teams need to take on a more strategic, proactive and integrated role within the enterprise to install appropriate controls as AI functions and experiments proliferate.

Tackling the cyber threat in AI expansion

Adversaries are already targeting vulnerabilities in AI systems. Security researchers have used prompt injection – engineering prompts to deceive systems into bypassing filters or guardrails – to attack conversational bots from the likes of Bard and OpenAI.⁴ White hat researchers have demonstrated how data poisoning – feeding malicious data into algorithms to manipulate its output – can be launched on popular data sets at low cost with minimal technical skills.⁵ In another project, stickers were added to a stop sign to trick an autonomous vehicle into misreading it as a “45 miles per hour” sign.⁶ Researchers elsewhere crafted inaudible sounds capable of injecting malicious voice commands to AI-powered voice assistants.⁷

In addition to attacks from bad actors, organizations need to ensure employees do not breach compliance or regulations while using AI, such as by exposing sensitive data, intellectual property or restricted material into an AI model to run queries or perform tasks. “There are so many tools out there, and they work in different ways and with different risks. It’s very easy for someone to sign up and start using them,” says a manufacturing organization’s CISO.

The 2023 study shows that only 36% of CISOs are satisfied with the non-IT workforce’s adoption of cyber best practices. The need for AI cyber training and education is further evidenced in recent academic research trends from our topic clustering analysis. Nearly 50% of literature around organizations’ cyber management involves training and education, comprising the largest topic in this space. Additionally, 23% of that research includes the intersection of AI with training and education — an area that workers are looking for more guidance. According to upcoming EY research, only 62% of US workers say their employer has made educating employees about responsible AI usage a priority.

Cartwright at Asahi also argues that AI tools for generating outputs like customer insights need to be properly managed in terms of consent and data re-use protocols. “You've got to make sure that the development environments, and particularly the data science development environments, have strong controls and are well-protected,” he says. The interviewees also noted the importance of instituting explainability, such as ensuring a credit limit decision does not fall foul of anti-discrimination regulations regarding the data it draws from, faulty inferences or misleading proxy data.

Opportunities for cybersecurity to improve AI implementation in different domains:

Visibility from the top

Effective CISOs are able to communicate the value of a strong cybersecurity posture up, across and out into the organization. Awareness of AI risks among the C-suite and board provides an opportunity to build upon. As exemplified in the 2023 study, CISOs have already started to expand their influence, with more interaction with the board and more CISOs reporting directly to the C-suite. Building confidence with the board and C-suite is rooted in transparency.

“One thing that that is becoming really important is the ability to engage with businesses transparently so that they feel comfortable picking up a phone and just having a conversation. The days of security being something in the backroom are gone,” says Cartwright at Asahi. He believes transparent conversations with the board and accountability in cyber decisions paves the way for CISOs to become more strategic across the organization.

Members of the C-suite often overestimate the effectiveness of their organization’s overall approach to cybersecurity (48% satisfied versus 36% of CISOs) with gaps smaller for Secure Creators, suggesting more transparency with senior leaders and a shared understanding of risk is important as AI implementation progresses.

In parallel, organizations need to begin to explore capabilities to detect “shadow AI.” Similar to the early days of cloud, organizations have already fallen victim to well-intended experimentation with AI in non-production environments leading to sensitive data exposure, model theft and excessive, unexpected solution costs due to ungoverned implementations. These sorts of setbacks put both the business value and the risk posture of organizations in question.

A 360 view on enterprise-wide AI

An outward-facing CISO can help an organization improve overall AI adoption by using cybersecurity as a framework for coordination. Some companies are forming AI advisory bodies to provide coordination of AI initiatives which can both tackle the shadow AI problem and improve visibility on AI experimentation. One asset manager has set up such an entity — staffed with representatives across business groups, including cyber — for anyone in the organization seeking to utilize AI, providing rules around shareable data and restrictions on sending data outside of the organization.

Cybersecurity is becoming a core component in operational decisions on the ground too. A CISO from a Europe-based retail manufacturer exemplified this integration, noting, “Procurement is now aware that when they are starting a new project, they will contact us, then we can give them our requirements for upcoming suppliers and upcoming applications they want to use.”

Strong cybersecurity across AI gives teams confidence to experiment securely, helping companies identify practical applications and clearly define the return on investment. One CISO we spoke to says their cyber team helped stand up their own instance of ChatGPT so that other business functions could work within the confines of the organization’s four virtual walls.

Finding a common language in cyber

Breaking down barriers to cybersecurity starts with a familiarity with the topic at large. Asahi credits holding regular cyber-related “lunch and learn” sessions to kickstart the business to think more about cybersecurity. Cartwright noted that these don’t necessarily have to be about the biggest cyber threats like phishing, but the goal is focused on making the topic of cybersecurity accessible for all.

Bupa is another example, where the CISO is trying to bridge the gap with the business by ensuring cyber metrics are included in reporting metrics. "In every business performance committee, we are working to embed cybersecurity metrics, trying to embed metrics in terms of cyber performance. It’s not perfect, it’s a journey, but we are trying to make cyber part of business metrics," says group CISO at Bupa.

Actions for CISOs:

• Embed cyber professionals into the AI use case identification and intake and governance process: this early-stage insertion will allow for cyber integration commensurate with the sensitivity of the data and business function.
• Publish and govern AI acceptable use standards across the business: outline the guardrails and guidance under which the business and supporting technologists should design and build AI solutions. Adopt a set of technical cyber controls that align to emerging AI industry standards frameworks like the US National Institute of Standards and Technology’s AI Risk Management Framework and the EU AI Act.
• Implement AI-specific risk mitigation: consider the unique characteristics and challenges associated with AI systems, such as complexity, adversarial attacks, lack of interpretability, continuous learning and ethical considerations.

Secure Creators work with the C-suite to help build strategies that drive innovation and value creation across the enterprise. The emergence of AI is another opportunity for cybersecurity functions to demonstrate their value to the organization. With AI applications freeing up time for the cyber team to focus on value-add objectives, cyber professionals can help the rest of the business drive value from AI with confidence. 

CISOs have a near-term opportunity to become a trusted partner, helping teams maximize the value creation potential from the AI tools they look to implement. Helping the business confidently deploy AI can shift the perception of cybersecurity from a team that slows things down to one that enables confident technology adoption at an accelerated pace. By setting up processes that incorporate cyber early, other functions will gain efficiencies by minimizing budget issues or delays.

Integrating cyber into AI initiatives is an opportunity for cyber functions to expand their influence across the organization. Leading cyber teams are showing their input can inform better decisions on everything from acquisitions to supply chain governance. One CISO is deeply involved in the holistic evaluation of acquisition targets, something increasingly important given CEOs’ increased appetite for M&A in 2024.⁸ The same CISO builds confidence with shareholders by providing information and assurance regarding the firm’s ability to protect their information. Similarly, ANZ’s Ananthapavan and his team provide strategic threat intelligence that feeds into business decision-making.

One CISO emphasizes how cybersecurity can drive sales and increase the bottom line by creating confidence with customers. "You have a number of customers who are putting more and more focus on certifications, questionnaires, ascertaining that their suppliers are meeting a certain level of diligence and us demonstrating that we do so either helps to keep existing customers happy or open new markets for us, in which case, we should be able to quantify that for the business.”

AI also enables the cyber function to make decisions and conduct analyses quicker, streamline processes for cost savings, and reduce the need for additional employees. This can be essential for complying with regulatory demands but also to quickly respond to market opportunities.

Actions for CISOs:

• Establish AI principles and guardrails to support experimentation: As businesses rapidly experiment and adopt AI it is essential for CISOs to move quickly to protect and accelerate the rate of innovation.
• Help the business get use cases to market faster: Develop a pre-configured and pre-sanctioned set of architectures, integration patterns and technology stack components to support business use cases. Make secure by design the fastest route to market in your organization.
• Target cyber enablement: Leveraging a practical AI security and risk framework to aid in getting to “yes” for the business while remaining within risk tolerances reversing the perception that cybersecurity is the business prevention department.
• Gain visibility of the AI attack surface and third-party ecosystem: Many CISOs have spent a lot of time in front of their Boards and executive teams responding to third-party data breaches. Our research showed that Secure Creators have strategies in place to manage all cyber risks across the attack surface and their third-party ecosystem. Expanding this to cover new AI attack surfaces will allow organizations to adopt AI with confidence.

While leading organizations are enthusiastic in onboarding AI for cybersecurity, they are still at the early stages in bringing cybersecurity across the business as it implements AI. The most successful CISOs will be those who can articulate the value of cybersecurity to the enterprise in the AI era, beyond narrow definitions of security, giving the business confidence that they can adopt AI securely.
