Detecting “Effluence”, An Unauthenticated Confluence Web ShellWhile companies are increasingly investing in the security of their technology, systems and data, cyber risks continue to proliferate. Cyber-security vulnerabilities can threaten business continuity and cost organizations millions of dollars per incident: the global average cost of a data breach was $4.35 million in 2022. In addition to external dangers such as ransomware and phishing attacks, insider cyber threats are raising the threat level for businesses across sectors. Research shows that while leaders understand the importance of cyber security, many CEOs struggle to make decisions in this area.
What can leaders do to not only build their organizations’ cyber security but also strengthen their cyber resilience? Aon’s 2023 Cyber Resilience Report collected data from more than 2,000 clients to explore how businesses around the world are managing a rise in cyber risks, where organizations are making gains and which actions could help them prepare to face future cyber security challenges.
Aon’s Cyber Resilience Report found that businesses overall have increased their cyber-security budgets from 2020 levels, with improvements in data security, application security, remote work, access control and endpoint and systems security. The insurance market could be a driver in the move toward greater cyber health, because cautions from insurers have motivated businesses to implement more stringent cyber security controls. Though certain threats — such as vulnerability to inside attacks, reputation risk relating to a cyber incident and insufficient backup security for critical company data — persist, some industries appear to be making notable progress in improving their stance on cyber.
The finance and insurance sector show gains in cyber readiness in 2022, with small and midsize companies moving beyond a basic level of cyber maturity. Clients in this industry also indicated that they have increased their cyber security spend from 2021 levels, with 8 percent of their IT budgets devoted to this area last year. The use of multifactor authentication (MFA), a valuable security protection for financial data, also appears to have increased in 2022; in the U.S., deployment of MFA controls rose to 80 percent from 65 percent in 2021.
However, the finance and insurance sectors still face challenges in cyber resilience. With more customers turning to mobile banking and new forms of digital payment, the growing fintech sector is vulnerable to data breaches, malware and ransomware. And ransomware isn’t only a threat to fintech providers: the finance and insurance industry as a whole reported a 38 percent increase in ransomware claims from fourth quarter 2022 to first quarter 2023.
Preparing for ransomware attacks is just one of the actions the finance and insurance sector can take to build cyber resilience. Optimizing cyber insurance, mapping and managing third-party risks, and running a patch management program are also important steps in the journey to stronger cyber security. Finance and insurance businesses in Europe will also need to prioritize meeting the standards of the Digital Operation Resilience Act (DORA) in the next two years.
The healthcare industry faces unique cyber-security challenges, complicating the industry’s path to cyber maturity. The need to protect sensitive patient data, an industry-wide IT talent gap, potential liabilities related to regulatory compliance and a move to new technology rooted in the Internet of Things (IoT) are all critical considerations for healthcare companies. In this industry, cyber attacks are not only disruptive and costly — they can also lead to harmful or life-threatening outcomes for patients.
Like the finance and insurance sector, the healthcare industry devoted 8 percent of IT budgets to security in 2022. But the threat of ransomware looms large in healthcare as well: Aon’s Cyber Resilience Report found that while U.S. healthcare companies made notable improvements in protective strategies such as multifactor authentication, U.K. and EMEA healthcare companies lacked 41 percent of critical MFA controls.
To mitigate the risk of ransomware and other cyber threats, the healthcare industry can develop a better understanding of its cyber-security exposures. Building cyber resilience through collaboration with internal enterprise operations emergency centers can also strengthen cyber maturity across a healthcare organization. Improving the relationship between business continuity planning and incident response preparedness can contribute to greater alignment in cyber strategy as well. In Europe, the healthcare industry will also need to follow the new Network and Information Security (NIS2) Directive or face potential fines for noncompliance.
Manufacturing relies on networks of partners of varying sizes and capabilities, and the interconnectedness of the industry expands the footprint for cyber risk. A severe cyber incident has the potential to disrupt the supply chain, and the many smaller companies in the manufacturing ecosystem may have fewer resources to combat a cyber attack. Vulnerabilities in industrial IoT and the lingering effects of COVID-19-era pressures add to the challenges in building cyber resilience in manufacturing.
The industry is making strides in cyber maturity, however. Outpacing finance and insurance and healthcare, manufacturing companies allocated 8.5 percent of their IT budgets to cyber security in 2022. Though manufacturing still has room to grow in terms of cyber health, U.S. and U.K. manufacturers surpass other sectors in operational technology.
As in other industries, cyber resilience in manufacturing begins with understanding and managing risk. Focusing on response and recovery strategies and segmenting systems — including a separation of IT and operational technology to minimize in-network threats — could help to build a stronger cyber risk profile. Manufacturers in Europe must also turn their attention to regulatory compliance, upholding the standards outlined by the European Union Agency for Cybersecurity; U.S. manufacturers will need to comply with guidelines set by the National Institute of Standards and Technology.
To build cyber resilience, business leaders can consider a holistic approach. IT, finance, HR, risk and other departments are all susceptible to cyber attacks, and all departments can benefit from improvements in cyber strategy. The Aon Cyber Resilience Report identifies steps businesses in any industry can take as they progress toward greater cyber maturity:
