The Rise of Machine Identities: A Growing Challenge for Organizations
Today, organizations are facing an evolving and often underestimated security challenge: the proliferation of machines, including non-human identities (NHIs) also known as machine identities. As artificial intelligence, workloads, and devices continue to transform business operations, the number of machine identities, including AI Models, AI Agents, bots, applications, code, APIs, devices, and IoT devices, is expanding at an unprecedented rate. While these identities are essential for efficiency and scalability, they also pose significant risks if not properly managed.
Unlike traditional user identities, Machine Identities are created for software applications, automated processes, and interconnected devices, such as smart home assistants and industrial IoT sensors, to enable seamless communication, automation, and efficiency. As cloud adoption, AI, IoT, and DevOps accelerate, organizations now manage vast numbers of machine identities, which rely on APIs, service accounts, and automation tools for secure operations and AI-driven decision-making.
While machine identities offer numerous advantages, they also introduce a range of cybersecurity and governance risks. One major concern is credential mismanagement and privilege creep. Machine identities may sometimes require elevated privileges to function effectively, but organizations frequently overlook proper governance and access controls design, leading to over-permissioned accounts that become vulnerable targets for attackers. Without proper access control mechanisms in place, machine identities can be exploited to gain unauthorized access to critical systems, including crown jewel assets.
Another significant risk is the lack of visibility and accountability. Unlike human users, machine identities in many organizations are not tied to a single responsible party. Often organizations lack insight into how these identities are being used, who is managing them, and what access they have. For example, a scarcely used API leveraging a hardcoded secret with excessive privileges or an orphaned service account still able to access a critical server or application. This obscurity makes it difficult to detect machine identity abuse and enforce appropriate security controls and policies.
Additionally, given the increasing attack surface granted by unmanaged machine identities, cybercriminals are increasingly targeting these accounts with the hope of leveraging a vulnerable yet privileged secret. A compromised secret, service account, or bot credential can provide adversaries with an entry point into critical infrastructure, potentially leading to data breaches, ransomware attacks, and/or supply chain compromises.
Ineffective identity lifecycle management is another issue. Machine identities are often created dynamically and remain active indefinitely, even after their intended function has ended. Organizations frequently fail to decommission unused machine identities, leading to a build-up of obsolete but still valid credentials that attackers can exploit. Regulatory and compliance challenges add another layer of complexity since certain regulatory standards require stringent access controls particularly for accounts with access to core financial systems and processes.
Mitigating the risks of machine identities involves changes across people, processes, and technology. Organizations must first focus on discovering all machine identities within their ecosystem and evaluating the risks associated with each. From there, they must design and implement security controls enabled by specific technology that can effectively manage and protect these types of identities. Finally, training employees on strict processes and advanced technology for managing the entire lifecycle of NHIs is also crucial to ensuring compliance and reducing vulnerabilities.
A structured approach is key to securing machine identities effectively. For example, CyberArk, a leader in identity security, provides solutions that help enable organizations to effectively manage and rotate machine identities, identity secrets, and automate their lifecycle management. Their platform enables IT teams with robust and dynamic secrets and certificates management, the ability to apply access controls, and continuous monitoring to reduce security vulnerabilities and strengthen compliance. By leveraging such technologies, businesses can increase automation of manually managing these operations while reducing the risks associated with machine identities.
As organizations continue to embrace digital transformation, the number of non-human identities will only grow. A well-structured and security-conscious approach to NHI management is essential for safeguarding critical assets and maintaining regulatory compliance. By acknowledging and addressing the risks associated with NHIs, organizations can strengthen their security posture while increasing the benefits of automation and paving the way for agentic AI-driven process automations. In addition to securing software embedded transactions and the ability to secure NHIs on IoT devices. In an era where machines are becoming as integral to business operations as humans, ensuring the security of non-human identities is no longer optional—it is imperative.
