In today’s digital landscape, non-human identities (NHIs) have become an integral part of modern enterprise operations. From APIs and bots to service accounts and IoT devices, these digital entities are revolutionizing how businesses function. However, with this technological advancement comes a new set of cybersecurity risks that organizations must address.
The Staggering Scale of Non-Human Identities
Recent research reveals a startling statistic: non-human identities now outnumber human users by a ratio of 45 to 1 in many IT ecosystems. This exponential growth has created a vast and often overlooked attack surface for cybercriminals to exploit.
Top Threats to Non-Human Identities
The OWASP Top 10 Non-Human Identities Risks for 2025 provides a comprehensive overview of the most critical security risks associated with NHIs. Let’s examine some of these threats and compare them with other industry findings:
1. Improper Offboarding
OWASP highlights the risk of inadequately deactivating or removing NHIs when they’re no longer needed. This aligns with industry observations about the challenges of managing the lifecycle of non-human identities. Many organizations struggle with tracking and decommissioning unused service accounts, leaving potential backdoors for attackers.
2. Secret Leakage
The exposure of sensitive credentials like API keys and tokens is a significant concern. This risk is echoed in other sources, which emphasize the dangers of storing secrets in plaintext or hardcoding them into source code. Such practices can lead to unauthorized access and data breaches.
3. Overprivileged NHIs
OWASP warns against assigning excessive privileges to NHIs. This issue is widely recognized in the industry, with experts stressing the importance of implementing the principle of least privilege. Overprivileged identities, if compromised, can give attackers broad access to critical systems.
Mitigation Strategies for Businesses
To address these threats, organizations should consider the following steps:
- Implement Robust Lifecycle Management: Automate the provisioning, rotation, and de-provisioning of NHI credentials. This helps ensure that unused or outdated identities are promptly removed, reducing the attack surface.
- Enforce the Principle of Least Privilege: Grant NHIs only the minimum permissions necessary for their specific functions. Regularly review and adjust access rights to maintain a strong security posture.
- Continuous Monitoring and Auditing: Implement systems for real-time monitoring of NHI activities. This allows for quick detection of anomalies and potential security breaches.
- Secure Secrets Management: Utilize dedicated secrets management solutions to store and protect sensitive credentials. Avoid hardcoding secrets in source code or storing them in plain text.
- Regular Security Assessments: Conduct periodic audits of your NHI landscape to identify and address potential vulnerabilities.
The Human Element in Managing Digital Identities
While technological solutions are crucial, it’s important to remember the human aspect of managing NHIs. As Mitch Greenfield from Humana points out, “The complexity grows as you manage thousands of applications and more than 100,000 entities. Without proper integration and governance, the risks multiply”.
This highlights the need for a cultural shift within organizations. Businesses must treat non-human identities with the same level of attention and security as human ones. It’s not just about implementing tools; it’s about fostering a security-conscious mindset across all levels of the organization.
Conclusion: A Call to Action
As we navigate the evolving landscape of digital identities, the management of NHIs has become a critical component of cybersecurity strategy. The risks are real and growing, but so are the solutions available to mitigate them.
By taking proactive steps to secure non-human identities, businesses can turn what could be a vulnerability into a strength. As Parham Eftekhari of CyberRisk Alliance reminds us, “Every unmanaged or under-secured identity is a potential breach waiting to happen”. The time to act is now – before these silent threats become tomorrow’s headlines.
