Identity-aware proxy (IAP) is more than just a way to control access. It’s a critical tool for limiting third-party risks, especially as organizations continue to adopt cloud apps and distributed systems. While third-party integrations improve speed and scalability, they also expand the attack surface. That’s where a proactive and security-focused approach like Identity-Aware Proxy comes in to ensure users and tools gain access only when they meet strict policies.
This blog post will break down how Identity-Aware Proxy works, why it’s important for managing third-party risks, and actionable ways to implement it effectively.
What is Identity-Aware Proxy?
An Identity-Aware Proxy (IAP) sits between users and your applications or resources, creating a security layer that evaluates the identity, context, and other factors before granting access. Unlike traditional, network-based controls, identity-aware proxies focus on who is accessing the system rather than where they are accessing from.
By using identity-based rules, IAP enables more granular and effective control, especially important when third-party tools and services are involved. This ensures limited access aligned with the principle of least privilege, reducing the potential attack surface.
Why Third-Party Risk Assessment Matters
Third-party services are often the weakest link in your security posture, regardless of how secure your own systems are. By their very nature, integrations with third-party tools mean extending trust to external systems. However, these systems might not adhere to your security standards, making them potential entry points for unauthorized access.
Risks include:
- Over-access permissions: Granting too much access to third-party identities could result in breaches if credentials are compromised.
- Misconfigured third-party tools: A misconfiguration in an external integration can expose sensitive data to unauthorized actors.
- Insider threats: External vendors often have temporary or contractual employees with access to your systems, increasing risks of misuse.
- Compliance gaps: Regulations like GDPR, HIPAA, and others demand strict control over shared data. A lack of well-defined access policies for external vendors can lead to noncompliance penalties.
An Identity-Aware Proxy strengthens the governance over these risks by enforcing strict identity validation checkpoints at access time.
How IAP Mitigates Third-Party Risks
When Identity-Aware Proxy is integrated into your tech stack, it provides several distinct advantages for third-party risk assessment and mitigation:
