User identity is only half the story. Learn how device posture shapes secure access decisions and how SGNL makes it actionable in real time.
Identity security has emerged as a critical focus area in cybersecurity. As organizations adopt zero-trust architectures and shift to cloud-based environments, the traditional perimeter-based security models are no longer sufficient. One crucial aspect gaining prominence in this context is device posture: the security status of the devices accessing organizational resources. Understanding and managing device posture is essential for robust identity security. So let’s talk about how to make that happen.
Device posture refers to the current security state of a device, encompassing factors such as operating system version, patch levels, presence of security software, encryption status, and compliance with organizational policies. In a zero-trust model, every access request is evaluated based on multiple parameters, including user identity, device posture, location, and the sensitivity of the requested resource. A device with a compromised or non-compliant posture can pose significant risks, even if the user credentials are valid.
Incorporating device posture into identity security strategies enhances the ability to enforce stricter policies in order to reduce risk. By continuously assessing the security status of devices, organizations can enforce policies that restrict access from devices that do not meet predefined security criteria. This approach mitigates risks associated with compromised devices and ensures that access is granted only when both the user and the device are deemed trustworthy. This approach also enables you to leverage your existing investment in device posture assurance (through device management and XDR) to secure access to the cloud.
SGNL, the leader in identity-first security solutions, emphasizes the importance of device posture in its security framework. By integrating with various device management and endpoint detection systems, SGNL enables organizations to incorporate device posture assessments into their access control policies. This integration allows for real-time evaluation of device compliance and facilitates dynamic access decisions based on the current security status of the device.
For instance, SGNL’s platform can asynchronously receive signals from device management systems indicating changes in device posture. If a device falls out of compliance due to outdated software, missing security patches, or detection of malicious activity, SGNL can automatically enforce policies that restrict or revoke access for that device. This proactive approach ensures that only secure and compliant devices can access sensitive resources, thereby strengthening the organization’s overall security posture. You can see an example of this in action in this video:
The Continuous Access Evaluation Profile (CAEP) defines a “Device Compliance Change” event, which is useful in conveying update device posture information to independent services that can use it to make access decisions. A key component of SGNL’s strategy is the implementation of the Action Framework - either using the CAEP or the more general Shared Signals Framework (SSF) standards, or through proprietary integrations where the standards are not yet supported. The Action Framework allows for ongoing assessment of access permissions based on real-time context, including device posture. By leveraging CAEP, SGNL facilitates the exchange of security signals between systems. SGNL has proven interoperability with providers such as Jamf and Omnissa who support the CAEP device compliance change event. SGNL can consume these events to enforce policies. This enables immediate responses to changes in device posture, such as revoking access or prompting re-authentication, thereby minimizing the window of opportunity for potential threats.
Incorporating device posture into identity security frameworks offers several advantages:
To effectively integrate device posture into identity security strategies, organizations should consider the following steps. Most enterprises will have the first three steps below already in place, but I’m including them here for completeness:
As cyber threats continue to evolve, organizations must adopt comprehensive security strategies that encompass both user identity and device posture. By integrating device posture assessments into identity security frameworks, organizations can enhance their ability to detect and respond to potential threats, enforce compliance, and maintain a robust security posture. Solutions like SGNL provide the tools necessary to implement these strategies effectively, enabling organizations to navigate the complexities of modern cybersecurity with confidence.
