How can we leverage ServiceNow in a Zero Trust environment?

Background

Zero Trust is a cybersecurity strategy wherein security policy is applied based on context established through least-privileged access controls and strict user authentication. Rooted in the principle of “never trust, always verify, " devices should not be trusted by default, even if they are connected to a trusted network such as a corporate LAN, and even if they were previously verified.

Leveraging the CISA Zero Trust Maturity Model, ServiceNow has multiple products to drive the adoption of Zero Trust and its pillars.

By mapping the pillars to the ServiceNow features, customers can quickly roll out Zero Trust with a strategic approach to enhance their Zero Trust posture.

Recommendation

Familiarize yourself with the CISA Zero Trust Maturity Model to better understand the mapping checklist. ServiceNow can deliver on a Zero Trust using SIR, which covers Network / Environment, application Workload, and Device under the Maturity Model. Steps to enabling the capabilities are to allow SIEM to data ingestion, automation via workflow, and create response playbooks.
