NIST has published Special Publication (SP) 1800-5, “IT Asset Management” to help financial service companies monitor and manage IT assets.  According to the release:

“The example solution…gives companies the ability to track, manage, and report on information assets throughout their entire life cycle. This can ultimately increase cybersecurity resilience by enhancing the visibility of assets, identifying vulnerable assets, enabling faster response to security alerts, revealing which applications are actually being used, and reducing help desk response times.”
