External Resource Integrity

V3.6.1

Verify that client-side assets, such as JavaScript libraries, CSS, or web fonts, are only hosted externally (e.g., on a Content Delivery Network) if the resource is static and versioned and Subresource Integrity (SRI) is used to validate the integrity of the asset. If this is not possible, there should be a documented security decision to justify this for each resource.

Required for Level 3

CAPEC™ (3.9): 104, 152, 160, 184, 19, 207, 233, 242, 267, 444, 446, 475, 63
