19.13. Security Domains

This section is intended to equip you with a basic understanding of the term security domain and its casual equivalent security sandbox, which is commonly used in Adobe's documentation and other third-party resources. For reasons described in the next section this book avoids the use of both terms.

Taken in combination, a given .swf file and the logical set of resources which that .swf file can freely access via accessing-content-as-data, loading-data, and cross-scripting operations (per Table 19-3 through Table 19-6) conceptually form a group known as a security domain. From the perspective of a .swf file from each of the four security-sandbox-types, Table 19-9 lists the constituents of that .swf file's security domain.
