39
00:01:41,700 --> 00:01:44,280
functions: identify, protect, detect,

40
00:01:44,280 --> 00:01:47,280
respond, and recover. Each function is

41
00:01:47,280 --> 00:01:49,380
further broken down into categories and

42
00:01:49,380 --> 00:01:51,360
subcategories that provide more specific

43
00:01:51,360 --> 00:01:53,280
guidance on how to implement the

44
00:01:53,280 --> 00:01:54,540
