1 00:00:03,040 --> 00:00:03,640 Okay. 2 00:00:03,670 --> 00:00:07,450 Let's summarize what we've learned about Adnan templates in this module. 3 00:00:08,380 --> 00:00:14,260 So group policies, main job is lockdown and this is implemented primarily in admin template policy. 4 00:00:15,160 --> 00:00:19,780 Security policy certainly has a role here and I'll talk about that in the next module. 5 00:00:19,810 --> 00:00:25,390 But group policies, history comes from admin templates and the capabilities of being able to push registry 6 00:00:25,390 --> 00:00:27,850 values into a given computer or user. 7 00:00:28,750 --> 00:00:32,110 So admin templates generally does not tattoo a system. 8 00:00:32,230 --> 00:00:36,880 This is a development that Microsoft made great strides on when they introduced group policy. 9 00:00:37,750 --> 00:00:43,600 When you apply a group and admin template setting to a system or a user, it gets applied in push there. 10 00:00:44,450 --> 00:00:50,000 And if you remove that GPO, the next processing cycle that happens will remove that old setting from 11 00:00:50,000 --> 00:00:54,890 the system and reapply the new settings so that tattooing doesn't happen. 12 00:00:54,890 --> 00:00:56,090 And that's a great thing. 13 00:00:56,960 --> 00:01:00,380 You can extend what can be controlled using admin templates. 14 00:01:01,310 --> 00:01:07,280 So these underlying IDM, x and ADMA files that are the things that generate what you see in editor, 15 00:01:07,280 --> 00:01:08,450 those can be extended. 16 00:01:09,350 --> 00:01:15,500 You can write your own custom DMX and ADMA files and I gave you a link to a free Microsoft tool called 17 00:01:15,500 --> 00:01:19,490 Adam X Migrate that has an authoring tool in it that lets you do these things. 18 00:01:20,420 --> 00:01:26,120 They are very powerful in that you can really customize any registry entry or any registry edit that 19 00:01:26,120 --> 00:01:29,000 you want using an add amex or ADMA file. 20 00:01:29,850 --> 00:01:34,830 And of course, if it's not in one of those four special policy keys I talked about, it will probably 21 00:01:34,830 --> 00:01:35,820 tattoo the system. 22 00:01:35,910 --> 00:01:41,880 But nonetheless, you have the flexibility to really write a custom dmcs for really any registry value 23 00:01:41,910 --> 00:01:42,690 you want to set. 24 00:01:43,590 --> 00:01:46,530 You can deploy admin templates settings in layers. 25 00:01:47,460 --> 00:01:52,470 So what I had suggested it is that you can provide kind of base level lock down for general things like 26 00:01:52,470 --> 00:01:55,080 Explorer and the Start menu and the desktop. 27 00:01:55,960 --> 00:02:00,850 And then if you have other more specific application, specific lockdowns you want to do, like in your 28 00:02:00,850 --> 00:02:06,370 office, you can create separate GPOs that contain all the settings for IEEE or all the settings for 29 00:02:06,370 --> 00:02:08,350 office for a particular business unit. 30 00:02:09,210 --> 00:02:14,280 And this is a good way of kind of approaching the problem from a layering perspective, not duplicating, 31 00:02:14,280 --> 00:02:20,520 but providing kind of an additive use of admin templates and taking advantage of the hierarchical processing 32 00:02:20,520 --> 00:02:22,230 model that group policy has. 33 00:02:23,100 --> 00:02:28,830 And then finally, in terms of discoverability, you know, there are literally thousands of admin templates 34 00:02:28,830 --> 00:02:29,810 settings out there. 35 00:02:29,850 --> 00:02:31,020 So how do you find them? 36 00:02:31,860 --> 00:02:35,250 Well, there's the Microsoft setting spreadsheet that I talked about. 37 00:02:35,340 --> 00:02:39,180 You can get from the Microsoft download site or the search app. 38 00:02:39,300 --> 00:02:44,510 It's an online Web app found on the Microsoft Azure site developed by somebody at Microsoft. 39 00:02:44,520 --> 00:02:47,760 And it gives you the ability to interactively search on keywords. 40 00:02:48,630 --> 00:02:53,930 And essentially what it does is discover within the current admin templates that Microsoft provides, 41 00:02:53,940 --> 00:02:57,240 and it is specific to the Microsoft admin template settings. 42 00:02:58,160 --> 00:03:03,230 It can give you the ability to search on settings to find a particular area that you're interested in 43 00:03:03,230 --> 00:03:04,040 locking down. 44 00:03:04,910 --> 00:03:06,590 So that's a great resource. 45 00:03:06,590 --> 00:03:11,720 And what we're going to do next is talk about how security policy lends itself to this whole notion 46 00:03:11,720 --> 00:03:12,470 of lockdown.
