1 00:00:03,050 --> 00:00:03,650 Okay. 2 00:00:03,680 --> 00:00:08,030 Now I want to talk about some deployment scenarios using security policy. 3 00:00:08,890 --> 00:00:14,260 And the first one I'm going to go through is group membership control, which is a pretty common scenario 4 00:00:14,260 --> 00:00:20,290 in a lot of situations, whether you're talking about controlling membership on desktops or servers, 5 00:00:20,470 --> 00:00:23,350 there are two ways to enforce the local group membership. 6 00:00:24,210 --> 00:00:29,280 And again, I'm going to reiterate that group policy does local group membership control. 7 00:00:30,140 --> 00:00:35,270 It does not do anything with respect to groups that are defined in Active Directory and that's a key 8 00:00:35,270 --> 00:00:35,960 distinction. 9 00:00:36,830 --> 00:00:42,230 You'll need other mechanisms besides group policy to control membership on Active Directory groups. 10 00:00:43,100 --> 00:00:47,090 But let's look at the ways that we can do this in group policy for local groups. 11 00:00:48,020 --> 00:00:51,020 So the first way is restricted groups policy. 12 00:00:51,920 --> 00:00:56,660 So you have the ability through restricted groups to do a couple of different kinds of control, which 13 00:00:56,660 --> 00:00:57,920 I'll talk about in a second. 14 00:00:57,920 --> 00:01:02,450 And that gives you the ability to essentially pretty much lock down the membership of the group and 15 00:01:02,450 --> 00:01:04,380 also which groups are in other groups. 16 00:01:04,400 --> 00:01:10,400 So adding groups to groups or adding users to groups the other way is actually through preferences, 17 00:01:10,580 --> 00:01:12,310 through group policy preferences. 18 00:01:12,320 --> 00:01:17,060 And I mentioned or alluded to this that even though group policy preferences has this preferences name 19 00:01:17,060 --> 00:01:22,070 in it, it is capable of doing lock down if the thing that you're controlling is generally not accessible 20 00:01:22,070 --> 00:01:23,150 to the normal user. 21 00:01:24,050 --> 00:01:26,330 So for example, group membership. 22 00:01:27,190 --> 00:01:32,260 If the user is not a local administrator on their workstation, they cannot adjust group membership 23 00:01:32,380 --> 00:01:36,940 no matter how it's delivered to them, whether it's through restrictive groups or through this control 24 00:01:36,940 --> 00:01:39,670 panel settings, local users and groups policy. 25 00:01:40,600 --> 00:01:43,960 So these two mechanisms provide similar features. 26 00:01:44,880 --> 00:01:47,660 I'll talk about where they're different, what the differences are. 27 00:01:47,670 --> 00:01:52,170 And in terms of, you know, controlling group membership on workstations and servers. 28 00:01:53,070 --> 00:01:58,680 So restricted groups allows you to create list of users or domain groups that you wish to be added as 29 00:01:58,680 --> 00:02:00,120 a member of a local group. 30 00:02:01,030 --> 00:02:02,920 So here's a scenario for this. 31 00:02:03,820 --> 00:02:09,100 The Workstation, Windows Workstation and Number Servers have a local group that's built in called remote 32 00:02:09,100 --> 00:02:10,120 desktop users. 33 00:02:10,240 --> 00:02:13,960 And members of this group can remote desktop to a server workstation. 34 00:02:14,830 --> 00:02:20,290 Now you might decide that you want your help desk users in Active Directory to be able to remote desktop 35 00:02:20,290 --> 00:02:22,450 to any desktop in your organization. 36 00:02:23,320 --> 00:02:29,110 So you can imagine creating a restricted groups policy that adds the Help Desk Group if there is such 37 00:02:29,110 --> 00:02:32,560 a thing in your domain to the local remote desktop users group. 38 00:02:33,430 --> 00:02:37,510 And that is perfectly, perfectly something you can do with restricted groups. 39 00:02:38,470 --> 00:02:43,540 The other thing you can do with restricted groups is have absolute control over the membership of a 40 00:02:43,540 --> 00:02:44,230 given group. 41 00:02:45,100 --> 00:02:50,440 And in that scenario, it will actually dynamically remove users in groups that are not in your so-called 42 00:02:50,440 --> 00:02:53,230 approved list east each time processes. 43 00:02:54,160 --> 00:03:00,280 So this is kind of cool and actually somewhat dangerous in that you can really shoot yourself in the 44 00:03:00,280 --> 00:03:03,160 foot if you don't build your group memberships correctly. 45 00:03:04,060 --> 00:03:09,400 But the point here is that the this particular mode of restricted groups has the ability to very tightly 46 00:03:09,400 --> 00:03:10,690 define group membership. 47 00:03:11,560 --> 00:03:14,200 Now the members of this group side of restricted groups. 48 00:03:14,350 --> 00:03:17,230 There's two boxes that you saw in that previous screen. 49 00:03:17,260 --> 00:03:21,850 The members of this group side are about absolute control that I was just talking about. 50 00:03:22,730 --> 00:03:27,350 The group is a member of side is where you would add users and groups to other groups. 51 00:03:28,280 --> 00:03:32,750 So you have to be careful when you're defining this and I'm going to go through this in a demo. 52 00:03:32,930 --> 00:03:34,790 Which side you're defining membership on? 53 00:03:35,060 --> 00:03:40,040 Because one side is absolute control and the other side is sort of discretionary control. 54 00:03:40,940 --> 00:03:45,380 Now with GP preferences, local users and groups, it's a little bit different. 55 00:03:46,310 --> 00:03:51,290 So with this you have a way to essentially add users and groups to another group, and that's really 56 00:03:51,290 --> 00:03:53,730 the main capability that this feature provides. 57 00:03:54,650 --> 00:03:58,410 But it also lets you rename the local group or add a description to it. 58 00:03:58,430 --> 00:04:02,060 You can delete all member users or all member groups from a group. 59 00:04:02,960 --> 00:04:07,940 So this is kind of almost similar to the absolute control power, except that it's just going in through 60 00:04:07,940 --> 00:04:11,840 and sweeping through all member users and all member groups to clear out the group. 61 00:04:12,700 --> 00:04:16,360 And then you can add or remove specific members to or from a group. 62 00:04:17,230 --> 00:04:22,690 So I can say, for example, that my helpdesk admins group will be added to the Remote Desktop Users 63 00:04:22,690 --> 00:04:23,020 Group. 64 00:04:23,890 --> 00:04:29,080 But Joe Smith, who was an admin that I have that's no longer with the company and has his credentials 65 00:04:29,080 --> 00:04:32,620 spread all over, these local groups will be removed from that group. 66 00:04:33,480 --> 00:04:38,590 And that's an easy scenario to handle with the preferences local users and groups feature. 67 00:04:39,510 --> 00:04:44,040 Now, even though it's a preference, users cannot override these, as I mentioned, unless they're 68 00:04:44,040 --> 00:04:47,850 a member of local administrators on their workstations or their server. 69 00:04:48,740 --> 00:04:54,560 This is just as good as any other policy because the operating system security protects against tampering 70 00:04:54,560 --> 00:04:56,360 of this kind of group membership stuff. 71 00:04:57,310 --> 00:05:02,620 So really cool capabilities around group membership control, local group membership control and group 72 00:05:02,620 --> 00:05:03,360 policy. 73 00:05:03,370 --> 00:05:07,240 And what I'm going to do next is give you a little bit of demo as to how this works.
