1 00:00:03,050 --> 00:00:05,960 In this demonstration, we will work with gentlemen. 2 00:00:06,800 --> 00:00:10,760 You will look at how you can audit Intel and usage in the server environment. 3 00:00:11,660 --> 00:00:17,240 Following this, you will configure Intel M security to make sure that Intel in version two is enforced 4 00:00:18,110 --> 00:00:20,030 when it comes to working with Intel Elm. 5 00:00:20,060 --> 00:00:25,160 It's important to note that many old devices in your environment could still use those old authentication 6 00:00:25,160 --> 00:00:25,880 protocols. 7 00:00:26,780 --> 00:00:29,910 Some of those devices might support Intel ARM Version two. 8 00:00:30,770 --> 00:00:34,340 However, it might only support it after you actually configure it. 9 00:00:35,240 --> 00:00:40,580 So a word of caution don't simply disable intel and version one without knowing which devices are using 10 00:00:40,580 --> 00:00:40,730 it. 11 00:00:41,600 --> 00:00:44,060 And how would you know which devices are using it? 12 00:00:44,960 --> 00:00:47,630 Well, the first step is to perform auditing. 13 00:00:48,410 --> 00:00:53,330 When you enable and tlm auditing, you have the ability to look at your audit logs and look for event 14 00:00:53,330 --> 00:00:54,980 ID 4624. 15 00:00:55,850 --> 00:00:59,510 You'll see a sample of event ID 4624 on your screen. 16 00:01:00,350 --> 00:01:04,070 In the sample, you'll notice that the log on type is logged on type three. 17 00:01:04,940 --> 00:01:09,650 This means that the user computer has logged on to the destination computer from the network. 18 00:01:10,520 --> 00:01:13,700 The next piece that's highlighted is the authentication package. 19 00:01:14,600 --> 00:01:18,320 Here we can see that anti alarm was used as the authentication method. 20 00:01:19,220 --> 00:01:22,710 The next section to look at is the package name and TLM only. 21 00:01:23,570 --> 00:01:27,170 In this example you'll notice that in tlm version two was used. 22 00:01:28,040 --> 00:01:33,140 However, if it showed L, M, or NTL and V one, then you know that either the land manager or in tlm 23 00:01:33,140 --> 00:01:34,280 version one was used. 24 00:01:35,180 --> 00:01:39,380 Now you'll go ahead and enable the deepest level of intial auditing possible. 25 00:01:40,220 --> 00:01:43,670 And to do this, you're going to navigate to group policy management. 26 00:01:44,550 --> 00:01:49,620 And since we want to enable this in tlm auditing across the domain, you will go ahead and edit the 27 00:01:49,620 --> 00:01:51,000 default domain policy. 28 00:01:51,850 --> 00:01:56,680 And within the default domain policy, you're going to navigate to policies, slash windows settings, 29 00:01:56,680 --> 00:02:00,610 slash security settings, slash local policies, slash security options. 30 00:02:01,480 --> 00:02:06,010 Within security options, there are three group policy settings that we are going to look at. 31 00:02:06,880 --> 00:02:09,970 The first one is the ordered incoming intel and traffic. 32 00:02:10,860 --> 00:02:17,730 Then we will look at Audit Elm authentication in this domain and we will look at outgoing intel traffic 33 00:02:17,730 --> 00:02:18,810 to remote servers. 34 00:02:19,680 --> 00:02:23,430 So let's start with the first one audit incoming intel m traffic. 35 00:02:24,310 --> 00:02:29,530 In this setting, you have three possible values to define the first being disable, which of course 36 00:02:29,530 --> 00:02:30,880 disables the policy. 37 00:02:31,750 --> 00:02:34,870 The second one, which is enable auditing for domain accounts. 38 00:02:34,930 --> 00:02:39,790 When this is enabled, events will be logged for Intel and pass through authentication requests only. 39 00:02:40,640 --> 00:02:46,280 The next setting, which is enable auditing for all accounts, will log events for all anti alarm authentication 40 00:02:46,280 --> 00:02:46,850 requests. 41 00:02:47,780 --> 00:02:53,300 Since we want to enable the deepest level of TLM auditing to ensure that we don't break any collectivity. 42 00:02:53,330 --> 00:02:55,790 We will select enable auditing for all accounts. 43 00:02:56,690 --> 00:02:57,920 You'll click on okay. 44 00:02:58,730 --> 00:03:03,680 And now you'll move on to the next setting, which is audit and TLM authentication in this domain. 45 00:03:04,520 --> 00:03:08,990 And within this setting we're going to enable all since you need to ensure that you are auditing all 46 00:03:08,990 --> 00:03:10,520 and tlm authentication. 47 00:03:11,390 --> 00:03:17,780 You'll click on okay, now let's move on to the next setting which is outgoing in tlm traffic to remote 48 00:03:17,780 --> 00:03:18,290 servers. 49 00:03:19,160 --> 00:03:24,350 And this group policy allows you to deny or audit outgoing inter-island traffic from a computer running 50 00:03:24,350 --> 00:03:28,670 Windows seven or later to any remote server that runs a Windows operating system. 51 00:03:29,540 --> 00:03:31,070 So you will click on okay. 52 00:03:31,880 --> 00:03:35,090 And now you have successfully enabled nt tlm auditing. 53 00:03:35,960 --> 00:03:40,850 Now in a real world scenario, you would leave this group policy active for some time, perform auditing 54 00:03:40,850 --> 00:03:45,740 on the event logs, and ensure that you have a clear picture of what devices in your organization uses 55 00:03:45,740 --> 00:03:51,830 anti tlm version one once you have isolated the ones that use in tlm version one and if they cannot 56 00:03:51,830 --> 00:03:56,540 be upgraded, you can then use a different group policy to specifically target those devices that can 57 00:03:56,540 --> 00:03:58,190 work within TLM version two. 58 00:03:59,000 --> 00:04:04,160 So once you have audited your log on events and found that there are no devices that are using old authentication 59 00:04:04,160 --> 00:04:10,520 protocols, you are then ready to enforce in TLM Version two in order to enforce in tlm version two, 60 00:04:10,520 --> 00:04:15,590 you need to modify one policy which is network security LAN manager authentication level. 61 00:04:16,490 --> 00:04:19,610 This setting has six levels and they are counted from zero. 62 00:04:20,450 --> 00:04:23,900 So at zero one, two, three, four, five. 63 00:04:24,770 --> 00:04:29,900 So when this is hardcoded on the registry, you would see a registry security level starting from zero 64 00:04:29,900 --> 00:04:32,720 and zero being sent Elm and Intel and responses. 65 00:04:33,650 --> 00:04:35,540 So what do each of these settings mean? 66 00:04:36,380 --> 00:04:41,360 While the first one is obvious in which you are only hard coding your authentication level to work with 67 00:04:41,360 --> 00:04:47,840 LAN manager and into Elm, the second one enables the use of Intel and V two session security only if 68 00:04:47,840 --> 00:04:48,710 it's negotiated. 69 00:04:49,580 --> 00:04:53,510 The next one drops LAN manager and only uses Intel M version one. 70 00:04:54,350 --> 00:04:57,410 The one after that starts to introduce Intel and version two. 71 00:04:57,530 --> 00:05:02,510 However, the domain controller will still accept Elm and Intel in version one authentication. 72 00:05:03,350 --> 00:05:09,740 The next setting starts to completely refuse LAN manager and the most secure settings starts to refuse 73 00:05:09,740 --> 00:05:15,830 LAN Manager and Intel Version one Best practices dictate that you should start with a security level 74 00:05:15,830 --> 00:05:19,160 of three, so that would be zero one, two and three. 75 00:05:20,060 --> 00:05:25,070 So the authentication level to start with as you start to enforce in TLM version two is the setting 76 00:05:25,190 --> 00:05:27,590 which is send Intel and V two response only. 77 00:05:28,460 --> 00:05:34,040 What this does is it enables Intel and V two as default, but still allows a fallback to LAN manager 78 00:05:34,040 --> 00:05:35,330 in Intel m version one. 79 00:05:36,170 --> 00:05:41,120 Once you configure this, you'll notice that there is a warning which will take you to a microsoft article 80 00:05:41,120 --> 00:05:44,450 which dictates the possible impact of configuring this setting. 81 00:05:45,290 --> 00:05:49,970 Since you need to ensure that Intel and V two is starting to be used as a default, you will accept 82 00:05:49,970 --> 00:05:52,310 this change and allow the setting to be configured. 83 00:05:53,180 --> 00:05:58,850 The next step from here would be to perform auditing again, and the reason for performing additional 84 00:05:58,850 --> 00:06:03,890 auditing is to see which devices are still using LAN manager and eliminate them from the environment. 85 00:06:04,790 --> 00:06:09,350 If there are no devices that are using LAN manager anymore, you can then move to the next level of 86 00:06:09,350 --> 00:06:14,180 four and perform auditing again and pretty much repeat the same process until you get to the most secure 87 00:06:14,180 --> 00:06:14,990 level of five. 88 00:06:15,850 --> 00:06:17,680 And that is when the system refuses. 89 00:06:17,680 --> 00:06:19,450 Land Manager and anti elm. 90 00:06:20,320 --> 00:06:24,040 So what if you wanted to remove anti Elm authentication completely? 91 00:06:24,880 --> 00:06:30,190 Well, the two settings that are defined here under restrict into elm incoming into elm traffic and 92 00:06:30,190 --> 00:06:31,330 restrict into Elm. 93 00:06:31,330 --> 00:06:36,280 And TLM authentication in this domain is what you could configure to completely stop into Elm. 94 00:06:37,120 --> 00:06:41,770 But again, a word of caution is to make sure that you have audited the environment to ensure that your 95 00:06:41,770 --> 00:06:47,080 devices can support another authentication protocol such as Kerberos instead of 90 Elm. 96 00:06:47,950 --> 00:06:52,450 These settings are extremely powerful and if they are configured incorrectly, you could pretty much 97 00:06:52,450 --> 00:06:56,500 break your environment and have endless issues with devices that do not authenticate. 98 00:06:57,370 --> 00:07:01,780 So best practice is to make sure that you perform a deep level of auditing to ensure that you have a 99 00:07:01,780 --> 00:07:06,460 clear picture of any impacted devices as you define the settings for restricting into ELM.
