1 00:00:08,500 --> 00:00:17,830 To ensure a proper live function and PGI environment you must configure the A and C DP certificate extensions 2 00:00:18,160 --> 00:00:19,790 for rich C. 3 00:00:19,900 --> 00:00:29,050 This will ensure that the picky in wild moment encounters minimal failures when applications or services 4 00:00:29,170 --> 00:00:36,620 attempt to validate the trust chain or revocation status of a certificate. 5 00:00:36,730 --> 00:00:43,410 The following list describes the purpose of a and CTP addresses. 6 00:00:43,450 --> 00:00:54,590 We have a addresses which are the Urals that tell a certificate where a fire the location of the C certificate 7 00:00:55,160 --> 00:01:04,610 AAA addresses are necessary so that applications and services that use a certificate can establish both 8 00:01:04,910 --> 00:01:14,810 the well validity of the C and a trust chain to see that the verifier explicitly trusts. 9 00:01:14,840 --> 00:01:24,470 If it does not explicitly trust the C that directly issued the certificate and we have city B addresses 10 00:01:24,660 --> 00:01:31,730 so deeply addresses are there your rules that tell a certificate where a fire or the location of the 11 00:01:32,000 --> 00:01:42,190 CRL let the C maintains Sydney B addresses are necessary so that application sound services that use 12 00:01:42,200 --> 00:01:48,130 a certificate can establish their revocation status of a certificate. 13 00:01:49,250 --> 00:01:59,120 Each certificate that you issue from your receipt contains the A and C DPR rails that you configured 14 00:01:59,270 --> 00:02:10,760 on the seat at the time the CIA issued the certificate a and Cindy DP extensions must each contain at 15 00:02:10,760 --> 00:02:21,320 least one accessible your role or the verifier might assume that the certificate is not valid rendering 16 00:02:21,320 --> 00:02:24,070 the certificate unusable. 17 00:02:24,110 --> 00:02:33,630 Please know that your rules for a and city B locations can be issued a B or file transfer protocol to 18 00:02:33,630 --> 00:02:40,730 p or light way in Europe to access protocol old DEP or file addresses. 19 00:02:41,730 --> 00:02:46,230 Now and c the p published in consideration. 20 00:02:46,620 --> 00:02:56,070 If you are using an enterprise C the air and CTP extension welders are automatically configured so that 21 00:02:56,340 --> 00:03:07,280 the C certificate and CRL is available in the ADA d d s configuration partition that replicates to old 22 00:03:07,280 --> 00:03:11,490 domain controllers in the ADT as forest. 23 00:03:11,490 --> 00:03:21,540 However if you want to deploy M off line or standalone C or if you will use certificate that C outside 24 00:03:21,540 --> 00:03:31,600 of your radius environment issues you must consider off line or standalone C because of line and stand 25 00:03:31,600 --> 00:03:42,840 alone CS do not integrate with HDD you will need to ensure a and c p accessibility manually by publishing 26 00:03:42,840 --> 00:03:53,820 their offline or standalone C certificate and CRL to 80 days by using the cert you still command. 27 00:03:53,820 --> 00:04:04,530 This provides the same benefit as an enterprise C and makes a C B yourself accessible to a D D s clients 28 00:04:04,830 --> 00:04:13,950 throughout the forest but you must manually publish the information and manually configure the C extensions 29 00:04:14,250 --> 00:04:16,970 with the correct old DEP your row. 30 00:04:17,520 --> 00:04:26,580 Please note that besides configure and c DP and AAA publication points you should also make sure that 31 00:04:26,880 --> 00:04:39,010 the CRL is valid and on line S.A. will automatically renew the CRL periodically but an off line C will 32 00:04:39,010 --> 00:04:39,770 not. 33 00:04:40,150 --> 00:04:47,610 If the fly in C0 expires revocation checks will fail to prevent failure. 34 00:04:47,620 --> 00:04:55,660 Make sure that you configure the will lead it to period for the off line CCR rail to build long enough 35 00:04:56,870 --> 00:05:05,930 and set a reminder to turn the C on and issue a new cereal before the old one expires. 36 00:05:07,750 --> 00:05:16,690 Now clients that are not domain members internal clients that are not domain members will not be able 37 00:05:16,690 --> 00:05:29,040 to access the A or Sydney P L DEP yourselves which reference the HDD configuration partition in this 38 00:05:29,040 --> 00:05:38,250 case you should place the C certificate and CRL on an internally accessible Web server and configure 39 00:05:38,300 --> 00:05:44,780 a well it is to the BRL for the A and C to be extensions. 40 00:05:44,820 --> 00:05:54,480 You might also choose to use FTB or file your rails but it is recommended that you use only a TTP in 41 00:05:54,480 --> 00:06:00,870 this scenario for maximum interoperability and flexibility. 42 00:06:00,870 --> 00:06:09,030 As for external clients clients that are external to your network including domain clients on an external 43 00:06:09,030 --> 00:06:19,320 network will also be able to access the a steady build up your Ls which reference your internal HDD 44 00:06:19,320 --> 00:06:20,520 environment. 45 00:06:20,520 --> 00:06:27,810 Additionally they might not be able to access internal issue to be your health without a virtual private 46 00:06:27,810 --> 00:06:39,530 network or repair or direct access connection if external clients need to validate cert that your internal 47 00:06:39,560 --> 00:06:43,970 CIA issued you might need to take the following actions. 48 00:06:43,970 --> 00:06:51,320 You might need to publish the internal issue TTP your health externally by using the Windows Server 49 00:06:51,350 --> 00:07:01,000 2016 web application proxies servers of the remote access role you can optionally use a third party 50 00:07:01,010 --> 00:07:03,460 to a rigorous proxy solution. 51 00:07:03,590 --> 00:07:13,880 If the internal and external your rules do not match and you will need to configure an additional a 52 00:07:13,970 --> 00:07:24,200 or Cindy page to BRL on this see it and in other action you might need external clients that do not 53 00:07:24,200 --> 00:07:34,410 belong to your HDD domain will need to have your C certificate manually imported to the trusted route 54 00:07:34,410 --> 00:07:42,360 certification authorities or an intermediate certification authorities stores. 55 00:07:42,380 --> 00:07:50,540 This might be necessary as the external client will not otherwise Trust Certificates that your internal 56 00:07:50,800 --> 00:07:52,150 CIA issue. 57 00:07:54,110 --> 00:08:04,430 Please note that the order in which you list the DP and AAA your rails is important because certificate 58 00:08:04,430 --> 00:08:13,640 change in engine so the your Urals sequentially if your certificates are mostly used internally in an 59 00:08:13,730 --> 00:08:23,010 80 days environment place the hold up your first and the list order any other your else based on the 60 00:08:23,280 --> 00:08:28,380 likelihood that your URL will be available to internal or external clients. 61 00:08:29,460 --> 00:08:40,170 Another consideration you have if you if you decommission the AAA or SDP your else on the issued certificates 62 00:08:40,530 --> 00:08:48,380 by removing them from the sea you should ensure that also difficult that container decommissioned your 63 00:08:48,390 --> 00:08:59,360 rail have either expired been revoked or contained an additional your rail that is still valid and accessible.
