WEBVTT 00:01.800 --> 00:08.820 In this movie you're going to be taking a look at Lee Bell's otherwise known as security contexts. 00:08.820 --> 00:20.240 Let's begin if you remember what I told you only a few lessons ago SC Linux is all about the labels. 00:20.460 --> 00:29.010 Labels are added to all System objects files processes use ask directories everything gets a label each 00:29.070 --> 00:38.130 object can only have one label and every bell comprises the following four values user row type and 00:38.130 --> 00:42.570 level to view the label for different objects. 00:42.570 --> 00:50.580 All we need to do is tack on the option dash capital Z to most of the common commands that we already 00:50.580 --> 00:55.580 know for example to view the security context for my user account. 00:55.590 --> 01:00.230 All I have to do besides dash capital Zi for a file. 01:00.240 --> 01:03.770 I can go out and say Alice Rosa on Etsy. 01:03.960 --> 01:05.820 Let's use a group. 01:06.240 --> 01:12.050 And for my current vast process I can say P.S. dash Z. 01:12.180 --> 01:20.320 If we take a close look we can see that each of these commands gives us for cool on separated values. 01:20.550 --> 01:31.200 These values make up the SC Linux security context the first value is the user the next value is the 01:31.200 --> 01:32.820 row. 01:32.880 --> 01:35.130 After that we have the tie. 01:36.030 --> 01:39.100 And lastly we have the level. 01:39.690 --> 01:45.240 Most of the time we really use the level. 01:45.240 --> 01:56.820 So every object on the system gets labelled with a security context and this labels of used by the policy 01:56.880 --> 02:01.530 to make access control decisions and the next lesson. 02:01.530 --> 02:04.560 If you're going to take a look at policy types. 02:04.560 --> 02:05.100 Thank you.
