00:00:01,610 --> 00:00:08,390
Welcome to another lecture on operating system security this time we'll examine the mechanisms of authentication

2
00:00:08,390 --> 00:00:13,100
and authorization and talk about managing user accounts and resource access in a system

3
00:00:19,480 --> 00:00:24,130
this module will teach you how to differentiate between authentication and authorization.

4
00:00:25,900 --> 00:00:33,130
The two terms should not be confused with user identification.

5
00:00:33,140 --> 00:00:38,060
We'll find out which types of passwords are secure and which are not and carefully examine the methods

6
00:00:38,060 --> 00:00:40,020
for storing user passwords in Windows

7
00:00:43,360 --> 00:00:50,220
remote user authentication protocols will be used will show you protocols used for proving identity

8
00:00:50,220 --> 00:00:51,730
of remote computer users

9
00:00:56,400 --> 00:01:01,720
will also tell you why one of the types of credentials stored by Windows cached credentials is not putting

10
00:01:01,720 --> 00:01:04,920
system security at risk as the popular myth would tell you

11
00:01:08,290 --> 00:01:10,650
the Kerberos protocol will be examined.

12
00:01:12,160 --> 00:01:16,460
This is the safest protocol for authenticating users in Microsoft Windows networks

13
00:01:20,120 --> 00:01:23,600
will also try to crack different kinds of passwords used by Windows users

14
00:01:26,570 --> 00:01:32,060
and then we'll also try to give you an answer to the questions on authorization mechanisms such as What

15
00:01:32,060 --> 00:01:36,460
is the difference between role based access control and discretionary access control

16
00:01:39,990 --> 00:01:45,240
only the module will cover the purposes and applications of a new access control system introduced in

17
00:01:45,240 --> 00:01:52,750
Windows Vista which was an implementation of the belt loop Adullam model.

18
00:01:52,780 --> 00:01:53,790
See you in the training.
