1 00:00:00,060 --> 00:00:08,910 So the next one we're going to look at tonight is it is not, it cannot and it is Ronald Reagan protocol 2 00:00:09,480 --> 00:00:13,260 that means we can run into another computer in my computer. 3 00:00:13,290 --> 00:00:14,310 OK, that's fine. 4 00:00:14,700 --> 00:00:22,900 And the poverties, you can log on to the system and can access TerraMar so that you can log into it 5 00:00:23,850 --> 00:00:30,510 and we can get the terminal, which will be the common problem, and then it runs on the punditry. 6 00:00:31,680 --> 00:00:36,200 So you need to access the Internet service on the computer using this portability. 7 00:00:36,600 --> 00:00:37,950 And the command is very simple. 8 00:00:37,950 --> 00:00:46,100 Can access the IP address you want to connect to and the biggest disadvantage of entities. 9 00:00:46,230 --> 00:00:50,520 It sends the packets in plain text format that I can easily see. 10 00:00:50,640 --> 00:00:51,520 Doesn't seem right. 11 00:00:51,540 --> 00:00:59,580 So if there is any attacker in our network, he can easily see this tiny cracking packets and can see 12 00:00:59,580 --> 00:01:00,800 the data inside that. 13 00:01:01,110 --> 00:01:06,140 So inside the packet, using the login credentials, an attacker can see those currencies. 14 00:01:06,400 --> 00:01:10,440 You see the disadvantage of net, which is plaintext protocol. 15 00:01:11,870 --> 00:01:16,620 But don't think in modern days no one is going to use the Internet. 16 00:01:16,910 --> 00:01:24,170 But remember, in my college I have studied from 2016 to 2020, there is Internet. 17 00:01:24,350 --> 00:01:33,590 They had the old Ubuntu server, so it's OK server and they are using the Internet for remote regions. 18 00:01:34,340 --> 00:01:38,540 And we we use this for the need for programming purposes. 19 00:01:39,050 --> 00:01:45,410 So you can imagine even a bigger Nasution or a small company or a college. 20 00:01:46,040 --> 00:01:49,670 If they're using the Internet, then it's not safe. 21 00:01:50,630 --> 00:01:53,630 So just do not agree to any protocol. 22 00:01:53,640 --> 00:02:02,410 Just learn everything and also learn some security measures when you are going to implement a new protocol.
