1 00:00:00,180 --> 00:00:06,580 Denial of service means sending a huge number of packets from the front lines of combat escort service. 2 00:00:06,960 --> 00:00:13,140 So normally this is another computer is a Web server running on somewhere around the world and running 3 00:00:13,140 --> 00:00:13,770 a website. 4 00:00:13,920 --> 00:00:21,410 And what attacker does is he will send a huge number of packets from the system to the Web server. 5 00:00:21,420 --> 00:00:24,050 So Web server cannot handle those many requests. 6 00:00:24,360 --> 00:00:26,550 And what it does is it will crush us. 7 00:00:26,910 --> 00:00:28,350 That's called the General Service. 8 00:00:28,350 --> 00:00:37,350 And sometimes, even if it's said the website isn't even in the business, you can see that Amazon website 9 00:00:37,350 --> 00:00:44,330 is slow or crashed because it's because a lot of traffic is coming to the server. 10 00:00:45,180 --> 00:00:49,530 And if this attack is performed with many computers, then it's called the security service. 11 00:00:49,830 --> 00:00:56,870 That means you're not within your service already sending huge packets from one computer. 12 00:00:56,880 --> 00:01:01,960 But if it is performed from any other company, then it is called the dinner service. 13 00:01:02,130 --> 00:01:04,010 So these black attackers come. 14 00:01:04,290 --> 00:01:11,160 We will do the dinner service again to some particular tradition or web server. 15 00:01:11,490 --> 00:01:18,180 So the main intention is to crash the Web server and make sure that the website is not available for 16 00:01:18,180 --> 00:01:18,740 some people.
