1 00:00:06,820 --> 00:00:10,190 - In the security operations center, or in the SOC, 2 00:00:10,190 --> 00:00:14,930 we need to quickly detect abnormal traffic, that's a given. 3 00:00:14,930 --> 00:00:19,230 Unfortunately, many different traditional detection methods 4 00:00:19,230 --> 00:00:22,540 take a lot of computational overhead, 5 00:00:22,540 --> 00:00:24,220 which will make it hard 6 00:00:24,220 --> 00:00:28,560 to meet the real-time requirement that we need, nowadays, 7 00:00:28,560 --> 00:00:32,520 especially to detect different sophisticated attacks. 8 00:00:32,520 --> 00:00:35,330 Now, there are many different studies and solutions 9 00:00:35,330 --> 00:00:38,640 that provide a distributed network traffic 10 00:00:38,640 --> 00:00:40,440 anomaly detection algorithm, 11 00:00:40,440 --> 00:00:43,820 based on a concept called the sliding window, 12 00:00:43,820 --> 00:00:45,140 which is, basically, 13 00:00:45,140 --> 00:00:49,650 through this sliding time, or sliding time-window, 14 00:00:49,650 --> 00:00:52,130 traffic anomaly detection will be limited 15 00:00:52,130 --> 00:00:53,970 to only the specific amount of time, 16 00:00:53,970 --> 00:00:57,730 so, the scope is a lot smaller. 17 00:00:57,730 --> 00:01:01,500 Now, this significantly reduced the amount of data analysis 18 00:01:01,500 --> 00:01:04,950 to improve the speed of anomaly detection, 19 00:01:04,950 --> 00:01:06,190 and to be able to scale, 20 00:01:06,190 --> 00:01:08,640 be able to actually reduce the need 21 00:01:08,640 --> 00:01:12,810 of all that overhead of computational analysis, 22 00:01:12,810 --> 00:01:16,240 and, basically, take advantage of this sliding time-window 23 00:01:16,240 --> 00:01:19,463 for that specific limited scope of time.
