What is Distributed Denial of Service Attacks (DDoS)?

The hacker attacks a single target “the flood of incoming messages to the target system essentially forces it to shut down, thereby denying reduce to the system to legitimate users”. DDoS use lots of machines to attack unlike DoS, silencing the internet!

What is a Denial Service Attack (DoS)?

This attack makes the computer resource unavailable to its users; moreover, they also force the targeted computer to reset.  Attacker will be able to prevent the users to stop accessing their emails, websites, etc, etc.

The main difference between DDoS attack vs. DoS attacks are that the target server will be overload by thousands of requests in the case of former as opposed to just one attacker in the case of the latter.

The video basically talks about the attacks, and what we can do to prevent them.  They also talk about the 9 hour outage that affected 95% of China.  The message they are trying to put out there is that it’s a serious issue that people are not aware of it.

How to stop these attacks?

1. Setup machine batter
2. Dynamic rerouting
3. Scrubbing—filter!!
4. Server Optimation

Statistics:

72% have experienced national network filtering.

62% have experienced DDoS attacks

39% have experienced intrusion

32% have experienced defacement

I mostly enjoyed listening to Hal Roberts; he seemed more serious about this topic than Ethan Zuckerman. Plus, Zuckerman just looked annoying—he is having a important interview/ meeting and he is eating food and drinking his “diet Pepsi”—I didn’t think that it was professional of him to do that! Fortunatley, Hal ROCKED the interview!
