Denial of Service (DoS) attacks aim to make services and systems unavailable to legitimate users . If these attacks are performed by multiple sources at the same time and for the same target, they are called Distributed Denial of Service (DDoS) attacks. This talk “Imma Chargin Mah Lazer” describes different types of (D)DoS attacks that are out in the wild and are seen on a daily basis by different corporations. Furthermore, a multi-layered strategy to mitigate such kinds of attacks has been presented within the talk. The speaker is Dr. Oliver Matula, an IT security researcher at ERNW who holds a PHD degree in physics. He presented the topic in a simple way which eases the delivery of information to audience of different technical levels and backgrounds.
