By now, you have probably heard that sites including Twitter, Spotify, and Amazon (to name a few) experienced outages a couple of weeks ago in what appears to have been a DDoS attack. Dyn, which manages website domains and routes internet traffic, experienced two distributed denial of service attacks on its DNS servers, according to CNN Money. Services were restored, however, Dyn was again monitoring an attack against its DNS server hours later. "We have begun monitoring and mitigating a DDoS attack against our Dyn Managed (Domain Name System) infrastructure. Our Engineers are continuing to work on mitigating this issue," Dyn said on its website at 11:52 a.m. ET., Friday, October 21st.
So, what exactly is a DDoS attack and how can your company avoid such an attack?
