QUESTION:

You just received an alert that a critical server on your network is receiving traffic from various IP addresses and no longer has the capacity to handle the number of requests coming through – they are almost ten times the amount of normal traffic. What kind of attack is this and what are steps that can be taken during the preparation phase to prepare for this kind of incident?

This is a Distributed Denial of Service Attack. A few example steps that can be taken to in preparation include:

  • Monitor networks for unusual activity daily
  • Document your infrastructure
  • Establish an inventory of your critical assets and processes
  • Test DDoS response plan
  • Implement an incident response policy that all employees must read
  • Implement a security strategy
