Update on Testing

First four weeks of testing

As of April 7, 2014

Distributed denial of service ddos
Distributed Denial of Service (DDOS)

  • On March 27, CETE was hit with the first distributed denial of services (DDOS).

    • Originated outside of the United States

    • A DDOS results in such large amounts of data sent to server that it prevents legitimate uses of that server.

    • Issue was reported at 7:15am and mitigated by 12:50pmthat same day.

    • Eliminating IP addresses from offshore locations curbed the effects of this first attack.

A second ddos attack
A Second DDOS Attack

  • On Tuesday, April 1 CETE was hit by a second DDOS attack.

  • This second, separate attack was 100X stronger than the one from the previous week

  • After the second attack, CETE enlisted the services of a contractor specializing in mitigating the effects of a DDOS.

  • With contractor support, CETE was able to identify traffic that was “malicious.” Initially, some legitimate school traffic was misidentified.

Important clarifications and assurances
Important Clarifications and Assurances

  • No student record was ever in jeopardy.

  • A DDOS is an incoming surge only.

  • No data has been compromised.

  • CETE is continuing to strengthen security and will work this summer to create redundancies to avoid the effects of this type of attack in the future.

  • An external security audit of KITE will be conducted by Fall 2014 to confirm security of data.
