You will need log file reporting tools to help you determine:
• If you have a breach—unauthorized access, disclosure,
leak of information
• If the breach is consequential enough to report—what
kind of information was exposed, for how long, how many
affected, was it anonymized/encrypted, etc.
• What steps you will need to take to mitigate—take
systems or users off line, shunt access, create sink
holes, etc.
So What Can You Do to Prepare?
Some essential tools will help

14. © 2017 SPLUNK INC.
▶ At Splunk, our employees are our canaries in the
coal mine
▶ You can’t notify customers, DPAs, or consumers, if you
don’t know there is a problem
▶ No DPO/CPO/CISO/CIO can be everywhere, all the
time
▶ Loss, destruction, leakage, unauthorized access—they
can happen anywhere, not simply at your firewall
▶ You need everyone to play their part
You Will Also Need Training

At Splunk, We Are Focusing On Three Key Areas
All designed to get us ready for May 2018

16. © 2017 SPLUNK INC.
1. Security and Privacy are team sports—rally
your team (Security/IT/Legal/HR/Marketing/Customer
Relations)
2. Training and IR Plan updates can be done easily
and quickly—an ounce of prevention is worth
a pound of cure
3. Don’t get overwhelmed, it won’t help
4. Put together a workable—not a perfect—plan
and get going
5. Start with the easy stuff first—build team
confidence
Don’t let perfection be
the enemy of the
good—GDPR is here to
stay—plenty of time
ahead to improve
