• Encryption basics• Importance of encryption• Encryption solutions

– Laptops/Desktops– USB/CD– Email/Cloud

What is Encryption?• Encryption is a security process that scrambles

information. It changes information from a readable form into something that can not be read unless you have the key.

This:

Rmvtu[yopm dhqht3w 3qtq isem ze mrxephlebl oermzq

…so ONLY the person with the decryption key or password can read the information

Becomes something like this:

Encryption changes data into an unreadable format

Encryption vs. Passwords• Having a password does not necessarily mean

something is encrypted.– Passwords by themselves do not scramble the information.

• If something is only “password protected,” it is not enough protection - someone could bypass the password and read the information.

Original Password Protected Encrypted

Why is Encryption Important?

Encryption protects confidential information and helps keep it private!

• Statistics show that as many as one in ten laptops will be stolen or lost from an organization over the lifetime of each computer

• Laptops and USB devices can be easily lost or stolen

Why is Encryption Important? (Cont’d)• HIPAA – Health Insurance

Portability and Accountability Act to ensure confidentiality of patient health information

• Regulatory efforts impose stiffer fees and fines in the event that a breach occurs and steps are not taken to appropriately protect sensitive data

• Breach Notification Laws - require notification if information was not encryptedEncryption technologies can assist with ensuring the confidentiality of patient health information and also serve as a strong measure of protection against

today’s commonly anticipated threats, such as unauthorized access, modification, and disclosure.

HIPAA Fines

• April, 2014 - OCR levies $2 million in HIPAA fines for stolen laptops: – $1,725,220 against Concentra Health Services for

an unencrypted laptop that had been stolen from one of Concentra Health Services facilities.

– $250,000 against QCA Health Plan, Inc. of Arkansas after an unencrypted laptop containing personal health information for 148 people was stolen from an employee's car.

High Risk Confidential Information:

A person’s name or other identifier, in conjunction with:

• Personally-identifiable Medical Information• Dates (birth date, admission date, discharge date, etc.)• Social Security number• Driver’s license• State ID or Passport number• Biometric information• Medical Record # (MRN)• Health Insurance #

Other Confidential Information:

• Human Subjects information• HR Records• Credit Card Information

• Whatever you considers confidential

Good Security Standards follow the “90 / 10” Rule:• 10% of security safeguards are technical• 90% of security safeguards rely on the computer user

(“YOU”) to adhere to good computing practices

The lock on the door is the 10%. You remembering to lock, check to see if it is closed, ensuring others do not prop the door open, keeping control of keys is the 90%.
