Tom is an active member in IDEMA, IEEE, SMPTE, SNIA and other technical organizations. Dr. Michael Willett, Storage Security Strategist, Samsung. Recently, Dr. Willett was a Senior Director at Seagate Research, focusing on security functionality on hard drives, including self-encryption, related standardization, product rollout, patent development, and partner liaison. Currently, Dr. Willett serves as a consultant on the marketing of storage-based security. Presently, Dr. Willett is working with Samsung as a storage security strategist, helping to define their self-encryption strategy across Samsung s portfolio of solid-state storage products. Hussein Syed, Director of IT Security, Barnabas Health. Hussein has over 18 years IT experience of which 10 years has been in IT Security. He has a thorough understanding of health care business enablement (both clinical and business-driven) focusing on secure practice and compliance. In his role he has to remain technical and understands its impact on risk, workflow, patient care/satisfaction and physician/clinician enablement. Hussein has also participated in Gartner and NJHIMMS roundtable sessions on HIPAA/HITECH and IT Security. Copyright 2013 Trusted Computing Group 3

5 Increasing world-wide financial and legal consequences for data loss and data breaches Safe Harbor laws in most of the US and the EU for loss of devices with secured and encrypted data Trusted Computing Group (TCG) standards for notebook/portable computers (OPAL) and Enterprise Storage Devices using FIPS compliant AES 128 and 256 bit encryption Lower overhead encryption and decryption for SEDs than software encryption SEDs allow fast Crypto-Erase that sanitizes drive data before drive replacement, repair, de-commissioning, re-purposing and end of life Copyright 2013 Trusted Computing Group 5

6 Most major storage device companies provide SEDs Seagate, Western Digital, HGST (part of WD) and Toshiba offer portable and/or enterprise TCG encrypted HDDs Micron and Samsung provide TCG OPAL compliant SSDs There are special advantages for TCG encrypted SSDs Crypto-erase may be the most effective way to sanitize an SSD The overhead penalty for software encryption vs. self-encryption is even more significant for SSDs than HDDs Copyright 2013 Trusted Computing Group 6

7 Million Units Shipped High Median Low By 2017, all hard disk drives will be SED capable, with encryption integration into the controller (as a reference point, over 25% were SED enabled in 2011) Copyright 2013 Trusted Computing Group 7

10 All Drives eventually leave the data center IBM estimates 90% are still readable Why secure data? Increasing global regulations for data security PCI, HIPAA regulations require data privacy 46+ states have breach notification laws with encryption safe harbor Increasing consequences of non-compliance from privacy protection and breach notification laws Ponemon Institute estimates $194 for US company per compromised customer record in 2011; Average total per-incident cost of $5.5 Million. Privacy Rights Clearinghouse reports 607,234,229 records have been breached as of February 2013 Copyright 2013 Trusted Computing Group 10

11 The Problem Since 2005, over 345,124,400 records containing sensitive personal information have been involved in security breaches In 2008, the average cost of a data breach was $6.65 million per affected corporation ($202 per record) $6.65 Million Per Incident Reported Data Breaches Since February 2005 to Now # of reported breaches per month Feb-05 Apr-05 Jun-05 Aug-05 Oct-05 Dec-05 Feb-06 Apr-06 Jun-06 Aug-06 Source: Privacy Rights Clearinghouse Copyright 2013 Trusted Computing Group 11

13 Threat scenario: stored data leaves the owner s control lost, stolen, re-purposed, repaired, end-oflife, Compliance (Breach Notification) 46+ states have data privacy laws with encryption safe harbors New U.S. Federal and EU data breach legislation Data center and laptop drives are mobile (HDD, SSD) Exposure of data loss is expensive ($6.65 Million on average per incident 1 ) Obsolete, Failed, Stolen, Misplaced Nearly ALL drives leave the security of the data center The vast majority of decommissioned drives are still readable 1.

15 Transparency: SEDs come from factory with encryption key already generated Ease of management: No encrypting key to manage Life-cycle costs: The cost of an SED is pro-rated into the initial drive cost; software has continuing life cycle costs Disposal or re-purposing cost: With an SED, erase on-board encryption key Re-encryption: With SED, there is no need to ever reencrypt the data Performance: No degradation in SED performance Standardization: Whole drive industry is building to the TCG/SED Specs No interference with upstream processes ISSUE: Hardware acquisition (part of normal replacement cycle) Copyright 2013 Trusted Computing Group 15

16 Pre-boot Authentication AK Authentication Key DEK Data Encryption Key Correct AK? Clear Data Drive does NOT respond to Read or Write Reqs Hash AK No = Yes Clear AK decrypts DEK Unlock HDD DEK encrypts and decrypts User Data Hashed AK Encrypted DEK Encrypted User Data Copyright 2013 Trusted Computing Group 16

17 Stored Data Protection Should equipment be lost, data is not exposed All user data is always encrypted Encryption function cannot be turned off Immediate Data Erasure (Crypto-Erase) When drives are to be retired, relinquished or repurposed Data can be destroyed instantaneously Even if drive is inoperable Recommended by NIST (see SP Guidelines for Media Sanitization) Not Addressed Protecting data in flight Prohibiting unauthorized user access after drive is unlocked Copyright 2013 Trusted Computing Group 17

18 Performance Each SED encrypts all data transferred to it transparently and fast. As SEDs are added, the encryption performance scales linearly. No re-encryption necessary when external credentials (AKs) need changing Security No back doors No access without authentication resistant to evil maid attack All user data encrypted, always Encryption cannot be turned off by user; not exposed outside drive Crypto-Erase of data Manageability No OS or Master Boot Record modification Standard protocol, multiple sources - All drive manufacturers support TCG standard No interference with storage management functions: RAID, backup/restore, compression, de-dup, DLP Lower cost disposal, no hazardous waste created Copyright 2013 Trusted Computing Group 18

26 1. Purchase all new laptops and enterprise data storage with SED drives 2. Retrofit high-risk legacy machines with SED drives 3. Restrict access to stored sensitive data to machines with SED drives in early rollout 4. When adding more drives to array to the data center, use SEDs to avoid concerns for balancing encryption workloads 5. Phase in SEDs into the data center 6. Avoid or minimize the need for data classification 7. Be aware of and accommodate other data security contexts Copyright 2013 Trusted Computing Group 26
