  1. Encryption Option Overview For VERITAS NetBackup

  2. Lost backup tapes and potential fraudulent activity have real financial costs Violates the internal control process of Sarbanes-Oxley Act Financial losses from fraud (e.g., settlements, monitoring services) Corporate brand, public relations impact, and customer confidence impact Concentrated amount of data on highly portable backup tapes Impact of tape loss 2 - 5x greater than online breaches / stolen hardware1 Multiple copies of unencrypted backup tapes increases exposure Backup / tape service providers can and do lose data Iron Mountain had 4 instances of lost tapes (Jan – May 2005) Iron Mountain recommends encryption of customer data Public disclosure of data loss impacts your company California law requires any company with a California customer record to report loss of data that comprises privacy 22 other states considering legislation similar to California Why Encrypt Backups? (1) Based on reported data losses Jan-May 2005 – www.privacyrights.org

  3. Recent loses of backup tapes Reported lost backup tapes Jan. – May 2005 "Very few people encrypt backup tapes, which means that they rely on the security of the backup and off-site rotation process." Jon Oltsik, senior analyst, information security, Enterprise Strategy Group An April 2005 survey of 322 IT professional revealed that more than 60% of companies across 10 industry segments never encrypt their backup data. Enterprise Strategy Group, April 2005

  4. Risks from comprimised or lost personal data • Financial Loss or Fraud • Affects company or government agency AND individuals (tax payers) • Institutional Credibility and Responsibility Hypothetical Cost Estimate 1 reference point: ChoicePoint spend $2 million to notify 135,000 customers * Because of their density and portability, the number of records lost with backups tapes has been substantially higher than online security breaches.

  5. Where to start with backup encryption • Common themes for thinking about backup security • Control and protection of data • Access to local and backup data • Ensuring that backups of critical data are maintained • Target data for encryption • Customer data or other content with private data (e.g., forms with a social security number only) • Intellectual property • Sensitive corporate and financial data • Understand regulations or laws that impact you • Health Information Portability Act (HIPPA) & Sarbanes-Oxley • California Senate Bill 1386 – disclosure of security breach

  6. NetBackup Encryption Option Overview Integrated with NetBackup • No additional software, hardware, or training • Easy to deploy based on existing policies Encryption applied at source (client) • Protect heterogeneous clients, applications, or databases • Mitigates risk at other storage and hardware points Multiple bit levels and ciphers for encryption Choose appropriate level of encryption for your needs

  7. How a backup works • Client takes latest key from the keyfile on the client (keyfile created using a passphrase). • Client creates an “encryption tar header” (not encrypted) which contains checksum of key & cipher. • Client writes the file data encrypted with key using the cipher defined. • Client writes the file data encrypted with key & cipher • Backup image on server includes a flag indicating an encrypted backup (also identified through standard NetBackup Reports). Vault End-to-end security Encryption at 40, 56, 128, or 256-bit level NetBackupclient NetBackupserver Tape or Disk

  8. How a restore works • Media Server determines from the backup image if whether the backup was encrypted • Media Server sends file names, attributes, and encrypted file data to the client to be restored • Client reads encryption tar header & compares the checksum in the header with checksums of the keys in the keyfile. If a match occurs that key will be used to decrypt the file data. • File(s) are decrypted and restored if a key & cipher are available. Otherwise an error message is generated. Vault End-to-end security NetBackupclient NetBackupserver Tape or Disk

  9. Encryption Option - Details • NetBackup client support • All client platforms** released with NetBackup • Database and application agent support • DB2, Informix, Oracle, Microsoft SQL Server • SAP, Microsoft Exchange and SharePoint Portal Server, Lotus Notes • Encryption levels and ciphers **Encryption is not available for NetBackup clients running NetWare

  10. Keyfile Management • A keyfile is required to restore encrypted data • Keyfile management and encryption policies should be clearly defined across the organization regardless of whether software or hardware is used for encryption • In the event of a lost keyfile, NetBackup can generate a new one if the user knows the pass phrase used to create the keyfile associated with the backup • For keyfile management NetBackup recommends either: • Manual Retention: Writing successive pass phrases on paper and placing in a secure location • Automatic Retention: Create a non-encrypted policy to backup client keyfiles to a separate and secure location • Minimize complexity behind pass phrase and keyfile management

  11. Summary • Encrypting data is far less costly than the resource use and money associated with data loss • Backup tapes can be stolen or lost regardless of the physical location where they reside • Software encryption option available today for NetBackup: • Centralized deployment to clients with standard NetBackup process • Easy to target data for encryption through use of policies • Cost effective to deploy on a per client basis as needs dictate • Customers have a choice of ciphers (AES, DES, Blowfish) and bit levels (40, 56, 128, 256) • Security of sensitive backup data required by law in some industries
