  • Encryption Information Forum Theresa A. Masse, State Chief Information Security Officer Department of Administrative Services Enterprise Security Office
  • Agenda
    • Encryption overview
    • Agency Panel
      • Oregon Department of Transportation
      • Oregon Employment Department
      • Oregon Lottery
    • Statewide Contracts
    • Q&A
  • Encryption Overview
    • Richard Woodford, Security Analyst
    • Enterprise Security Office
    • Department of Administrative Services
  • What is encryption?
    • “ In cryptography , encryption is the process of transforming information (referred to as plaintext ) using an algorithm (called a cipher ) to make it unreadable to anyone except those possessing special knowledge, usually referred to as a key .”
    • -Wikipedia (2008)
  • Need for Encryption …
    • Keep confidential information safe
    • Prevent exposure of information while in transit across an unsecure medium
    • Prevent exposure of information when a storage device is lost or stolen
    • Oregon Identity Theft Protection Act (Senate Bill 583) “safe harbor”
    • Due care
  • Oregon Consumer Identity Theft Protection Act
    • Senate Bill 583 (2007 Legislative session)
      • “ … one or more of the following data elements, when the data elements are not rendered unusable through encryption”
        • First name, last name
        • Social Security number, drivers license number, passport, financial account number, credit card number
  • “ Safe Harbor”
    • What’s good enough?
    • VJKU KU GPETARVGF
      • Cipher – alphabetically shifted
      • Key – +2
    • SB 583 does not specify strength
    • Reasonable care
      • “ Strong encryption” – 128-bit
      • Common minimum standard is FIPS 140-2 (see http:// csrc.nist.gov )
  • Other Drivers
    • All applicable regulations should be examined for requirements
      • HIPAA
      • Payment Card Industry (PCI) requirements
      • Sarbanes-Oxley
      • Statewide policies
        • Information Asset Classification
        • Transporting Information Assets
        • Controlling Portable and Removable Devices
      • Department policies
  • Other Drivers
    • Other considerations
      • Mitigation costs
      • Public trust
  • When to Use Encryption
    • In any case where data could be at risk from theft or eavesdropping
      • Wireless networks
      • Transmitting data over public network (e.g. the Internet)
        • Web pages (SSL)
        • E-mail
      • Data at Rest
        • Portable devices
          • Laptops
          • Thumb drives
  • When to Use Encryption
      • Any device at risk of theft or exposure
      • Extra-sensitive data
  • Data at Rest
    • Hardware based
      • Built in to the hardware device
      • Advantages
        • Automatically encrypts data
        • Fast
      • Disadvantages
        • Proprietary
        • Lack of central management
  • Data at Rest
    • Software based
      • Advantages
        • Lower cost
        • Does not require specific hardware
      • Disadvantages
        • Need to install, activate and manage it, make sure it’s being used
  • Software Solutions
    • File based (PGP, Winzip)
      • Done on a file-by-file basis (only protects file)
      • Not automatic
      • Dependent on end-user
    • Volume based (TrueCrypt)
      • An encrypted “virtual drive” is created
      • All files written are encrypted automatically
      • Does not necessarily encrypt all files – for example, Windows system files, security files, temp files …
  • Software Solutions
    • Disk based (whole-disk encryption)
      • Encrypts entire drive (most secure)
      • Automatic; transparent to the user
      • But … if you lock yourself out, you’re in trouble
        • Need administrative control
  • Key Management
    • Elephant in the room – the only other requirement set forth by the Department of Defense policy
      • “ Mechanism to recover data if the primary encryption system fails”
      • Need for the organization to keep control of the keys rather than individuals
        • Lost passwords
        • Lost individuals
        • Access control (control of data, investigations)
  • Bad Practices
    • Data encrypted with a single-key system is a security risk to the organization
    • Added note…
      • “ If I accidently leave my computer unlocked and someone gets it, I don’t have to worry because the hard disk is encrypted…”
      • Risk of sleeping
      • Full disk encryption vulnerability
      • Turn systems off
      • Bad practices trump good security
  • ESO Recommendations
    • Develop agency-wide strategy and approach to encryption
    • Centralize key management and recovery processes
    • Do some research and planning
    • When justifying cost, consider cost of data disclosures, lost data and reputation
    • Look for group purchase opportunities

  • Agency Panel
    • Cindy Slye, Oregon Department of Transportation
    • Marty Liddell, Oregon Employment Department
    • John McKean, Oregon Lottery
  • Agency Panel
    • Cindy Slye, Project Manager
    • Oregon Department of Transportation
  • Business Drivers
    • New DAS EIS Policies:
      • Information Security
      • Employee Security
      • Controlling Portable and Removable Storage Devices
      • Transporting Confidential Information
  • Business Drivers
    • Compliance with:
      • Regulated mandates – Federal Motor Carrier Safety Administration (FMCSA)
      • Senate Bill 583
      • ODOT policies and guidelines
  • Project Objective
    • Find the best data encryption product that can protect sensitive data by:
      • Securing information on mobile devices
      • Securing information on removable devices
      • Providing the best comprehensive solution to cover all areas
      • Simplifying deployment, maintenance and data backup
  • How Does It Align With Our Goals? ODOT IT Strategic Plan Senate Bill 583 DAS Policy Controlling Portable and Removable Storage Devices Federal Motor Carrier Safety Administration ODOT Security Fabric Initiative Protect , Manage Protect , Manage Protect , Manage
  • Consequences
    • What are the consequences of compromising sensitive information?
      • Negative publicity
      • Loss of customer confidence
      • Damaged reputation
      • Financial loss
  • Safe Harbor Provision
    • Data encryption is the most effective solution for safeguarding sensitive electronic data
    • Data encryption is identified as an acceptable “Safe Harbor” approach in providing privacy assurances
      • If the information is properly encrypted:
        • No further duty
        • It may be assumed that no privacy breach has occurred
        • Risk mitigation approach that limits agency liability
        • Enhances trust in the event of a security breach
  • Candidates We Considered
  • Why Guardian Edge?
    • Guardian Edge clearly met ODOT business requirements:
      • Strong Active Directory Integration
      • Ease of Use
      • Robust Management Console (MMC)
      • Facilitates Compliance with DAS and ODOT Security Policies
  • Magic Quadrant for Mobile Data Protection
