Agenda

• Data protection and archiving

• Data encryption

• Key management

• Oracle key management solution

Data Protection and Archiving

• Online storageBackupArchive

• Data retention time

• Sometimes data needs to be deleted immediately after data retention time

Data Encryption

Confidential – Oracle Internal/Restricted/Highly Restricted

Encryption

• Data encryption transforms plaintext into ciphertext

• Satisfy Customer or regulatory requirements

• Protection from both off-site and on-premise information loss

• Secure shipment of data

• Time-based data expiration

• Secure data disposal

It’s All About the Keys

• Encryption keys determine the functional output of an encryption algorithm

• Keys must be ‘strong’

– Randomly and securely generated

– Securely managed

– The longer the key length, the more secure the encryption method

• Advanced Encryption Standard (Rjindael)AES 256 is most secure encryption standard available today

– Symmetric, block cipher-based method

– 256 bit key length

– Substitution, permutation, XOR

– 14 round different keys (AES 256)

Lose the keys and you lose the data!

Best Practices for Key Management System

Keep Your Data Secure

Always Available•Redundant Servers•Backup/Recovery

Secure•Key Storage•Access Control

Scalable•Simple setup•Easy to use

Openly Architected•Standard protocols•Multiple end-points

Traceable•Auditing/reporting tools•Alerts

Oracle Key Manager 3

• Simple to Install and Operate

– Automated, policy-driven system

– Server, O/S, application neutral

• Secure

– Strongest encryption (AES-256) end-to-end

– Strong key protection mechanisms

– Conforms to federal security certifications (FIPS)

• Scalable

– Supports large sites & multiple storage technologies

– Easily adds more key management appliances, sites and drives

OKM is a cluster of servers (OKMs) managing keys for encrypting devices

OKM Architecture

Scalability

• Scales economically– Supports multiple sites/devices concurrently

– Tested with up to 2,000 drives and 1,000,000 keys

• Transparent/non-disruptive growth

– Add more OKM appliances, sites and drives as needed

• Flexible management

– Supports managing multi-site installation from any single location

– Supports multiple user roles

Oracle Key Manager 3 Components• Key management appliance (OKM)

– Solaris on SPARC T7-1 server

– Oracle key management software

– Hardware Security Module (optional)

• OKM cluster

– 2 to 20 OKMs, connected via Ethernet network

• OKM management server

– OKM management GUI

• Encryption end-points

– Tape drives

– ZFS

– Oracle Database

– Java applications

SPARC T7-1

Key Management Appliance

• Security-enhanced SPARC T7-1 server with a hardened solution

• Appliance device:

– Simple installation and automatic operation

– No OS/driver administration or maintenance is required

– Scales easily and transparently

• Runs independently of backup server, operating system, applications, and device drivers

• Cluster 2 to 20 OKMs together for high availability enterprise wide key management system

OKM 3 Encryption End Points

• Tape Drives– T10K A, B, C, D & T9840D

– LTO 4, 5, 6, 7

• Java Applications

– JCE Provider

• Oracle Database

– Transparent Database Encryption

• ZFS Storage– PKCS#11 Provider

– (The PKCS #11 standard defines a platform-independent API to cryptographic tokens)

Separate Key and Data Paths

• Key communication over dedicated Ethernet port

• Drive compresses data before encrypting

• Non-disruptive

– Coexist with non-encrypting devices

– No changes/awareness required in storage server and data network

Storage server

Performance

• Data transfer rates are not affected by encryption– Encryption handled by the device

– No storage server CPU cycles used

• Dedicated key network

– No network contention

• Any OKM server can supply keys to any drive (in the same service network)

• Low key communication latency

– Typically less than 250ms

• Key pre-generation, caching & pre-fetch

Role Based Access Control (RBAC)

• Implementing a role-based access control model

• Users may be assigned one or more roles

• System operations assigned to roles

• Support for built-in (canned) roles

– Security Officer

– Compliance Officer

– Operator

– Backup Operator

– Auditor

– Quorum Member

Keys, KeyIDs and DataUnitID

• Each piece of media is identified by unique DataUnitID– Automatically generated at initial mount point

– Oracle Key Manager associates Volser with DataUnitID in internal database

– Allows user to select keys based on Volser for export/sharing

• Delivers policy-based access control on per tape basis

• Unique Key ID and Keys is supplied to drive from OKM as required

• KeyID is written to media along with each data block

• No encryption keys are stored on tape!

– OKM stores DataUnitID & KeyID/Key pairs in internal database

Key Groups

• Keys are organized into key groups

• Each key group has a key retention policy assigned

• Drives are assigned to key groups

• Drives can only access key groups they are assigned to: – Drive A cannot access keys in Group 2

– Drive B can access keys in Groups 1&2

• Drive needs to have default key group to be able to create new keys

– Both drives create new keys in Group 1

Mirroring

• Key, policy and administration changes made in single OKM are automatically propagated to all parts of the cluster

• Key database is replicated across entire cluster

– Robust fault tolerance

• Any OKM can supply keys to any device in its cluster

Auditing and reporting

• GUI as a primary user interface to manage– Audit Events

– OKMs

– SNMP Managers

– Agents

– Logs

– Users, Key groups and policies

• User can download info from list panels (View → Save Report)

Security

• Role & access control

• Hardened solution

– No other applications, patches/upgrades and/or administration settings to compromise security

• Dedicated key management and key transport (service) networks

• Conforms to stringent federal security certifications (FIPS 140-2 level 3)

• Strong key protection mechanisms– Strong encryption (AES-256) end-to-end

Hardened key management appliance

• Security hardened appliance – Hardened SPARC T7-1 server

– Hardened Solaris 11 OS

– FIPS compliant key generation with optional SCA 6000 card

• OKM hardware and software is engineered to work together.
