  information. All Army military, civilian, and contractor employees whose duties require collecting, using, or
  storing personally identifiable information are responsible to—
  * Be able to recognize and safeguard personal information.
  * Collect personal information only when authorized and needed to perform their duties.
  * Collect only the information necessary.
  * Tell the individual the reason for collecting their personal information, who may see it, and what
  happens if the individual does not provide the requested information.
  * Keep the information accurate, relevant, timely, and complete.
  * Protect the information with encrypted storage.
  * Transmit the information only with encryption and digital signature.
  * Keep personally identifiable information confidential and protect it from misuse, loss, or data
  breach.
  JOINT INFORMATION ENVIRONMENT
  2-243. The joint information environment is a secure environment to share information technology
  infrastructure, enterprise services, and a single security architecture across the DODIN. The joint information
  environment implements enforceable standards and specifications, and common tactics, techniques, and
  procedures among the Services.
  2-244. Security and interoperability of networked computers are configuration-dependent. A single
  incorrect setting on a workstation, router, or switch may leave it vulnerable to a cyberspace attack or unable
  to connect with the DODIN. Security affects every aspect of military operations. Likewise, interoperability
  is vital to mission success. Connecting to the DODIN facilitates collaboration with joint mission partners.
  2-245. Each Service, installation, and organization has traditionally maintained separate security
  infrastructure and processes. This creates too many opportunities for failure and hinders information sharing
  among joint mission partners. Standardized, centralized security allows administrators to apply patches and
  improvements faster and with greater certainty.
  2-246. The joint information environment improves operational effectiveness, standardizes training and
  equipment requirements across combatant commands and geographic regions, enhances security, and allows
  Services and agencies to allocate and align their information technology resources to their mission
  requirements. The joint information environment—
  * Consolidates data centers.
  * Standardizes and converges services, such as identity and access management and e-mail.
  * Reduces the cyberspace attack surface.
  * Provides DODIN-wide situational awareness.
  Global Enterprise Operations Center
  2-247. The Global Enterprise Operations Center is the Defense Information Systems Agency’s top-level
  DODIN operations facility. The global enterprise operations center has complete visibility of the DODIN
  and oversees global DODIN operations to support combatant commanders. The global enterprise operations
  center—
  * Directs global DODIN operations and defensive cyberspace operations-internal defensive
  measures.
  * Prioritizes global cyberspace missions.
  * Acts as the global focal point for integrating unified action partners into mission partner
  environment.
  * Maintains global, joint situational awareness.
