text: Overview of Signal Support
  1-88. Commanders must recognize the proliferation of threat cyberspace capabilities and their impact on
  operations. Threat activities in cyberspace can disrupt friendly information systems and degrade joint
  command and control. Threat operations in cyberspace are often less encumbered by treaty, law, and policy
  restrictions than those imposed on U.S. forces. This may allow enemies and adversaries an initial advantage
  in cyberspace. Signal support elements and staffs must maintain an effective cybersecurity program to secure
  the network against threat activities in cyberspace.
  INSIDER THREAT
  1-89. Insider threats present a significant risk to military operations. An insider threat is a person with
  placement and access who intentionally causes loss or degradation of resources or capabilities or
  compromises the ability of an organization to accomplish its mission through espionage, providing support
  to international terrorism, or the unauthorized release or disclosure of information about the plans and
  intentions of U.S. military forces (AR 381-12). Insider threats are hostile actors who intentionally
  compromise national security through deliberate actions. Insider threat should not be confused with
  operations security or cybersecurity risks, where sensitive operational information may be accidentally
  compromised and place U.S. operations or personnel at risk.
  1-90. An insider threat does not necessarily need to be a military member or government employee. Third
  party vendors, contractors, and partners could pose a threat as well. The insider threat is especially dangerous
  because insider activity is generally the hardest to identify. Downloading or printing files to remove from
  secure areas may appear to be ordinary day-to-day activities. Similar to enemy cyberspace attacks, a trusted
  insider can steal sensitive data to undermine partner relationships or manipulate public opinion.
  1-91. Past cases of insider threats have demonstrated that coworkers, associates, friends, and supervisors of
  those engaging in espionage or terrorist activity commonly overlook potential threat indicators. If these
  indicators had been reported and investigated, they might have minimized the damage to national security or
  saved the lives of U.S. personnel. The knowledge, awareness, and participation of all Department of the
  Army personnel in threat awareness and reporting is essential to the success of the Army’s warfighting
  mission and in protecting the lives of Soldiers (AR 381-12).
  SECTION II – FUNDAMENTAL PRINCIPLES OF SIGNAL SUPPORT
  1-92. The network connects geographically separated forces for network-enabled operations. Because the
  Army conducts operations as part of a joint force, signal support requires joint interoperability in systems
  engineering, planning, deployment, and operation. Joint forces must be networked, linked, and synchronized
  in time and purpose so dispersed forces can communicate, maneuver, share information, collaborate, and
  share a common operational picture.
  1-93. By integrating information from across the operational area, Army forces can maintain timely and
  relevant situational understanding. The integrated common operational picture allows commanders to
  manage operational risk and employ the right capabilities at the right place and time to achieve mission
  objectives. Making this possible requires signal Soldiers and leaders to apply the fundamental principles of—
  * Operational focus.
  * Interoperability.
  * Agility.
  * Trusted systems.
  * Shared networks.
  * Situational awareness.
  OPERATIONAL FOCUS
  1-94. Communications support should never be the limiting factor to the commander’s ability to execute a
  mission. Signal staffs need to understand the commander’s scheme of maneuver and intent and be able to
  articulate the capabilities and limitations of their communications systems to their commanders. This way,
  commanders can employ their signal capabilities to best support the operation.
