GRAFENWOEHR, Germany -- Soldiers and family members are facing the growing need to protect themselves from cyberthreats on social media, according to top leadership here.

A Soldier within the U.S. Army Garrison Bavaria footprint recently received messages on a private Facebook page deemed by investigators as malicious and aggressive.

"Potential foreign adversaries are using social media to make threats toward service members," said Adam Troxel, lead special agent with the 66th Military Intelligence Brigade.

The threatening messages on Facebook underscore the need to grow awareness about social media as part of the cyberspace domain -- potentially exploitable by online predators and adversaries.

The U.S. Army Operating Concept -- which presents a vision of how future Army forces will operate in an unknowable and constantly changing environment -- acknowledges that state and non-state actors have used social media to influence perceptions and provide cover for large-scale military operations. The concept also explains that "social media amplifies and accelerates interaction between people, governments, militaries and threats."

But to date, social media remains largely outside the scope of Army doctrine. That leaves the responsibility on social media users -- 83 percent of Americans have a social media account, according to the U.S. Army Social Media Handbook -- to protect themselves within the cyber domain.

Leaders here are now calling on service members, DOD employees and families to take a more strategic and proactive role in social media.

"The future operational environment is not only unknown, but unknowable and constantly changing," said Brig. Gen. Tony Aguto, commander of 7th Army Training Command. "It's time we acknowledge social media as an extension of cyberspace within our complex world."

As social media continues to evolve, so too has the number of online predators. While only a few years ago cybersecurity implied protecting personal information online, today cybersecurity translates into a more proactive role.

"As members of the U.S. military deployed oversees, we need to approach social media in the cyber domain the way we might approach any dangerous and unfamiliar territory: Be smart and keep a low profile," said USAG Bavaria Garrison Commander, Col. Lance Varney.

Soldiers and their families need now more than ever to step up their game in protecting their online identities -- from tightening security settings on Facebook to ensuring name tags are not in view in photographs shared online.

"Question legitimacy of unsolicited online traffic and and don't leave your personal details open to unfamiliar eyes," Aguto said. "Open source intel collection is real, and as U.S. personnel we shouldn't make it easy for adversaries to target, collect or intimidate."

"Together we can increase Army readiness overseas and on the battlefield through social media vigilance," Aguto said. "Soldiers, families and civilians all play a role in our cyber mission force readiness."
