Every day millions of people utilize electronic devices to access the internet. When most people go online they aren't actively thinking about security; they don't pay attention until it's too late.
The 6th Signal Center, also known as the Korea Theater Network Operations and Security Center (K-TNOSC), protects South Korea's LandWarNet. LandWarNet consists of Army and Joint DoD classified and unclassified communications and computing systems, software, data security services, and other associated services. Most users have no clue these shadow warriors are keeping their computers, emails, and their lives safe.
"Operation, maintenance, security and defense of the strategic network in South Korea is our core function," said Lt. Col. Roberto R. Castillo, the 6th Signal Center director. "Our cyber and network operations enable senior leaders to make critical decisions."
Enemies of the United States and individual actors attempt to hack DoD networks every day and the 6th Signal Center does its share to defend against malicious intent.
I get to work independently analyzing data that helps to protect our networks, said Capt. Jeffrey Jao, a 6th Signal Center cyber operations officer. The job that I do allows commanders to communicate on the battlefield without compromise.
To put into perspective, the breadth of the 6th Signal Center mission, the unclassified network that they help to monitor is the largest private network in the world. Though there are less users on the Army's secret and top secret networks, the stakes are higher with national security at risk.
The 6th Signal Center employs highly technical soldiers and civilians who work to keep the networks safe around the clock.
Cyber security is only as good as the people that manage and use it, explained Carl D. Turnbow, a civilian information assurance chief in the 6th Signal Center.
