While the IC’s research organization looks into adding security to cloud environments, in the here and now, intelligence agencies are sharing more data.
The Internet of Things holds a world of possibility for federal agencies, but in order to leverage that potential, they’ll need a more agile computing platform.
Enter fog computing, which could offer users greater functionality from distributed endpoints and environments.
While cloud computing carries data back to a central server for storage and analysis, fog computing enables analytics and other functions to be performed at a network’s edge, right at the data source. Fog systems provide faster functionality for users, but also come with enhanced security risks that IT managers must weigh before implementing.
Forrester Analyst Andre Kindness says the rise of fog computing may be a response to otherwise insufficient data transfer capacity.
“There’s not enough bandwidth worldwide to move data like we want,” Kindness says. “The reality is the network cannot keep up.”
Unlike cloud computing, fog computing allows smart devices to send, receive and store information within a closer geographic area, making it a natural partner to the IoT.
"There’s pressure to push computing power to the edge, to deliver the most capable analytic power at the most appropriate point,” says Rick Holgate, a research director with Gartner. “Fog computing can deliver better insights closer to where the data gets collected.”
Gary Hall, Cisco Systems’ federal defense chief technology officer, says the Department of Defense already uses fog technologies to connect soldiers and commanders in the field with the intelligence community, speeding decision-making.
The military also deploys fog computing on bases to support lighting, parking and security systems.
“If we install a fog system and LED lighting, we can automatically dim the lights when no one is in a room,” Hall says. “A system like this quickly pays for itself.”
The Transportation Security Administration will soon deploy the technology to gain enhanced data analytics capabilities at local checkpoints.
“They’re able to batch-scan the passenger queue as it’s in motion, looking for anomalies, chemicals and facial recognition of known terrorists,” Hall says. “It’s a great application of fog computing because it increases protection.”
While fog computing streamlines data collection, storage and analysis, it also presents a significant security risk. Extending the network’s edge increases the potential for cyberattacks, Hall says.
“If someone hacks into a phone, that’s inconvenient and embarrassing,” he says, “but if someone hacks into your fog network, that can be dangerous.”
Hall offers the example of a hacker accessing a car’s network. A perpetrator could hack into a connected car and deploy the airbags, causing an accident at highway speeds.
“The ability to unlock fog’s potential value depends on our ability to secure it,” Hall says.
Despite those concerns, Hall predicts significant strides in agencies’ use of fog computing in the coming year.
“Initiatives are maturing and will start to show real results,” he says. “We won’t see an instant transformation, but I believe we’ll see more in 2016.”
