There already are battles inwards cyberspace. The Defense Information Systems Agency (DISA) has got the warriors — in addition to the weapons — to seek out it. And only every bit inwards kinetic war, it takes constant adaptation, novel strategies, tactics in addition to weapons to engage adversaries whose ain agency in addition to methods are constantly changing. DISA’s Acropolis is the infrastructure upon which the agency runs its platforms in addition to tools – the weapons – to rails downward in addition to contend off opponents. “This partition has been working alongside Acropolis since it was invented nearly fifteen years ago,” said DISA’s medico Jim Travis, principal of the Cyber Situational Awareness/Cyber NetOps Solution Division. “It’s lots in addition to lots of servers that nosotros run defensive cyber solution operations on top of…Acropolis is a stack of things, alongside specialists at each layer.” The Big Data Platform (BDP), the layer directly inwards a higher house Acropolis, provides a mutual computing solution that’s able to ingest, store, process, part in addition to visualize multiple petabytes of information drawn from the Department of Defense Information Network (DoDIN), sources such every bit the Joint Regional Security Stacks, Defense Information Systems Network (DISN) Operational Support System, enclaves in addition to endpoints, in addition to gateways – it provides the network of alerts that notify DISA when something is wrong.
“We do, inwards fact, run commercial threat intelligence sources, in addition to nosotros guide keep i vendor that does external scanning of the DoD space, [the kinds of] things adversaries mightiness practise hence nosotros tin dismiss guide keep context for how good we’re preparing. … We can’t hold off until they acquire to our doorstep.”
“I guide keep [ten] unlike platforms for ingesting data,” Travis said. “There are unlike safety classifications, unlike need-to-knows, unlike accreditation boundaries, hence nosotros guide keep unlike domains.” DISA is looking at ways to collapse those into a smaller number; it won’t salve money, he said, since the sum of information inwards storage volition rest the same, “but it allows me to growth the potential surface of what tin dismiss hold upward correlated.”
The tertiary layer is Cyber Situational Awareness Analytic Capability, or CSAAC, the collection of tools – weapons – to response to threats in addition to supply a mutual situational awareness across DoDIN Operations in addition to Defense Cyberspace Operations. “The tools are of express value unless they’ve been develop to hold upward used yesteryear warfighters,” Travis said. Data scientists, visualizers in addition to others alongside specific cyber in addition to programming skills piece of job alongside warfighters to discover the solutions they ask in addition to deploy them.
The agency is looking to expand on Acropolis’ capabilities yesteryear incorporating commercial cloud every bit on an as-needed basis.
“Some of the kinds of queries that ask to hold upward run ask to a greater extent than compute [power] than nosotros tin dismiss guide keep standing to a greater extent than or less idle,” Travis explained, “so we’re redesigning to guide keep wages of cloud providers, [so that] nosotros tin dismiss spin up, hence plough off…My branch principal can’t acquire a yard cores to present upward inwards 10 seconds.”
Another expanse that DISA is evolving toward is the run of a DevOps approach inwards gild to practise tools to a greater extent than quickly, using a novel opened upward rootage environs called Zeppelin.
“My target is iv days from requirement to evolution to production,” he said. “From a pure analytics approach, that’s the way ahead.”
This sounds similar a straightforward operation, until i considers the vast compass of the threats.
“In our let on i application correct now, nosotros guide keep 219,532 [threat] indicators,” he said, “102,732 countermeasures are approved for use. This is from 150 unlike reporting sources, alongside 10,157 active or passive detection signatures, to a greater extent than than a meg attributes.”
With waves of threats of that magnitude, machine learning in addition to artificial intelligence come upward into play.
When a sensor detects a threat indicator, an alarm is sent upstream, where the threat is referenced against countermeasures that already guide keep been approved; if in that place is an approval, the arrangement itself releases the counterattack order. If in that place is no approved countermeasure, the alarm is sent to some other partition for a human to visit what response is appropriate.
“There volition come upward a 24-hour interval when there’s a cyber nation of war alongside machines fighting machines,” Travis said. “We’re doing some [now], but exclusively against known assault sources. If y'all desire to bargain alongside the unknown unknowns, y'all desire to acquire [auto] orchestration. But it’s withal going to hold upward a warfighter conclusion whether to plough it on or not, [and] in i trial it’s turned on, it volition let the warfighter to brand tweaks to let the skillful guys through.”
