Business challenge story
Think differently about threat intelligence
Today, no company can operate without robust cybersecurity. While companies dedicate resources to responding to possible cyberthreats, their cyberteams are overburdened by spending valuable time researching threats that have passed, rather than concentrating on real-time prevention. Despite their efforts, it remains extremely difficult to collect, process and operationalize threat intelligence on a live network.
“Having massive libraries of information with the only action of producing reports for others to read is useful for strategic decision-makers in understanding threats to their industry but not necessarily the best approach tactically,” says Jess Parnell, Vice President of Security Operations for Centripetal. “Producing intelligence is highly valuable, but not using it actively and in a timely manner in defending the network has historically been a grave mistake.”
As cyberthreats have evolved, so has the field of threat intelligence. Today, more than enough intelligence is available to detect and stop almost any cyberattack. But until recently, there was no effective way to take all that intelligence and automatically apply it to prevent threats in real time.
To counter this problem, Centripetal designed its proprietary RuleGATE threat intelligence gateway to automatically operationalize threat intelligence on a zero-trust basis. Centripetal stops cyberattacks bi-directionally, before they can infiltrate into or exfiltrate data from the network. The company created this filtering engine that can ingest, apply dynamic rules to and act on billions of threat indicators, all in real time. Leveraging all available intelligence and inspecting every single network packet provides the most advanced level of zero-trust security.
Centripetal receives threat intelligence from multiple sources, but its gateway needs a reliable, accurate and frequently updated source of threat intelligence to successfully stop cyberthreats. As the company ramped up and refined its gateway technology to create a service offering to customers, it sought new cyberthreat intelligence sources.
“We don’t actually make threat intelligence,” says Parnell. “We call it gasoline for the engine, our RuleGATE. It needs intelligence to pinpoint malicious activities within the network and to proactively protect it.”
In 2018, Centripetal and a team from IBM Security X-Force connected through a mutual customer. Centripetal tested the IBM Security X-Force Exchange Commercial API software as a service (SaaS) solution and decided that it wanted to use it, but at a rate far higher than any other client. Many times, IBM Security X-Force clients subscribed to the service in one or multiple packs of 10,000 records per month. In this case, Centripetal wanted to consume records immediately upon availability, which amounted to 17 million records monthly. The IBM team was able to offer a solution to meet Centripetal’s needs.
Operationalize intelligence to reduce risk
Centripetal offers its CleanINTERNET service to customers who want to protect their networks proactively rather than reactively. The company uses the IBM Security X-Force Exchange Commercial API feed from IBM as one of its key sources of threat intelligence, making it actionable through its service. All of this happens with no discernable network traffic delay, and with no firewall or other security stack device involvement, thanks to the RuleGATE gateway. Centripetal can customize its end user customers’ consumption of threat intelligence insights with its CleanINTERNET service, which accesses the cloud-based IBM Security X-Force Exchange platform through a RESTful API.
“We pull down the X-Force data in real time,” says Dave Ahn, Chief Architect and Vice President at Centripetal. “All the data — not just a subset, but all of it. We’re unique in this area in that most solutions can’t consume anywhere near that quantity of intelligence and make it actionable.” In fact, the Centripetal solution consumes billions of threat indicators daily from multiple threat intelligence sources, including the IBM Security X-Force solution.
Centripetal pulls the IBM Security X-Force threat intelligence, including IBM analyst-designated threat indicators, into its analytics platform, where the clearly “all-risk” threats are designated for immediate shielding by the RuleGATE threat intelligence gateway. The CleanINTERNET service shields these events proactively to enable a granular, detailed secondary inspection triage to occur in real time.
After the shielding event load reduction, Centripetal then uses these secondary inspection technologies to analyze all other threat events proactively along a risk gradient. A second category of “monitor-worthy” traffic emerges at this point which may be decrypted, payload analyzed and captured. Finally, some traffic is immediately scored as “low-confidence” or “informative,” and no action is taken. The categorization varies by customer based on their risk profile and evolves over time as new threats emerge. As Ahn notes, “Our analytic platform and our analysts are engaged with the intelligence and with the customer to map the intelligence to what is actionable for each and every customer.”
The Centripetal team has high confidence in the IBM Security X-Force threat intelligence indicators. “Our analysts … feel very confident in IBM X-Force indicator set and many are readily shield-worthy,” says Parnell. “IBM’s scoring and the way that X-Force provides the intelligence are both very reliable. That’s not always the case for all of the different variety of intelligence that we're getting.”
The Centripetal CleanINTERNET service is also dynamic, automatically upgrading the monitor-worthy intelligence to shield-worthy as IBM threat indicators change. “The big gray area in the middle is really a lot of the value that you’re providing us,” says Parnell. “And the reason why it’s so valuable to us is that we do a secondary inspection of the data.”
In that secondary inspection, the Centripetal RuleGATE uses monitor-worthy intelligence indicators to pivot and pass potentially malicious traffic through deep packet analysis engines, such as content-based intrusion detection systems and signature-less inspection technologies where they may “fire” on a subset of targets, such as command and control infrastructure. This analysis enriches Centripetal’s real-time decision-making and proactive response to the threats. The company’s approach uses the original intelligence indicators to add valuable context about the traffic. “That makes the indicator truly actionable,” says Parnell. “The end result is a greater degree of Shielding where we can offload risk.”
Automate threat protection to save time, money
By operationalizing threat intelligence pulled from the IBM Security X-Force Exchange Commercial API solution, Centripetal provides its customers with a cyberthreat defense solution that actively shields the highest-risk traffic in real time. Centripetal chose the IBM solution for its high quality and because it is designed for reliability. The IBM Security X-Force Exchange Commercial API is not a one-size-fits-all intelligence feed. Centripetal leverages the raw data dynamically in its inspection architecture based on its individual customers’ needs.
“IBM provides very good indicators of compromise in a very timely fashion,” says Parnell. “We bring in those indicators, and within minutes those indicators are protecting our clients across the board.” The high-confidence indicator sets, coupled with a low rate of false-positives, have made the IBM Security X-Force solution valuable for Centripetal.
The company’s CleanINTERNET service automates threat protection and shields against threats with negligible impact on network performance thanks to the performance of each of Centripetal’s patented inspection technologies. This is the crux of the difference between traditional, manual security postures, and the CleanINTERNET service, according to Parnell. “It’s really cool to show traditional security stack people how this all happens without any user intervention,” he says. “We’re using machine to machine, we’re using high-quality data, we’re dynamically responding to billions of threats, and all of that has no negative IT impact. But it does effectively shield you from attack.”
The combination of automation and the high-quality threat intelligence from IBM Security X-Force creates other, indirect benefits for customers. For example, when Centripetal used the IBM Security X-Force and other threat intelligence data to shield against malicious activity at a large hospital system in the Northeast, the group saw a 70% reduction in attacks that needed to be investigated and resolved, which helped improve analyst efficiency and reduce costs. This allowed their team to concentrate on mission-critical risks to dramatically increase their cybersecurity posture. And, Centripetal reports the IBM Security X-Force service falls consistently within the top tier of solutions that reduce attacks by the greatest percentage.
According to Ahn, the IBM Security X-Force solution and the Centripetal CleanINTERNET service are a winning combination. “It’s the reliability and the consistency of the IBM threat research, input into our approach for applied intelligence, that leads to proactive protection,” he says. “And the IBM research carries a lot more weight than some intelligence developed ad hoc.”
Centripetal’s customers benefit from the highly reliable intelligence from the IBM Security X-Force Exchange through Centripetal’s use of the IBM Security X-Force Exchange Commercial API service. “With the Centripetal solution, our customers are benefiting from the IBM analysts’ opinions in real time for their own threat protection,” says Parnell. “And that is extremely powerful.”
Subscribing to the IBM Security X-Force Exchange Commercial API solution gives Centripetal access to the wider collection of intelligence available through the IBM Security X-Force Exchange platform portal. This includes information on specific security investigations, or collections, consisting of both unstructured and structured data, incident descriptions and associated observables relevant to the incident, and comprehensive intelligence on emerging threat indicators and the context to understand them. “We can go to the portal and get enough information so we can make quick decisions about what to tell our clients and also potentially how to remediate the threat,” says Parnell.
IBM Security X-Force and Centripetal are looking to the future of working together to improve threat intelligence. Already, thanks to its experience with Centripetal, IBM has created an Enterprise API version of the IBM Security X-Force Exchange intelligence feed designed for the kind of massive threads that Centripetal consumes. “We now have a number of years of history [with IBM Security X-Force], and we think that there can be a lot more collaboration,” concludes Parnell. “We are very excited about that and to explore those future steps.”
