We Need the Security Benefits of AI and Machine Learning Now More Than Ever

Reading Time: ~ 3 min.

As these times stress the bottom lines of businesses and SMBs alike, many are looking to cut costs wherever possible. The problem for business owners and MSPs is that cybercriminals are not reducing their budgets apace. On the contrary, the rise in COVID-related scams has been noticeable.

It’s simply no time to cut corners in terms of cybersecurity. But there is hope. Cybersecurity, traditionally suffering from a lack of qualified and experienced professionals, can be a source of savings for businesses. How? Through the automation and efficiency that artificial intelligence (AI) and machine learning can offer.

AI & ML in Today’s Cybersecurity Landscape

By way of background, Webroot has been collecting IT decision makers’ opinions on the utility of AI and machine learning for years now. Results have been…interesting. We’ve seen a steady rise in adoption not necessarily accompanied by an increase in understanding.

For instance, during a 2017 survey of IT decision makers in the United States and Japan, we discovered that approximately 74 percent of businesses were already using some form of AI or ML to protect their organizations from cyber threats. In 2018, 74 percent planned even further investments.

And by 2019, of 800 IT professional cybersecurity decisionmakers across the globe, a whopping 96 percent reported using AI/ML tools in their cybersecurity programs. But, astonishingly, nearly seven out of ten (68%) of them agreed that, although their tools claim to use AI/ML, they aren’t sure what that means.

Read the full report: “Do AI and Machine Learning Make a Difference in Cybersecurity?”

So, are these tools really essential to securing the cyber resilience of small businesses? Or are they unnecessary luxuries in an age of tightening budgets?

AI and ML in the Age of Covid-19

Do AI and ML have something unique to offer businesses—SMBs and MSPs alike—in this age of global pandemic and remote workforces?

We asked the topically relevant question to it to one of the most qualified individuals on the planet to answer it: literal rocket scientist, BrightCloud founder, and architect behind the AI/ML engine known as the Webroot Platform, Hal Lonas.

Can AI and machine learning tools help people do their jobs more effectively now that they’re so often remote?

Put directly, the Carbonite and Webroot CTO and senior VP’s response was bullish.

“AI and machine learning tools can absolutely help people do their jobs more effectively now more than ever,” said Lonas. “Security professionals are always in short supply, and now possibly unavailable or distracted with other pressing concerns. Businesses are facing unprecedented demands on their networks and people, so any automation is welcome and beneficial.”

In machine learning, a subset of AI, algorithms self-learn and improve their findings and results without being explicitly programmed to do so. This means a business deploying AI/ML is improving its threat-fighting capabilities without allocating additional resources to the task– something that should excite cash-strapped businesses navigating tough economic realities.

Our AI/ML report backs up Lonas’s assertion that these technologies make a welcome addition to most business security stacks. In fact, 94 percent of respondents in our survey reported believing that AI/ML tools make them feel more comfortable in their role.

“People who use good AI/ML tools should feel more comfortable in their role and job,” he asserts. “Automation takes care of the easy problems, giving them time to think strategically and look out for problems that only humans can solve. In fact, well-implemented tools allow security workers to train them to become smarter—in effect providing the ‘learning’ part of machine learning. Each new thing the machine learns makes more capable.”

AI/ML adopters also reported:

  • An increase in automated tasks (39%)
  • An increase in effectiveness at their job/role (38%)
  • A decrease in human error (37%).
  • Strongly agreeing that the use of AI/ML makes them feel more confident in performing their roles as cybersecurity professionals. (50%)

So despite some confusion about the role these technologies play in cybersecurity (which we think vendors could help demystify for their clients), their effects are clearly felt. And because cybercriminals are willing to adopt AI/ML for advanced attacks, they may force the hands of SMBs and MSPs if they want to keep up in the cybersecurity arms race.

Given today’s limited budgets, dispersed workforces, and increasingly sophisticated attacks, the time may never be better to empower professionals to do more with less by automating defenses and freeing them to think about big-picture cybersecurity.

AI and ML in Cybersecurity: Adoption is Rising, but Confusion Remains

Reading Time: ~ 3 min.

If you’ve been working in the technology space for any length of time, you’ve undoubtedly heard about the rising importance of artificial intelligence (AI) and machine learning (ML). But what can these tools really do for you? More specifically, what kinds of benefits do they offer for cybersecurity and business operations?

If you’re not so sure, you’re not alone. As it turns out, although 96% of global IT decision-makers have adopted AI/ML-based cybersecurity tools, nearly 7 in 10 admit they’re not sure what these technologies do.

We surveyed 800 global IT decision-makers across the U.S., U.K., Japan, and Australia/New Zealand about their thoughts on AI and ML in cybersecurity. The report highlighted a number of interesting (and contradictory) findings, all of which indicated a general confusion about these tools and whether or not they make a difference for the businesses who use them. Additionally, nearly 3 out of 4 respondents (74%) agreed that, as long as their protection keeps them safe from cybercriminals, they really don’t care if it uses AI/ML.

Here’s a recap of key findings based on responses from all 4 regions.

  • 91% say they understand and research their security tools, and specifically look for ones that use AI/ML.
  • Yet 68% say that, although their tools claim to use AI/ML, they aren’t sure what that means.
  • 84% think their business has all it needs to successfully stop AI/ML-based cyberattacks.
  • But 86% believe they could be doing more to prevent cyberattacks.
  • 72% say it is very important that cybersecurity advertising mention the use of AI/ML.
  • However, 70% of respondents believe cybersecurity vendors’ marketing is intentionally deceptive about their AI/ML-based services.

AI and ML matter because automation matters

As we’ve all had to adjust to “the new normal”, IT professionals have had to tackle a variety of challenges. Not only have they had to figure out how to support a massive shift to working from home, but they also have to deal with the onslaught of opportunistic online scams and other cyberattacks that have surged amidst the chaos around COVID-19.

With all of us working to adapt to these new working conditions, it’s become clear tools that enable automation and productivity are pretty important. That’s where I want to highlight AI and ML. In addition to how AI/ML-based cybersecurity can drastically accelerate threat detection—and even predict shifts and emerging threat sources—these technologies can also make your workforce more efficient, more effective, and more confident.

While many of our survey respondents weren’t sure if AI/ML benefits their cybersecurity strategy, a solid percentage saw notable improvements in workforce efficiency after implementing these tools. Let’s go over those numbers.

  • 42% reported an increase in worker productivity
  • 39% saw increases in automated tasks
  • 39% felt they had more time for training, learning new skills, and other tasks
  • 38% felt more effective in their jobs
  • 37% reported a decrease in human error

As you can see, the benefits of AI and ML aren’t just hype, and they extend well beyond the cybersecurity gains. Real numbers around productivity, automation, time savings, and efficacy are pretty compelling at the best of times, let alone when we’re dealing with sudden and drastic shifts to the ways we conduct business. That’s why I can’t stress the importance of these technologies enough—not only in your security strategy, but across your entire toolset.

Where to learn more

Ultimately, AI and ML-based tools can help businesses of all sizes become more resilient against cyberattacks—not to mention increase automation and operational efficiencies—but it’s important to understand them better to fully reap the benefits they offer.

While there’s clearly still a lot of confusion about what these tools do, I think we’re going to see a continuation of the upward trend in AI/ML adoption. That’s why it’s important that IT decision-makers have the resources to educate themselves about the best ways to implement these tools, and also look to vendors who have the historical knowledge and expertise in the space to guide them.

“Realistically, we can’t expect to stop sophisticated attacks if more than half of IT decision makers don’t understand AI/ML-based cybersecurity tools. We need to do better. That means more training and more emphasis not only on our tools and their capabilities, but also on our teams’ ability to use them to their best advantage.”

Thoughtful Design in the Age of Cybersecurity AI

Reading Time: ~ 3 min.

AI and machine learning offer tremendous promise for humanity in terms of helping us make sense of Big Data. But, while the processing power of these tools is integral for understanding trends and predicting threats, it’s not sufficient on its own.

Thoughtful design of threat intelligence—design that accounts for the ultimate needs of its consumers—is essential too. There are three areas where thoughtful design of AI for cybersecurity increases overall utility for its end users.

Designing where your data comes from

To set the process of machine learning in motion, data scientists rely on robust data sets they can use to train models that deduce patterns. If your data is siloed, it relies on a single community of endpoints or is made up only of data gathered from sensors like honeypots and crawlers. There are bound to be gaps in the resultant threat intelligence.

A diverse set of real-world endpoints is essential to achieve actionable threat intelligence. For one thing, machine learning models can be prone to picking up biases if exposed to either too much of a particular threat or too narrow of a user base. That may make the model adept at discovering one type of threat, but not so great at noticing others. Well-rounded, globally-sourced data provides the most accurate picture of threat trends.

Another significant reason real-world endpoints are essential is that some malware excels at evading traditional crawling mechanisms. This is especially common for phishing sites targeting specific geos or user environments, as well as for malware executables. Phishing sites can hide their malicious content from crawlers, and malware can appear benign or sit on a user’s endpoint for extended periods of time without taking an action.

Designing how to illustrate data’s context

Historical trends help to gauge future measurements, so designing threat intelligence that accounts for context is essential. Take a major website like www.google.com for example. Historical threat intelligence signals it’s been benign for years, leading to the conclusion that its owners have put solid security practices in place and are committed to not letting it become a vector for bad actors. On the other hand, if we look at a domain that was only very recently registered or has a long history of presenting a threat, there’s a greater chance it will behave negatively in the future. 

Illustrating this type of information in a useful way can take the form of a reputation score. Since predictions about a data object’s future actions—whether it be a URL, file, or mobile app—are based on probability, reputation scores can help determine the probability that an object may become a future threat, helping organizations determine the level of risk they are comfortable with and set their policies accordingly.

Designing how you classify and apply the data

Finally, how a threat intelligence provider classifies data and the options they offer partners and users in terms of how to apply it can greatly increase its utility. Protecting networks, homes, and devices from internet threats is one thing, and certainly desirable for any threat intelligence feed, but that’s far from all it can do.

Technology vendors designing a parental control product, for instance, need threat intelligence capable of classifying content based on its appropriateness for children. And any parent knows malware isn’t the only thing children should be shielded from. Categories like adult content, gambling sites, or hubs for pirating legitimate media may also be worthy of avoiding. This flexibility extends to the workplace, too, where peer-to-peer streaming and social media sites can affect worker productivity and slow network speeds, not to mention introduce regulatory compliance concerns. Being able to classify internet object with such scalpel-like precision makes thoughtfully designed threat intelligence that is much more useful for the partners leveraging it.

Finally, the speed at which new threat intelligence findings are applied to all endpoints on a device is critical. It’s well-known that static threat lists can’t keep up with the pace of today’s malware, but updating those lists on a daily basis isn’t cutting it anymore either. The time from initial detection to global protection must be a matter of minutes.

This brings us back to where we started: the need for a robust, geographically diverse data set from which to draw our threat intelligence. For more information on how the Webroot Platform draws its data to protect customers and vendor partners around the globe, visit our threat intelligence page.

Context Matters: Turning Data into Threat Intelligence

Reading Time: ~ 3 min.

1949, 1971, 1979, 1981, 1983 and 1991.

Yes, these are numbers. You more than likely even recognize them as years. However, without context you wouldn’t immediately recognize them as years in which Sicily’s Mount Etna experienced major eruptions.

Data matters, but only if it’s paired with enough context to create meaning.

While today’s conversations about threat intelligence tend to throw a ton of impressive numbers and fancy stats out there, if the discussion isn’t informed by context, numbers become noise. Context is how Webroot takes the wealth of information it gathers—data from more than 67 million sources including crawlers, honeypots, as well as partner and customer endpoints—and turns it into actionable, contextual threat intelligence.

What defines contextual threat intelligence?

When determining a definition of contextual threat intelligence, it can be helpful to focus on what it is not. It’s not a simple list of threats that’s refreshed periodically. A list of known phishing sites may be updated daily or weekly, but given that we know the average lifespan of an in-use phishing site to be mere hours, there’s no guarantee such lists are up to date.

“Some threat intelligence providers pursue the low-hanging fruit of threat intelligence—the cheap and easy kind,” says Webroot Sr. Product Marketing Manager Holly Spiers. “They provide a list of of IP addresses that have been deemed threats, but there’s no context as to why or when they were deemed a threat. You’re not getting the full story.”

Contextual threat intelligence is that full story. It provides not only a constantly updated feed of known threats, but also historical data and relationships between data objects for a fuller picture of the history of a threat based on the “internet neighborhood” in which it’s active.

Unfortunately, historical relationships are another aspect often missing from low-hanging threat intelligence sources. Since threat actors are constantly trying to evade detection, they may use a malicious URL for a period before letting it go dormant while its reputation cools down. But because it takes more effort to start from scratch, it’s likely the actor will return to it before too long.

“Our Threat Investigator tool, a visualization demo that illustrates the relationship between data objects, is able to show how an IP address’s status can change over a period of time, says Spiers. “Within six months, it may show signs of being a threat, and then go benign.”

What are the elements of context?

Over the course of a year, millions of internet objects change state from benign to malicious and back numerous times as cyber criminals attempt to avoid detection. And because threats are often interconnected, being able to map their relationships allows us to better predict whether a benign object has the potential to turn malicious. It also helps us protect users from never-before-seen threats and even predict where future attacks may come from.

That’s where the power in prediction lies—in having contextual and historical data instead of looking at a static point in time.

Some elements that are needed to provide a deeper understanding of an interwoven landscape include:

  • Real-time data from real-world sources, supplemented by active web crawlers and passive sensor networks of honeypots designed to attract threats, provide the necessary data for training machine learning models to spot threats
  • An ability to analyze relationships connecting data objects allows threat intelligence providers to make a connections as to how a benign IP address, for example, may be only one step away from a malicious URL and to predict with high confidence whether the IP address will turn malicious in the future.
  • Both live and historical data helps in the development of a trusted reputation score based on behavior over time and common reputational influencers such as age, popularity, and past infections.

Seeing the signal through the noise

Context is the way to turn terabytes of data into something meaningful that prompts action. Having the power to be able to dig into the relationships of internet objects provides the context that matters to technology vendors. For consumers of contextual threat intelligence, it means fewer false positives and the ability to prioritize real threats.

“Working with real-world vendors is key,” according to Spiers. “The reach of contextual threat intelligence and number of individuals it touches can grow exponentially.”

What Defines a Machine Learning-Based Threat Intelligence Platform?

Reading Time: ~ 4 min.

As technology continues to evolve, several trends are staying consistent. First, the volume of data is growing exponentially. Second, human analysts can’t hope to keep up—there just aren’t enough of them and they can’t work fast enough. Third, adversarial attacks that target data are also on the rise.

Given these trends, it’s not surprising that an increasing number of tech companies are building or implementing tools that promise automation and tout machine learning and/or artificial intelligence, particularly in the realm of cybersecurity. In this day and age, stopping threats effectively is nearly impossible without some next-generation method of harnessing processing power to bear the burden of analysis. That’s where the concept of a cybersecurity platform built on threat intelligence comes in.

What is a platform?

When you bring together a number of elements in a way that makes the whole greater or more powerful than the sum of its parts, you have the beginnings of a platform. Think of it as an architectural basis for building something greater on top. If built properly, a good platform can support new elements that were never part of the original plan.

With so many layers continually building on top of and alongside one another, you can imagine that a platform needs to be incredibly solid and strong. It has to be able to sustain and reinforce itself so it can support each new piece that is built onto or out of it. Let’s go over some of the traits that a well-architected threat intelligence platform needs

Scale and scalability

A strong platform needs to be able to scale to meet demand for future growth of users, products, functionality. Its size and processing power need to be proportional to the usage needs. If a platform starts out too big too soon, then it’s too expensive to maintain. But if it’s not big enough, then it won’t be able to handle the burden its users impose. That, in turn, will affect the speed, performance, service availability, and overall user experience relating to the platform.

You also need to consider that usage fluctuates, not just over the years, but over different times of day. The platform needs to be robust enough to load balance accordingly, as users come online, go offline, increase and decrease demand, etc.

Modularity can’t be forgotten, either. When you encounter a new type of threat, or just want to add new functionality, you need to be able to plug that new capability into the platform without disrupting existing services. You don’t want to have to worry about rebuilding the whole thing each time you want to add or change a feature. The platform has to be structured in such a way that it will be able to support functionality you haven’t even thought of yet.

Sensing and connection

A threat intelligence platform is really only as good as its data sources. To accurately detect and even predict new security threats, a platform should be able to take data from a variety of sensors and products, then process it through machine learning analysis and threat intelligence engines.

Some of the more traditional sensors are passive, or “honeypots” (i.e. devices that appear to look open to attack, which collect and return threat telemetry when compromised.) Unfortunately, attack methods are now so sophisticated that some can detect the difference between a honeypot and a real-world endpoint, and can adjust their behavior accordingly so as not to expose their methods to threat researchers. For accurate, actionable threat intelligence, the platform needs to gather real-world data from real-world endpoints in the wild.

One of the ways we, in particular, ensure the quality of the data in the Webroot® Platform, is by using each deployment of a Webroot product or service—across our home user, business, and security and network vendor bases—to feed threat telemetry back into the platform for analysis. That means each time a Webroot application is installed on some type of endpoint, or a threat intelligence partner integrates one of our services into a network or security solution, our platform gets stronger and smarter.

Context and analysis

One of the most important features a threat intelligence platform needs is largely invisible to end users: contextual analysis. A strong platform should have the capacity to analyze the relationships between numerous types of internet objects, such as files, apps, URLs, IPs, etc., and determine the level of risk they pose.

It’s no longer enough to determine if a given file is malicious or not. A sort of binary good/bad determination really only gives us a linear view. For example, if a bad file came from an otherwise benign domain that was hijacked temporarily, should we now consider that domain bad? What about all the URLs associated with it, and all the files they host?

For a more accurate picture, we need nuance. We must consider where the bad file came from, which websites or domains it’s associated with and for how long, which other files or applications it might be connected to, etc. It’s these connections that give us a three-dimensional picture of the threat landscape, and that’s what begins to enable predictive protection.

The Bottom Line

When faced with today’s cyberattacks, consumers and organizations alike need cybersecurity solutions that leverage accurate threat telemetry and real-time data from real endpoints and sensors. They need threat intelligence that is continually re-analyzed for the greatest accuracy, by machine learning models that are trained and retrained, which can process data millions of times faster than human analysts, and with the scalability to handle new threats as they emerge. The only way to achieve that is with a comprehensive, integrated machine-learning based platform.
