Zero Trust Security

Implementing Zero Trust Controls with Risk Based Context

The concept of Zero Trust Security, originally devised by analyst firm Forrester, centers on the principle that organizations should not trust anything either inside or outside the network perimeter. Instead, the Zero Trust Security model emphasizes that every device and every person attempting to connect to an organization’s systems must be verified before gaining access.

Zero trust upends the old “castle-and-moat” approach to IT security that focused on defending the perimeter against known attacks, while presuming anyone already on the inside was safe. This strategy proved to be faulty. Insider threat incidents continue to spike.

According to the 2019 Verizon Data Breach Investigations Report, more than one third of data breaches now involve internal actors. Meanwhile, Cybersecurity Insiders’ 2020 Insider Threat Report revealed that 68% of organizations confirm insider attacks are becoming more frequent.

“Base the design of your Zero Trust extended network on the way your transactions flow through your business ecosystem and how employees, customers, and applications access data. Use this information to isolate and protect your extended network, enforce access control and inspection policies, and continuously monitor your ZT ecosystem for signs of a breach or other malicious activity.”

Zero Trust In A Borderless IT World

Complicating the situation is that more and more companies no longer have corporate data centers consisting of a contained network of systems. The new trend is toward keeping some applications on-premises and putting others in the cloud. And most users now access applications through a range of devices from multiple locations.

Except for unique situations, the purely on-premises environment is becoming a footnote in IT history – as are the cybersecurity models that once protected such environments.

The Gurucul Zero Trust Approach

At Gurucul, we’ve embraced the Zero Trust Security concept since our founding in 2010. We believe in detecting and stopping malicious behavior from wherever it occurs, whether it’s by external attackers or malicious insiders. Our Gurucul Risk Analytics (GRA) security platform leverages big data and more than 2000+ custom machine learning models to predict, detect and prevent insider threats, access abuse, account compromise and cyber fraud.

In a Zero Trust environment you need to monitor your entire IT environment for signs of malicious activity. You likely have a SIEM tool, along with IAM, IGA, PAM, DLP and probably many more data sources. But these various systems often operate in silos. They provide different types of security data that can sometimes even conflict with one another. GRA aggregates data from all those sources to give you a 360-degree view of your users’ and entities’ behaviors.

GRA collects context from disparate sources in a big data lake. This context can be structured or unstructured and usually includes identity information, access entitlements, user and machine activities, transactions and is combined with asset information, risk and threat context. All of this security soup gets linked together using link analysis algorithms so that GRA can understand who or what is on the network, what they have access to, and what they are doing with that access.

Security Analytics Makes Zero Trust Possible

Guest speaker Chase Cunningham of Forrester joined Gurucul for this data driven webinar to present best practices, illustrated with real-world use cases, on how security analytics can be used to automate policy enforcement and controls to implement a Zero Trust architecture.

With GRA there is no reliance on rudimentary rules-based controls favored by conventional security tools. SIEM, DLP and other rules-based security products can only detect known threats. They’re of little use against new types of malware, zero-day attacks and insider threats. GRA provides full coverage for both known and unknown threats, a critical component of a Zero Trust model.

With digital transformation initiatives that are transforming IT environments, Zero Trust requires a security solution that can operate in your unique IT ecosystem. Whether you have a cloud, on premises, or hybrid infrastructure, Gurucul has a deployment option for you including appliances, virtual machine images, cloud-based, bare-metal and as a managed security service. So, even as you migrate to a hybrid or cloud infrastructure, GRA can seamlessly transition with you.

For an effective Zero Trust environment, you must also embrace automated security operations that can proactively find and neutralize cyber threats. Even now, many organizations still use manual processes to reactively intervene when security threats pop up, slowing the response time to cyberattacks. This labor intensive approach gives attackers more time to steal data and inflict damage.

Your cybersecurity staff could never have enough time to sift through the vast number of alerts issued by SIEM systems and similar tools. To stay ahead of security threats as they happen, GRA provides real-time risk prioritized alerts for incident analysis and triggers an automated risk-response workflow. That lets you automatically neutralize true positive security threats as they occur.

You need to move at machine speed to counter advanced cyber threats. GRA provides the machine-based reaction time that’s critical for containing emerging threats. These automated actions also boost the productivity of your IT security staff by letting them focus on other tasks rather than inefficient manual response intervention.

As the cyber threat landscape continues to evolve, so do the security solutions attempting to counteract the threats. A Zero Trust security approach is one of the best processes to prevent threats from escalating into serious problems.

We invite you to see a demo of GRA. Learn how our unique approach to Zero Trust security can protect you from new and emerging cyber threats, regardless of where they originate.
