User And Entity Behavior Analytics in 2018

We’ve all seen big data breaches in the news. We also know there are many more breaches that did not make it into the evening news. The insider attack vector – whether it is a malicious insider, an unsuspecting compromised employee, or accidental misuse, is a common theme across most of these data breaches. According to the 2018 Inside Threat Report by Cybersecurity Insiders 90% of organizations surveyed feel vulnerable to insider threats.

Security environments have historically focused on keeping external actors out, however, according to the 2017 Verizon Data Breach Investigations Report, one out of every four identified breaches involved an internal actor.

User and Entity Behavior Analytics (UEBA) has been specially created to combat these types of threats. As you research UEBA solutions, however, it helps to understand the five core use cases to look for.

  • Insider Threats – Discover compromised users; including actively malicious activity by trusted insiders or innocent mistakes made by employees.
  • Privileged Account Misuse – Monitor accounts with elevated permissions to make sure they are not being used in a manner they are not supposed to be.
  • Cyber Security Threats – Discover if a system in your network starts acting in a way that indicates that it has been compromised or if it is being used in a way it shouldn’t be.
  • Application Monitoring – Discover if your applications start acting in a way that indicates they have been compromised or are being used in a way they shouldn’t be.
  • Cloud Security Monitoring – Discover if your cloud assets start acting in a way that indicates they have been compromised or are being used in a way they shouldn’t be.

At a minimum, these are the five basic use cases that a UEBA solution needs to be able to accomplish. Beyond these five basic use cases, there is a set of key capabilities that your UEBA solution should have in order to address the use cases above.

A basic UEBA solution must be capable of two things at a minimum:

  • Collecting user and entity information from various disparate sources and enriching the data with context in real-time.
  • Applying multiple sophisticated analytics techniques including unsupervised machine learning, peer analysis, and robotic patterning to the information in order to find the anomalies.

An intermediate UEBA solution will go beyond detecting anomalies and include security operations functions so you can respond to threats faster. Such as:

  • Search and Investigation – Easily search and dig down through enriched events, visualize connections between related events, and run ad-hoc reports as needed.
  • Incident Response and Case Management – Semi- or fully-automated incident response playbooks with built-in case management workflows are provided so you can easily take action on alerts. Alternatively, smoothly integrate your UEBA solution with your existing case management tool.

An advanced UEBA solution will expand these capabilities to your cloud environment. With increasing numbers of organizations moving more business functions to the cloud, the ability to extend the same level of security to your cloud assets is critical.
