Best User and Entity Behavior Analytics (UEBA) Tools

October 28, 2020

Kyle Guercio | esecurityplanet.com

Organizations that want to add advanced analytics or machine learning capabilities to their IT security arsenal are turning to user and entity behavior analytics (UEBA). UEBA solutions identify patterns in typical user behavior and pinpoint anomalous activities that do not match those patterns and could correspond with security incidents.

UEBA: Anomaly-based intrusion detection

Attackers are constantly developing new and complex ways to penetrate networks, especially with the use of artificial intelligence (AI). This has made legacy signature-based systems – which solely detect threats whose signatures and patterns have already been identified – far less effective in securing modern networks.

In contrast, UEBA solutions use anomaly-based intrusion detection. These tools track and recognize what’s considered normal behavior for users, endpoints, data repositories and other network entities. This creates a baseline for standard network activity. The software can then monitor the network and identify anomalous activities that deviate from the baseline. This allows UEBA products to identify new methods of intrusion and malicious behavior, even if it’s not clear what kind of attack it is. UEBA solutions typically do their work after other perimeter-focused security solutions have failed, detecting threats inside the network, including insider threats.

If someone accesses sensitive data they usually don’t, that alone could be enough for a UEBA system to issue an alert. Throw in an odd location, time or device and it begins to look like a potential attack, perhaps through stolen credentials. While it’s possible to limit access through tools like zero trust, malicious behavior on a limited basis is still damaging, so behavior analytics adds an important layer of security on top of access tools.

More and more, behavior analytics is beginning to show up in other security tools like SIEM, network traffic analysis, identity and access management (IAM), EDR, data loss prevention (DLP) and employee monitoring tools, but some standalone products remain. We’ll cover this market trend further in the future of UEBA section following the list of top vendors.

What to look for in a UEBA product

When shopping around for a UEBA solution, there are a few key considerations to look for.

Scalability: Large enterprises collect and store terabytes of data every day. The machine-learning functionality in UEBA solutions uses this data to model behavior patterns and detect anomalies. Only a UEBA solution with an architecture that was designed to support scalability and elasticity will be equipped to monitor and configure this endless stream of Big Data behavior patterns. Otherwise, you could end up spending a lot of money and time scaling with additional deployments and new builds.
Multiple data classes: An efficient UEBA solution should be able to analyze multiple classes of data to gain a contextual understanding of normal and anomalous behaviors. For example, if a solution can identify badge logs, network packets and endpoint logs, it can understand when and how frequently a user is active, how much information they’re accessing, as well as what sensitive information they’re attempting to download. This holistic picture of behavior allows security specialists to confidently take measures to remedy threats.
Streamlined and secure deployment: The most efficient UEBA solutions come with built-in use cases and can be stood up in a matter of days without the need for offsite services to help with configuration and deployment. Not only does this save time and money, but these offsite services often require VPN access to your network, which can itself create security risks or regulatory compliance issues.

UEBA best practices

While UEBA software is a powerful tool, it is not an all-encompassing network security solution. It will take some work for it to operate effectively. Here are a few best practices to keep in mind:

Customized alerts: When anomalies are detected, the UEBA system will send out an alert. It’s important to configure these alerts to only be sent to the relevant team members. Having too many cooks in the kitchen can convolute the remediation process. This also prevents unnecessary panic.
Integrate with other solutions: While UEBA solutions can collect a lot of information on their own, they should not be your only source of data. Integrating them with other monitoring tools such as Intrusion Detection Systems (IDS) and applications like Customer Relationship Management (CRM) systems will provide valuable contextual insight for identifying behavior.
Review reports: Even if you have a lot of trust in your UEBA solution, it’s important to regularly review anomalous activity reports. If there are certain activities that are continuously being incorrectly flagged by your system as anomalous, then you could be wasting valuable time and effort digging into issues that don’t exist and some fine-tuning may be in order.

The future of UEBA

Although UEBA solutions have only been around for a few years, they quickly became popular among large enterprises. However, just as quickly, there is a major shift happening that may eliminate the existence of stand-alone UEBA products altogether.

UEBA market analysis

According to Gartner’s Market Guide for User and Entity Behavior, they predict that the UEBA market will cease to exist as a stand-alone product in the near future. In fact, by 2022, Gartner predicts that as much as 95 percent of all UEBA deployments won’t be as standalone products, but as features of broader security platforms. Gartner currently doesn’t plan to even track UEBA revenue beyond 2020 due to the stark increase in acquisitions, pivots into specific markets or the development of additional features to evolve into a modern SIEM.

There are a few reasons for this major shift:

Use cases: stand-alone pure-play UEBA platforms were typically built to support a broad range of use cases for users, as well as entity behavior analytics. Vendors with embedded UEBA features in their solutions, such as SIEMs, are often tailored to more specific use cases. Most organizations prefer to use technologies that specifically cater to their unique security and business needs.

Deployment and maintenance: Buyers report that the deployment and ongoing maintenance of pure-play UEBA solutions has proven to be time-consuming and labor-intensive. When these capabilities are wrapped up in a more comprehensive solution, all of the time and resources needed to get it up and running and to maintain its operation are consolidated.

Rather than looking at standalone products, you may be better off looking at UEBA as part of a whole, more comprehensive security solution, or one that integrates well with other security tools. Before making a purchasing decision, check whether your existing security vendors already offer UEBA features and advanced analytics in its tools latest release.
