Whether unintentional or malicious in nature, user-based threats can have devastating consequences on your organization. While your focus may be on protecting your organization from outside incidents, you also need to guard yourself from insider threats. Despite your best efforts to keep your organization safe — such as providing security training and company best practices — users are often the weakest link in your defenses.
Understanding user behavior is often difficult because there are many different types of users. Complicating matters, you don’t know if your users’ actions are unintentional or deliberate. That’s why you need to add an additional layer of analytics beyond your security information and event management (SIEM) platform with user and entity behavior analytics (UEBA).
It’s important to understand the types of users that exist in your organization and the threats they pose. Because you don’t know what types of users you have, you must scrutinize everyone, regardless of their position in the company. The volume of users in your organization, combined with the fact that incidents can be intentional and unintentional, are key reasons why user-based threats can be challenging to detect.
Let’s take a closer look at different types of users in your organization and how UEBA can help you respond more quickly and keep attacks from escalating.
Typically, users fall into one of four categories:

The intent to cause harm varies with the types of users. While some users (particularly accidental or careless users) may have the best intentions to keep your data safe, these individuals can still cause risk to your organization.
User-based threats can occur from anyone who has access to your network or system. This includes current and former employees, contractors or temporary staff, partners, and third-party associates.
While this reality is scary, there is a bright side — you can uncover user-based threats by focusing on user data and changes behavior with UEBA.
UserXDR gives you the power to not only monitor for known threats and behavioral changes in your user data, but also uncover abnormal authentication behavior and user-based threats that might otherwise go undetected. It detects threats across the full spectrum of known and unknown threats, then qualifies them as security or operations relevant.
LogRhythm UEBA offers scenario- and behavior-based analytics as an integrated component of the LogRhythm NextGen SIEM Platform or as a standalone product. Our UEBA solution not only minimizes the time it takes to detect these threats, but it also helps you rapidly respond before they can result in a devastating breach.
