Behavioral analytics transcends the focused nature of individual security tools to surface the underlying drivers of criminal minds.
User and entity behavioral analytics (UEBA) creates an integrated view of cybersecurity risk generated by an entity‒a risky insider, an infected host, or a compromised account‒by mathematically measuring “unique normal” with contextual intelligence.
Behavioral analytics utilizing advanced mathematical models and unsupervised machine learning can help detect threats, including the following:
Behavioral analytics statistically discovers patterns that create unique digital fingerprints of all entities in an enterprise. Each entity – a person, machine, printer, website, IP address, etc. – exhibits certain characteristics of usage and operation. Understanding the unique, normal characteristics of each entity is necessary to detect abnormalities. In cybersecurity, behavioral analytics is known as security analytics and UEBA.
No two cyber attack vectors are the same. At the same time, existing tools generate a flood of alerts that are overwhelming security operations center (SOC) resources. Behavioral analytics powered by unsupervised machine learning provide defenders with the tools to augment existing data and a prioritized list of threats that matter.
“Unique normal” is the individual digital fingerprint of each entity. Each individual user, machine, IP address, printer, website, etc., have unique patterns of access and operation. This baseline of “unique normal” can then be continuously compared to itself over time to see aberrations.
Interset continuously measures “unique normal” for the following entities types, as well as for its relationship to every other entity: users, machines, IP address, projects, resources, services, shares, websites, volumes, and printers.
Just as every human is unique, so is each entity. Anomaly detection algorithms that expect the same patterns from all entities results in a flood of ineffective false positives. The accuracy of a UEBA solution requires precise measurement of how a unique entity behaves and requires the scalability of machine learning.
The only practical, scalable, and accurate method for measurement of “unique normal” across an enterprise requires unsupervised machine learning technology, a type of artificial intelligence (AI) that automatically discovers patterns from limited datasets. Unlike supervised machine learning, unsupervised machine learning does not require labels (i.e. a “dictionary” for the machine to learn from). Since there is no textbook definition of normal that applies to all entities, only unsupervised machine learning can accurately measure “unique normal.”
Many vendors claim to leverage AI, but the truth is that not everyone actually employs true AI technology. Even within AI, there are many different options, and not all are effective for the problem at hand. The AI techniques utilized to detect modern cybersecurity threats must be able to adapt to the continuously changing cyberattacks, and unsupervised machine learning is a key component of this capability.
Advanced mathematical models measure an entity’s behavior against both unique individuals and mathematically peer group baselines for more accurate threat detection. The analytical models leverage a native big data storage and computer architecture for scalable incorporation of broader contextual information for increased accuracy and a more complete view of risk. Interset’s principled math provides a library of more than 350 proven machine learning and advanced analytical models. These models enable self-learning, consider both events and entities, and create an incredibly accurate way to detect, connect, and quantify high-risk behaviors.
Our principled machine learning approach and advanced analytics framework have been vetted with the utmost scrutiny, as evidenced by our partnership with In-Q-Tel.
