Vectra artificial intelligence augments security operations
Vectra AI meets today’s cybersecurity challenges by blending human expertise with a broad set of data science, machine learning techniques and deep learning to automate the manual, time-consuming work associated with security analysts.
By automating cyberattacker detection, analysis and incident response, Vectra AI condenses days or weeks of work into minutes, reducing the threat investigation workload by up to 29X.
How Vectra AI works
Using behavioral detection algorithms to analyze metadata from captured packets, Vectra AI detects hidden and unknown attacks in real time, whether traffic is encrypted or not. Vectra AI only analyzes metadata captured from packets, rather than performing deep-packet inspection, to protect user privacy without prying into sensitive payloads.
Global learning identifies the fundamental traits that threats share across all enterprise organizations. Global learning begins with Vectra Threat Labs, a full-time group of cybersecurity experts and threat researchers who continually analyze malware, attack tools, techniques, and procedures to identify new and shifting trends in the threat landscape.
Their work informs the data science models used by Vectra AI, including supervised machine learning. It is used to analyze very large volumes of malicious and attack traffic and distill it down to the key characteristics that make malicious traffic unique.
Local learning identifies what’s normal and abnormal in an enterprise’s network to reveal attack patterns. The key techniques used are unsupervised machine learning and anomaly detection. Vectra uses unsupervised machine learning models to learn about a specific customer environment, with no direct oversight by a data scientist.
Instead of concentrating on finding and reporting anomalies, Vectra looks for indicators of important phases of an attack or attack techniques, including signs that an attacker is exploring the network, evaluating hosts for attack, and using stolen credentials.
Vectra condenses thousands of events and network traits to a single detection. Using techniques such as event correlation and host scoring, Vectra performs the following:
- Correlates all detection events to specific hosts that show signs of threat behaviors.
- Automatically scores every detection and host in terms of the threat severity and certainty using the Vectra Threat Certainty Index™.
- Tracks each event over time and through every phase of the cyberattack kill chain.
Vectra puts special focus on events that may jeopardize key assets inside the network or are of strategic value to an attacker. Devices that exhibit behaviors that cover multiple phases of the cyberattack kill chain are also prioritized, as shown below.
Cognito AI blends human expertise with a broad set of data science and machine learning techniques. It delivers a continuous cycle of intelligence based on threat research, global/local learning models, deep learning, and neural networks.
This paper examines obstacles in the fight against cyberattacks and how AI speeds-up detection and response in the SOC. AI augments the work of SOC teams to make operations more efficient and mitigates cyberthreats before damage is done.
