What Does 'NBA (Network Behavior Analysis)' Mean?

Network behavior analysis is a cybersecurity technique that involves the continuous monitoring and analysis of network traffic and activity to identify unusual or malicious behavior.

It is used to detect and prevent cyber threats, such as malware infections, data breaches, and insider attacks, by identifying patterns and anomalies in network activity that may indicate the presence of a threat.

Network behavior analysis involves the collection and analysis of data from various sources, such as network traffic logs, system logs, and security logs. This data is used to create a baseline of normal network behavior, which can then be used to identify deviations from this baseline.

For example, if a user normally accesses a small number of websites during the course of a day but suddenly begins accessing a large number of unfamiliar websites, this could be an indication of a malware infection or other cyber threat.

There are several different types of network behavior analysis, including:

Traffic analysis: This involves the analysis of network traffic patterns to identify unusual or suspicious activity. For example, a sudden increase in traffic to or from a specific IP address or domain could indicate the presence of malware or other cyber threats.

Protocol analysis: This involves the analysis of the protocols used to transmit data over a network, such as TCP/IP, to identify unusual or malicious activity.

Content analysis: This involves the analysis of the content of network traffic, such as emails, to identify malicious activity.

Application analysis: This involves the analysis of the applications running on a network, such as web browsers and email clients, to identify unusual or malicious activity.

Network behavior analysis is an important tool in the fight against cyber threats, as it allows organizations to identify and respond to potential threats in real-time.

By continuously monitoring and analyzing network activity, organizations can quickly identify and mitigate potential threats, helping to protect against data breaches, malware infections, and other cyber threats.
