Systems for Security Information and Event Management (SIEM) are designed in a way such that they aggregate and correlate information gathered from a variety of sources in an organization's IT infrastructure. Their purpose is to analyze log data originating from servers, applications network devices as well as security controls so as to identify any security incidents, policy breaches or operational matters. | User and Entity Behavior Analytics solutions are good at monitoring the behavior of users and devices (like devices, apps) inside a corporate network, creating normal behavior patterns with help of machine learning and statistics and finding deviations seen as a sign of insider threats, hacked accounts or other unmatched activities. | NTA solutions are made for observing and studying the network traffic to monitor and analyze it. They specialize in intercepting and investigating network packets or flow data to find any unusual or criminal deeds inside the network like network incursions, data exfiltration, or lateral movement by attackers. |
It usually picks up data from various sources like servers, firewalls, Intrusion Detection Systems and malware protection systems.') | It examines information from a variety of places like logs, endpoints, applications and network devices and is particularly interested in how people and things behave. | Focuses on network traffic data. Capture and analyze network packets or flow records from routers, switches and other network devices. |
It is possible to identify security breaches by correlating incidents occurring in various places, to reveal irregularities or patterns pointing to possible dangers. | It identifies irregular user behaviors or entity behaviors that are suggestive of security threats, like queer logins times, too much accessing files etc. | Detecting suspicious network activities can be performed by analyzing traffic patterns, anomalies in packet headers or deviations from established baseline network behaviour. |
This can be used for real time tracking, fraud reply, obedience supervision and inspection investigation in the whole IT infrastructure of a firm. | Utilized for the identification of insider threats, compromised accounts, account takeovers, and other abnormalities that the ordinary measures for security cannot detect. | It is mainly used for network visibility, detecting threats in networks, and recognizing potential network attacks. |
Is used mainly for security operations as it integrates well with other tools and gives a complete picture of an organization’s security position. | It could work alone, or by teaming up with SIEMs and other security products to increase in user-focused detection and response features for threats. | Typically it can act alone, but usually affiliates with SIEMs, giving security analysts supplementary context and network visibility. |
