Step-by-step explanation:
In a cybersecurity context, the acronym SIEM stands for Security Information and Event Management. SIEM refers to a set of tools and technology used to gather and analyze security event data from various sources in order to identify and respond to security incidents more effectively.
SIEM systems collect and correlate security logs and events from different devices, such as firewalls, intrusion detection systems, and antivirus software. They use advanced algorithms and machine learning techniques to identify patterns and anomalies that may indicate a security breach or attack.
For example, if multiple failed login attempts are detected from different IP addresses within a short period of time, the SIEM system can raise an alert to notify the cybersecurity team about a potential brute-force attack.
