MICCC Threat Tactics Practice Test

A Security Information and Event Management (SIEM) system is primarily focused on the collection, analysis, and management of security data from various sources within an organization. Its core functions include real-time monitoring of security events, aggregating event data from multiple systems, and alerting security personnel about potential threats based on the security information analyzed.

Data encryption, however, is not typically a function associated with SIEM systems. Encryption is a security measure used to protect sensitive data by encoding it so that only authorized users can access it. While encryption is an important part of an organization's security posture, it is not a function that falls under the purview of SIEM systems, which concentrate on event management and threat detection rather than data protection methods like encryption.
