Answer: B

Explanation:

Option 1: This option is incorrect. While SIEM systems may perform analysis of network traffic, their primary purpose is not network traffic analysis, but rather log collection and analysis for security incident detection and response.

Option 2: This option is correct. SIEM systems are designed to centrally collect, store, and analyze logs from various systems to detect and respond to security incidents. They provide real-time monitoring, correlation, and analysis of security events, allowing organizations to identify potential threats and take appropriate actions.

Option 3: This option is incorrect. Encryption of sensitive data is not the purpose of SIEM systems. While encryption is an important security measure, SIEM systems focus on log management and analysis rather than encryption.

Option 4: This option is incorrect. User authentication and authorization are not within the scope of SIEM systems. SIEM systems focus on log collection and analysis for security incident detection and response, rather than user access control.
