Control 3.3.5: Correlation of Audit Record Review, Analysis, and Reporting Processes


Control Description: The objective is to establish a correlation between audit logs, their review, analysis, and subsequent reporting processes. This mechanism ensures that the system can proactively identify and respond to indicators of potentially unlawful, unauthorized, suspicious, or unusual activities.


Implementation at [Company Name]:

Our approach is facilitated by our integrated SIEM and SOC systems:

SIEM System Purpose: The SIEM (Security Information and Event Management) system acts as an integrated platform offering real-time analysis of security alerts generated by our hardware and software infrastructures. Its design provides a comprehensive perspective on an organization’s information security by collecting, storing, and analyzing logs and security events from various sources, thus enabling efficient threat detection and compliance reporting.

SOC’s Role: Our Security Operations Center (SOC) serves as the nerve center for monitoring, evaluating, and combating cybersecurity threats. Operated by a dedicated team of security experts, the SOC consistently oversees our IT infrastructure to identify, analyze, address, and mitigate potential security incidents. Their expertise is geared towards a proactive approach to security, including advanced threat hunting, forensic analysis, and incident response capabilities.

With the support of our Security Operations Center (SOC) Team, this system guarantees a reduction in false positives and delivers context-rich actionable intelligence.


Security Operations Center (SOC) Team Responsibilities:

  • Our SOC team excels in identifying and prioritizing Indicators of Compromise (IoCs).
  • They systematically assess logs to determine necessary escalation measures and reporting protocols.
  • Management receives email notifications for any flagged suspicious activities. Following this, the SOC team liaises with pertinent departments to confirm and mitigate potential threats.

Response & Remediation Procedures:

The severity of any detected anomaly dictates our course of remediation. In situations that demand heightened responses, we activate our incident response plan protocol, which is tailored to tackle indicators of unlawful, unauthorized, suspicious, or unusual activities.


Company Name]’s Protocol for Handling Security Events Pertaining to CUI:
