Benefits:

Early Attack Detection: Proactive monitoring allows you to identify and stop attacks before they cause significant damage, protecting data and systems.

Reduced Risk of Breaches: Early detection enables quicker response and mitigation, minimizing the impact and potential for successful data breaches.

Improved Security Posture: Continuous monitoring helps identify vulnerabilities and suspicious activity, allowing you to address them and strengthen your overall security posture.

Enhanced Regulatory Compliance: Implementing this control can contribute to compliance with various data security regulations and industry standards.

Accountability:

Senior Management: Sets the security tone: Ensure resources, training, and policies are available to implement 3.14.6 effectively.
Reviews and approves monitoring plans: Ensures plans align with organizational needs and risks.
Provides oversight and resources: Allocates resources for monitoring tools, analysis, and personnel training.

IT Security Team: Develops and implements monitoring plans: Defines what to monitor, how, and at what frequency, complying with 3.14.6. Maintains and updates monitoring systems: Ensures systems collect and analyze data effectively. Analyzes logs and alerts: Identifies potential attacks and investigates anomalous traffic. Reports security incidents: Informs management and system owners of potential threats.

System Owners: Understands monitoring requirements: Agrees to and implements monitoring procedures for their systems. Collaborates with the security team: Provides necessary access and information for effective monitoring. Reviews security events and reports: Takes appropriate actions based on identified security incidents.

Individual Users: Uses systems responsibly: Avoids actions that could trigger false positives or compromise systems. Reports suspicious activity: Notifies the Security Team of potential security incidents identified through personal awareness.

Implementation:

Define Monitoring Scope: Identify critical systems, networks, and data to be monitored. This includes both inbound and outbound traffic.

Choose Monitoring Tools: Utilize tools like Security Information and Event Management (SIEM) systems, Intrusion Detection/Prevention Systems (IDS/IPS), and log monitoring tools.

Establish Alerting Rules: Configure alerts for anomalies like unusual traffic patterns, unauthorized access attempts, and suspicious file transfers.

Incident Response: Develop a plan to investigate and respond to security incidents identified through monitoring. This includes escalation procedures and containment measures.

Continuous Improvement: Regularly review logs, refine monitoring rules, and update tools to adapt to evolving threats and maintain effectiveness.
